London: A new study has revealed that some diesel cars are giving the much-hyped hybrids a run for their money when it comes to fuel efficiency.
According to the Which Study, Toyota`s petrol-electric Prius that kick-started the fashion for hybrids a decade ago, achieved fewer miles to the gallon than a sporty BMW 3-series diesel, reports the Daily Mail.
The latest edition of Which Car looked at the actual fuel efficiency achieved in ``real world`` driving rather than the claims made by the manufacturers.
This showed that in its tests a BMW 320Ed small executive saloon managed 64.2 miles to the gallon - ahead of the Prius`s 61.4mpg.
Over a year`s driving of 12,000 miles, the BMW will cost 1,120 pounds - or 51 pounds less than the Prius at 1,171 pounds.
“In most cases you`ll save money with a hybrid. Fuel costs are low and they save drivers on tax, not to mention lower emissions.
However, they`re not always more fuel-efficient than advanced diesel engines,” the study said.
“Which Cart has found that a diesel BMW 320Ed (fuel costs for 1 year or 12,000 miles: 1,120 pounds) would cost you less at the pumps than a Toyota Prius (1,171 pounds).
“BMW may have a reputation for making aggressive, sporty saloons, but the 320Ed (Efficient Dynamics) makes an impressive statement about BMW`s clever fuel-saving technology,” it added.
