http://autoweek.com/news.cms?newsId=101260 The second concept, for now dubbed Firepower (Chrysler does not own the name and will need a new one prior to Detroit), is based on the V10 Viper’s architecture but uses the 6.1-liter, 425 hp, 420-lb-ft Hemi V8 that will see first light in the forthcoming 300C SRT-8. Again, officials say there are no production plans, but envision the car occupying the space between the Crossfire and (in theory) the ME412 in Chrysler’s performance portfolio. Though the car is Viper-based—and Creed referenced Chevrolet’s Corvette as a key competitor (again, in theory)—the designers envision “Firepower” as more grand tourer than outright sports car; hence the softened suspension and five-speed automatic transmission. Brakes are 14-inch Brembos at all four corners, and the huge rubber measures 275/35 R19 up front, 335/30 R20 in back. Engineers estimate the car is capable of bolting from 0 to 60 mph in 4.5 seconds or less, and a 185 mph top speed. Whether either car ever meets a production line, Chrysler has produced two concepts that would fill obvious holes in both Jeep’s and its own product lineup; executives will keep careful watch on public reaction at Detroit in January.
