BMW 1 Series Coupe and ConvertibleDecember 20, 2010
The BMW 1 Series Coupé and Convertible ranges have received some modifications that make them slightly more efficient.
ES, SE and Sport models now come with an Aero Curtain, which channels the airflow around the front of the car to reduce aerodynamic drag, thereby increasing efficiency.
Wheel arches are one of the main areas of aerodynamic drag and the Aero Curtain is BMW’s solution to reduce this inefficiency. Derived from race technology, air is routed into two ducts in the front apron which then flows out of a narrow opening at high speed in the wheelarch. This jet of air effectively covers the side of the front wheels like a curtain and thus reduces turbulence.
As a result, CO2 emissions have been slightly lowered throughout the range, with the 118d now rated at 118 g/km (1 g/km less than the previous 119 g/km), although fuel economy is unchanged at 62.8 mpg. All 2.0-litre petrol versions have CO2 emissions of 155 g/km or below.
As with all BMWs, the 1 Series Coupé and Convertible also come with a range of other EfficientDynamics measures: Auto Start-Stop is fitted to all petrol and diesel models (excluding versions with automatic transmission), while Diesel Particulate Filters, Brake Energy Regeneration, Electric Power Steering (excluding 135i), Intelligent Alternator Control and Optimum Shift Indicator for manual models are all standard throughout the range.
All BMW 1 Series Coupé and Convertible ES models come as standard with 16-inch alloy wheels, Dynamic Stability Control, Halogen headlights, MP3 playback capability and rear seat easy access system. Sport models have as standard 17-inch star-spoke alloy wheels, Sport multi-function leather steering wheel and front Sport seats – almost £1,200 worth of equipment that is currently offered for no additional cost over an ES model. SE models get rear Park Distance Control (PDC), front fog lights and automatic air conditioning with two-zone control.
All M Sport models, in addition to SE models, come with 17-inch light double-spoke style alloy wheels, door sill finishers with M designation, chrome front exterior trim, high-gloss Shadowline window surrounds, M aerodynamic bodystyling, M Sport suspension, Run-flat tyres, Sport seats and M Sport multi-function leather steering wheel.
BMW 135i M Sport versions add twin black-chrome exhaust tailpipes, a unique M aerodynamic package, M Sport suspension with 135i-specific calibration, hydraulic power-assisted steering, rear spoiler and up-rated high-performance braking system.
The new models differentiate themselves from previous incarnations by a new front bumper with redesigned fog lights and redesigned Halogen headlights with an ‘eyebrow’ element. When Xenon headlights are specified this ‘eyebrow element features an LED illuminated light bar.
The new BMW 1 Series Coupé and Convertible go on sale March 2011, with prices starting from £21,960 for the BMW 118d ES Coupé and £24,245 for the 118i ES Convertible.
