The Hennessey Venom GT is unofficially the fastest car in the world after it set a top speed of 270.49mph (435.31 km/h). That would make any car enthusiast in the world happy, apart from John Hennessey himself. Why? Because he wants the car to go faster!
To go faster, Hennessey will upgrade the Venom GT's power from 1,244bhp to 1,451bhp, and showcase the car at the Specialty Equipment Market Association (SEMA), which is due to take place from November 3 to November 6, 2015.
Hennessey claims that 207bhp increase to the present engine should help the car reach a theoretical top speed of 280mph (450.61km/h). The power will be extracted from the same 7.0-litre, twin turbocharged V8 engine sourced from General Motors.
The engine will be able to run on E85 ethanol, which allows the tuning company to increase the car's boost pressure from 19 psi to 26 psi. That's not all; the Texas-based tuning company will also bring a convertible Mustang that has 774bhp under its hood and a Ford VelociRaptor that packs 650bhp.
