When Porsche decided to retire manual gearbox in 991 GT3, many customers were unhappy - sure, PDK is best for performance, but, in this age of drive-by-wire steering, throttle and brakes, manual gearchange was one of the last analog man and machine interactions left.
Porsche tried to compensate by releasing new GT models with manual as standard - the Cayman GT4 and Porsche 911R. Reception and sales were better than anticipated and this led to complete reversal of strategy for the GT3 line and return of 6 speed manual gearbox alongside PDK for the facelifted 991 GT3.
The new GT3 also has revamped engine, now at 4 liter capacity, 9000 rpm redline with 500 horsepower, optimized aero for 20% more downforce (with no extra drag) and minor cosmetic updates.
0-100 time is quoted as 3.4 seconds for the PDK version and 3.9 for manual.
