The light runner


The experts at ELASTOGRAN were consulted in order to implement the carbon fibre-reinforced PU component to turn the Geneva motor show 2007 prototype of the Artega into a motor-racing approved sports car, for everyday use.


With 300 HP under an ultra-light PU body, the new Artega GT sets the standards in weight, acceleration and particularly in consumption

Excellent design, high performance — with the arrival of the Artega® GT, a true highlight of the sports car scene slips into the fast lane. The breathtakingly styled coupé is enhanced with a unique synthesis of performance development, consumption, operating range and travel efficiency; a podium finish in the 300-HP league. But that's not all. As a worldwide first series vehicle, the Artega has a body made completely from PU — giving it a consistent focus on lightweight construction.


Flashback: Geneva motor show 2007. The prototype of the Artega celebrates a brilliant premiere. The professional world and visitors alike are enthralled by the new German sports car, weighing just 1,100 kg and, with a power/ weight ratio of 3.72kg/HP, setting new standards in its class. The Artega now has exactly what the prototype of the Gran Turismo embodied in the 1960s: concise dimensions, ample room for the journey, a sporty engine and, because of its lightweight construction, a high degree of agility. Although it is not a "super" sports car, its values in driving dynamics mean, it can easily take them on and go even further with its captivating qualities in long-distance performance and everyday use. In short: It promises driving pleasure of the highest degree.

300 horses underneath, a layer of PU on top — that's how you achieve 0 to 100 in 4.8 seconds


Apart from the 300-HP-V6 engine and the elegant, comfortable direct shift gearbox (both from Volkswagen), everything in the Artega is new. The goal of the sports-car-smiths at Artega, in the Westphalian town of Delbruück, was to develop a sporty vehicle that's also suited to everyday use, with well-engineered, high-volume components. The experts at ELASTOGRAN were consulted in order to implement the carbon fibre-reinforced PU component in the motor-racingapproved material combination of aluminium and highstrength steel. Working in close cooperation, the polyurethane lightweight construction body was developed, which today is made by experienced customers and partners, such as Erwin Friedmann Kunststoffwerk GmbH, Offenburg, and Automobilund Kunststofftechnik GmbH, Hörselberg.


The combination of various polyurethane materials with outstanding mechanical properties makes the sleek two-seater genuinely lightweight and offers the additional advantages of cost and safety. Wings, tailgate, front and side parts of the sports car consist of Elastolit®, the carbon fibre-reinforced, microcellular PU system, which is characterised by a high degree of robustness and good impact strength even in extremely cold temperatures.


So light — so good. Using Elastolit, car body components of enormous accuracy are achieved that are resistant to deformation


Using Elastolit as part of RIM-technology (Reaction Injection Moulding) has been proven to allow the construction of parts that have a distinctive, inherent rigidity and a narrow wall thickness. The low thermal coefficient of expansion of the fibre-reinforced polyurethane system provides for a high fitting accuracy and an extreme thermostability of the construction components. Due to its high surface quality, the lightweight construction material is ideally suited to the Class-A-lacquer finish of visible free-formed surfaces. In the roof, boot and bonnet, special polyurethane material combinations with sandwich constructions are used, which are characterised by aneven higher degree of torsional rigidity with a light weight. All these advantages, which are also present in the back-foamed bonnet, are possible thanks to the polyurethane compound structure.


Injected for one second, hardening over 15 to 30 seconds — finished. This even applies to highly complicated, filigree construction units


Many of the polyurethane body parts used in the Artega are manufactured using RIM procedures. The two-component, liquid, fibre-filled and highly reactive polyurethane system Elastolit is injected in one second into a closed tool. After just 15 to 30 seconds the finished construction unit can be removed from the mould, maintaining its high quality. In contrast to conventional injection moulding procedures, the PU RIM materials are fluid during the reaction and possess outstanding flowability properties. These are essential conditions for the realisation of complicated construction unit geometry and filigree design standards.


Pure sports car driving pleasure without purist ambience. Even in this dimension the new Artega GT is in a class of its own


The lesson is clear: The Artega is a "pure" sports car, without being purist. The subject in question is the beginning of a new car brand, creating something totally new without the constraints of the past. In all areas, the Artega is aligned with the established processes of mass production. Apart from the extraordinary development costs, this claim is especially apparent in the construction of the new 6,000 sq m car factory in the Westphalian town of Delbruück, where, for example, industrial processes in low volume production are carried out. Artega deliberately does not work in the sense of manufacturing according to the workshop principle, but rather in line manufacturing similar to mass production.


Just one more thing to say: The facts are clear — get in the Artega, start it and drive off — because every yard you cover will be much more convincing than anything else we could say.
