The Crossfire is a sporty "boattail" coupe concept from Chrysler. The driveable prototype is motivated by a supercharged version of the 2.7L V-6 (est. 275-bhp/270 lb.-ft) driving the rear wheels. A one-piece carbon fiber body is mated to an aluminum frame. 19" front wheels carry P255/40R19 tires. The 21" rear wheels are shod with P295/35R21 tires. Chrysler estimates 0-60 mph in 5.8 seconds for the 5-speed manual equipped Crossfire; and a top speed of 148 mph.
