The engine has four valves per cylinder, with chain-driven double overhead camshafts, and variable valve timing for both inlet and exhaust camshafts. Charged intake air is cooled by two side-mounted intercoolers (SMIC)s. The engine is controlled by two Bosch DI-Motronic MED 9.1.2 engine control units, which act as 'master' and 'slave': two ECUs are required due to the high revs the engine can achieve. It also uses mapped direct ignition system with ten individual direct-acting spark coils, an electronic drive by wire throttle (Bosch "E-Gas"), cylinder-selective knock control, and cylinder bank adaptive lambda control, utilising eight lambda sensors.
