Summer might be coming to a close but that hasn't stopped Daehler from introducing their new tuning program for the BMW M235i Convertible.

Starting under the hood, the 3.0-liter TwinPower Turbo six-cylinder engine has been tuned to produce 390 PS (287 kW). This enables the all-wheel drive variant to accelerate from 0-100 km/h in 4.2 seconds before hitting a top speed of 288 km/h (179 mph).

The car can also be equipped with an adjustable coilover suspension , a stainless steel sports exhaust system and a variety of aftermarket wheels.  Interior changes are limited but the company offers premium leather and Alcantara upholstery as well as an "MID" display that shows additional vehicle information.
