Manual gearbox is back. If not for quicker lap times, then for more fun and for added value when 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 engine 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!

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. The reason for the unbelievable time was that the test car had the final drive similar to the GT3 Cup car, which meant the top speed was rated at around 177 mph/285 km/h (198 mph/318 km/h 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 on Nordschleife, then you understand it.
