T he De Tomaso Guará was firstunveiled back in 1994, and at thetime it represented a giant leapforward for De Tomaso who,

Ferrari F-355 and the Porsche 911Turbo, the Guará represents the high-water mark of De Tomaso engineeringachievement. Starting with a cleansheet of paper, De Tomaso engineersdesigned a new chassis that was a com-plete departure from the Pantera, andin fact hearkened back to the earliestDe Tomaso design, the Vallelunga. For2001, the car has received a few subtledesign updates which warrant givingthe car a detailed look.

The heart of the Guara is its uniquecentral spine, a sophisticated trapezoi-dal-shaped extrusion of aluminum andcomposite honeycomb, whose hollowcenter doubles as the car’s 21-gallonfuel tank. A lightweight alloy subframebolts to the front to support the front

with the Pantera, had spent the previ-ous 25 years building what was essen-tially the same car. While the Panterawas certainly state-of-the-art in theearly ‘70’s, it had grown decidedly longin the tooth by the time productionceased in 1991, although admittedly theNuevo Pantera did boast some usefulchassis improvements.

Rather than making another smallevolutionary design change, De Toma-so was determined to once again re-es-tablish his company as a maker of cut-ting-edge cars. Designed to competein the marketplace with the likes of the

Massive four-piston front caliperssqueeze 13-inch venti-lated and cross-drilleddiscs, while smaller,lighter rear calipers anddiscs (ventilated but notdrilled) are used in therear. They are actuatednot by a power-assistedservo, but rather by twoconventional non-powermaster cylinders work-ing in tandem, for supe-rior pedal feel and infi-nite front/rearadjustability.

The Guará was originally engi-neered to utilize a 4-liter all-aluminumBMW V-8, but shortly after productionbegan, the 4.6 liter double overheadcam four-valve Ford V-8 became thepowerplant of choice. Originally pro-ducing 305 horsepower, the latest ver-sion features subtle internal tweakswhich boost the power to 320.

The early Guarás utilized a Getragsix-speed gearbox whose input shaftdidn’t line up properly with the engine,requiring the use of an intermediatetransfer gear between them. This hadthe effect of altering the gearing to ren-der first gear so low as to be almost use-less, and also generated an objection-able howling noise. The current pro-duction cars use a different designwhich eliminates any such engineeringcompromises.

The design of the body has neverbeen formally attributed to any indi-vidual or design house, but it is rumoredto have emanated from a firm known

as Synthesis Design in the Turin area.The body is formed in several piecesout of a sophisticated composite mate-rial (but not carbon fiber.) The car hasrecently been facelifted with a new nosesection which features two deeply scal-loped vents to help extract hot air fromthe radiator. This is the second time

the nose has been changed; originallyit was rather plain with no venting what-soever, then later one wide, broad ventwas introduced.

Considerable time was spent on thedesign of the interior, which is vastlysuperior to any previous De Tomaso au-tomobiles. Due to the early association

with BMW, virtually all the instru-ments, controls and vents are lifted di-rectly from the 5-Series BMW, whichis decidedly a good thing.

Fine leather is used throughout,with suede atop the dashboard to pre-vent unwanted reflections. The dash-board has two pods, one containing the

The shift knob is a workof art in itself, machined frombillet aluminum. It goes with-out saying that a proper Italianchrome shift gate is used to de-lineate the six forward gearsplus reverse.

The seats are importedfrom Germany minus seat cov-ers; they are then covered withthe same leather used to line thecabin. They are thin and light-weight, offering ample supportand telegraphing road feel to

The Guará Barchetta is actually thefirst model produced, and draws muchof its inspiration from the short-livedMaserati Barchetta (which was de-signed and built at the tail end of DeTomaso’s ownership of Maserati, andshared the basic chassis design with theGuará which followed.) Mechanicallyit is identical to the other versions ofthe Guará, but it is a stripped-down,minimalist pseudo-legal race car for thestreet as opposed to a high-performanceGT car. Lacking anything not directlydedicated to the missions of going, turn-ing or stopping, it weighs in at a mere2314 lbs.

Historically, Barchettas weresmall-displacement, lightweight Fer-raris designed for competition in long-distance road races such as the MilleMiglia and Targa Florio. Barchetta isItalian for “little boat”, and the carswere so named because they resemblednothing as much as an overturned row-boat. They were equipped with the bareminimum equipment to make themroad-legal, but they offered absolutelyzero amenities; windscreens were usu-ally minimal at best.

The Guará Barchetta differs fromthe standard model most obviously bythe complete lack of any wind protec-tion whatsoever. The body is config-ured in a manner that would seem toinvite the fitment of a simple, short,curved windscreen, but curiously noneis normally installed.

All of the carpeting and sound-deadening is absent, as well as the in-terior leather. Since there are no sidewindows or window mechanisms, thedoors are feather-light. The standardseats are replaced by extremely support-ive Sparco racing seats. The modern-appearing steering wheel of the coupeis replaced with a classic ‘70’s three-spoke Momo wheel. The instrumentpanel is lacking most of the instrumen-tation found in the coupe; only a ta-chometer, speedometer, oil pressuregauge and a few idiot lights are in-stalled. (Curiously, a fuel gauge isdeemed unnecessary!)

Driving the Barchetta is certainlyan eye-opening experience. Italian lawdictates that anyone driving a car with-out a windshield must wear a helmet,so if the appearance of the car wasn’tdistinctive enough, that alone guaran-tees attention!

