In 1937, Auto Union (now known as Audi) developed a racing vehicle known as the Auto Union Type C Streamliner, meant to break records at the AVUS race track, which had straights over five miles long. It looked nothing like the other cars of the field, and was capable of 248 miles per hour. The car unfortunately crashed, and further development was halted due to the outbreak of World War II.
This 1967 model is designed with performance that surpasses the original. It has a 6.1-liter supercharged V12, producing upwards of 1,000 horsepower, weighs just 2700lb, and is capable of an insane top speed of 250 miles per hour.
Be careful, though; being from 1967, it has absolutely zero downforce (actually, some lift); it will wheelspin 4th gear and handling it around a corner is an absolute chore, but can be done with excellent agility if you're a good driver.

How does it feel to do 250 mph in a supercharged racecar from before downforce was invented?
