Aerodynamics combined with style. The result is an extremely low co-efficient of drag (0.34).

Elegance from the wind-tunnel The new coupes, the 380 SEC and

500 SEC, have many new features which further improve their practicality.

Further technical development has, to an appreciable extent, determined their shape. Their contemporary profile results from the integration of function and style, not from undisciplined extra­vagance.

Intensive efforts to lower the co­efficient of drag even further have re­sulted in more than a reduction in fuel consumption.

The results are obvious at first glance, from the smooth line of the body-shell and the absence of sharp edges and corners.

Shaped for a purpose Seen from the side, the body is

wedge-shaped; the bonnet is sloped and the boot lid is higher than the bonnet. The front roof-pillars are aerodynami­cally angled and shaped. The roof slopes down towards the rear. These

visible modifications result in invisible, but very effective, improvements in im­portant areas.

They reduce lift-forces at the front axle, improve road-holding, and the driver has an even better view of all four corners of the car.

The coupe concept has, of course, helped in achieving the low co-efficient of drag.

Styling features of the coupe are frameless side windows, aII of which can be fully recessed. Side windows in the rear that can only be wound half­way down are a compromise that Mercedes-Benz would never accept.

Because there is no centre pillar, the view to the sides is not obstructed. Forward visibility is also generous, and fully-recessed wipers sweep 76°/o of the screen.

Front roof·pillar with recessed rain runnel. An aerodynamically·shaped Door·handle set in dirt-deflecting panel. There is a rain-water oullet rear-view mirror which is adj ustable from inside the car. in the barrel of the lock.

Halogen headlamps and wrap-around indicators. Fog-lamps.

A beautiful shape, both functional and emcient

A number of detail f ea tu res protect the bodywork against minor damage. For example, front bumpers shaped like spoilers; these also reduce lift-forces at the front axle.

The shield extends along the sides of the car in the shape of deep protec­tive panels, and to the rear. Bumpers and side panels are made of light, yet highly durable material and are easily replaced.

Another example of the co-ordina­tion of aII of the features is the front fog­lamps, with their "stepped" lenses, which are integrated into the lower bumper panel, so that they are protected against damage from gravel or minor impact, as weII as being positioned in the right place, close to the ground.

For easy access, the light-alloy boot lid opens to a generously wide angle. Boot-capacity is the same as in the S-class saloon, 0.505 m3 (17.6 cu.ft.).

Recessed windscreen wipers. lNilh overload protection.

A wide range of colours To enhance the individuality of the

new coupe, there are twenty-six dif­ferent paint colours to choose from, eight standard colours, nine special shades and nine metallic finishes.

In the rear. two single seats. with folding centre armrest and oddments tray.

Large, wide-opening doors make access to the front seats easy. When the driver's door is open, the vacuum lock­ing mechanism of the front seat backs is released automatically. Rear-seat pas­sengers can also get in without trouble, they have individual seats.

Space, in the front and in the rear, is appreciably greater. There is more headroom in the rear. The slightly "step­ped" shape of the backs of the front seats gives rear-seat passengers even more room to move.

The seats, with their steel spring cores and "breathing" covers, are soft enough to be comfortable, but suffi­ciently firm to give the body support on long journeys and to ward off fatigue.

Both front seats are electrically adjustable to eight different positions, for perfect comfort.

Exclusivity is also expressed by the standard of interior equipment in the two coupe models. Seats covered in a new, striped velour, available in eight different colours. As optional extras, you

can choose from velour in three different two-colour combinations or leather in eight colours.

Electrically-operated windows are standard equipment, the rear side win­dows can be operated from either the front or rear of the passenger compart­ment.

When the doors have been closed and the ignition turned on, the seat belts are automatically moved towards the driver and front-seat passenger by means of belt-guides. They can, there­fore, be fastened even more easily.

When the belts have been fastened, the belt-guides return to the rest position, on the driver's side and on the passenger side after some thirty seconds. Another example of the large number of practical features is the third sun visor, which is behind the rear-view mirror, so that a low sun can no longer dazzle the driver.

Available as an optional extra. the eleclronic automatic lemperalure control system.

Electrical seat heating is an optional exlra. You cannol always park your car in a garage.

A car can demonstrate its sports-car attributes in many ways, one of the least desirable is by excess noise. Not in a Mercedes coupe, where you can talk to all of your passengers without raising your voice, even when travelling at high speeds.

