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!
