Mclaren’s New 4.0-liter Twin Turbo Engine Powering the Super Series

Mclaren's New 4.0-liter Twin Turbo Engine

McLaren just debuted their new engine for the P14 and it’s 200cc bigger than the one it replaces. The new 4.0-liter Twin Turbo Engine increased power, acceleration and puts things into perspective.

This new 4.0-liter Twin Turbo Engine dubbed the ‘M840T’ V8 is anything but mild. The 650S is now replaced with the all new carbon-tubbed supercar called the P14. Acceleration from 0 to 124-mph takes just 7.8 seconds. That’s half a second quicker than the Ferrari 488 GTB and a full second quicker than the McLaren 675LT and just a half second slower than the Bugatti Veyron.

Part of increasing displacement meant McLaren also needed to reduce turbo lag significantly. They did so by using new ultra-low inertia twin-scroll turbocharges.

Mclaren says the new 4.0-liter twin turbo engine can propel the Super Series P14 in a quarter mile in just 10.3 seconds which is faster than Ferrari’s claimed 10.6 seconds for the 488 GTB.

The engine bay receives some sort of red LED illumination when the driver unlocks the car. Sort of like bringing the heart of the car alive.

The engine note should also sound much better than before says McLaren; “signal its performance credentials with an exhaust sound achieved through a sophisticated balance of harmonics and delivering a ‘crescendo’ characteristic, according to engine rpm and load.”

Yes, option that sports exhaust in please.

The highlight? Better sound, better performance, better everything.
