It’s hard to choose just one thing, but the howling 9,000 rpm 4.0-liter flat-six makes this car. It produces 502 hp and 346 lb-ft of torque, and it makes you work hard for every single one of those horses. Both gearboxes are no-cost options, and both provide an exhilarating driving experience. The PDK is more suited for daily driving, which you can now do thanks to dual-zone climate control and a 10.9-inch infotainment system with all the modern amenities. The new double-wishbone front suspension makes the GT3 a more suitable daily partner, but it was inspired by Porsche racing cars, so it also helps the front dig in deeper.
