More features usually found on hybrids and small cars for increased fuel saving measures include a new electric power-steering, which is significantly lighter than past hydraulic set-ups, but offers a very good amount of feel and ramp-up in effort as speeds increase feels very natural and organic.
The 3.4 produces 350 hp, up from 340 from the 997, and the Carrera S makes 400 hp, up from 385 from its predecessor, both engines revving to a racier 7,800 rpm redline and yet are very tractable at 2000 rpm in 7th gear to lug the Carrera and Carrera S around town at speeds of below 40 mph.
The most impressive feature that all future 991 owners will appreciate is the PTV and PTV + torque vectoring system, first seen on the luxurious Panamera 4-door sports limousine. In conjunction with the active hydraulic anti roll-bars and the Porsche Active Suspension Management or PSM, the PTV adjusts roll-stiffness by increasing hydraulic pressure on the outer wheel’s hydraulic roll bar when cornering hard and applying some brakes to the inner wheel to help the rear-end rotate. The technology was pioneered in the 997 GT3R Hybrid race cars on the infamous 24 Hour Nurbugring Endurance Race.