Double door seals, a bulkhead between the engine and the passenger compartment and low noise levels from the engine and transmission all make the car more quiet.

In a Mercedes coupe, you are insulated from traffic-created stress

The "climate" inside the coupe helps to create that unique feeling of well-being.just as it does in an S-class saloon.

This is essentially due to the re­markable electronic "Heatmatic" control system which allows the temperature to be adjusted exactly to the required level - independently for each side of the car.

Driver and front passenger can set the heating to any temperature between

Wilh this swilch. the fronl seats can be adjusted. eleclrically, lo eight dilTerenl positions.

16° and 32° C (60-89,6° F). Once the desired level has been reached, it is, in principle, maintained, regardless of out­side temperature and road speed.

Other features which also contri­bute are the heating ducts inside the doors and the advanced ventilation system with its four-stage booster and distribution control.

Rear-seat passengers have their own supply of fresh air, through an acijustable inlet in the centre console.

Air conditioning (an optional extra) is, when fitted, integrated into the stand­ard heating and ventilation system. The cooling, as well as heating, can be pre­set and controlled automatically and separately for each side of the car.

Ergonomically designed instruments, positioned to reduce driver-stress

Today, a driver has to concentrate even harder, whether on long journeys or in congested city traffic.

Ergonomically designed, logically­positioned instruments and controls go a long way toward minimising the inevi­table stress.

Switches and levers that are ob­vious in their function and cannot be confused one with another. Instruments that can be read at a glance, by day or by night.

In a Mercedes, there are, as a matter of principle, no technical gim­micks to distract the driver and to go wrong.

On the contrary, to benefit the driver, Mercedes-Benz have been endeavouring to reduce the number of controls. One example of this is the combination lever on the steering column, which operates the indicators, the three-speed wipers, the screen-

The T er'npomat contributes not only to greater comfort, but also to greater fuel economy; you can monitor this with the fuel-consumption trend in­dicator.

A central locking system is stand­ard on the new coupe; it is reliable, be­cause it operates on the dual-pressure principle.

A balanced relationship between energy input and power output. the light-alloy VB engine in the Mercedes 500 SEC.

The new coupe is offered with a choice of either 3.8 or 5-litre light-aIIoy power units.

These engines have been further developed, as part of the Mercedes-Benz Energy Concept, and include many trend-setting ideas.

Engines with new fuel-consumption characteristics

The 3.8 litre engine in the 380 SEC has different bore and stroke dimen­sions. The compression ratio has been raised and, with a modified chamshaft, fuel consumption has been improved. Maximum torque is produced at only 3250/min (previously 4000/min). It develops 150 kW (204 DIN/hp) at 5250/min.

In the 500 SEC, the 5-litre engine, too, has a higher compression ratio and a modified camshaft, as weII as other improvements. Maximum torque is pro­duced at 3000/min (previously 3200/min), and it develops 170 kW (231 DIN/hp) at 4750/min.

The result of all these features is a lot of power at lower engine speeds, consequently smooth running, low noise levels and resistance to wear. Con -versely, because of the engine character­istics, their reassuring reserves of power can be used very quickly.

These common-sense economies have not been achieved at the expense of performance, nor of the pleasure you are entitled to expect from a Mercedes coupe.

The Mercedes-Benz Energy Con­cept consists of a large number of inter­related details; here are some further examples.

Modified cooling system If an engine can reach its operating

temperature more quickly, there is less emission of pollutants and fuel con­sumption is reduced.

To this end, the warming-up time has been shortened, because the coolant does not come into use until a higher temperature has been reached. When

the engine is cold, the coolant does not circulate at all. At a temperature of 84 ° C (183° F), the thermostat opens part of the circuit and only at over 100° C (212° F) is the coolant circuit to the radiator used.

Electronic idling-speed control When driving in town, the engine

idles, on the average, for 31°/o of the time.

Therefore, the new electronic idling­speed control goes a long way in reduc­ing fuel consumption.

With a warm engine and the trans­mission in the "Drive" position, this con­trol keeps idling speed down to about 500/min.

In combination with the modified camshaft and improved fuel atomisa­tion the new control reduces fuel con-

' sumption at idling speeds by more than 40°/o.

Hydraulic fan coupling Because the fan coupling has a

double control system, it comes into use less often, therefore reducing fuel con­sumption as well as lowering noise ievels.

