The latest addition to the legendary lineup is the first racecar based on the current 992 generation, and it brings the latest technological advancements bundled up into a spectacular turbo-spec wide body. It measures 1,902 mm (75 inches) in width, exceeding the rear width of the earlier model by 28 mm (1.1 inches).
Underneath the beefed-up body, the optimized chassis borrows the 991 RSR’s double-wishbone front layout using Uniball bearings that protect the new adaptive dampers from lateral forces, which should translate into crisper handling.
Compared to the previous generation, which used a predominantly-steel body, the new GT3 Cup employs an aluminum-heavy construction with only 30% of the structure being made from steel.
For the doors, engine hood, and rear wing, engineers used carbon-fiber-reinforced plastic, while the front hood that includes an exit-air duct and central air intake is made of aluminum to lower repair costs in case of a crash.
Inside, Porsche designers improved the cockpit focusing on driver ergonomics. The new racing seat can now be adjusted in two height settings. A wide range of padding thicknesses is available to ensure the perfect seating position for each driver.
The adjustable steering column comes with a fully redesigned, open-top, multifunction steering wheel made from carbon-fiber. Its illuminated buttons have been relocated for easier use, following drivers’ feedback.
Power is provided by a naturally aspired 4.0-liter, water-cooled flat-six engine, which develops 510 hp (375 kW). It uses a dry-sump lubrication system to ensure optimal operation through high-speed corners.
It also uses a single throttle butterfly system with two resonance flaps for sharper acceleration and a state-of-the-art Bosch MS 6.6 electronic engine management system.
Three different exhaust systems are offered to conform with all racing series regulations, and each one of them enhances the extraordinary sound of the glorious flat-six.
The engine is connected to a six-speed dog-type sequential gearbox via a single-mass flywheel and a three-plate sintered metal racing clutch. The shift barrel actuator is controlled by a new electric servomotor, which replaces the old pneumatic unit enabling faster gear changes and live diagnoses.
Starting next season, the new Porsche GT3 Cup will take part in various competitions like the Porsche Mobil 1 Supercup as well as the national Carrera Cups in Germany, France, Asia, and Benelux. It’s also scheduled to debut in North American competitions for the first time.
