Siemens VDO has announced that for the first time an engine equipped with piezo direct injection gasoline (DIG) technology has featured in Ward's 10 Best Engine List of 2007. The 300 hp / 224 kW BMW 335i Twin Turbo 3-liter engine, which features Siemens VDO DIG technology, was unveiled at the Geneva Auto Show last year.
The piezo technology, in conjunction with advanced engine management systems, is credited for delivering higher torque and improved vehicle fuel economy. Direct injection fuel delivery, which is widely used in diesel engines, injects gasoline directly into the engine's combustion chamber, enabling the vehicle to start with less fuel, while simultaneously improving vehicle drivibility and emissions.