Automatic transmission with new ratios

Both coupes are fitted with proven four-speed, torque converter automatic transmission. The shift-pattern has, as part of the Mercedes-Benz Energy Con­cept, been modified to match the higher ratio of the rear axle.

The new gear selector. with the additional ·s·· position.

As a result, the fourth gear has the effect of an overdrive.

This makes the car even more economical, the ride even more com­fortable, and eliminates jolting when gears are changed.

The 380 SEC always moves off in first gear, the 500 SEC pulls away in second, although first gear can be engaged by the kick-down.

A new feature on both models is the addition of position "B" on the gear selector. This enables the driver to re­main in first gear at speeds up to 55-60 km/h (34 - 37 mph). This is a great advantage, for instance when go­ing down steep hills with a trailer; it allows the driver to make full use of the engine braking effect, which would be reduced if the transmission shifted to a higher gear.

Higher rear axle ratios. One aspect of the Mercedes-Benz Energy Concept.

Front suspension, with zero-offset steering. larger-diameter springs and an improved system of wishbones and torsion bars.

The manoeuvrability of a coupe, the comfort of a saloon

In the new coupes, the suspension is similar to that of the S-class saloon.

It has been perfected to a degree that makes it difficult to visualise further fundamental changes.

The wheelbase of the coupe is, of course, slightly shorter. This, together with the light, yet very accurate power­assisted steering, makes the car even more manoeuvrable.

A turning circle of only 11.53 metres (37.8 ft) is the practical benefit of the wide lock on the front wheels.

Reduced fuel consumption, improved comfort

To match the characteristics of the modified engines, the rear axle ratios are now higher. Ratios in the four-speed automatic transmission have, in turn, been changed, to suit the rear axle.

Because of these modifications, engine speeds are now lower, in every gear, for the same road speeds, than in

New, floating-caliper disc brakes.

the previous models. Lower by 24°/o in the 380 SEC and by 180/o in the 500 SEC.

This, too, contributes to a reduction in fuel consumption and in noise-levels, and makes the car more comfortable.

The brakes. Less heat, less chance of fading

Both coupe models have a dual­circuit, servo-assisted braking system, with discs on all four wheels. At the front, newly-designed floating-caliper disc brakes.

Because the brake-fluid lines are positioned w ell away from the pads, the fluid is less likely to become hot.

Diameter of the front discs has been increased by 8 mm to provide even greater stability.

The front discs have interior ventila­tion and there are ventilation rings in the wheels to dissipate heat more quickly.

,

The electronically cont rolled restraint system which includes the airbag and the belt tensioner.

The anti-lock braking system {ABS). available as an optional extra.

Active safety The mature suspension system,

with its great reserves, is the basis of active safety.

Accurate straight-line stability, no excessive tendencies towards oversteer or understeer in corners, light yet posi­tive steering, meticulously tuned suspen­sion and damping enable the driver to react quickly, prevent the car from breaking away suddenly and ensure safe road-holding.

Another substantial contribution to­wards active safety is the anti-lock brak­ing system, which is available as an optional extra.

Irrespective of road conditions, it prevents locking of the wheels under hard braking. So, steering response is retained, even while braking.

When used by a considerate driver, the power reserves of the eight-cylinder models can be activated within split seconds and serve as an element of active safety.

Belt-guides automatically move the seat-bells towards the driver and front -seat passenger.

Passive safety Mercedes-Benz have for more than

forty years been pioneering the develop­ment and the further refinement of safety systems.

Further proof of their innovation in the vitally important field of passive safety is illustrated by the electronically­controlled restraint system, elements of which are the airbag and the belt ten-. s1oner.

Mercedes-Benz are the first manu­facturers to off er, as optional extras, these two units, which further reduce the risk of injury to front-seat occupants in a head-on collision.

The airbag and belt tensioner are complementary to the inertia-reel three­point seat-belts.

The airbag inflates, cushions the driver and then deflates again - all within fractions of a second, even before the driver can register what is happen­ing.

\\

A few milliseconds after a severe impact, the seat-belt tensioner pulls the belt tight against the passenger.

The front section gives protection against the effects of impacts in three progressive stages. The first zone yields most easily; it reduces the impact of the collision, sometimes for the occupants of the other car as well.

· The second zone, the engine area, offers increasing resistance to def orma­tion, and the third zone, the passenger safety-cell, has a very high degree of rigidity.

The roof pillars combine with the front section of the roof itself into a very strong, integrated unit which offers pro­tection, should the car roII. The pillars are specially reinforced, there are tubes inside, a protective measure which is especially suitable for the coupe shape.

