What Car?’s technicians drive new cars every week to bring you 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’re looking at two new models of the Citroen Grand C4 Picasso, as well as the latest version of the Vauxhall Zafira Tourer. The three MPVs all have diesel engines and six-speed manual gearboxes, and all beat 50mpg in our test.

1. Citroen Grand C4 Picasso 1.6 e-HDi – official 70.6mpg: True MPG 54.4mpg

The latest Grand C4 Picasso is a supremely practical seven-seater. All-round visibility is outstanding and the passenger seats fold and slide in almost every way you could imagine. The dashboard looks like it belongs in a more expensive car, too. This 113bhp version is powerful enough even with seven people on board, which is why it’s our pick of the range.

2. Vauxhall Zafira Tourer 1.6 CDTi Ecoflex – official 68.9mpg: True MPG 51.5mpg

The Zafira Tourer is roomy, good to drive and won’t cost the earth to run. True, the Alhambra is more spacious, but it’s also considerably more expensive. Vauxhall’s new diesel engine is so good that it helped the car win a group test against seven-seater rivals in the January 2014 edition of What Car? magazine. It’s more economical, less polluting, smoother and quieter than any other Vauxhall diesel we’ve driven.

3. Citroen Grand C4 Picasso 2.0 Blue HDi – official 65.7mpg: True MPG 50.1mpg

You might be tempted by this Grand C4 Picasso because of the extra power over the 1.6 e-HDi. We’ll don’t think it’s worth spending the extra, though; the smaller engine is still flexible enough, and this 2.0-litre diesel doesn’t feel or sound any more refined. It won’t cost you much less than our favourite Alhambra to buy or run, and the Seat is still the better car.
