NEW FOR 2011:

– New 1 Series M Coupe
– 128i adds bi-xenon headlamps, Bluetooth connectivity, USB audio integration with iPod cable and BMW Assist with one-year Safety and Security subscription
– 135i adds new TwinPower Turbo six-cylinder engine; seven-speed double-clutch transmission replaces six-speed automatic

For 2011, the BMW 1 Series receives a new engine in the 135i, the TwinPower Turbo, which uses a single advanced twin-scroll turbocharger, along with a seven-speed double-clutch transmission in place of the previous six-speed automatic. Changes to the 128i include Bluetooth connectivity standard in all models, along with xenon headlamps for high and low beams, USB with iPod cable, and BMW Assist. A new high-performance M coupe is also added.

The 128i and 135i are available in coupe or cabriolet (convertible) configuration. Both use a 3.0-litre inline six-cylinder engine, which is naturally-aspirated in the 128i and turbocharged in the 135i. Both engines use a six-speed manual transmission that can be optioned to a six-speed automatic in the 128i and a seven-speed double-clutch transmission in the 135i. The 1 Series M Coupe uses a higher-performance version of the turbocharged 3.0-litre engine and comes exclusively with a six-speed manual transmission.

Features on the 128i Coupe include 17-inch alloy wheels, dual-zone automatic climate control, speed-sensitive power steering, automatic bi-xenon headlamps, adaptive brake lights, fog lights, heated mirrors, heated washer nozzles, rain-sensing wipers, tire pressure warning system, self-charging keyless remote, cruise control, leather-wrapped multifunction tilt and telescopic steering wheel, 60/40 split-folding rear seat with pass-through, power windows, leatherette six-way manually adjustable heated seats, Bluetooth connectivity, USB port, BMW Assist and CD/MP3 stereo.

The 128i Cabriolet adds driver and front passenger knee airbags, rollover protection, and fully automatic soft top. Its rear seat is fixed and includes a pass-through and transport bag.

The 135i models add 18-inch alloy wheels, sport suspension, performance brakes, adaptive headlights, xenon headlamps with washers, and M aerodynamic body kit.

The M adds 19-inch alloy wheels, bi-xenon headlamps, dynamic stability control with M Dynamic Mode, M-style spoiler, double twin tailpipes, heated black leather seats with contrasting orange stitching, door sills with chrome M, dynamic cruise control, and M-style steering wheel.
