Although famously known in tuning muscle cars like the Camaro and turning it into a tire-shredding monster, Hennessey Performance Engineering also tinkers around machines from Europe like Ferrari and BMW. And the latest European machine to have gone under their knife is Jaguar’s latest F-Type R Coupe, in which Hennessey had given it a dose of steroids to make this wild cat a fiercer growl.

The F-Type R Coupe already comes with a 5.0-liter V8 engine producing a hefty 542-horsepower, which is simply known as a lot. But obviously Hennessey thinks that this Jag needs a little bit more power and with their HPE600, this F-Type R now prowls the streets with 623-horsepower residing in the engine bay.

Equipped with an optimized ECU, the F-Type R is also given an upgraded supercharger pulley and an improved intercooler. These changes also gave an increase in the torque figure from 502 lb-ft to 568 lb-ft. With the extra grunt, zerotohundred takes only 3.5 seconds and could run a quarter-mile in just 11.4 seconds at 202km/h.
