Hennessey Performance has unveiled an 800 horsepower Ferrari F12 upgrade and we’re not sure how to feel about it.

Hennessey has, historically, been all about making North American vehicles better versions of themselves. That almost universally meant adding more power at the expense of pretty much everything else (see The Exorcist for a pretty good example).

Now Hennessey seems to be branching off into new territories. Supercharged and super-powerful pickups aren’t too much of a stretch, but European supercars? And not just European models, but Italian supercars like Ferraris? That just seems somehow… unwholesome.

Not that being unwholesome ever stopped Hennessey.

Here we have a Ferrari F12, in white, scooting around Hennessey’s test track for “validation”, according to the video description. The video also describes the car as having an 800 horsepower upgrade, which isn’t too far from the F12 Berlinetta’s initial 730 horsepower from its naturally aspirated 6.3-L V12 engine.

Stock, the F12 could race from zero to sixty in 3.1 seconds, zero to 124 mph in 8.5 seconds, and reach a top speed of 211 mph. Even the F12tdf, with its up-tuned 769 hp engine, could only reach 60 mph from a standstill in 2.9 seconds. With 800 horsepower available, we expect Hennessey’s upgrade to be faster still.

We don’t have any information on just what exactly Hennessey has done to the Ferrari F12, but given the fact that 800 horses is relatively close to where the F12 started, the HPE800 upgrade is probably fairly light. Their newly developed McLaren 720S HPE800 upgrade makes a similar leap in power and all that required was a new exhaust, high-flow air filters, and a bit of tweaking to the car’s ECU.

So far, there’s no information on Hennessey’s website, so this is either a special one-off project or they’re just getting started with working on Ferraris. We’re still not sure how to feel about their latest project, but maybe we’ll feel better after they release a few more details.
