2017 Porsche 911 GT3 will receive a 4.0-litre flat six engine

It looks like Porsche will be very busy throughout 2017 as it prepares for the eventual launch of its two new models this year – the 2017 Porsche 911 GT3 and the Porsche 911 GT2 RS – and the likely arrival of the new Porsche Cayman GT4 RS.

A black 2017 Porsche 911 GT3 was spotted being driven at the famed Nurburgring in October 2016 without any disguise – giving us a good glimpse on the updated looks of the newest iteration of the car. Still in the 991 generation, this Porsche 911 GT3 features a tweaked front end with more imposing air intakes on the front bumper. Its front end also comes with a redesigned front spoiler and new LED indicators. A new diffuser is also found on the rear. Its rear wing and central twin exhausts remain the same, just as its slit grilles both on the front and back.

According to reports from Auto Express and AutoCar, power will come from an evolved version of the 4.0-liter flat six engine installed in the current Porsche 911 GT3 RS and 911 R. This evolved engine could produce at least around 500 hp or around 25 hp more than the 3.8-liter engine in the present GT3. Power will be sent to the wheels through either a six-speed manual gearbox or a seven-speed PDK dual-clutch automatic transmission. Porsche is expected to unveil the new Porsche 911 GT3 at the upcoming Geneva Motor Show in March 2017.

On the other hand, Porsche’s flagship model – the new 911 GT2 RS – is expected to be out before the end of the year, as indicated by sources for Auto Express and AutoCar. Its core will be served by a more powerful variant of the 3.8-liter twin-turbo, flat-six engine fitted in the current Porsche 911 Turbo S. In the 911 Turbo S, this powerplant delivers 580 hp of max output and 750 Nm of peak torque. For the new 911 GT2 RS, this engine is tuned to deliver 650 hp.

Actually, Porsche managed to squeeze 700 hp from this engine. However, this would further increase the temperature of the engine, requiring the installation of a water injection system. So for the sake of reliability, Porsche settled for 650 hp.

Meanwhile, the high demand for the Porsche Cayman GT4 is possibly one of the reasons why people at the sports car maker are already talking about the possibility of launching a Cayman GT4 RS. Sources have told Auto Express that the Porsche Cayman GT4 RS would be powered by a 4.0-liter engine that would deliver around 430 hp of max output. When approved and realized, the Porsche Cayman GT4 RS would arrive after the Porsche 911 GT3 and the 911 GT2 RS.
