Not to be confused with the popular drink, Hennessey Performace, a tuning firm, set out to make the normaly bulky Cadilac CTS-V Coupe faster and less heavy. Hennessey will be using a twin-turbocharged 427ci LS V8 engine that has an output of 1000hp at 6.400rpm, allowing the vehicle to accelerate from zero to 60mph in 3.5 seconds and reach a top speed of 230mph (370km/h). Making the load lighter, Hennessey also built a widebody kit using carbon fiber that’s expected to lose  the weight of the Cadillac V Coupe by 200 lbs (about 90 kg). Anyone who drives this baby is in for the ride of their life.
