- “The best 911 ever.” With every new generation of the sports car classic comes the expectation that it is even better than its predecessors.
- Attempting to make the perfect sports car even better is both an honor and an obligation. The new 911 once again succeeds in setting new benchmarks thanks to its sporty design, intelligent lightweight construction and new technologies – and is even sportier and more suitable for day-to-day use than its predecessor.
- The new 911 is the first to be completely redesigned in the last 15 years. It has grown by 2.4˝ (6 cm) to 14.75’ (4.50 m) in length. One of the most noticeable changes, however, is the 3.9˝ (10 cm) longer wheelbase, which is clearly evident in the enhanced driving dynamics and the larger cabin.
- Steel and aluminum have been combined in a perfectly coordinated hybrid design that has made it possible to reduce the weight of 3042 lbs (1,380 kg) by 77 lbs (35 kg) despite the increased dimensions.
