Spy Shots: Porsche 911 Turbo due for upgrades, intent on beating GT-R

With Porsche releasing its revisions to the 997 911 Carrera, Carrera S and its all-wheel-drive stablemates, the automaker is turning its attention to its turbocharged 911 and is intent to regain its crown from the Nissan GT-R.
The new 911 Turbo is expected to get a boost in output by 20 hp to net over 490 hp total, along with a similar bump in torque through the use of the new direct injection system that's been implemented on the revised 997s. Not only will power increase, but fuel efficiency should grow by almost 13 percent, with a 14.5 percent reduction in CO2 emissions. The twin-turbo'd flat-six is also expected to get a slight increase in displacement, along with a new crankshaft and upgraded oil and water pump to ensure that things stay cool while thrashing the 'Ring. Expect a modified version of the new, seven-speed Doppel Kupplung (dual-clutch) gearbox to make an appearance on the new 911 Turbo, with tweaks to handle the prodigious torque of the blown mill.

The new Turbo is expected to be revealed later this year, with exterior tweaks seen on the standard 911s, including rear LEDs, daytime running lights, upgraded wheels and a new underbody diffuser similar to that on the GT3. But will it be enough to unseat the GT-R's 7:29 Nurburgring lap time? Porsche hopes so.
