HENNESSEY VENOM GT1 and 244HP

The Hennessey Venom GT is effectively a 1,244hp Lotus Exige S2 and that car was quick with a measly 190hp. Ok, so it s stretched a bit over the Norfolk track special to house the massive 7.0 litre twin turbo V8, but the chassis is very similar. The low kerb weight of just 1,244kg (that s 1hp per kilo, incredibly) helped it set the World Record for the fastest production car ever at 270.49mph. And Hennessey says it can go even quicker
