Hennessey McLaren 12C HPE700


The McLaren 12C and Ferrari 458 Italia battle is one of the great supercar rivalries of our time, one given additional spice recently by Texan tuner Hennessey adding a couple of turbos to the latter and extracting 738hp.

Subtle badging is all that gives the game away

Now, if you're on the McLaren side of the argument and feeling a little left out fear not; Hennessey is fuelling the arms race with the announcement of a similar package for the 12C. Like the 458, it's badged the HPE700 and builds on McLaren's existing twin-turbo 3.8-litre V8 by boosting power to 704hp and 538lb ft from the standard 625hp and 443lb ft. Which is an interesting comparison with the 737hp and 531lb ft the related P1 motor delivers, albeit before the additional 179hp and 192lb ft of the electric motors is factored in.

Thing is, does this give you P1 pace for $19,000, rather than the $1,150,000 McLaren is asking for the hybrid hypercar? And, more importantly perhaps, does it mean you can out-drag your mate who's just added Hennessey's HPE700 turbo package to his 458?

Hennessey claims a 2.8-second 0-60 time, matching that recorded for its turbocharged 458 and the quarter-mile times are barely two-tenths apart (10.3 for the McLaren) with terminal speeds matching at 137mph. So they're still evenly matched, just a little further down the road than the stock versions. By Hennessey's own VBOX acceleration tests the uprated car is a second faster 60-130mph at 7.15 seconds than stock and "flat out, scalding fast" according to Hennessey's communications manager Doug Kott.

"Flat out, scalding fast," according to Hennessey

The extra performance hasn't come easily though, the full story available to read on Hennessey's website but necessitating a water/methanol injection system to cool the charge air at high boost pressures to reduce the risk of detonation. This is managed by a piggybacked ECU upgrade, new air filters, a new exhaust system and modifications to the heat exchanger cooling systems.

And beyond surprisingly tasteful badging that's it...

    That way lies Masonry.
    Or Singer, or Underground Racing, or Stasis, or Lichfield - why only name Mansory as if anyone wanting to remotely personalise their car is automatically choose them?? Furthermore, I don't even know if the Yanks are aware of Mansory anyway...

    Exactly this........tuning aside, that looks marvellous in the grey.
    A bit off topic I know, but that was my first thought - it looks great in grey with the black carbonfibre side thingies ! And I reckon the standard horsepower would be enough to entertain me ! For a while anyway...

    i drove a 12c to work this morning in the rain. It is already way too powerful to get its power down in bad weather conditions which i guess is not a situation this car often finds its time spent but a huge amount of fun, more so than in the dry where speeds that would require jail time are required before the fun starts. I just dont know where u can really use its current full power in the dry let alone more. This and the 458 need a track as do most modern supercars. I spend most of my time in my 76 911 which is a blast no matter what u are up to. I dont have the self control to live with most modern fast cars in factory spec without being able to expend them at the track.
    Good to hear a genuine input from someone that has real world experience of this actual car.
    I have driven a 12C as well, admittedly only for 3 laps of a circuit, and I can concur, it is a devastatingly fast car. Properly datum changingly fast and I had a Westfield for 15 years that was timied to 60 in 4.6 seconds, with the opportunity of a tenth or two more if you really threw away the mechanical sympathy, and 0-100 in 11.5 seconds with an horrific change to 3rd, so would comfortably go sub 11.

    Unless you are taking it on track there is just no need for the extra power, you aren't going to use it on the road.
