Just about every modern supercar these days comes equipped with a twin-turbo V8 that makes at least 600 horsepower and a whole lot of torque. This makes for scintillating acceleration figures but one thing that is sorely lacking is a searing, captivating exhaust note that has the hairs on the back of your neck standing up every time one flies by.

Enter the Ferrari F12, powered by a naturally aspirated 6.3-liter V12, it came with 730 hp straight out of the factory and the sound out of its tailpipes is simply unreal.

It may still be a sensational machine but the F12 was first introduced in 2012 and the 789-hp 812 Superfast has since stolen some if its thunder since replacing it in 2017. Hennessey Performance however, has a solution for F12 owners as evidenced by its validation testing video which shows a white F12 being put through its paces fitted with an HPE800 performance package.

The video is long on exhaust noise but short on information. All we can glean is that this F12 is now producing an additional 70 hp over its standard counterparts, which makes it a handy 11 hp more powerful than the 812 Superfast and puts clear air between it and those pesky turbocharged V8 pretenders.

The sound emanating from the quad tailpipes is even better than we remember but for now, Hennessey has not revealed how it has achieved its power gain or what other modifications have been carried out to the car. More details are sure to be released once the car has gone through the validation process, a job by the way that we are more than happy to apply for.
