What Car?’s technicians drive new cars every week to bring you our True MPG fuel economy data. Unlike official government figures generated by a laboratory test, the numbers we publish are gained from real-world conditions.
These are the most economical family hatchbacks you can buy at the moment, according to our tests. We've ranked petrols and diesels separately so you can decide which is better for you.
Most economical diesel family cars:
1. Honda Civic 1.6 i-DTEC – official 78.5mpg; True MPG 67.2mpg
The Civic with the 1.6-litre diesel engine is the most economical family car that our True MPG team has tested, returning an impressive 67.2mpg.
2. Seat Leon 1.6 TDI 110 Ecomotive Technology – official 85.6mpg; True MPG 63.2mpg
As with many cars on this list, it is the smallest diesel engine that is the most efficient in the Seat Leon range. We reckon the Ecomotive version is worth the extra cash over the standard 1.6-litre car.
3. Skoda Octavia 1.6 TDI 110 Greenline – official 88.3mpg; True MPG 61.9mpg
The Skoda Octavia is some way off its official figure of 88.3mpg, but a True MPG of 61.9mpg is still impressive especially considering the size of the car.
4. Peugeot 308 1.6 BlueHDI – official 88.3mpg; True MPG 60.8mpg
The Peugeot 308 isn't quite as good as its rivals but it does offer a stylish cabin, and with the 1.6-litre diesel engine installed it's cheap to run.
The A-Class is not the best premium hatchback you can buy, but one thing in its favour is a strong range of engines. This A200 version returned an impressive 59.6mpg, which is not far short of its official figure of 65.7mpg.
