When the Lotus was introduced in 1957, Colin Chapman couldn't have imagined that over 60 years later the Seven would still be in production and inspire a legion of similar sports cars. The ultimate expression of the humble Seven has to be the Donkervoort D8 GTO-JD70, a low-slung roadster in the Seven mold with enough carbon fiber to make an F1 car blush and supercar performance, built for founder Joop Donkervoort's 70th birthday. The D8 GTO-JD70 is powered by an Audi-sourced inline-five making 415 horsepower, enough to rocket the 1,500-pound road missile from 0-60 in 2.7 seconds and to a top speed of 174 MPH. But straight-line performance isn't what the JD70 really excels at — it's the corners. The JD70 can pull 2g's of lateral acceleration — for reference, an F1 car can make 4-6g while cornering. Only 70 units of the D8 GTO-JD70 will be made, each one built to the buyer's specification.
