And you thought the Cadillac CTS-V was fast. The 2013 Hennessey VR1200 Twin Turbo ($TBA) is based on Caddy's sporty coupe, but bests it in the performance department thanks to a twin-turbo 7.0L V8 pumping out 1,066 rear wheel hp — allowing it to rocket from 0-60 mph in just 2.9 seconds on its way to a top speed of 242 mph. Upgrades are also made to the camshaft, fuel system and injectors, brakes, wheels and tires, suspension, sway bars, and interior. Of course, no high-end sports car would be complete without some carbon fiber, which you'll now find on the front splitter, rear diffuser, front fenders, hood, and rear flares.
Think you can't drive a Porsche in bad weather? Think again. The 2013 Porsche 911 Carrera 4 ($91,000-$118,000) sports the active all-wheel drive Porsche Traction Management system to ensure you can get where you need to go even when the conditions are less than perfect. Other features include a standard 7-speed manual gearbox, an optional 7-speed dual-clutch PDK automatic transmission, 350 hp for the standard model and 400 hp for the 4S, optional Adaptive Cruise Control, and either a Coupe or open-topped Cabriolet body.
