What could anyone
possibly do to the McLaren 720S to make it even hotter? Why, if you’re
Hennessey, then the obvious answer is injecting it with even more power. The Texas-based tuner has given it the HPE900
treatment, which consists of upgrading a lot parts in the engine compartment,
including the turbocharger and intercoolers, adding high-flow air filters and a
stainless steel exhaust, and recalibrating the ECU.
As a result, the
4.0-liter V8 now pushes out a whopping 809 hp and 850 Nm of torque at the wheels. The official McLaren spec sheet says the
stock 720S has 710 hp and 770 Nm of torque at the
crank, which allows it to hit 100 km/h in a mere 2.9 seconds and a
maximum speed of 341 km/h.
From the outside,
you can tell the modded 720S by the ‘Hennessey’ and ‘HPE900’ logos. There’s
also a serial numbered dash plaque in the cockpit and another one in the engine
compartment. Hennessey is offering all upgrades with a 3-year/36,000-mile
(57,936 km) warranty, and the HPE900 kit for the 720S is no exception, giving
potential owners who yearn for even more power peace of mind.
