Mazda CX-7 now has diesel power

Mazda has announced a revised version of its CX-7 4×4, featuring the latest Mazda ‘family face’ and a new, fuel-efficient diesel engine.

The Mazda CX-7 has always been a funny beast. In its current form it is only available with a 2.3-litre turbo petrol engine – not exactly parsimonious when paired up to a mid-sized four-wheel drive SUV. But as a budget alternative to a BMW X5 it is certainly good to drive.

Fortunately, mid-life revisions to its exterior design set to be unveiled at the in September are accompanied by the long-awaited introduction of an efficiency-improving diesel engine. This should see the CX-7 go from environmental offender to green goddess in one fell swoop.

CX-7 gets cleaner diesel 

Mazda’s recently introduced 2.2-litre turbodiesel provides the motive power. But boosting this already eco-friendly unit still further, the new CX-7 diesel will become the first passenger car from any Japanese manufacturer to be fitted with a Selective Catalytic Reduction (SCR) system.

SCR works by injecting an additive – AdBlue – into the exhaust gases in order to reduce nitrogen oxide (NOx) emissions. NOx emissions are particularly concerning for diesel engines, and directly responsible for environmental damage such as acid rain. They are already subject to severe restriction in the United States; European legislation will surely follow.

New Mazda face for CX-7

Mazda’s SCR system is compact, so the CX-7 retains its entire 455-litre luggage space. The AdBlue will be renewed during routine servicing and requires no additional buyer maintenance. The 2.2-litre diesel is also Euro Stage V emissions compliant.

Looks-wise, the new CX-7 gets the latest Mazda smiley face already seen on the and . Full details – including performance and efficiency data – are yet to be confirmed, but it seems the turbodiesel may well spell the end for the turbo petrol CX-7.
