Check out this Smoked Topaz BMW 440i Convertible with M Performance Parts at the 2017 Detroit Auto Show. This perfectly showcases some of the parts at the BMW M Performance catalog.
Thanks to the BMW M Performance Power & Sound Kit bundled a valve controlled exhaust, it is able to achieve maximum performance and exhilaration. The new kit also features engine tuning software and an electronically controlled valve exhaust system that is actuated in Sport/Sport+ modes via the driving experience control button.
The power kit brings the total power output to 355 horsepower, a 35 hp increase over the stock engine. Torque is also increased to 369 lb-ft (+39 lb-ft) for automatic transmission vehicles and 355 lb-ft (+25 lb- ft) for manual transmission vehicles. The kit also provides faster acceleration: 0.2 seconds faster than the standard 340i/440i model from 0 to 60 mph.
The cabriolet looks stunning! It wears a set of new M Performance Wheels fully polished and available in 19 inches size, black kidney grilles, carbon fiber side mirror caps, M Performance Steering Wheel with a digital display and shifting indicators, a new center console in alcantara and surrounded by carbon fiber, carbon fiber DCT shifter, and aluminum pedals with the ///M branding.
