Images of the updated 2015 Porsche 911 Turbo have already surfaced on the web ahead its public debut expected to take place at the Frankfurt Motor Show in 2015.

These images are said to be the first to completely reveal the entire exterior of the 2015 Porsche 911 Turbo facelift. The cosmetic revamp seems to include subtle changes to the rear spoiler which has been reshaped; so has the headlight graphics, while the taillights have been tweaked to seem slightly longer.

Power is rumoured to come from a 3.8-litre six cylinder turbo engine, which could be upgraded to as much as 441 kW of power. As part of a new strategy, the entire range except for the GT3 and GT3 RS could be upgraded with a turbocharged engine.
