Frankfurt Auto Show: BMW Vision EfficientDynamics Concept Page 2

Follow Marty

Dimensions place the EfficientDynamics concept in the middle of BMW's current coupe range. It measures 181.1 inches long, 74.8 inches wide, and 48.8 inches tall, and weighs 3076 pounds. The concept has 5.3 cubic feet of luggage space, enough for two golf bags.

The body of the Vision concept is lightweight in design and execution, its engineers say. The body shell and suspension are rendered in aluminum, the roof and door skins are formed from polycarbonate glass that darkens automatically in response to climate--like photochromic glasses. The cockpit of the Vision concept also uses lightweight materials. Kevlar frames the seats, and connects them to the center console, but elsewhere, sustainability is penned into the colors and materials chosen. LED lighting inside has ambient hues, while the headlights and taillights are linked to the ambient lighting to shift its color and intensity, depending on exterior conditions. A head-up display and night vision are configured into the gauges and driver displays.

Sophisticated software underpins virtually every system of the concept. That software takes constant readings from the car's systems and interprets the data to enable more efficient operation. BMW says, for example, the navigation system's traffic data can cue the drivetrain to shut down the concept's cooling fans to prepare it for more efficient highway operation. Even the air conditioning and electric power-steering sensitivity are constantly tweaked in this way for optimum performance, BMW says.

In tandem with the EfficientDynamics concept, BMW is also displaying its production X6 ActiveHybrid and 7-Series ActiveHybrid at the Frankfurt auto show.
