Grey Porsche GT4

The flat-six at the heart of this car, while it displaces 4.0 liters like the one in the temporarily discontinued 911 GT3, is not at all related to that engine. Instead, it is a naturally aspirated development of the twin-turbocharged family that powers the 911. Porsche did a lot more than just pull off the snails before shoving it into the 718, though. Increases in bore and stroke swell displacement by a liter, and the heads, manifolds, crank, and other internals are new. Cylinder deactivation shuts down one bank under light load, alternating banks every 20 seconds to balance wear. Does it work? Can you feel it? On the highway, the activation sounds a bit like an exhaust leak, which led us to reflexively disable it by deactivating the stop-start system at startup. This comes with the added joy of listening to a naturally aspirated flat-six’s raspy idle.

With all of that being said, taking this GT3 to the next level, it has also been outfitted with a set of center lock 20×9 / 20×11 Brixton Forged R11-R Targa Series 3-Piece forged wheels. Enjoy.
