Which brings us the Racing Yellow 911 Carrera S before you. The new 911 (dubbed 991 internally) is larger, but incrementally so, as overall length grows by 2.2 in. and wheelbase grows by 3.9 in. (now 96.5). Yet overhangs are trimmed, and most important, the rear axle moves aft roughly 3 in. relative to the engine (made possible by new 3-shaft transmissions whose output flanges are moved closer to the engine), resulting in a significant tweaking of the proportions, and a slightly less rear-heavy weight distribution. Add a wider front track—a full 2.0 in. wider for the Carrera S model we tested—and you end up with a significant challenge for the design team headed by Michael Mauer.
