Half of all engine classes in the 2010 International Engine of the Year Awards were won by the BMW Group.
Since the awards' inception in 1999, the BMW Group products have been honored with more than 50 class and overall victories.
The winners of the "International Engine of the Year" awards are decided by a global jury made up of 76 journalists from 35 countries.
Winner: 1.4-1.8 liter class:
This is the fourth year in a row that the 1.6-liter four-cylinder Mini engine has won, although it has already been succeeded by an even more impressive unit. In addition to the turbocharger and direct injection system of this award-winning model, the new engine also has variable valve control. In the Mini Cooper S, this unit produces 184hp, yet the official combined fuel consumption is 40.5mpg.
Winner: 1.8-2.0 liter class:
The winning 2.0-liter four-cylinder BMW diesel features an aluminum direct injection power unit with turbochargers and common-rail direct injection. Its output is 204hp and impressed jury members with its pulling power and outstanding efficiency. The experts commented that in view of the qualities of this engine, which is offered on 1 Series and X1, it was doubtful diesel engines will get any better in future. Winner: 2.5-3.0 liter class:
Such is BMW's dominance in this category, the 3.0-liter in-line six-cylinder engine has replaced its predecessor, which was also overall International Engine of the Year in 2007 and 2008.
The new 306hp unit comes with BMW's new twin-scroll single turbocharger and High Precision Direct Injection and Valvetronic systems. It is featured in cars such as the 135i Coupe and 535i.
Its diesel equivalent, the new 3.0-liter in-line six-cylinder diesel with twin turbochargers and common-rail direct injection came second in the class.
Winner: 3.0-4.0 liter class:
For the third year running, the 420hp 4.0-liter V8 in the M3 family came top of the judges' polling. The panel noted that in addition to brilliant performance, they were impressed with the efficiency of the engine, which is combined with an Auto Start/Stop function, brake energy regeneration and other BMW EfficientDynamics measures in Europe.
