Creating a vision

More and more politicians and environmental organizations seem to increasingly hate the Sport Utility Vehicle (SUV), in The Netherlands also known as PC Hooft-tractor. After efforts of Amsterdam and Nijmegen to keep the big cross-country vehicles out of their city, London also decided to refuse the SUV’s. To be honest it seem quite logical to refuse those SUV’s. Their heavy weight and probably not optimal aerodynamics causes high fuel consumption and emissions and in most of the time these 5/6 persons vehicles are driven by 1 person and sometimes by 2.Therefore it is necessary for SUV-manufactures to think about possibilities to keep on growing and stay a healthy brand. One of those possibilities is to open a new niche, namely the SUV-coupé. The Hybrid SUV-coupé is a hybrid cross-country vehicle which has to occur as a sporty coupé. A ‘normal’ SUV has already a slightly sporty appearance. The SUV-coupé on the contrary has to have a more sporty appearance than his bigger brother, but still has to have the visual presence - large vehicle - of his bigger brother. Most drivers of normal, larger SUV’s never use the third and fourth door - two side doors at the back. For this kind of user the hybrid SUV coupé is the ultimate solution. Niche examples are: Land Rover LRX Concept, BMW X6, Ssangyong Actyon, Citroën Hypnos, Audi Q3, Mercedes BLK, Mitsubishi Nessie.

This small hybrid SUV Coupé is powered by a hybrid engine. The vehicle has to have the sporty appearance of a coupé vehicle and the visual presence and power of a SUV. The vehicle is appropriate for two persons and has three doors (two doors and one trunk door). Furthermore the vehicle has a design to appeal in the luxury and executive sector and has to show the status of the owner and/or driver. Finally luggage space and easy loading and unloading of luggage is very important.

The target group of this new SUV-coupé could be the people I mentioned before, namely the ones which are normally travelling alone in the larger SUV’s and never use the fourth and fifth door. To get more focus on rituals and habitats of the intended users I decided to focus on persons which has and want to spent money on a vehicle, but also on their daily life, such as shopping. Therefore loading and unloading their shopping might be a very important factor in this new SUV-coupé.

For this SUV-coupé I would like to focus on a hybrid technology such as used in the Citroën Hypnos. Specifications of this hybrid technology are: a 200HP motor, a fuel consumption of 4,5L/100km and an emission of 120g/km CO2.

Rough clayClay modeling

In order to convert the 2D sketches into a 3D model, rough clay models were made. On the following pages the different variations are figured.

Clay modeling

After converting the sketches into 3D clay models, photos were taken. These photos were imported in Painter and using a computer sketch-tablet, new 2D sketches were made. On this page, different sketches of the side view are figured. Finally one sketch was chosen (red square).

Clay modeling

With help of the clay model based sketches, more de-tailed sketches were made. These sketches are shown on this page.

Clay modeling

Again rough clay were used to transform 2D sketches into a more understandable 3D shape. On this page photos of this last rough clay model are shown. As seen on the photos, the clay model was only modeled at one side of it. Using Photoshop the photos could be mirrored and this resulted in the pictures as shown on this page.

CAD modeling

From the clay model as shown on the previous page, blue-prints could be made. These blue-prints were used to model a 3D CAD model. Software used to create this 3D model was Rhinoceros. The reason for 3D CAD modeling the SUV was simplifying the process of automotive clay modeling. Right measurements and symmetry are difficult factors when creating such a large model.Later on Bunkspeed’s Hypershot was used to render some presentation pictures. These pictures are shown later on in this report.

StartingFinal model

After creating the section contours, a foam model was made. By using the section contours the foam model could be created as exact as possible. Some space around the foam model was needed for the automotive clay. Hereafter the automotive clay could be placed roughly, followed by smoothing the clay.

FinishingFinal model

After many hours of work the clay model could finally be finished. The wheels are created with a small foam milling machine and the rims are created out of aluminium using a CNC milling machine.

Conclusion

This course was the most interesting course I did during my Master specialization. From creating an idea about a possible vehicle for a specified user group, to converting a 2D sketch into a 3D model, everything done in this course was with great enthusiasm. For everyone who has the time (important factor actually) I recommend to do this course. The only disadvantageous I noticed were the big spends for all used material, especially the automotive clay.

Unfortunately I did not get any message about a exposition with all Automotive Design 3D models. On the day itself I heard about the exposition, by then it was already too late. Next time, more luck I guess.

In spite of this missing exposition it was a great adventure and a fantastic experience!
