If there’s one
thing the McLaren Senna doesn’t need, it’s more power, as it is already
neck-snapping fast. However, that’s exactly what Hennessey Performance did with
their HPE1000 performance kit. It consists of upgraded turbochargers, high-flow
wastegate, intercooler, high-flow air filters, stainless steel turbo headers, a
Motec engine management system and a stainless steel exhaust. Even the
seven-speed dual-clutch transmission has been modified to better cope with the
extra muscle produced by the 4.0-liter V8.
How much power are
we looking at? The Texas-based tuner hasn’t released any official specs yet;
nonetheless, the HPE1000 moniker suggests at least 1,000 horsepower, which
would make it 211 hp more powerful than the stock Senna that sprints to 100 km/h in 2.8 seconds, as per the official McLaren spec sheet, and maxes
out at 340 km/h.
Besides the
HPE1000, Hennessey’s offering the HPE900 kit as well, with pretty much the same
upgrades, more or less, but in a slightly more restrained package – if you can
call 900 HP “restrained”. Selecting either will add ‘Hennessey’ and ‘HPE900’ or
‘HPE1000’ decals on the outside, a serial numbered dashboard plaque inside and
another one in the engine compartment. The HPE900 comes with a
3-year/57,936 km warranty, whichever comes first; since this
standard practice for their packages, we presume the same applies for the
HPE100 as well.
After completing
internal testing, Hennessey will come back with more information and some
official performance numbers,alongside a more revealing image gallery.
