Aerosmith frontman Steven Tyler just took delivery of the world's fastest convertible. The Hennessey Venom GT Spyder will accelerate to 200mph in 15.9 seconds, eight seconds faster than a Bugatti Veyron. Tyler was the first person to ask if he could have his without a top.

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

Only five Venom GTs will be built this year and Tyler's remains the only convertible. At a price of $1.1 million for the Lotus Exige chassis lengthened and braced to make room for a 7.0-liter, twin-turbo V8, it's easy to understand why interested customers are few and far between.

When Matt rode in a prototype a year ago, he described the hand-built supercar as, "the best way to die."
