Dodge's high-performance 2-seat sports car revives its coupe body style for 2006. Viper now comes as a convertible with a manual-folding top and heated glass rear window, or as a coupe, which was last offered in 2002. The only engine is a 510-hp 8.3-liter V10. The sole transmission is a 6-speed manual. ABS is standard. Tires are run-flats on 18-inch front wheels and 19-inch rears. Side airbags and antiskid/traction-control systems are unavailable. Standard features include leather-and-faux-suede seats, tilt steering column, power-adjustable pedals, and xenon headlights. Dodge says it will offer satellite radio later in the model year.
