We’re doubtless nonetheless weeks away from the disclosing of the new Porsche 911 GT3, however a couple of choose European media have already been invited for a journey in a prototype. These publications, corresponding to Autocar, have launched the primary particulars of the track-biased sports activities automobile, revealing some spectacular race automobile tech.
First issues first – regardless that it makes use of the most recent 992 as its base, the GT3 carries over the current car‘s engine. Regardless of early rumours of a turbocharged mill, the brand new automobile is powered by the identical 4.zero litre naturally-aspirated flat-six as earlier than, albeit with some tweaking. Zuffenhausen’s GT boss Andreas Preuninger quoted an influence determine of 510 PS, which is similar because the runout Speedster mannequin and 10 PS up on the outdated GT3.
It’s not fairly the identical engine because the Speedster, nonetheless, because the GT3 has to go tighter noise and emissions rules, so numerous work has gone into ensuring the outputs stay untouched. The excellent news is that the fettled engine remains to be able to revving as much as a stratospheric 9,000 rpm.
Drive continues to be despatched to the rear wheels by both a six-speed handbook gearbox (yay for purists!) or a seven-speed PDK dual-clutch transmission. The latter has one fewer cog than the standard 992 and comes with a correct mechanical lever as an alternative of a stubby digital toggle.
And regardless of the bigger 992 physique, the brand new GT3 will weigh the identical as earlier than, because of a brand new carbon fibre bonnet that joins the same old weight-saving options. This consists of lighter supplies, thinner glass and the elimination of the rear seats and a few noise insulation. “I didn’t need the automobile to be heavier. That was vital. It must be greater as a result of I’ve acquired the 992 physique now, however I don’t wish to carry extra weight,” stated Preuninger.
The record of GT-specific parts extends into the chassis, the place the multilink rear suspension and rear-wheel steering have been lifted from the 991.2 GT3. The entrance finish, nonetheless, is new and makes use of a double-wishbone setup (as an alternative of MacPherson struts) with parts taken from the Cup and RSR race vehicles. The automobile has been stripped of its rubber bushings and has springs which are 25 to 30% stiffer than earlier than.
The wheels are additionally taller and wider than earlier than, now measuring 20 inches in diameter on the entrance (with 255/35-section Michelin Pilot Sport Cup 2 tyres on the entrance) and 21 inches on the again (with 315/30-section rubber). The brand new Y-spoke centre-lock rollers conceal bigger 408 mm entrance and 380 mm rear brake discs, which function a race car-style pitted floor as an alternative of being cross-drilled.
All of the thorough reengineering has been hid beneath a revised aerodynamic package deal that takes the GT3 even additional into the realm of motorsports. On the entrance, you’ve acquired a a lot wider centre air consumption that feeds air into the radiator, venting air by ducts which have moved from the bumper to the bonnet.
But it surely’s the rear of the automobile the place the brand new GT3 appears to be like its most excessive. It’s right here the place you’ll discover a dramatically totally different swan-neck wing, which is mounted on the high moderately than the underside. This new design cleans up the airflow beneath the airfoil, bettering its effectivity and rising the downforce produced. A big diffuser continues to function beneath, framing the centre-exit exhausts.
Total, Porsche claims that the brand new automobile produces 50% extra downforce in comparison with the outgoing mannequin, with out a corresponding improve in drag. In fact, you’ll nonetheless have the ability to get the GT3 as a Touring, which is able to proceed to come back with a retractable spoiler as an alternative of the big wing for a extra subdued look. This specific mannequin can even not be manual-only, being out there with a PDK choice for the primary time.
