Loyalty to the horizontally-opposed engine has much more than just an historical basis. All horizontally-opposed piston engines are characterized by an excellent balancing of masses.
Smooth performance is the pleasing result.
And, the engine's flat design supports engineers' efforts to lower the vehicle's center of gravity. All the experience gathered by Porsche in the last 34 years with the six-cylinder engine, in both everyday driving and the heat of motor sports, was directed into the design of the new boxer engine. The possibility of increasing performance was not the only reason for the new design with potentially more complicated technology. The consistent pursuit of lower consumption rates, the reasonable use of energy sources and minimal pollutant emissions or other substances that affect the climate were more decisive.
