Ruf Automobile made its name building cars on unmarked Porsche chassis, so it's no surprise that their first car engineered and designed in-house bears more than a passing resemblance to a 911. The Ruf CTR Supercar is far more than a knockoff, however. It has the world's first rear-engine carbon fiber monocoque chassis, a 3.6L twin-turbo flat six engine producing 700 hp, a six-speed manual to help send that power to the rear wheels, and a carbon fiber body to help reduce weight. All of that combines in eye-popping performance, including a 0-60 time of 3.5 seconds and a top speed of over 220 mph. Built in Germany, production will be limited to just 30 units.