Floor and sides are extremely rigid. Door frames, doors, hinges and locks form an integrated protective shield which prevents excessive distortion in

the event of a lateral impact, as well as avoiding jamming of the doors.

The fuel-tank is located in a well­protected area, over the rear axle; there is a bulkhead between it and the pas­senger compartment.

Protection for other road users in­cludes the driver-controlled headlamp beam adjustment, and the windscreen wipers which are recessed when not in use.

The new coupe Progressive engineering and traditional Mercedes virtues To drive the new coupe is to expe­

rience the quality of engineering and to enjoy the elegant styling which establish new standards for years to come.

The further development of signifi- · cant concepts and their realisation in practical terms has been achieved re­sponsibly and economically.

Continuous research on the Merce­des-Benz Energy Concept has resulted in appreciable reductions in the con­sumption of energy and materials.

And the traditional Mercedes vir­tues still remain: quality in design, mate­rials and workmanship; durability and very high re-sale values.

Long life Contribution to value retention are

the additional protection against cor­rosion and the use of light-alloy and plastic components that do not rust.

Plastic liners are fitted under the front wheel arches as protection against damage by salt and stones.

A protective coating on all front sections susceptible to damage from gravel, etc. The undersic!e of the floor is coated with a lighter, but highly resistant material.

Efficiency and durability of the ex­haust system have been generally im­proved. The sections between the si­lencers are in high-grade steel.

Hollow sections (which become in­accessible after assembly) receive a coating of adhesive wax with special "creeping" properties.

Safety and value-retention, through after-sales service

By the utilisation of every possible technological process, Mercedes cars have become even more reliable, even easier to maintain, and repairs cost even less.

Quality is not a matter of chance: the latest in technical aids.

Quality is not a matter of chance: employees trained to perfection.

For example, brake master cylin­der, battery, relays and fuses are pro­tected in a compartment under the bon­net. Oil filter, all light bulbs, booster, cooler and piping of the heating system are read.Uy accessible or easy to remove. Body panels, especially at the front, can be repaired individually, to save cost. Front wings are bolted on. Longitudinal profiles divide the roof into sections, to reduce the amount of re-spraying, should it be necessary.

Longer service intervals Major service only once every

20,000 km (12,500 miles). Proof of reli­ability, and a contribution to the eco­nomy of Mercedes cars.

Servicing can be carried out by any one of 1,200 dealers in Germany; there are 5,000 service points world-wide.

THE TRADITION OF

EXCLUSIVITY.

The large coupes with the three-pointed star. One of the major traditions in the history of the car. And one of the few that have re­mained alive and still valid. A concept that has expressed the highest standards of the Mercedes-Benz marque - for decades.

Time and again, Mercedes coupes have been the high points in international auto­motive design. Symbols of exclusivity, due to their superiority, their style and their first­class engineering. Over the page are three historic examples of this individuality, at its highest level.

THE INDIVIDUAL SHAPE OF CON-

TEMPO RY MOTORING REFINEMENT.

The S-class coupes: the entire engineering potential of Mercedes-Benz at its most exclu­sive-in its most refined form. Sporty, elegant expressions of supreme leadership in modern automotive design. A distinctive, in­dividualistic and b alanced shape.

Highly positive in its appearance. Rare and eyecatching. A clean, sleek shape; powerfuJ lines. An accent on performance, with a radiator star similar to that of the SL models. Long side windows, with no centre pillar to interrupt the visibility.

Dynamic motoring, yet refreshingly light steering. A superbly successful combi­nation of sporty, exclusive style and automo­tive practicality.

The dynamic appearance is matched by the power from the V-8 engines. An ideal and highly efficient combination of large swept volume within the right number of cylinders.

Dynamic performance, for sheer motor­ing pleasure - with a suspension system which turns the power into relaxing active safety.A driving position withoutgimmicks­for maximum comfort and alertness, for excellent steering control, even when driv­ing fast. A feeling of ease which matches the style of the car.

Then there are the classic virtues. Durability, reliability; passive safety which sets the standards worldwide. Exclusivity, even in day-to-day motoring, and, as part of its contemporary concept, economy and environmental acceptability.

The taut shape of the coupe; lower than the saloon, and wider - with an even lower centre of gravity. The wheelbase is almost ten centimetres shorter, for even better manoeuvrability.

