Newest Porsche 911 GT3 Cup Car Is a Buffer, Better Best-Selling Race Car

From the Nürburgring to Sebring, WEC to IMSA, the hunchbacked, rear-engined 911 GT3 Cup is an extremely familiar sight at racetracks around the globe. Porsche says the GT3 Cup is the world’s best-selling race automobile, and the corporate simply pulled the silk off of its latest incarnation: the seventh-generation, 992-based 911 GT3 Cup. Now, this best-seller is wider, stronger, and quicker than ever earlier than.

Porsche says the brand new automobile, derived from the street-legal 911, is as much as one % quicker per lap than 991.2-based GT3 Cup; round which monitor isn’t clear, so we expect the automaker is referring to a common projected common right here. “So what?” you could be pondering. Whereas only one solitary % of 1 solitary lap doesn’t sound that unbelievable, when added up over the course of dozens (if not a whole bunch) of laps, it makes an enormous distinction.

A part of that seemingly small lap-time shave comes from a little bit further energy. The brand new GT3 Cup’s 4.0-liter, water-cooled flat-six now makes 510 hp, 25 greater than its predecessor. It’ll rev to eight,400 rpm (up from 7,400) and may also, for the primary time, be run on artificial fuels. Porsche has been wanting closely into alternate options to gasoline, and whereas the automaker doesn’t say whether or not or not the engine makes much less energy when run on e-fuels, it does observe a big drop in carbon emissions. That’s no dangerous factor.

The automobile’s engine is linked to a racing-spec sequential six-speed gearbox that weighs simply 159 kilos (Porsche’s manufacturing PDK dual-clutch computerized weighs nearer to 260 kilos). Porsche says the gearbox is even quicker-shifting than earlier than, with gearchanges actuated by way of the carbon-fiber shift paddles behind the steering wheel. For the primary time in a 911 GT3 Cup, the steering is {an electrical} energy help system, getting rid of the necessity for the outdated mannequin’s hydraulic pump and fluid traces.

The brand new GT3 Cup additionally contains a wider, 911 Turbo–spec body; the resultant enhance in monitor width helps to extend grip relative to the earlier GT3 Cup automobile, which was primarily based on the narrow-bodied 911. The GT3 Cup is now 1.1-inches wider than the outdated automobile and might accommodate 12-inch-wide wheels up entrance and 13-inch-wide wheels on the rear. The entrance finish of the brand new GT3 Cup adopts a double A-arm entrance suspension setup just like the top-spec 911 RSR (and the brand new road-going GT3) however maintains a multi-link setup on the rear. Brakes are race-spec steelies by Brembo.

The Cup’s contemporary new bod is now 70 % aluminum and 30 % metal. The earlier GT3 Cup was largely metal, however since aluminum is way lighter than metal, the brand new automobile weighs precisely the identical because the outdated automobile (2,778 kilos dry) regardless of its wider physique. To assist attain that low weight, the inside is awash with carbon fiber. The steering wheel and dashboard are each manufactured from the stuff and the 10.3-inch digital instrument cluster has been revamped for the brand new yr.

Widening a automobile impacts the oh-so-delicate aerodynamic steadiness engineers should strike between downforce and drag. Fortunately, the 992-based GT3 Cup has a completely new aero package deal to nip that tough downside within the bud. The rear wing is all-new and adopts an adjustable, swan-neck design for each better downforce and decreased drag. There’s additionally a model new entrance finish with NACA-style air ducts to each information airflow across the automobile and support in cooling. On a extra mundane degree, Porsche additionally went to nice lengths to make restore diagnostics simpler, keep the outdated automobile’s reliability, and make the driving force as snug as potential.

All that to say the brand new 911 GT3 Cup needs to be one wild (and improved) experience, and it’ll make its debut on the inaugural Porsche Carrera Cup North America race in March of subsequent yr.
