The Porsche 959 couldn't have been more German. It was ridiculously advanced for its time with features that today are often times standard. But it was insanely fast thanks to its 2.9-liter twin-turbocharged flat-six that produced 444 horsepower, helping it hit a top speed of 197 mph. It even had all-wheel-drive, something new for Porsche at the time. There was nothing else quite like it when it debuted in 1986 and was the fastest production car in the world. But in 1987, the Ferrari F40 came along.

With a top speed of 201 mph, the F40 was the last Ferrari built under the supervision of Enzo Ferrari. Its power came from a 2.9-liter twin-turbo V8 with an output of 471 horsepower. Both cars are incredible and while one may be a bit faster than the other, it's really hard to say which is better. It all comes down to personal opinion and whether you're a lover of Porsches or Ferraris. Regardless, the 959 and the F40 are perhaps two of the greatest supercars to have ever been made.
