Mazda will launch a version of the AdBlue system used on commercial vehicles to reduce nitrogen oxide emissions in the facelifted Mazda CX-7.
The technology involves injecting aqueous urea into the exhaust to help neutralise nitrogen oxide; it’s called selective catalytic reduction (SCR).
Mazda claims to have reduced the size of the components to make them more suitable for passenger cars, although Mercedes Benz now offers SCR on the new E-class and has fitted it to the GL and ML since last year.
The SCR technology will be available in the CX-7 with the firm’s 2.2-litre four-cylinder diesel engine later this year, making Mazda the first Japanese car maker to offer SCR.
