The Details:

• Hennessey Performance tunes McLaren 12C

• HPE700 goes 0-60mph in 2.8sec with an output of 704hp

• Package costs $19500 and includes stainless steel exhaust system

• ECU software upgrade also improves power

Texas tuning company Hennessey Performance remains true to its motto of, “Making fast cars faster since 1991” by delivering an upgraded 704hp McLaren MP4-12C. Called the HPE700, the package delivers an estimated 14 percent more power than the stock 12C, which is powered by a 3.8L V8 32v DOHC twin-turbocharged engine with an output of 616hp. This makes it an attractive alternative to McLaren’s new P1 hybrid supercar as the 2013 12C carries an MSRP of $239400 base. The P1 hybrid is priced at $1.15 million and has a total output of 903hp.

For an additional $19500 one can obtain the Hennessey package, which increases the McLaren’s output to 704hp at 7500rpm and 538 lb-ft of torque at 5800rpm, enabling a 0-60 sprint of 2.8sec and a scorched-earth quarter-mile time of 10.3sec at 137mph. According to Hennessey, the extra power is made possible by an ECU software upgrade that increases peak boost from 21 to 23 psi.

The extra boost in power places a stock 616hp McLaren 12C ahead of rivals in a standard acceleration test such as the Ferrari 458 Italia, which delivers 562hp, 398 ft-lb and a top speed of 202mph.

David T., owner of the first McLaren HPE700 had this to say, “I gave you an extremely fast car, and was given back a starship with advanced trans-warp drive. For the first time in my life (and I really mean the first time), I might actually have achieved fast enough, and that is a place I never thought I’d reach. After all, why would anyone mess with the square root of exhilaration?”

With the Hennessey package, a stainless steel exhaust system is included, along with high-flow air filters and aluminum serial-numbered Hennessey plaques for both the engine compartment and interior. Each HPE700 McLaren is thoroughly dyno-tuned and road-tested, and is backed by a 1-year/12000-mile limited warranty. If the McLaren P1 hybrid supercar is a bit of a stretch, perhaps the HPE700 is worth looking into.
