Excessively long at the prow and slinky low for a two-seat cockpit with a raucous ten-cylinder engine exerting overwhelming muscle from a herd of horses, the SRT10 Viper from Dodge is America's most powerful sports car. It delivers 500 hp with 525 lb-ft of torque out of 505 cubic inches in engine displacement.

For 2006 the roadster convertible version is joined by a new coupe edition sporting a double-bubble roofline, door window glass, special wrap-around taillamps and a body color scheme in Viper Blue with Stone White race stripes.

A heavy-duty six-speed manual transmission is standard for both the coupe and roadster, along with aluminum components for the four-wheel independent suspension plus huge Brembo disc brakes tied to a four-wheel anti-lock brake system (ABS). Wheels -- 18-inch up front and 19-inch in the rear -- support Michelin zero-pressure run-flat tires.
