It might be hard to imagine making 20 different versions of the same car, but Porsche has managed it with its 911. Two of them are the hard-top and soft-top versions of the 2011 Carrera GTS. It has the same broader-around-the-beam body as the Turbo to accommodate a wider rear track than the usual Carrera. Which makes it better to slam down 408 hp onto the road, making this the most powerful 911 before we get into harder-core GT3 territory. With the six-speed, two-pedal PDK transmission and the Sport Chrono Plus package, the sprint from standstill to 60 mph happens in four seconds flat. The tin-top starts at $103,100 and the cabrio starts at $112,900. Those prices include the body kit and cool black wheels.
