Porsche unleashes the new 911 GT3

Porsche 911 GT3 is the seventh edition of the high-performance sports car, developed in collaboration with Porsche Motorsport.  Its double-wishbone front suspension and aerodynamics with swan-neck rear wing mounting and striking diffuser originate in the successful 911 RSR GT racing car, and the 375 kW (510 PS) 4.0-liter six-cylinder boxer engine is based on that of the 911 GT3 R.

This is the first time that a suspended rear wing has been fitted on a Porsche series production car. Its swan-neck mounting is used in a similar form in the GT racing car 911 RSR and the one-make cup racing car 911 GT3 Cup. Since two aluminum brackets now hold the wing element from above, the airflow can pass undisturbed across the underside, which is aerodynamically more sensitive.  In the performance position, the manually adjustable wing and diffuser elements significantly increase the aerodynamic downforce for high cornering speeds.

The new 911 GT3 accelerates from zero to 100 km/h in 3.4 seconds, and has a top speed of 320 km/h (318km/h with PDK).  The engine is based on the racing engine of the GT3 race car 911 GT3 R, and is also used virtually unchanged in the 911 GT3 Cup. GT3 weight is 1,418 kg with the manual transmission and 1,435 kg with the Porsche dual-clutch transmission (PDK). 

The front bonnet made of carbon fibre reinforced plastic (CFRP), lightweight glass windows, optimized brake discs and forged alloy wheels ensure a focus on weight-saving, as does the rear compartment cover. The lightweight sports exhaust system reduces weight by no less than 10 kg. With electrically operated continuously adjustable exhaust flaps, it combines a highly evocative sound experience with the Euro 6d ISC FCM (EU6 AP) emissions standard. The combined consumption of the 911 GT3 is 12.4 (with manual transmission: 13.3) l/100 km.

The cockpit is in line with the current model generation. But a new feature is the Track Screen. At the touch of a button, it reduces the digital displays to the left and right of the central 10,000 rpm rev counter to information such as tyre and oil pressures, oil and coolant temperatures, and fuel level, which are essential when driving on the track. It also includes a visual shift assistant with colored bars to the left and right of the rev counter, as well as a motorsport-derived shift light.

Other highlights include exterior mirror tops made of carbon, darkened LED matrix main headlights and matching Exclusive Design rear lights with an arc of light with no red components. Indian Red or Shark Blue painted wheel rims enhance the black alloy wheels. In the interior, equipment details such as the dials for the rev counter and Sport Chrono stopwatch, seatbelts and trim strips.

The new Porsche 911 GT3 has a starting price of 167,518 euros.
