2015 Mazda 2 diesel engine details revealed

The new 1.5-litre Skyactiv-D engine - which was first referenced in the Mazda Hazumi concept earlier this year (pictured above) - will be offered in the all-new Mazda 2 and will pump out 77kW of power at 4000rpm and 250Nm between 1500-2500rpm.

The engine is fitted with the brand's i-ELOOP brake energy regeneration system and engine stop-start, and doesn't require any nitrous-oxide after-treatment such as AdBlue. It features direct injection, a low compression ratio (14.8:1), a variable turbine geometry turbocharger and a water-cooled intercooler.

The 1.5-litre diesel can be teamed to either a manual or automatic transmission, both of which are expected to offer six ratios.

Mazda has not yet confirmed official fuel use for the new diesel 2, but the company has stated it will ensure the new model will "achieve among the highest level test mode fuel economy figures for a vehicle powered solely by combustion engine" in Japan.

Mazda Australia has previously suggested it wouldn't offer the new diesel-powered 2 city car in Australia due to a flagging demand for that type of engine in the most price-sensitive segment of the market.

The Japanese brand is pushing diesel in the 3 small car, however, releasing details of the new Astina XD turbo diesel which will go on sale locally in September.
