In just under a month, McLaren will reveal its much-anticipated successor to the 650S at Geneva rumored to be called the 720S. So far, we know that the first of McLaren's second generation Super Series will have a new hi-tech active chassis, and be twice as aerodynamically efficient as the 650S. Of course, what we're really interested in is how it performs. McLaren has now revealed new details about the new Super Series' specifications, which will "raise previously accepted limits of supercar performance."

Powering the 720S will be a new 4.0-liter, twin-turbocharged V8 that provides potent performance, allowing the new Super Series to hit 0-124mph in, wait for it, 7.8 seconds, and blitz a standing quarter mile in just 10.3 seconds. McLaren, you have our attention. "The new 4.0-liter M840T is an outstanding engine powering an exceptional supercar capable of covering a standing quarter mile in 10.3 seconds," McLaren Super Series Vehicle Line Director Haydn Baker said. "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 "soulful" sound of the twin-turbo will also enhance the experience, with a crisp exhaust note that is "among the most emotive of any McLaren." An optional sports exhaust can also be fitted, if you want a more earth-shattering aural assault. Compared to previous McLaren Super Series, the ultra-low inertia, twin-scroll turbochargers fitted to the new M840T will have a sharper response thanks to reduced turbo lag and quicker throttle response. Its V8 heart will be prominently exposed through a cast-aluminum air intake plenum, so you can be the envy of everyone, and the engine bay also illuminates whenever the vehicle is unlocked, just to remind you that it means business.

Final engine and performance specifications will be confirmed on March 7th when the 720S makes its public debut at Geneva. McLaren probably isn't too pleased that the surprise has already been spoiled, though - we already know how the new Super Series will look, thanks to a revealing photo from a customer pre-reveal event leaked for our viewing pleasure.
