The engine block still consists of two parts, each with a crankcase half and a block of three cylinders. The new engines, known internally as 9A2, are complete redesigns of the existing 9A1 powerplants, although they retain the traditional flat-six layout and general dimensions of their predecessors. But Porsche also understood that while achieving the efficiency improvements demanded by the politicians of the world, it also needed to create a turbocharged engine that perpetuated the stirring sounds and high-rpm energy that 911 drivers expect. The motivation behind this change is improved fuel efficiency to meet both European and American requirements for reduced CO2 emissions. ![]() That’s because with this major midcycle update, Porsche has turbocharged the engines in even the lowest 911s and is heading toward a near-universal turbo future, following the successful trail blazed by Audi, BMW, and Mercedes-Benz.

What is different is how the steering felt between the rear- and all-wheel-drive Carreras. It's so balanced and then re-balance-able while cornering that you can position it just where you want it." As each figure-eight test was conducted at a different location, the maximum lateral grip we measured and the lap times aren't necessarily comparable and fell between 1.07 and 1.09 g and 22.7 and 23.2 seconds. "It's so controllable, so right, that you keep on wanting to experience it. ![]() "The only car that I literally had to intervene with myself to stop lapping," he said. Add to that very clever and nearly undetectable rear-axle steering, and it's the kind of car that elicits gushing praise from otherwise-sober testing director Kim Reynolds after at least a dozen laps in that MTBDC-winning Carrera. The Carrera S puts but 36 percent of its total on the front tires, the 4S at 38 percent. The only rear-engine car for sale in America offers a paralleled amount of steering feel and precision with so little weight on the front axle.
