BMW M235i Convertible is the pinnacle of the performance models available with the 2 Series Convertible. Like the M235i coupe, it features a higher-output M Performance TwinPower Turbo inline six, mated to either an 8-speed sport automatic or six-speed manual transmission. Aerodynamically optimized body features and custom chassis components are matched with typical M precision to the engine performance characteristics, ensuring a perfect blend of outstanding agility and precise handle.
A cooling system, engine management and engine sound tuning, all of which have been exclusively customized to the requirements of the BMW 2 Series M Performance models, complete the picture. Maximum power of 320 hp is generated between 5,800 and 6,000 rpm, from a displacement of 3.0 liters. The maximum torque of 330 lb-ft is available between 1,400 and 4,500 rpm. With the standard eight-speed Steptronic sport transmission with Launch Control function, the BMW M235i Convertible accelerates from 0-60 mph in 4.8 seconds.
It is also available with a six-speed manual gearbox with dry sump lubrication. Its short-throw action provides extra-sporty shifting. 60 mph is reached from a standstill in five seconds flat. Top speed is electronically limited to 250 km/h (155 mph).
In line with contemporary concerns, the BMW M Performance models incorporate an extensive range of BMW EfficientDynamics technologies. US EPA numbers are not yet available for the M235i Convertible, however the M235i Coupe boosts a near 20 percent improvement over its 135i Coupe predecessor.
