True MPG: 66 more cars tested
* 66 models added to True MPG database * Check our results before you buy a new car * Results indicate real-world fuel economy...
The What Car? True MPG real-world fuel economy database has been expanded to include another 66 new cars.
Unlike the laboratory-derived Government figures, True MPG data is gained through testing in real-world conditions, to bring you realistic MPG figures.
From next week, youll see regular updates from here to let you know which cars weve tested and how they performed.
The biggest gap we recorded between official and True MPG was the Vauxhall Corsa 1.3 CDTi Ecoflex. Despite a claimed 85.6mpg, we measured a figure of 61.4mpg. However, the Corsa was still the most economical car we tested in the same time period.
This impressive result was closely followed by that of the Renault Clio 1.5 dCi 90, which did 60.1mpg.
In the past four months only one car beat its claimed MPG figure. The Suzuki Swift 1.2 SZL achieved 51.7mpg 1.7mpg above what Suzuki officially quotes.
Finally, the Toyota Aygo 1.0 VVT-i was measured at 57.0mpg, making it the most efficient petrol car weve recorded so far.
