Formal introductions will have to wait until the 650S replacement has its world premiere at the Geneva Motor Show on March 7th. That’s when we get to know how much power it has… and therefore, what its name will be. Guesses between 650 and 750bhp on a postcard, please…
What we do know officially from today is that the twin-turbo V8 will be appearing for the first time in 4.0-litre form, 200cc up on the engine that has been at the heart of every McLaren since the first MP4-12C five years ago.
The M840T engine is said to be a substantially new unit, with ultra-low inertia twin-scroll turbos sharpening response and reducing lag, according to McLaren. “Power, torque and throttle response are all significantly enhanced compared to the first-generation Super Series,” says McLaren Super Series line director, Haydn Baker.
At 4.0-litres it eschews the downsizing trend but it does tick the boxes for better fuel efficiency and lower emissions, says Woking. It also delivers on the aural front, delivering “a ‘crescendo’ characteristic, according to engine rpm and load.” A sports exhaust will still be optional.
