Today, Porsche debuted a new 911 variant at the IAA Mobility show in Munich, Germany. It’s the most powerful 911 to date, excluding some limited-run models, and may well be the quickest to 60 mph from a standing start, dispatching that dash in just 2.4 seconds. And it’s all thanks to one of the most interesting hybrid powertrains on sale today.
Rather than just bolting an electric motor to an existing 911, Porsche designed an entirely new 3.6 L flat-six engine, taking the opportunity to ditch the belt drive and move some of the ancillaries, which can instead be powered by the car’s 400 V traction battery.
The system debuted in the 911 GTS T-Hybrid, which Ars recently reviewed. For that car, Porsche added a single electric turbocharger, which works like the MGU-H in a Formula 1 car. It spins up almost instantly to 120,000 rpm to eliminate throttle lag, but also recaptures excess energy from the spinning turbine and sends that to the 1.9 kWh battery pack.
