The powerplant

While the 718 GT4 racing car has a 3.8 litre engine with 313 kW, the street version has a 4.0-litre engine with 309 kW. The 4-litre naturally aspirated 6-cylinder engine is not from the 383 kW 991.2 GT3 RS, but based on the same engine family as the 3-litre turbo engine in the 992.1 Carrera with GPF gasoline particulate filter emission control system. The maximum engine speed is 8000 rpm. In part-load operation, the new adaptive cylinder control temporarily interrupts the injection process in one of the cylinder banks to reduce the production of CO2. Piezo injectors are used for direct fuel injection for the first time in a high-revving engine. They split each injection process into up to five individual injections to help to reduce emissions. The car naturally comes with the mechanical differential lock and PTV Porsche Torque Vectoring. Porsche doesn't say the actual Nürburgring Nordschleife lap time, but says it is more than 10 seconds faster than on the predeceding 981 GT4.

Downforce - added at the back, decreased at the front

The car comes with a newly designed rear silencer which creates space under the car at the rear for a functional diffuser, which at 124 mph/200 km/h adds approximately 16 kg/35 lb to the downforce. This makes around 30% of the rear axle downforce. At this speed the rear wing produces approximately 6 kg/13 lb more downforce (approx. +20%) than on the predecessor. The rear wing and the diffusor add approximately 22 kg/48 lb downforce at the rear axle compared to the 981 GT4. The front axle downforce has decreased by around 10 kg/22 lb. Considering the decreased downforce at the front and the added downforce at the rear axle, the 982 GT4 has 12 kg/26 lb more total downforce at 124 mph/200 km/h than its predecessor.

Weight

Based on the numbers presented by Porsche, the 982 generation GT4 is 80 kg/176 lb heavier than the 981 GT4 was. It is compensated with the larger and more powerful engine resulting in 3% better power-to-weight ratio for the newer car. The optional Clubsport package includes the steel roll bar behind the seats, the fire extinguisher and the 6-point seat belt for the driver.
