Dodge Viper 2002 to 2010
Third Generation SRT-10 2002-2006
The new 2002 Viper SRT-10 is given a new look with sharper lines with the same engine but bored to 505 cu in (8.3 L) it now produces 500 bhp (370 kW) and the motor weights 500 lbs (230 kg) less. The stronger redesigned chassis also weights 80 lbs (36 kg) than the earlier model. Initially the Hennessey Viper Venom 1000 Twin Turbo model it introduced as a convertible only. The SRT model has a limited edition with only 200 units called the “Mamba” option package available in 2004 which features a black interior with red stitching. There is a Viper SRT-10 Coupe for 2006 and is shown at the Detroit auto show in 2005 with many of the same body panels as the convertible but the sides and rear are similar to the earlier coupe as well as retaining the double bubble roof.
The paint is blue with white stripes; reminiscent of the original Viper coupe but the engine puts out 510 bhp (380 kW) now. The coupe is heavier than the convertible and slightly slower but the stiffer frame with reduced drag improve handling, particularly at high speeds, is better than the convertible. The coupe does the quarter in 11.77 seconds reaching 123.68 mph (199.04 km/h) and does 0-60 (97 km/h) in 3.8 seconds. The 2006 models are offered through 2007 as Dodge prepares for the release of the new 2008 Viper.
Fourth generation Phase II ZB – 2008-2010
The 2008 Viper now has a 510 cu in (8.4 L) V10 producing 600 bhp (450 kW) at 6,000 rpm featuring large flow heads, larger valves, and variable valve timing on the exhaust cam lobes with two electronic throttle bodies. With the electrical system also revised and a new 180 amp alternator and twin electric cooling fans are also installed. This engine has improved valve train stability, with new camshaft profiles and valve springs it idles 300 rpm quicker than its predecessors. Earlier models have a crossover exhaust under the driving compartment –these pipes are revised which considerably reduces the heat rising in the cockpit. The Tremec T56 transmission is replaced with the new Tremec TR6060 and the Dana rear axles are now the Dana GKN and turned by the Viscolok speed-sensing differential which helps the Michelin “Pilot Sport 2” tires get a grip. The springs are upgraded as well with the result of the car handling better – particularly in corners.
This Viper does 0-60 in 3.5 seconds and the quarter in 11.5 seconds reaching 126 mph (203km/h) coupled with better driver control it beats out the competition –both domestic and the imports at Virginia International Raceway. The final edition of the Viper SRT10 in convertible and coupe models are made available with only 50 units offered.
The new Viper is not available in 2011 but the 2012 Viper prototype is unveiled at two auto shows throughout 2011 it has a very long hood with the passenger compartment far back giving hints of what is to come. The new Viper will be all new not based on anything past it will have stability, handling, with performance and it will appeal to a wider range of consumers.
