Porsche’s chief engineer for the 911 says the German firm “wanted to really make a step” with the new Turbo S, which is some 51 kW more powerful than its predecessor.

The 992-generation 911 Turbo S is powered by a 3,8-litre boxer engine featuring a pair VTG turbochargers. Its peak output of 478 kW is some 51 kW more than that of its predecessor, while maximum torque has increased 50 N.m to 800 N.m.

Porsche says the Turbo-specific eight-speed PDK transmission helps cut the sprint from zero to 100 km/h to a mere 2,7 seconds (some two-tenths faster than before), while top speed is unchanged at 330 km/h. The blast from standstill to 200 km/h, meanwhile, has improved a full second to 8,9 seconds, says Porsche.

Speaking to Road & Track, Frank-Steffen Walliser said he wanted drivers to “feel a difference”.

"If you take a 580 hp car and add another 20 or 30 extra, you won't really feel it," Walliser said. "Maybe you can measure it, but the reason for a new Turbo is that you feel something, that you feel a difference ... we wanted to really make a step," he said.

Walliser told the publication the transmission was handed a larger clutch pack to deal with the extra torque.

"You can really feel the size of the engine, and once the turbos reach boost pressure, it's really impressive. The car is a little bit more raw," he said.
