The current 911, called the 997, is the best-seller of any in the model's half-century history. While performance improvements at its release were innovative and somewhat revolutionary for the 911, designers made sure to pay aesthetic tribute to the 911's past. The tear-drop headlights of the 996 were replaced with modern bug eyes; other details made reference to the 993 in particular.
The 997 received a minor cosmetic facelift in 2009, and the engine was bumped from 3.6-liter to 3.8-liter (500-hp). A number of significant variants have debuted during this generation, including the 911 Turbo (3.6-liter, 473-hp, 2006-current); GT2 (3.6-liter, 523-hp, 2007-current); the GT3 (3.8-liter, 409-hp, 2006-current); and the GT3RS (3.6-liter. 612-hp, 2006-current).
