Mazda CX-7 diesel

The missing piece of the CX-7 SUV jigsaw is on show here in Geneva in the form of a 2.2-litre diesel engine.

The success of the car was always going to be tainted by the fact it has been available with only petrol power.

Now, though, the car has a 170bhp 2.2-litre common-rail diesel unit, which is capable of powering the car from 0-62mph in 11.3 seconds and on to a top speed of 124mph. CO2 emissions are 199g/km.

The arrival of the diesel engine coincides with a mild 'blink-and-you've-missed-it' facelift for the SUV. The Mazda logo on the grille is bigger and the rear roof spoiler is also larger - and that's about it.

Prices have yet to be confirmed for the diesel, but expect to see the car on sale in the UK by the end of this year.
