Porsche's New 911

KOMPAS.com - Porsche is giving its standard-setting 911 a major overhaul. And this is the best look yet at the new model as it undergoes high-performance testing at Germany's famed Nurburgring track.

The latest iteration of the benchmark sports car will deliver more performance but improved fuel economy. Ignore the large air-intakes in front of the rear wheels, they are fakes.

Design boss Michael Mauer says aerodynamics hold the key to better efficiency. As these spy shots show, the new car features more upright headlights and re-positioned mirrors; proving every little tweak counts.

But Porsche knows it can't fiddle with the car's iconic shape too much. That is where active aerodynamics - wings and spoilers that adjust depending on speed - play an important role. That could explain what appears to be a movable wing at the rear.

Porsche is promising a radical overhaul under the skin but the flat-six engines will remain; albeit with updates. The car is likely to be unveiled at September's Frankfurt motor show.
