Weight = DIN empty weight

Manual gearbox is back. If not for quicker lap times, then for more fun and for added value after the 991 GT3 4.0 has already become a classic (which it definitely will knowing many things will change in 2019 with the new CO₂ regulations).

The 991.2 GT3 is offered for less than the 991.1 GT3 RS or the 991.1 R. The 991.2 GT3 is not slower than the 991.1 GT3 RS and with manual gearbox it is as cool to drive as the 991 R. It's a bargain! The 991 GT3 4.0 is not the ultimate GT3 as it is heavier without the roll cage than 997 GT3 RS 4.0 was with the roll cage. Remember, the 4-litre 997 GT3 had the same amount of power years and years earlier. Still, the 991 GT3 4.0 is definitely the second best GT3 after the 4-litre 997.

There isn't too much to write about the 991.2 GT3. While the PDK cars have electronically controlled differential lock, the manual cars have mechanical differential lock (locking 30% on acceleration, 37% on decelaration). The design is from the 991 GT3 4.0 Cup car unveiled in 2016 (minus the Cup rear wing). The 20" wheels and 380 mm brake discs are from 991 GT3 3.8, the engine is from 991 GT3 R (also used in the 991 R, an internally enhanced version of the 4-litre in the 991 GT3 RS) and the manual gearbox is from the 991 R (which got its gearbox from the 997). The 991 GT3 4.0 speaks for itself!

The touring version

There are many people, especially designers and stylists, who don't like the vulgar rear wing of the GT3 and prefer the classic side view of the 911 coupé as designer F.A. Porsche put it in the sixties. For the first time the GT3 is available without its huge rear wing. The 991 GT3 Touring version has the electrically erecting rear spoiler from the 991 Carrera, but with a Gurney flap on it to balance out the downforce created by the GT3 front spoiler. As the Touring version has a lower top speed, this suggests the Carrera rear spoiler with the Gurney flap generates more drag compared to the GT3 rear wing (adjusted to top speed position). Or has the gearbox different ratios? Although manual gearbox offers the utmost Porsche feeling and Porsche driving experience, inexperienced drivers feel clumsy operating the car with a clutch pedal and would prefer an automatic gearbox. The more comfortable Carrera suspension and the rear seats are what would make the Touring version perfectly bridge the gap between the 331 kW Carrera WLS and the 368 KW GT3...

Project leader Andreas Preuninger explaining the news

Nürburgring Nordschleife lap time 7:12.7

The May 4, 2017, press release announced that Porsche test driver Lars Kern had lapped the Nürburgring Nordschleife in just 7:12.7. It sounded rather unbelievable compared to 7:25 of the 991 GT3 3.8 and to 7:20 of the 991 GT3 RS 4.0. Due to the high downforce setting, the test car's top speed on the track was around 177 mph/285 km/h (198 mph/318 km/h claimed top speed on the stock car). The air temperature was just 8°C/46°F which meant the normally aspirated engine could suck a lot of air, but at the same time the tarmac temperature was 14°C/57°F which meant the grip was already good enough, while the relatively cool asphalt provided some sort of cooling to the hot tyres. Michelin Pilot Sport Cup 2 and Dunlop Sport Maxx Race tyres were tested.

Check out the video, it is mega! According to the Youtube clock the lap on the video takes around 7:18. If the Youtube clock is accurate, then this is not the lap when 7:12.7 was achieved. But who cares - 7:18 is already insane. If you have been driving in The Green Hell, then you understand it.