An attractive symbol of classic coupe elegance; fully retractable side windows without a centre pillar to interrupt visibility. The rear side windows are shaped to inte­grate smoothly into the flowing lines of the rear section of the bodywork - typical coupe lines.

The elegance is totally in unison with the purpose of the shape. Functionality and practical benefit in every detail, with scarcely any wind noise, even at high speeds. An in-

terior that does not heat up excessively in the sun, despite the aerodynamically shaped body. Excellent all-round visibility. A bon­net that slopes up towards the windscreen, with fully recessed wipers. Water deflectors on the front pillars and along the roof.

Large ligh t units, ribbed at the rear to prevent the accumulation of dirt. Fully inte­grated, flexible bumper system. Low aprons front and rear reduce lift forces even further. And 15-inch wheels with attractive hub caps, with light-alloy wheels as an optional extra.

PERFORMANCE AT A NEW,

EXCLUSIVE LEVEL. Three models, one engine concept - the range of proven lightweight V-8 engines. Masterpieces of modern design. With cubic capacities of 4.2, 5 and 5.6 litres in the three models: - 420 SEC, 500 SEC and 560 SEC.

One aspect shared by all of them is their further-developed power-potential. New, dyna1nic performance figures; significant increases in power. An effortlessly-available 220 kW (300 hp) in the 560 SEC, for example. Power that you can experience in the acceleration - true dynamic power.

With Mercedes, the decisive factor is the way the performance is delivered. Majes­tically smooth yet instantly responsive power at all engine speeds. And, therefore, in all situations. The most important factor is the large swept volume, rather than the number of cylinders. The superior "breathing" ensures h igh torque, even at low engine speeds. Providing performance-capability righ t where it is most needed.

This adds up to sparkling yet smooth motoring pleasure and active safety- and not just when you have the road to yourself. Sporty dynamism which is barely audible -exceptional ride comfort, with powerful acceleration that does not come at the expense of high fuel consumption even when the power is used to the full. Because, today more than ever before, first-class engineer­ing also means maximum utilisation of energy.

A further contribution to low fuel con­sumption is the electronic control of a num­ber of basic functions: the ignition and injec-

tion systems are microprocessor-controlled. This means constant, automatic and precise adjustment of the ignition timing and the mixture formation under all driving and load conditions and in all throttle positions. 420 SEC: 170 kW (231 hp) at 5400/ min. Fuel consumption: 15.l litres per 100 km on the urban cycle,8.7 litres per lOOkm at a con­stant 90 km/ h, 10.7 litres per 100 km/ h at a constant 120 km/ h. 500 SEC: 195 kW (265 hp) at 5200/ min. Fuel consumption: 15.8 litres per 100 km on the urban cycle, 8.8 litres per 100 kn1 at a con­stant 90 km/h, 11.1 litres per 100 km/h at a constant 120 km/h. 550 SEC: 220 kW (300 hp) at SOOO/n1in. Fuel consumption: 16.8 litres per 100 km on the urban cycle, 10.5 litres per 100 km at a constant 90 km/h, 12.7 litres per 100 km at a constant 120 km/ h.

So, engineering leadership in the engines, as well. Matured over millions of kilometres of testing - and therefore highly reliable and with legendary durability, even when used hard .

TOTAL CONTROL.

The big coupe is a car for drivers who really enjoy driving. Its character and performance are distinctly sporty and the suspension is a fundamental part of the concept: a total syn­thesis of stability, ride comfort and active safety. Relaxed control however hard you drive. Highly accurate steering, even when cornering at speed. The unexpected can he handled with consummate ease, and even extremely bad road surfaces are comfortably neutralised. You can actually feel the engi­neering maturity of the car- the "fine-tuned" springs and shock-absorbers, the low centre of gravity, the remarkably wide track. The highest standards of manoeuvrability, effort­less steering control, even in crowded city traffic - due to the relatively small turning circle and the specially light Mercedes power-assisted steering.

Standard on the 560 SEC: self-levelling rear suspension and a limited-slip differen­tial. Optionally available on the 420 SEC and 500 SEC.

The transmission and the braking sys­tem continue to set standards of engineering. Highly efficient dual-circuit servo-braking system. Fixed-caliper disc brakes on all four wheels. ABS as standard. A brake booster for precise, gentle yet highly efficient braking power. Low-profile 15-inch wheels for maxi­mum stability, emphasising the car's power­ful, elegant appearance. All three coupe models are fitted as standard with four­speed automatic transmission. With two dif-

•

ferent shift programmes, for a more dynamic style or with the transmission shifting up ear­lier, for more economical driving.

