2006 TechArt Cayman GTsport
3.8-liter displacement, 385 hp, 407 Nm and a top speed of 285 km/h: Those are the performance cornerstones of the new TechArt GTsport, that TechArt Automobildesign builds in small-series production based on the Porsche Cayman S.
At the heart of this mid-engine sports car lies the increase in displacement from standard 3,387 cm³ to 3824 cc. The increase is facilitated by a bore enlarged to 99 millimeters with the corresponding larger special pistons, and by the installation of a special crankshaft.
The engine conversion further includes sports camshafts. A modified intake manifold with special air filter system and an aluminum header provide ample combustion air. The perfect interaction of all these components including the fully stainless-steel high-performance exhaust system with high-performance manifold is orchestrated by new mapping for the engine electronics.
With a maximum power output of 385 hp / 283 kW and a peak torque of 407 Nm the TechArt displacement engine satisfies both highly sporty minded drivers as well as those GTsport pilots who want lots of pulling power from low engine speed. Powered by this engine, the mid-engine sports car offers excellent performance: The sprint form 0 – 100 km/h takes just 4.9 seconds, and with a top speed of 285 km/h the TechArt two-seater easily bests its production counterpart in this discipline, too.
The exhilarating performance is coupled with striking looks and refined aerodynamic properties. The TechArt GTsport front apron is designed to replace the production bumper. With its large air inlets and four auxiliary headlights it lends the two-seater a more dynamic appearance while reducing lift on the front axle at high speeds. The extendable carbon air splitter can further minimize aerodynamic lift.
The TechArt rocker panels were modeled to calm the airstream between front and rear wheel houses. They also give the two-seater a longer, sleeker appearance. Carbon mirror moldings round out the racing look of the TechArt GTsport.
To optimize downforce on the rear axle and for even more striking looks TechArt Automobildesign further equips the GTsport with a rear wing with extendable carbon gurney flap. The rear apron is refined by a carbon diffuser.
Striking looks and agile handling are the hallmarks of the TechArt tire/wheel combination on the GTsport. The especially light-weight one-piece TechArt Formula five-spoke wheels are mounted on the front axle in size 8.5Jx20 with ContiSportContact 3 tires in size 235/30 ZR 20. The rear axle features wheels in size 11Jx20 with size 305/25 ZR 20 tires.
Specially calibrated to these wheels and tires is the TechArt VarioPlus coil-over suspension for all vehicles that are factory-equipped with the electronically adjustable PASM damper system. This suspension not only allows adjustable ride-height lowering by up to 25 millimeters, but also manual selection of damper settings Normal and Sport at the push of a button in the cockpit. The dampers are not limited by the manually selected setting: Sporty driving automatically firms up the dampers in both suspension modes. The result is an optimal symbiosis of excellent ride comfort during normal driving and agile direct response during fast cornering.
As a world-renowned specialist for exclusive car interiors TechArt Automobildesign will customize the interior of the GTsport in the company-own upholstery shop according to customers’ individual specifications.
The product lineup includes exclusive fully leather interiors as well a numerous sporty accessories: TechArt offers ergonomically shaped airbag sport steering wheels with three or four spokes as well as aluminum foot pedals, shifter and foot rest. Also available are stainless-steel door sills with TechArt logo.
