A jury of automotive journalists has selected the best engine in the world, and just like last year, it's a Bimmer. Edmunds Inside Line explains, "BMW's 3.0-liter twin-turbo engine won the top prize in the 2008 International Engine of the Year competition on Wednesday, besting such rivals as the Porsche turbocharged 3.6-liter engine that powers the 911 Turbo." If you want to own the world's best engine, you'll have to buy a BMW X6 (though only the xDriv35i has the award-winning inline-six), a 135i or a 335i. BMW also won the award for Best New Engine of the Year, for a 2.0-liter diesel twin-turbo that you can't buy in the U.S. Green Engine of the Year went to the 1.5-liter Hybrid Synergy Drive that powers the Toyota Prius.
The winners were chosen by a panel of 65 auto journalists from 32 countries. The full list of winners can be found in a press release from the organization. No U.S. automakers claimed a prize this year. BMW brought home five, Toyota and VW/Audi each won two, and Subaru and Porsche claimed one each.
Motor Trend notes that "The judges heavily favored forced-induction engines, with just four of the winning engines being naturally aspirated, one of those being a hybrid."
In fact, environmental considerations clearly weighed into the final tally. Explaining their reasoning, the judges themselves noted that the winner was "one of seven engines to triumph in the 2008 Awards that use turbocharging to achieve high power output from smaller displacement engines that use less fuel and produce less CO2."
