What Car? True MPG is helping more car buyers than ever to find out the fuel economy they can really expect from their new car – and we're testing more models each day.

Cars tested range from cheap city cars, such as the Fiat Panda, to luxury saloons like the Porsche Panamera. If the model you're interested in wasn't listed the previous time you looked, it's well worth revisiting True MPG now.

We've just tested the Mazda CX-5 2.0 Skyactiv-G 2WD, which returned an impressive average economy of 41.3mpg. That's 5.7mpg down on the official figure of 47.0mpg, but only 5.9mpg less than the 2.2 Skyactiv-D 2WD diesel model, which achieved 13.2mpg less than its official figure.

Another compact SUV that we've just tested is the Kia Sportage. The 2.0 CRDi 134 auto came exceptionally close to matching its 40.0mpg official figure, with a real-world average of 39.1mpg.

Large diesel engines tend to perform well in our tests, but the Audi A6 Avant 3.0 TDI 204 Multitronic didn't follow this trend. Although its True MPG average of 42.7mpg is respectable, it is considerably down on the car's official figure of 54.0mpg.

The BMW 520d Touring auto is another executive estate that we've recently tested. It averaged 48.2mpg – an impressive figure for such a large car, although not quite a match for the 55.0mpg official figure.

Audi A6 Avant 3.0 TDI 204 Multitronic achieved a respectable 42.7mpg, but was some way short of its official figure

A large car with a four-cylinder diesel that performed even better was the Skoda Superb 1.6 TDI CR. Its True MPG average of 53.1mpg is just 2.9mpg short of the official figure, which makes it one of the most fuel-efficient cars in its class.

The Ford Focus 1.0 Ecoboost offers the performance of a petrol with the fuel economy of a diesel, according to an official average economy of 56.5mpg. Unfortunately, our testers found the Focus fell some way short of this, with a True MPG figure of just 38.2mpg.

On paper, the most economical Volvo V40 is the 1.6-litre diesel D2, with an official average of 78.5mpg. However, our True MPG testers found it returned a less impressive 56.8mpg.

Most MPVs are bought with diesel engines, but Renault offers a 1.2 TCe petrol in its Scenic, complete with official fuel economy of 48.0mpg. Our True MPG tests revealed it was not as impressive in real-world driving, with an average of 36.6mpg.

Most won't buy the Mini Coupe Cooper S for its fuel-saving abilities, but the small two-seater still claims an impressive official average of 48.8mpg. It didn't quite reach those highs on our tests, but it achieved a decent 40.2mpg.

The Fiat Panda 1.2-litre petrol is one of the cheapest city cars to buy, and it also promises to be cheap to run – thanks to an official average economy 54.3mpg. Our True MPG tests revealed a figure of 43.1mpg.
