The Dodge Ram SRT-10 was introduced February 13, 2003 but not put into production until 2004. Unlike the previous Ram Trucks, the SRT-10 was built solely for the purpose of speed. In fact, in February, 2004 it set both the Guinness World Record and Sports Car Club of America's record for fastest truck. The previous record holder, the Ford Lightning, attained a speed of 147.54 mph, while The SRT-10 reached a high speed of 154.59 mph.
The main attraction of the SRT-10 is its engine, which is an 8.3 Liter V10 Viper Engine. This engine produces 500 horsepower at 5,600 rpm and 525 lb-ft of torque at 4,200 rpm. With this engine the truck can reach a top speed of 154 mph, and can accelerate the regular cab SRT-10 from 0 to 60 in 4.9 seconds and the Quad Cab version in 5.4 seconds. The stock 22 inch rims and Pirelli Scorpion P305/40R22 performance tires gives the SRT-10 the grip that helps it achieve record breaking speed. The SRT-10 comes with either a TREMEC 6 speed manual transmission (regular cab) or a 4 speed automatic transmission (Quad Cab).
Dodge Viper SRT 10:
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 (375 kW) and 525 ft·lbf (711 N·m) of torque. The initial model was a convertible.
The new Viper SRT-10 Coupe (no longer called the GTS) was introduced in 2005 at the Detroit Auto Show as a 2006 model. It shares many of its body panels with the convertible but takes its side and rear styling cues from the Competition Coupe (see below). The new coupe looks much like the previous Viper GTS and retains the "double-bubble" roof shape of the original, along with the original GTS's taillights, for an added homage to the original Viper coupe. In addition to these style upgrades, the Viper receives 510 hp (380 kW) and 525 ft·lbf (711 N·m) of torque.
