Audi's new four-cylinder though is a radically different design that is not an I4 layout. If Audi intends to replace eight cylinder and six cylinder motors in premium models they want to reduce the vibration of a stressed four-cylinder. Audi was granted a patent for their new design which is described as an “internal combustion engine with multi joint crank drive and additional masses on articulated connecting rods for damping free inertia forces.”
Will upscale buyers care that their A8 has a four cylinder? Will they just opt for the larger motors instead? No matter what get ready to see smaller and smaller motors.
