The Dodge Viper is a two-seat sports car, the most powerful production car made by Dodge. The Viper was conceived as a modern take on the classic American muscle car.
The first generation (92-95) The centerpiece of the car was its engine. Originally designed as a truck engine and based on the Chrysler LA engine, Lamborghini, then a division of the
Chrysler Corporation, revamped Dodge's cast-iron block V10 for the Viper by recasting the block and head in aluminum alloy, and giving the engine a significant power boost.
The engine produced 400 hp at 4600 rpm and 450 ft·lbf of torque at 3600 rpm, and thanks to the long-gearing allowed by the torquey engine, provided surprising fuel economy at a claimed 21 mpg
Second generation models increased engine power, improved suspension, and reduced braking distances; the 1996 to 2002 Viper GTS had a 450 hp engine, which could complete the quarter mile 0.7 seconds faster and increased top speed by 22 mph or so.
The Dodge Viper underwent a major redesign in 2003, courtesy of DaimlerChrysler's Street and Racing Technology (SRT) group. The new Viper SRT-10 was heavily restyled with sharp, angled bodywork. The engine was enlarged to 8.3 L which, with other upgrades, combined to increased output to 504 hp and 525 ft·lbf of torque.
Viper GTS-R - Using such production engine components as the block, cylinder heads, and crankshaft, Team Viper engineers were able to extract 700 hp from the normally 450 hp second generation 8.0 L V10 engine.
