True MPG: most and least efficient family cars
What Car?'s True MPG tests show what fuel economy you can really expect from a car. Here, we reveal the best and worst performing family hatchbacks...
1. Vauxhall Astra 1.6 CDTi 110 Ecoflex
True MPG 56.3mpg
This version of the Vauxhall Astra is the most efficient family car we've ever tested, averaging an impressive 46.4mpg in town and more than 73mpg on rural roads. If fuel economy is your top priority, but you also want good comfort, lots of equipment and a very reasonably purchase price, look no further.
The least fuel efficient family car
Volkswagen Golf GTE
True MPG 34.1mpg
While the 1.0-litre petrol Golf is frugal enough to take 6th place on this list, the GTE plug-in hybrid finishes rock bottom. However, this isn't as bad a result as it first appears; as with the Ioniq, the GTE's batteries were flat at the start of the test, so it simply highlights how important it is to keep the batteries topped up if you buy a plug-in hybrid. If the idea of getting the cable out of the boot at the end of each journey doesn't appeal, you'd be better of with a conventional hybrid, a diesel or a small-capacity petrol.
