Things are about to heat up in the supercar wars. At the upcoming Geneva Motor Show in Switzerland, McLaren Automotive will unveil its new 720S, a replacement for the 650S that had us so smitten. The company showed us a glimpse of the new car's carbon fiber tub at the start of the year; called Monocage II, it's stiffer than before and will help the new car weigh less than its (already light-as-a-feather) predecessor. And on Wednesday, the company revealed that performance will also get a significant boost.
Plenty have waxed rhapsodic about the M838T engine that powers the current generation of McLarens, and the M840T builds on that base. It has grown to four liters and gets new faster-spooling, ultra-low inertia, twin-scroll turbochargers. That's going to make the new car blisteringly fast. "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," said 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."
