Tuners love modifying the Porsche 911 because it starts as an excellent platform for adding even more upgrades. The German company SSR Performance creates the GT from the current 992-generation 911 Turbo and pushes the output to 848 horsepower (860 PS) and 701 pound-feet (950 Newton-meters). There's a limited production run of just 10 examples.
SSR achieves the extra power by modifying the turbos, revising the intake, upgrading the charge air cooling system, and changing the exhaust. There's also new engine and transmission software. The company doesn't provide acceleration specs, but there's an electronically limited top speed of 210 miles per hour.
