With 40 years of fine-tuning, you would expect the 911 to be a well-honed car by now. And with the new 911 Carrera GTS, it's easy to see how all this work paid off.
Despite the engine's being naturally aspirated, Porsche manages to get better than 100 horsepower per liter out of it, while at the same time delivering reasonable, if not stellar, fuel economy. The relatively light weight of the car is apparent when you first get behind the wheel. It dances through turns.
And the 911 has come a very long way, with new technology added over the years increasing the performance even more. A sport mode gives it more aggressive throttle mapping, an active suspension helps keep it grounded, and there is even a button to make the exhaust louder.
Cabin electronics are less exciting, although much advanced over what Porsche offered just five years ago. The navigation system will keep you out of traffic, and the phone system makes it easy to place calls on the road. The best part is the stereo, with audiophile sound quality.
