In its never-ending search for quicker and quicker lap times, Porsche has updated the highly popular 911 GT3 Cup racing car with a new, more powerful engine, enhanced reliability, and extra aerodynamic tricks along the body panels.
The update coincides with the release of the second-generation 991, a.k.a. the 991.2. Porsche unveiled the 991.2 last year, but the GT3 Cup stands apart from its road-going brethren as the track-only, race-ready variant aimed at hitting the starting grid right out of the box.
Per usual, you’ll find a flat six-cylinder engine mounted in the rear. This time around, the powerplant comes packing with direct fuel injection, an even four liters of displacement, and 100 percent naturally aspirated induction (cue cheering fan boys).
The 4.0-liter powerplant replaces the outgoing model’s 3.8-liter flat-six, with peak output rated at 485 horsepower – an increase of 25 ponies. Not bad for a car that weighs less than 2,700 pounds.
In addition to being more powerful, the 4.0-liter six-cylinder is also more reliable, offering a valve drive with rigidly mounted rocker arms and a central oil feed – a first for the model. There’s also an integrated oil centrifuge for enhanced oil defoaming, and a more rigid crankshaft.
Making the most of the newfound power is upgraded aero, which takes a few cues from the most recent 911 facelift. There’s a new front bumper apron, and a new rear end. Porsche declined to specify exactly how it managed to “improve” the aero, but did mention “enhanced traction and performance,” so I’m guessing there’s just more downforce. Meanwhile, you’ll find the same rear wing as the outgoing model, measuring in at 184 cm in width. That’s over six feet, by the way.
