Here's a first look at the stunning 2014 Porsche 911 GT3, which features a dual-clutch seven-speed transmission, active rear-wheel steering, a computer-controlled rear differential with torque vectoring, and "a liberal amount of aluminum in the unibody and body panels." Continue reading for two videos, more pictures, and additional information.
The powertrain of the new 911 GT3 comprises a 3.8-litre flat engine developing 475 hp (350 kW) at 8,250 rpm, a Porsche Doppelkupplung (PDK) double-clutch gearbox, and high-traction rear-wheel drive. The six-cylinder engine is based on that fitted in the 911 Carrera S, but shares only a few common parts.
All other components, particularly the crankshaft and valve train, were specially adapted or developed for the GT3. For example, Porsche is once again using titanium connecting rods attached to forged pistons. These basic modifications set the stage for an extreme high-revolution engine capable of reaching up to 9,000 rpm. The dual-clutch gearbox is another feature specially developed for the GT3, with characteristics inspired by the sequential gearboxes used in motor racing, thus granting the driver further benefits when it comes to performance and dynamics.
