Hennessey has already created what was once the fastest Nissan GT-R in the world, but not everyone can handle 800 kicking horses in one sports car. So, for those with not enough gusto to handle the beast, but who are not satisfied with the tame 473 HP found in the standard GT-R->ke1592, Hennessey has a package for you. It is called the GTR650, and the name pretty much says it all.

Thanks to a new stainless steel mid pipe exhaust, a new induction system, a modified boost controller, and new intercoolers, the 3.8 liter twin-turbo V6 engine delivers an impressive 662 HP at 6,500 rpm and a peak torque of 638 lb-ft Torque at 4,100 rpm. Unfortunately, there was no mention as to how this boost affected the performance of the sports car, but we are going to state the obvious when we say it will probably be faster than the standard, but slower than the 800hp modded GT-R. Next to the engine upgrade, Hennessey->ke1863 is also offering a transmission clutch pack upgrade.

In order to handle this amount of power, the GTR650 package needed to include new, improved suspensions and new sport brakes. A few different carbon fiber aerodynamic components, a new set of wheels, and performance tires were also added to complete the look and feel of the Nissan->ke62 GT-R.
