Another of the honorees in this year's International Engine
of the Year competition is BMW's
engine. The dual turbo 2.0L four cylinder that debuted in the 123d this year was selected by the 65 member jury as the Best New Engine for 2008. This new engine provides exceptional power for a 2.0L diesel and excellent fuel economy
. The 123d is rated at 204hp while achieving 45mpg on the EU driving cycle and emitting only 138g/km of CO2
. The engine uses a pair of turbochargers of different sizes to provide quick low end response and plenty of top end power. Features like an aluminum block have helped cut 38lbs from the weight of the engine compared to BMW's older four cylinder diesel. The performance and emissions of this engine are also enhanced by a third-generation common rail fuel injection system and particulate filter.
