The Porsche 911 GT3 is the last member of the 911 family yet to receive its mid-cycle update. At the 2017 Geneva auto show in March, the covers finally come off. In typical Porsche tradition, we should see a few visual tweaks and some extra horsepower.

The updated Porsche 911 GT3 will also come with a brand-new engine.

As reported, the engine will be a 4.0-liter flat-six. It won’t be the 4.0-liter engine used in 911 R and RS but a unique unit based on the current GT3’s 3.8-liter engine. The output is expected to be at least 500 horsepower, more than the current GT3’s 475 hp.

 

The GT3 offers a 6-speed manual transmission as well, probably lifted form the 911 R, however, the 7-speed dual-clutch transmission will still be available. The dual-clutch quicker than a manual and it also boosts the appeal of the car.

Apparently, two additional models will be added to Porsche’s “GT” lineup. One is a 2017 GT2. It will have the twin-turbocharged 3.8-liter flat-six and in 911 Turbo models but with an output of around 650 hp. The engineers were apparently aiming for 700 horses but this would have required numerous modifications for cooling.

The second model is a Cayman GT4 RS. This model is also expected to sport a 4.0-liter flat-six, delivering more than the 385 hp. We can expect an output of around 430 hp and a debut in 2018.