ASR: electronically-controlled automatic acceleration skid control.

ASR allows the excellent handling qualities of these exclusive cars to be used to the full, even under more difficult conditions. On bends, when taking evasive action, when accelerating hard, or when moving off uphill, perhaps on snow. The driven wheels do not spin and the car does not skid off course, even if the driver accelerates too hard. With the "electronic accelerator pedal", each driven

wheel is automatically given only as much power as the road adhesion can take and con­vert into forward movement. This further improves active safety, in all driving situa­tions.

The new and essential aspect of ASR is that it works electronically and automati­cally. It engages and disengages itself - but only whenever, and for as long as, it is actually needed. The electronics make the correct decision in all circun1stances, without any effort from the driver. An indica­tor in the speedometer tells him that the sys­tem has been activated, so he can then adjust his driving to suit the conditions.

ASR and ABS should go together as a system. Then the wheels do not spin when cornering or accelerating, and do not lock when braking. An ideal combination.

A SPACIOUS ATMOSPHERE OF

ELEGANCE. Exclusivity - even in everyday motoring -the special Mercedes coupe concept. For this reason, a pleasing in terior and a clear infor­mation system determine the design of the driving position. Non-dazzle instruments and gauges, with all the controls ergonomi­cally designed and positioned, within easy reach and easy to operate. A seating position designed for comfort at the wheel. For relaxed concentration and alertness on long JOUrneys.

Full con trol of the car, stress-relief and motoring pleasure. The steering wheel and the gear selector are leather-covered. The two front seats give clecid edly positive lateral support-without limiting freedom of move­ment. Firm, yet very comfortable seat-spring­ing. Electrically-adjustable seats (and head­resu·aints) for the driver and the front pas­senger. Memory feature as an optional extra (standard on the 560 SEC), to store two seat positions.

When the ignition is switched on, belt guides offer the seat belts in a position con­venient for front-seat occupants.

Further examples of detail-features in­clude monitor displays for fuel, engine oil, coolant, screen-wash fluid and for all the exterior light bulbs. Timely warning of wear on the front brake pads. Screen-wash system, screen-wash nozzles and exterior mirror heated. Courtesy light with reading lamp for front-seat passenger. Central locking with multi-point operation.

The impression of space inside the b ig coupes. Firstly, the sporty, elegant overall impression with the sleek contours of the side windows, uninterrupted by any centre pillar. Clean lines, the typical, individualistic atmosphere of a coupe, yet still generous freedom of movement, for rear-seat passen­gers too.

The interior: a superb blend of modern styling, subtly built-in safety features, high­quali ty materials and meticulous workman­ship. Fully developed details, totally inte­grated into an overall entity, giving a com­plete impression of style, as typified by the generous and tasteful incorporation of fine woods. The feeling of security is in1111ediately apparent, as is the dyna1nic character of this h igh-performance car - the most exclusive expression of Mercedes con1fort for long JOUrneys.

Another high point of the interior design is the pair of attractively-shaped, indi­vidually-con toured rear seats. Folding centre armrest. Seat belt buckles recessed yet

. easy to reach. And an example of climate technology that has been thoroughly refined: an electronically-controlled heating system with a recirculating-air facility; this can be used either for faster heating of the interior or to reduce the amount of ambient air used, in the event of troublesome dust or exhaust fumes.

The range of optional extras includes the airbag system for the driver and the front passenger, the trip computer, an electrically-

operated rear-screen blind and the Mercedes Sound System, with specially co-ordinated, balanced technology.

And further optional extras which are standard on the 560 SEC; heated nearside exterior nlirror, sun visors with illuminated mirrors, electrically-adjustable steering colunm (with memory), electric tilting/ slid­ing sunroof. Air conditioning, stereo radio/ cassette player, automatic aerial.

WIDER DIMENSIONS TO SAFETY.

A masterpiece by Mercedes designers. The comprehensive safety system is integrated almost invisibly into the elegant shape.

There is n o other car in the world that offers such a high degree of safety. The knowledge of proven reliability, the active safety features which include keeping the driver fit and alert. And above all the exemp­lary passive safety system. Genuine protec­tion, should the worst come to the worst- but also a relaxed feeling of comfort.

