The Dodge Viper SRT10 Coupe’s hardtop with its “double bubble” styling makes it even more torsionally stiff than the Roadster. The 2009 Dodge Viper SRT10 Coupe offers increased downforce and high-speed stability with its sloping roofline and deck lid spoiler. Plus, the Dodge Viper SRT10 Coupe has an additional 6.25 cubic feet of trunk space than the Viper SRT10 Roadster, for a total of 14.65 cubic feet. The roof and headliner structure offer more room to accommodate a safety cage, while maintaining as much head room as possible.

The 2009 Dodge Viper SRT10 Roadster and Coupe cockpit retains its characteristic red push-button starter and performance-oriented, highly functional instrument panel with center-mounted tachometer and 220-mph speedometer.

Five interior colors will be available in 2009: black, black/red, black/blue, black/medium slate or black/natural tan. A choice of bezel finishes on the center instrument panel and console adds to the increased level of customization.

ENGINEERING

The 2009 Dodge Viper SRT10’s deep-skirted V-10 aluminum block features 8.4 liters (510 cubic inches) and generates 600 horsepower and 560 lb.-ft. of torque. And all the power is compliant with stringent regulatory requirements, such as federal Tier 2, Bin 5 and California’s Low Emission Vehicle (LEV II) mandates.

The 2009 Viper SRT10 engine features cylinder heads equipped with Computer Numerically Controlled (CNC)-shaped combustion chambers, larger valves and Variable Valve Timing (VVT) featuring award-winning CamInCam® technology. The VVT application used in the 2009 Dodge Viper SRT10 electronically adjusts when the exhaust valves are opened and closed according to engine speed and load, allowing the engine to “breathe” more cleanly and efficiently.

The 2009 Dodge Viper SRT10 V-10’s two-piece intake manifold combines a cast-aluminum lower plenum with smooth runners for better air flow, bolted to a die-cast aluminum upper plenum. The air-cleaner box with a low-restriction filter sends air through dual electronic throttle control modules into the intake plenum.

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. Within the cylinders, pistons are equipped with large-diameter floating pins in bronze bushed rods for high-load capability. The forged powder-metal connecting rods are secured with aircraft-quality fasteners for increased fatigue strength.
