Porsche has officially introduced their 911R at the Geneva Motor Show, bringing what the brand calls a "pure-bred sports car built to a time-honored formula." The exterior keeps the design classic, doing away with some of the aero details recently seen from the GT3 RS, but finished with eye-catching red stripes. The interior also blends new and old, including carbon-fiber bucket seats and sports accessories, but with a retro atmosphere. Under the hood, a flat-six 4.0-liter engine delivers 500 HP and 340 lb-ft of torque via a six-speed manual gearbox. Porsche is already taking orders with deliveries beginning this summer. Until then, see more of the new Porsche 911R below and follow our Geneva coverage here.
