Porsche's latest customer-focused racecar has a larger, more powerful engine, and the body produces additional downforce.

Most of the new vehicles we see debut at the Paris Motor Show are for the street, but Porsche is using this year’s event for a public premiere its latest track-only racecar for customers – the 911 GT3 Cup. The coupe has a bounty of new tech that should result in lower lap times at circuits around the world in 2017.

The GT3 Cup now boasts a 4.0-liter flat-six with direct injection that produces 479 horsepower (357 kilowatts) versus a 3.8-liter engine with 453 hp (338 kilowatts) previously. Beyond the extra displacement, Porsche claims the new powerplant is more reliable due to upgrades like tougher rocker arms and an integrated centrifuge for defoaming the oil. The company adds a more rigid crankshaft, too. The transmission is still a six-speed sequential gearbox.

The new GT3 Cup also looks a little different because of small styling tweaks at the front and rear. Porsche claims the adjustments are completely functional and increase downforce, which should help lap times. If the worst happens, racers also benefit from a larger safety hatch in the roof. Despite the changes, the racecar’s total weight stays at 2,646 pounds (1,200 kilograms).

The upgraded 911 GT3 Cup will premiere during the 2017 racing season in the Carrera Cup Deutschland, Carrera Cup North America, and Porsche Mobil 1 Supercup, which travels with Formula One. It’ll begin competing in the brand’s one-makes series elsewhere around the world during the 2018 season.

The GT3 Cup is Porsche’s entry-level model for people who want to race a track-dedicated 911, and it’s a rung above the recently released Cayman GT4 Clubsport. These competition vehicles start life as regular 911s on the assembly line in Stuttgart-Zuffenhausen, and the firm's motorsport center in Weissach then installs the necessary upgrades. The company has built 3,031 of them since 1998 for racers around the world.
