Mazda3 updated with SkyActiv-G engine and exterior tweaks

The Mazda3 has been long criticised for its heavy fuel use but all that is now set to change with Mazda’s new SkyActiv-G petrol engine.

The 2012 Mazda3 has just made its debut at the 2011 New York Auto Show and is the first production use for the all-new 2.0 litre four-cylinder SkyActiv-G petrol engine.

The new motor will combine with the Skyactiv-MT six-speed manual transmission and the SkyActiv-Drive six-speed auto to chase down better fuel economy.

To achieve greater efficiency the SkyActiv-G engine uses multi-hole injectors and a higher compression ratio of 12.0:1. Power hasn’t decreased but has been bumped up to 115kW from 108kW for its predecessor, and torque has increased from 182Nm to a round 200Nm.

The new fuel consumption figures when paired with the SkyActiv-MT manual transmission is listed at 8.7 l/100km for urban driving and 6.0 l/100km on the motorway. The current MZR 2.0 litre petrol engine is quoted at 10.8 and 6.2 l/100km respectively, when combined with a six-speed manual transmission.

Using the SkyActiv-Drive six-speed automatic transmission, the new petrol engine returns 8.4 l/100km in the city and 5.8 l/100km during motorway cruising. In its current five-speed auto form, the MZR 2.0 litre engine returns 11.3 and 6.3 l/100km respectively.

In addition to the newly-efficient drivetrains, the 2012 Mazda3 also shows off an updated exterior. At the front there are redesigned headlights and a reworked fascia with a new grille that tones down the car’s trademark grin. The rears of both the sedan and hatch have also received some subtle updating.
