Mazda CX-5 gets AdBlue system to cut NOx

Mazda UK has updated the CX-5’s 2.2-litre diesel engines in line with the facelifted Mazda6, adding NOx-reducing Selective Catalytic Reduction (SCR) to its best-seller for the first time.

Since the 2.2-litre Skyactiv-D engine was introduced in 2012, Mazda has frequently highlighted its ability to meet Euro 6 emissions limits without need exhaust after-treatment. The CX-5 was also one of few diesel vehicles eligible to be sold in Japan.

SCR requires a urea-based additive to be injected into the exhaust emissions, converting harmful NOx emissions into diatomic nitrogen and water. In the CX-5, it will be accompanied by modifications to the injectors and combustion chamber to improve power delivery, alternations to the cooling system to shorten the inefficient warm-up phase, and a new two-stage turbo system.

The diesel engine will be offered in two power outputs; 150hp, which is available with front-wheel drive only but in all trim levels, and a new high-powered version which now produces 184hp and is offered exclusively in the range-topping SportNav+ trim, and with four-wheel drive. Both engines are available with manual or automatic transmissions.

Mazda has also adjusted the model range, adding an automatic gearbox to the 165hp 2.0-litre petrol engine, and increasing standard-fit safety equipment on all versions. The Sport Nav+ features a new head-up display projected onto the windscreen, and the CX-5’s first powered tailgate.

UK customers will be able to order the CX-5 from the end of August.
