True MPG latest cars tested

The Dacia Sandero is the most efficient car we've tested in the last month, averaging 52.8mpg, while at the other end of the scale, the all-new Land Rover Discovery managed just 26.3mpg.

Of the cars we've tested previously, only the Mercedes S-Class Cabriolet performed worse than the Discovery.