The deep seats are considerablylower than the stock seats, and as a re-sult, the top of the door is practically ateye level and the steering wheel seemstoo high. The experience is not unlikewhat a ten-year-old feels when sittingbehind the wheel of daddy’s car!Oddly, no center rear-view mirror is fit-ted; instead a curious aerodynamic de-vice is nestled between the two dashpods, nominally to smooth airflow intoand through the cabin. This means thatthe door-mounted mirrors take on evengreater importance. Due to the driver’s

low position in the car, the mirrors areabove eye level, again adding to the oddfeeling.

All this is forgotten the momentyou turn the key. The engine lightsimmediately, and due to the lack of anysound absorption material, every hum,buzz and click is transmitted directly tothe driver’s ears along with the melo-dious exhaust note.

The car feels palpably lighter thanits road-going sibling; this translatesinto faster acceleration out of cornersand even more pronounced stoppingability. The thin seats, solid steeringwheel and solid pedals means that ev-ery message, no matter how subtle, istransmitted directly to the driver’sbody—minor nuances in the road sur-face can easily be felt.

However, these messages are of-ten overwhelmed by the violent airflowwhich absolutely bombards the driver.Helmet buffeting is considerably worsethan on a motorcycle, as is wind roar.This absolutely spoils the driving esca-pade at anything above about 50-60mph, and triple-digit speeds are virtu-ally impossible to bear.

Were this car to be equipped withtaller seats and at least a vestigialwindscreen, it could be an extremelyentertaining weekend play toy. In itscurrent configuration however, it’s adecidedly mixed driving experience,and it’s no wonder that relatively fewBarchettas have been sold.

Guará Barchetta—Performance Without Compromise

Pantera. A glance in the center rearview mirror reveals considerable distor-tion from the highly curved rear win-dow, but the two door-mounted mirrorsoffer an excellent view to the sides.

Due to the fundamentally tractablenature of a stock Ford V-8, the Guaráis perfectly comfortable amblingthrough Modena traffic, although theextreme width of the car (six feet, eightinches!) can be a bit intimidating onnarrow European city streets. Even inextensive stop-and-go traffic, the en-gine temperature never gets past thehalfway mark on the gauge, indicatingthat the cooling system is more than upto the task at hand.

Perhaps surprisingly for an Italiancar, the air conditioning system is fan-tastic. The controls are easy to usewithout looking at them, and the cabincan quickly be cooled to the point ofbeing uncomfortable even on an ex-tremely hot day. The electric windowsraise and lower quickly and quietly.

Leaving the city and climbing outof the valley on one of the myriad nar-row roads which surround Modenabrings the Guará into its element. Freefrom the constraints of traffic, it is freeto run with abandon, and indeed it does!

As a corner approaches, turn-in isreasonably crisp, and the traction pro-vided by the sticky Michelin tires seemsunending. Unfortunately, the Guará issaddled with a power-assisted steeringrack that delivers plenty of feel, but

quickly enough should the rear end sud-denly step out, and this effectivelyserves as an informal speed governorin the corners.

There is nothing preventing ridicu-lous speeds in the straight sections,however! The engine, by virtue of itsfour-valve design and relatively smalldisplacement, lacks the prodigioustorque commonly found in AmericanV-8 engines, although the torque is stillimpressive by European standards. Theengine is extremely willing to rev to-wards the stratosphere, and at higherRPM it is indeed quite rewarding. Duepartly to low gearing, and partly to lowweight (3086 lbs), the Guará absolutelylaunches out of corners. The exhausthowls pleasantly, and the gearbox shiftsextremely quickly and smoothly.

When a corner approaches, thebrakes do an absolutely spectacular jobof shedding excess speed. Brembobrakes are widely considered to be thebest in the world, and an aggressivedrive in the Guará quickly shows howthey have earned their reputation.

Over bumpy roads, the ride is firmbut well-damped; clearly somebody hasdone their homework in the chassis de-partment. Bump-steer seems nonexist-ent, and the car continues to tracksmoothly through corners even onrough, rutted roads.

If anything, the chassis is so com-petent that it sticks too well, making itvirtually impossible to discern its char-

acteristics at the limit on any publicroad. But it should go without sayingthat its combination of decent power,prodigious cornering grip andotherworldly brakes enable it to easilyleave any Pantera for dead on a twistyroad. It also feels quite stable and se-cure at speeds well over 100 mph, whilewind noise is pleasantly muted. Topspeed is listed as 168 mph.

The styling of the Guará has al-ways been criticized, and indeed eventhe most charitable will agree that itappears decidedly odd from someangles, although most agree that thenose is rather attractive. But fromwhere it counts—behind the wheel—the Guará really delivers the goods.The wealthy European driving enthu-siast desiring something a bit differentcan find in the Guará a very viable al-ternative to mass-market sports cars,one which will deliver genuine drivingexcitement at a competitive price.

Although the Guará has been ex-tensively (and expensively!) crash-tested and meets all current Europeanregulations, sadly it was never engi-neered to meet the more-stringent USAstandards, and thus it’s unlikely thatthey will ever be sold here (althoughSteve Wilkinson managed to get onelicensed for the street on amanufacturer’s plate, and Joe Mooreimported the very first Guará built as adedicated track car.)

But if nothing else, a drive in thewhose ratio isfar too slow, re-sulting in anundue amountof arm-twid-dling when theroad becomestwisty. Whilethe chassis iscapable of cor-nering so hardyour spleenwinds up on theother side of thecar, the slowsteering doesn’tinspire confi-dence. It wouldprobably be dif-ficult to react
