The Mazda3 Revealed | Part Four

The four Mazda3 powertrains combine Mazda's typical Zoom-Zoom driving experience with excellent environmental performance to provide exhilarating driving.

The new Mazda3 engine line up has been tailored for European customers and now includes the newly developed MZR-CD 2.2-litre turbo diesel engine, carried over from the all-new Mazda6, in addition to the petrol MZR-1.6-litre and 2.0-litre (now with the option of a 5-speed Activematic transmission), and the MZ-CD 1.6-litre turbo diesel.

A high-performance clean diesel engine with top class output, fuel economy and refinement, the 2.2-litre engine will be offered in two variants, a high power version with a maximum torque of 400 Nm at 1,800-3,000 rpm and an output of 185 PS at 3500 rpm, and a standard power version with a maximum torque of 360 Nm at 1,800-2,600 rpm and an output of 150 PS at 3500 rpm.

Both versions have outstanding clean emissions performance, comply with the Euro Stage 5 regulations and feature a Mazda developed unique Diesel Particulate Filter (DPF) technology for more efficient regeneration.  Fuel economy is also greatly improved by 7 to 10 per cent (compared to the MZR-CD 2.0-litre engine in the previous model), attaining 5.4 l/100 km for the standard power version and 5.6 l/100 km for the high power version.

Mazda's petrol engine underfloor catalyst is the world's first vehicle catalyst to be constructed with single nanotechnology, which controls even finer materials structures than nanotechnology. It is used to embed individual particles of precious metals, which are less than 5 nanometers in diameter, into the catalyst base material. This new development enables Mazda to reduce the amount of expensive precious metals such as platinum and palladium by 70 to 90 per cent without impairing catalyst performance. This new catalyst is an important part of Mazda's efforts to reduce reliance on limited resources.
