All-new 4.0-liter V8 for next-generation McLaren roadcars

0

The second-generation McLaren Super Series, which will make its public debut on March 7, 2017 at the 87th Geneva International Motor Show, has been further teased by the UK manufacturer. The new unit is said to build on the performance benchmarks achieved by the first generation M838T unit, and dispatch the sprint from standstill to 200km/h (124mph) in just 7.8 seconds. McLaren states that this is accompanied by a ‘soulful, clean and crisp exhaust note’.

“The new 4.0-litre M840T is an outstanding engine powering an exceptional supercar capable of covering a standing quarter mile in 10.3 seconds,” commented McLaren Super Series vehicle line director, Haydn Baker. “Power, torque and throttle response are all significantly enhanced compared to the first-generation Super Series, yet with fuel efficiency and emissions also notably improved.”

The ultra-low inertia, twin-scroll turbochargers fitted to the new M840T engine are said to typify the engineering philosophy of advancement in every area, ‘pursued throughout the development of McLaren’s new supercar’. Their faster spool time helping reduce lag, ultimately improving driveability and throttle response.

The new 4.0-litre engine also benefits from extensive development of the exhaust sound, with the end product said to achieve a ‘sophisticated balance of harmonics and delivering a ‘crescendo’ characteristic, according to engine rpm and load’. To take this further, a sports exhaust is available as an optional extra.

Owners will also be able to showcase the heart of their new car – in particular, the cast-aluminium air intake plenum with McLaren Speedmark logo on top of the new V8 engine – with engine bay illumination that operates on vehicle unlocking.

More details of the second-generation McLaren Super Series, including engine and performance specifications, will be confirmed at the Geneva unveil.
