More than 5,400 BMW 1 Series have been sold in Australia since its introduction in 2004.

Now, a new-look BMW 1 Series adds a bolder appearance, improved performance and economy.

Running changes to the 1 Series range include a turbo diesel engine with an aluminium powerplant that increases power output in the 120d by 10 kW and peak torque by a further 10 Nm, lowering acceleration times while adding to the fuel economy.

With no less than 340 Nm of torque and a maximum power output of 125 kW, the 120d accelerates from zero to 100 km/h in 7.8 seconds (previously 8.5 seconds) and returns a combined fuel consumption figure of 6.1 litres/100 kilometres.

The new BMW 1 Series is identified by a more dominant BMW kidney grille flanked by clear-glass headlights that are integrated into the bumpers and a wider intake in the newly designed front air dam.

A daytime running lights option, utilising corona rings surrounding the headlights, is incorporated into a new bi-xenon headlight package, while BMW adaptive headlights, which provide optimum illumination on winding roads, are also an option.

From the rear, the new BMW 1 Series is identified by modifications to the design of the fog lights, tail lights – with new two-stage brake lights – and the bumper.

Inside, the BMW 1 Series gains new, higher-quality materials and colour choices as well as additional storage spaces.

BMW 1 Series owners also benefit from the availability of a new USB interface option to supplement the standard AUX plug and allow the integration of an external MP3 player.

New colours – Montego Blue and Patagonia Green – are also available in the new 1 Series, while new-look alloy wheels are available for 118i, 120i and 120d models.

The new BMW 1 Series 3-door models will not be available in Australia. Audi dealers may be scratching their heads, but, no doubt, will be doing so with a smile on their faces.
