2021 Porsche 911 GT3 Specifications

By | January 2, 2021

The 2021 Porsche 911 GT3 is preparing to race back into the showrooms with its wild-looking rear wing and racing car hardware. The former is a special design feature that is on the top rather than the bottom and, according to Porsche, really improves aerodynamics.

The latter includes a multi-link front suspension – a first on a 911 road car – inspired by the company’s racing division. While the new GT3 debuts for the 992-generation 911, it will include an upgraded version of the a fabulous naturally aspirated 4.0-liter flat-six that powered the outgoing GT3.


The design of the new GT3 is similar to a more sculpted version of the 992-generation 911. The prototype photos provided by Porsche show that it has a larger fender, a more aerodynamic hood and a larger front air intake. The biggest difference is the gigantic rear wing, which makes the GT3 look even sportier.

This powerful variant will also have a racing-inspired double wishbone front suspension, a first for the sports car. And while the new GT3 is technically larger than the previous iteration, it weighs 3,100 pounds thanks to some design tweaks, a carbon fiber frink, and lighter-weight glass.


The interior of the 991 GT3 is predictable compared to the Carreras. The instrument is specific to the GT3, a large central rev counter that is framed by shift lights like a racing car. The modes that can be selected by the driver are refreshingly reduced to just three: normal, sport and Track. Each mode can be configured in its own parameters. Carreras’ wet mode is not displayed on GT3.

A body-hugging bucket seat and a choice of comfortable seats are provided. Options are limited to the notable numbers, including a front axle lift system and a lighter PCCB brake. Under the black panel there is a certain launch color – Preuninger always had a story about the color of the GT3 at the launch. The Shark Blue is added to the Porsche palette with this car, inspired by the Preyinger superyacht with a blue hull that he discovered while on vacation with his family.


Good news comes from the drive department. The naturally aspirated 4.0-liter six-cylinder is taller than the previous 911 GT3, and even because of its superior evolution, the 991 Speedster engine with a single throttle valve. The outstanding responsiveness and agility of the engine, not to mention the expected output of over 500 hp and a speed of 9000 rpm.

The engine is combined with a precise six-speed manual transmission – which we prefer to the standard seven-speed manual transmission 992 – or a seven-speed PDK dual-clutch automatic transmission. The Preuninger team listened very carefully to the customer, so that the manual spin-matching system could be completely switched off.
