Featured car history
Dodge Viper 2008
In 2008, with the introduction of the 8.4 L V10, the Viper produced 600 hp (450 kW) at 6000 rpm and 760 N⋅m at 4600 rpm, and also received better flowing heads with larger valves, Mechadyne cam-in-cam variable valve timing on the exhaust cam lobes, and dual electronic throttle bodies. The rev limit could be increased by 300 rpm due to the improved valve-train stability from both the new camshaft profiles and valve-springs. The engine was developed with some external assistance from McLaren Automotive and Ricardo Consulting Engineers. Electronic engine control is developed by Continental AG; the controller can monitor the crankshaft and cylinder position up to six times during each firing and has 10 times more processing power than the previous unit. Changes outside of the engine were less extreme, but with a distinction between the third and fourth generation, with changes of the engine hood.
