Steven Tyler Car Shows His $1.1M World’s Fastest Car Hennessey Venom GT Spyder in Hollywood [VIDEO]

Aerosmith frontman Steven Tyler showed off his $1.1 million car.

The rocker was seen his hand-built convertible purchased last year this weekend after performing at the Stuart House benefit at John Varvatos in West Hollywood.

The Hennessey Venom GT Spyder was one of only five 2013 models, world's fastest street legal convertible. It can hit 200 mph in under 16 seconds. However it's reported his car is the only one built as a convertible.

"Steven came to us last year and asked if we could build his Venom GT as a roadster. We had to make a few structural changes to our integrated rollcage in order to be able to fit the removable top," John Hennessey told Yahoo Auto.

"This increased the weight of our vehicle by about 30 lbs to a curb weight of 2743 lbs (1244 kilograms). We decided to increase the Venom GTs power to 1244 bhp to maintain our 1 horsepower per 1 kilogram power to weight ratio," John adds.
