The BMW 1-Series coupe and convertible have recieved some minor styling updates, while fuel economy and emissions have been improved.
The major change comes in the form of an 'aero curtain', now fitted to ES, SE and Sport models. This channels airflow around the underside of the car, reducing drag.
As a result emissions have been lowered, and fuel economy improved, on the majority of models - although the 2.5-litre and 3.5-litre engines remain unchanged. The 118d coupe is now rated at 118g/km of CO2, down from 119g/km, meaning company car tax remains unchanged. However, fuel economy is improved and the car now claims an average of 62.8mpg.
Both models feature a new front bumper with redesigned fog lights and updated headlights. The rear headlights have also been tweaked for a more detailed appearance.
The 1-Series comes with a range of other economy and emissions improving equipment. Most models are equipped with exhaust filtration systems, brake energy regeneration, electronic power steering, intelligent alternator control and an optimum shift indicator for manual models. Manual cars also feature an automatic Start-Stop system.
All ES models come with alloy wheels, stability control, halogen headlights and iPod connectivity. Sport models get bigger alloys, a sports steering wheel with mounted controls and front sport seats. For those who need a little more, SE models add rear parking sensors, front fog lights and dual-zone climate control.
The top-specification M Sport models, in addition to the SE specification, feature different alloy wheels, chrome front exterior trim, sports suspension and seats, black window surrounds and M Sport sill trims, body styling and a multi-function leather steering wheel. Run-flat tyres are also fitted. 135i M Sport versions also get twin black-chrome exhaust tailpipes, a unique aerodynamic package, hydraulic power steering, a rear spoiler and uprated brakes.
