What Car?’s technicians drive new cars every week to capture 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.
This week we are looking at an ever-growing group of cars – crossovers. The recently launched Citroen C4 Cactus is the latest of this bunch, so we've turned the focus on petrol cars as a result. Here are the five cars that have beaten 40mpg in our real-world tests so far.
1. Citroen C4 Cactus 1.2 PureTech 100 - offical 60.1mpg: True MPG 50.0mpg
The C4 Cactus is not only following the relatively recent crossover trend, but it also follows Dacia's lead in taking motoring back to basics. It does without a lot of the luxuries that buyers at this level of the market might not be too fussed about, like rear electric windows and split-folding rear seats.
One benefit is cost-saving, but it also cuts out a load of weight, which helps with economy. This means it is the most efficient of the petrol crossovers that we have tested, with a True MPG figure of 50.0mpg.
2. Mazda CX-5 2.0 Skyactiv-G 2WD - official mpg 47.1mpg: True MPG 47.1mpg
The Mazda CX-5 is one of the larger cars on this list, but it is also one of the most efficient, even with a comparatively large 2.0-litre petrol engine. This is also the cheapest way to get into a CX-5, and it is cleaner in terms of CO2 than many of its diesel rivals, which is a real plus.
If you are after a CX-5, though, then the diesel models are a better all-round bet.
3. Nissan Juke 1.2 DIG-T - official mpg 47.1mpg: True MPG 40.6mpg
Nissan gave the small Juke a comprehensive facelift recently, and the car now has revised looks, more boot space, increased personalisation and this new 1.2 turbocharged petrol engine.
The engine brings a touch more around-town peppiness, and makes the Juke slightly quieter on the move than before. It is also, on the basis of our True MPG tests, an economical car to run as well. There is more to consider with the Juke, though, and its small cabin and harsh ride are other factors to consider.
4. Nissan Qashqai 1.2 DIG-T - official mpg 50.4mpg: True MPG 40.4mpg
The Nissan Qashqai gets the same turbocharged petrol engine as the Nissan Juke, and it is almost as efficient in the larger car, with a True MPG rating of 40.4mpg.
There is plenty to love about the new Qashqai, and we named it the What Car? Car of the Year at the start of 2014. It remains the best in its class.
5. Peugeot 2008 1.2 82 - official mpg 57.6mpg: True MPG 40.3mpg
The final car that makes it over the 40mpg mark - the Peugeot 2008 - is another one that is best suited to town driving. It isn't particularly quick and is noisy when you put your foot down, but it is certainly good on fuel, with a True MPG rating of 40.3mpg.
