The 2009 L.A. Auto Show got even more interesting. The BMW Vision EfficientDynamics Concept will make its North American debut at the “green motor show”.

One of the most highly acclaimed BMW concepts will debut next Wednesday during the press days. BMW Vision EfficientDynamics is the latest implementation of the EfficientDynamics philosophy. The hybrid powertrain provides a top speed limited electronically to 155 mph, with acceleration to 62mph (100 km/h) in 4.8 seconds.

The power and performance are made possible by combining a fuel-efficient 1.5 liter 3-cylinder turbodiesel with one electric motor on each axle. The intelligent combination of these units, together with precisely controlled energy management, simultaneously enhances the dynamic performance and the efficiency of the car. Overall system output is 356 horsepower, and peak torque is 590 lb-ft.

BMW Vision Concept L.A. Auto ShowThe 3-cylinder diesel engine fits conveniently in front of the rear axle like in an agile mid-engine sports car. Fuel is injected by the latest generation of High Precision Direct Injection, and the turbocharger features variable intake geometry for maximum efficiency. Engine output is 163 hp with peak torque of 214 lb-ft.

The engine is supplemented by two electric motors. The compact electric motor positioned between the diesel engine and the DCT outputs a consistent 33 horsepower and is able to reach a peak of up to 51 hp. Maximum torque for the rear electric motor is 214 lb-ft.

A second electric motor acts on the front axle. This engine, a hybrid synchronous motor, offers continuous output of 80 horsepower and peak torque of 162 lb-ft. Extra power of 112 horsepower is available for a period of up to 30 seconds, and, for a 10-second “burst,” the electric motor is able to develop 139 horsepower. The power is transmitted through a 2-stage, single-speed reduction gearbox.

The specific output of 109 hp per liter sets a new benchmark in diesel technology. The power delivered by the turbodiesel is conveyed to the rear axle by means of a double-clutch transmission (DCT)

Average fuel consumption in the EU test cycle is 3.76 liters/100 kilometers (62.6 mpg), and the CO2 emission rating is 99 grams per kilometer.

The chassis and suspension of BMW Vision EfficientDynamics are made completely of aluminum; the roof and the outer skin on the doors are made almost completely of a special polycarbonate glass automatically darkening as a function of the light shining on the car. Measuring 181.1″ in length, 74.8″ in width and 48.8″ in height, this unique concept car offers ample space for up to four passengers and their luggage. Thanks to the consistent lightweight construction strategy applied on the car, curb weight is 3,076 lb.

In the design of the interior, BMW uses an innovative layering technology.

As always, we’ll return with more information.
