Diesel engine outperforms hybrid in German test

| 8/24/2005

A test run by German magazine Auto Bild found that an advanced diesel engine in a Mercedes-Benz SUV was more fuel efficient than a gas/electric hybrid engine in a Lexus SUV.

The vehicles were driven from New York to San Francisco and the diesel engine had a highway fuel consumption rate of about 2 gallons every 100 kilometers, which is about 62 miles. The hybrid consumed about 2.2 gallons per every 100 kilometers. In other words, the diesel got about 31 miles per gallon, while the hybrid got about 28.

However, the test showed that the diesel was slightly less fuel efficient than the hybrid in city driving.
