This combination of a Lotus Elise chassis and 1,244-hp 7.0-liter twin-turbocharged V8, and you have the fastest production car in the world. Depending on your definition of “fastest” and “production car,” that is.

Hennessey recorded a 270.4-mph run at the Kennedy Space Center last year, but only in one direction. To be considered legitimate, record attempts usually require one run in each direction. An average is then taken to account for wind conditions.

Because of its hand-built nature, there’s also some debate about whether the Venom GT qualifies as a production car. While it can claim the highest recorded speed, Hennessey’s monster isn’t recognized as the world’s fastest car by the Guinness Book of World Records.
