2007 to 2009
Body versions :
The Opel GT was introduced in March 2006 as the successor to the Opel Speedster at the Geneva Motor Show and was voted Convertible of the Year 2007 by an independent expert jury .The GT is based on the platform of front engine, rear drive of the Opel parent company GM , on which also build the nearly identical Saturn Sky , Pontiac Solstice and Daewoo G2X . These vehicles and the Opel GT were built in Wilmington, Delaware . The Design Director of General Motors, Franz von Holzhausen, is responsible for the design of the Kappa platform .
The model has a 9.2: 1 compressed 2.0 liter turbo Ecotec four-cylinder engine (Z20NHH, LNF) with a power of 194 kW (264 hp) at 5300 rpm, gasoline direct injection , double variable camshaft phasing and dual-flow turbocharger with intercooler . The engine is derived from the 2.2-liter engine already known from the Astra , Vectra and Signum . Later, the modified engine with the engine codes A20NHT and A20NFT was also used in the Opel Insignia with an output of 162 to 184 kW (350 and 400 Nm) and in the Astra J OPC with 206 kW and 400 Nm.The maximum torque of 353 Nm is at 2000 / min, according to factory specifications, the GT accelerates from 0 to 100 km / h in 5.7 seconds, the top speed is 229 km / h with an average consumption of 9.2 l / 100 km , The figure of 5.7 seconds per 100 km / h was extrapolated on the basis of the American value (0-60 mph ); 60 mph, however, correspond to only 96 km / h and not 100 km / h. After being measured by Autobild Sportscars , the Opel GT accelerates to 100 km / h in 6.3 seconds.
The Opel GT is 4100 mm long, 1813 mm wide, 1274 mm high and has 2415 mm wheelbase. The empty weight is up to 1406 kg, however, significantly higher than the Speedster Turbo (930 kg tare weight). The standard equipment includes a manual soft top, manual air conditioning , a manual 5-speed gearbox and a limited slip differential with up to 70% blocking.The wheels are suspended on double aluminum wishbones on both axles. The front-rear weight distribution is almost optimally balanced at 51: 49.The driving behavior is monitored by the four-stage electronic stability program ( ESP ), in Opel: ESC (Electronic Stability Control) in the following modes are selectable:Normal, without display (ESP on, traction control , in Opel: traction control on),ASR off (ESP on, traction control off),Sport mode (ESP intervenes later and allows for larger drift angle, traction control) andESC off / ASR off (ESP off, traction control off). Another feature of the chassis is a torsion support between the transmission and rear axle, which absorbs load change reactions during acceleration and braking.
The fabric hood can only be operated manually. After the electric release of the fins and the top cover, the roof can be unlocked manually and folded up. For stowage, the driver must leave the vehicle, manually open the unlocked convertible top lid, lower the roof in the roof space and close the convertible top flap again. When closing two additional fins must be manually folded down and locked in openings of the convertible top lid.With no significant trunk is not available, so the vehicle is designed solely for driving pleasure and in no way on everyday practicality.The Opel GT was available in the colors onyx black, midnight blue, solar yellow, metal gray, damask silver, granite gray, Eifel blue and Victorian red. A "premium package" (partial leather interior of the seats in ebony or kobal red / ebony black, made of PVC: seat backs, headrests and door panels, and CD changer )