The safety system. For Mercedes, this means the comprehensive and fully-inte­grated interaction of many protective fea­tures. Throughout the whole car, to meet any contingency. Only in a Mercedes is there a system this comprehensive - d ue to decades of research an d development work, with a unique level of investment. A huge asset for the driver - developed in part because the big coupes often cover considerably more kilometres per year than other cars.

Pre-determined deformable crumple zones front and rear. The fuel tank is located in a safe position above the rear suspension assembly. Despite the coupe design, an extremely strong, rigid passenger compart­ment. Highly rigid along the sides and in the roof section. Electronically-controlled belt tensioners on both front seats as standard. Mercedes safety steering with a deformable corrugated tube, steering wheel with impact absorber and padded boss. Instrument panel and all internal controls designed to yield on i1npact. Also, preventive features such as the monitor light for the entire exterior ligh ting system.

And a further example of pace-setting Mercedes safety: as an optional extra, the air­bag system for additional protection. Now with an additional airbag for the front passenger. Logical application of matured electronics.

TOP UALITY FROM CONTINUOUS

DEVELOPMENT.

The exclusivity of the big Mercedes coupes is an enduring characteristic. In engineering terms too, due to designs which will set the standards for many years to come. Due to a shape which determines the style for their class; sporty elegance which points the way forward. And due to their dynamic yet time­less appeal.

The Mercedes principle "committed to the best" is particularly relevant to the cars. The new range, introduced in 1985, is a prac­tical example - further-developed engines for all models, with trend-setting electronic control systems; the more powerful style of the exterior lines, and the further refinement by the inclusion of important new features, from the electronic belt-tensioners on both front seats through the monitor for all ex­terior lights to details such as the unique electric adjustment of the front head­restraints. And now the increased power out­put of all three coupe models.

Continuous Mercedes progress goes

together with improvements in quality and value retention. There is no either/ or. Lighter materials are used only where they also provide increased strength. New, better materials are only applied where they increase durability. Electronic production control and advanced testing methods to provide even greater precision. Interna­tionally respected research work such as the use of the driving simulator - allowing experi­ments which were not even conceivable a few years ago. Computer-aided design; materials tested by data-controlled torture tracks, climate chambers which reproduce extreme conditions. All this creates the certainty that innovation also signifies the further develop­ment of classical quality.

Nowadays, only manufacturers who combine exclusivity with a responsible approach can lay claim to first-class engi­neering. So the big Mercedes coupes are models of economy. The economy of the new, more powerful engines, the maturity of

the design, the maintenance-free 1najor com­ponents and the long service intervals make the cars exceptionally practical.

A degree of reliability which minimises ti).lle off the road and unexpected costs. Cor­rosion protection also fulfils the highest standards - electrolytically-galvanised sheet­steel panels, electronically-tested cavity seal­ing, a bodyshell protection system with multi­layer paint treatment. And value retention, due to the high standard of Mercedes-Benz service - with around 1000 service points in Germany and over 5000 all over the world. With fully trained, dedicated personnel and rapid parts supply. Mercedes customer ser­vice also contributes to the reputation of these exclusive cars.

1 The Mercedes paint system is applied in one of the most, up-lo-date facilities in the 'world. The subsequent polishing, followed by thor­ough mantwl .finishing, gives the cars theirflnal lustre.

2 The body , computer-con­trolled precision. Yet there are still "per.~onal" checks at the end, by eye and by touch.

3 Advanced technology in combination with mcunwl skills. For example, when.fit­ting the Ji 11ely-rnade wood components.

THE WIDE, PERSONALISED

NGE.

The exclusivity is inherent and the indivi­dualistic coupe shape is matched by fully comprehensive equipment and trim. Electric seat adjustment, for instance, and central locking that can be operated from both doors and from the boot. A generous standard spec­ification, an asset to any coupe owner, follow­ing the Mercedes principle of maximum practical benefit from bumper to bumper.

Beyond this, customers can decide for themselves what they, personally, prefer in the way of extras. They can decide on the specification of their own car in finalising their own ideas of comfort and convenience. From a range of optional extras which in­cludes a car telephone, the headlamp wash/ wipe system (standard on the 560 SEC) and

automatic climate control, to high-quality leather upholstery which you can specify for the top 5.6-litre model at no extra charge.

The whole range of individual extras fulfils Mercedes standards of quality. Matched to the functionality of the car, right from the design stage, so that they are inte­grated fully into the overall style.
