    BMW hosted the world premiere of the convertible version of the high-performance M3 at the Geneva motor show but the vast majority of the BMW stand is devoted to examples of BMW’s EfficientDynamics initiative for the reduction of fuel consumption, CO2 and emissions.

     

    The M3 Convertible is the third addition to the M3 lineup alongside the M3 Coupe and the M3 sedan. Like the new 3-Series Convertible, the M3 is offered for the first time with a power-retractable three-piece hardtop that provides excellent noise management when closed and automatically stows in the rear compartment during open air driving.

     

    The M3 Convertible is powered by the 420-horsepower 4.0-liter high-speed V8 developed specifically for the model range. The Convertible shares the aggressive styling of the coupe and sedan including the powerdome hood with two openings, the functional design of the front and rear dams, fender grilles carried-over from the coupe and light alloy wheels. The suspension is based on the technology in the M3 Coupe specifically tuned to accommodate the weight of the roof system.

     

    BMW Vision EfficientDynamics

    Based on the X5 Sport Activity Vehicle, BMW also revealed the concept vehicle named “BMW Vision EfficientDynamics” to showcase emerging technology that will further contribute to its environmental strategy.

     

    Produced as a study of how a large Sport Activity Vehicle can reach consumption levels more typical of a small compact car, the concept is powered by a hybrid system that combines a 2.0-liter four-cylinder diesel engine and a 15 kW (20 horsepower) electric motor. The Vision Efficient Dynamics achieves fuel economy of 6.5 liters per 100 km (approx. 36 mpg) with only 172 grams per kilometer of carbon emissions. With Variable Twin Turbo technology the diesel engine produces 204 horsepower, making it the first diesel with power output of more than 100 horsepower per liter.

    Another component of the powertrain is an all-new extremely fast and efficient eight-speed automatic transmission developed with partner ZF.

     

    A high-performance lithium-ion battery stores electricity to power the electric motor while the roof contains a solar panel that generates energy for pre-heating the transmission fluid for more efficient cold starts. Aerodynamics have been improved including a new wheel design that minimizes turbulence.

     

    The Vision EfficientDynamics will not be produced anytime soon, but individual elements will become available on different BMW models to reduce fuel consumption. BMW, in cooperation with Mercedes-Benz is developing a modular system of hybrid components that each manufacturer can use to install in a variety of vehicles.

     

    1-Series Convertible

    BMW used Geneva for the European unveiling of its 1-Series Convertible that debuted at the North American International Auto Show in Detroit in January.

     

    For the European market the 1-Series Convertible is the fourth version in the model line joining the five-door, three-door and Coupe. A range of engines will be offered including a 306 horsepower 3.0-liter twin-turbo six-cylinder the direct gasoline injection (135i), a 218 horsepower 6-cylinder (125i), a 170 horsepower four-cylinder (120i), a 143 horsepower four-cylinder (118i) and a new-generation 177 horsepower four-cylinder diesel (120d).
