GM’s Opel/Vauxhall Insignia: 49 MPG Highway

When word slid over the transom that the Opel / Vauxhall Insignia had snatched the European Car of the Year (ECOTY) award from the Ford Fiesta by a single point, we had to go and do some digging.

Both the Insignia and Fiesta romped over the competition, with point tallies nearly 50% higher then the nearest competitor. It’s not hard to see why.

Mazda Diesels

While the mighty little Mazda3 has become quite popular here in the States, there’s forbidden fruit on the other side of the pond. Once again, we miss out on the most fuel-efficient models. It’s no secret that Mazda fits a number of thrifty diesel engines throughout its range in Europe, but American Mazda enthusiasts can only look longingly across the ocean in the hopes that one day those torque-filled penny pinching diesel power plants will find their way stateside.

The Mazda3 made a great impression this past summer, when we took it out on an extended highway run, round tripping to Washington DC. While our Mazda3 MPG review reveals highway fuel economy that far exceeds the official estimates, it can’t hold a candle to the remarkable numbers turned in by the Mazda3 diesel abroad.

Ready to get your blood boiling? We’ve done a bit of research to dig up England’s official estimates for the diesel-powered Mazda3, along with its stable mates …
