The rear-wheel drive 128i is available as either a coupe or convertible. The 128i is powered by a 230-hp 3.0-liter dual overhead cam, inline six-cylinder engine mated to either a six-speed manual transmission or a six-speed automatic with steering wheel paddle shifting. Standard safety features include six airbags on the coupe, four on the convertible, anti-lock brakes, adaptive brake lights, stability and traction control and run-flat tires with pressure monitoring. The 128i features the usual BMW creature comforts such as a high-definition audio system, auxiliary input jack, automatic climate control, leather wrapped steering wheel and multi-way adjustable front seats. For 2012, the headlights and taillights have been redesigned. The front bumper is new and features BMW's innovative air curtain system.
