Judged by a panel of 65 renowned motoring journalists from 32 countries, the IEOTY awards highlight and acknowledge engine engineering excellence.
Using their impressions from driving the latest cars, judges find powerplants that offer the best driveability, performance, economy, and refinement, and reward manufacturers for the successful application of advanced engine technology.

Best New Engine of 2008 went to BMW's 2.0L twin-turbo diesel (123d). Green Engine of the Year 2008 was awarded to Toyota 1.5L Hybrid Synergy Drive (Prius). But perhaps the most surprising was Nissan's absence from the ceremony, with rival Porsche stamping its authority on the awards. The new GT-R's motor was overlooked, in favour of the Porsche 3.6L Turbo (911 Turbo, 911 GT2), which picked up Best Performance Engine 2008.
