2007 Porsche 911 GT3 Coupe

When Porsche introduced the GT3, it was the most powerful naturally aspired 911 to-date. As part of the 997 series, the 3.6-liter horizontally opposed six-cylinder engine offered 415 horsepower. The 115.3-horsepower per liter was stated by Porsche to be the world's best specific output for a non-turbocharged engine. The engine featured aluminum block and heads, water-cooled, dry sump, four camshafts, four valves per cylinder, variable intake valve timing and multi-point fuel injection.

Porsche outfitted the GT3 with an active suspension setup for the track and a mechanical limited-slip differential. It was distinguished from other 911s by a lower ride height, a prominent double deck rear spoiler and an air spoiler that closely hovers above the ground. The brake rotors are over 13 inches in diameter, front and rear, with six-piston calipers in the front and four-piston binders in the back. Porsche ceramic composite brakes were available as optional equipment.

This Porsche 911 GT3 is finished in a black exterior with black leather and Alcantara interior.
