Real-world MPG: economical 4x4s

  • Most efficient Ford Kuga added to database
  • Saloons from Audi, BMW and Mercedes tested
  • Results indicate real-world fuel economy

The What Car? True MPG team takes a range of new cars on a thorough road test every week, to bring you real-world MPG figures based on actual driving rather than a Government laboratory test.

We've recently added more economical 4x4s and stylish saloons to the database, with new models such as the Ford Kuga 2.0 TDCi 140 and the Mercedes CLA220 CDI being tested.

The 138bhp diesel Ford Kuga is the least powerful model in the range, but in most situations it doesn't feel appreciably slower. The official fuel economy figure for the car is 53.3mpg, but it achieved 42.0mpg in our tests – an 11.3mpg shortfall.

Earlier in the year we tested Kuga rivals from Honda and Mazda.

We tested the 148bhp Mazda CX-5 2.2 diesel with two-wheel drive, which claims average economy of 61.4mpg, but our True MPG technicians recorded 47.2mpg.

The four-wheel-drive Honda CR-V 2.2 i-DTEC came much closer to its official figure – it managed 47.6mpg, a deficit of only 2.8mpg.

The stylish Mercedes CLA220 CDI has also been tested recently. The official figure for this car with the seven-speed automatic gearbox is 62.8mpg, but we recorded 50.0mpg in our tests.

However, this result compares favourably with rivals'. The Audi A5 Sportback 2.0 TDI we tested earlier this year with the six-speed manual gearbox managed 48.5mpg (down 6.9mpg on official average economy).

One of the most efficient premium saloons we've tested is the BMW 320d. In Sport specification with the six-speed manual 'box, it was 6.6mpg below official figures on our test route, achieving an impressive average of 54.8mpg.
