The 991.2 GT3 got an engine upgrade over the 991 which used a 3.8-litre flat-six. The new engine has now been scrounged from the 911 GT3 Cup car, which is a naturally aspirated 4.0-litre six-cylinder boxer that breathes out 500bhp and an impressive 460Nm of turning force. The GT3 is the only car in the current 911 portfolio with a naturally aspirated motor. It comes with both manual and automatic transmissions.
The GT3 gets a manual transmission, which is every purist’s delight. The automatic is the famous Porsche’s double-clutch PDK (Porsche Doppelkupplung) with paddle shifters. On the other hand, the pure manual is a six-speed unit which is a whole 15kilograms lighter. The manual will take you to 100kmph in 3.9 seconds, while the automatic manages it in just 3.4. But, when it comes to the top whack, the manual tops out at 320kmph, two more than the PDK.
The 911 GT3 weighs just 1430kilograms with a full tank of fuel (15kilograms lighter with the manual). The power-to-weight ratio is of motorsport levels. The rear differential lock is mechanically controlled. Together with the rear-axle steering as standard (for the first time in GT3), the manner in which the GT3 puts down all the power to the road is phenomenal. There are adjustable damper systems and dynamic engine mounts to keep the proceedings as stable and sporty as possible.
The GT3 cabin is a strict two-seater with a host of personalisation. The steering wheel is straight out of the 918 Spyder. The Sports Seats come as standard, but one can opt for proper bucket seats made up of carbon fibre. The upholstery is pure Alcantara. The centre screen features Porsche Communication Management (PCM) that lets the driver record his lap times which he can display and analyse on the smartphones. Apart from that, Porsche configurator lets you personalize everything from the seatbelts to the dial of the analogue clock atop the dashboard.
For an enhanced day-to-day usability, Porsche has provided the GT3 with an optional Pneumatic Lift system on the front axle. This lifts the front of the car by around 30mm. This can be done at speeds of up to 50kmph thus preventing damage to the flat underbody of the car on uneven road surfaces. The massive fixed rear-wing is made up of carbon fibre and is a characteristic feature of the GT3.
