Because it is street legal, die-hard Viper and track enthusiasts can drive their car to the race track, run it at speed on the track, and then drive it home. "With the Viper SRT10 as the starting point, SRT engineered a combination of reduced weight, race tuned suspension and aerodynamic improvements to create the ultimate Viper for the street and track," said Mike Accavitti, Director - Dodge Brand and SRT Marketing and Communications, Chrysler LLC. Derived from the 2008 Dodge Viper SRT10, the heart and soul of the Viper SRT10 ACR is SRT's new 8.4-litre aluminium V10 engine that produces 450kW and 760Nm of torque. The 2008 Dodge Viper SRT10 ACR stays true to the five key aspects of SRT: standout powertrain, bold exterior styling, race inspired interior, benchmark braking, and world class ride and handling characteristics across a dynamic range.
Exterior styling cues offer not only bold aesthetics but functional benefits on the track. These include a variable geometry "fanged" front splitter, an adjust-able rear wing and optimised front dive planes. These new aerodynamic devices are formed in high performance autoclaved carbon fibre. The front splitter includes three removable rub strips that provide protection and wear resistance. Supported by stainless steel tension cables, the splitter is designed to absorb the energy from minor upward deflections. The Viper SRT10 ACR goes a step further to satisfy what racers want: the least weight possible. An optional "Hard Core" package offers maximum weight savings by deleting the audio system, under hood silencer pad, rear cargo carpet and tyre inflator. The ACR suspension includes coil-over racing dampers from KW Suspensions that are adjust-able for damping and ride height.
The shocks are two-way adjust-able without removing the wheels - a time saver on the track - and they include a large range for compression and rebound. The SRT10 ACR sports the latest evolution of the Tremec T56 six-speed manual transmission known as the TR6060. Power is transmitted to the rear wheels via a GKN ViscoLok speed sensing limited-slip differential. The 2008 Viper SRT10 ACR features a signature two-tone paint scheme with a black centre section. An optional driver's stripe is available on a two-tone Viper Red or a Viper Black ACR. It has a RRP of less than $100,000 (US).
The Dodge Viper SRT10 ACR is powered by a new 8.4-litre V10 engine that produces 450kW of power and tyre smoking 760Nm of torque. It features a deep skirted V10 aluminium engine block, cylinder heads equipped with Computer Numerically Controlled shaped combustion chambers, large valves and Variable Valve Timing. VVT electronically adjusts when the exhaust valves are open and closed according to engine speed and load, allowing the engine to "breathe" cleaner and more efficiently. The two piece intake manifold combines cast aluminium lower with smooth runners for better air flow, bolted to a die-cast aluminium upper plenum. A revised air cleaner box with a low restriction filter sends air through a dual electronic throttle control into the intake module. The air-fuel mixture in the cylinders is ignited by platinum-tip spark plugs fired by individual plug coils mounted on the cylinder-head covers.
