BMW's Vision EfficientDynamics


BMW Vision EfficientDynamics

BMW sees technical innovations reducing both emissions and fuel consumption as an elementary part of the brand’s product strategy, just like vehicle concepts enhancing the Sheer Driving Pleasure so typical of BMW as a lasting, sustained experience.

Now the BMW Vision EfficientDynamics concept car clearly demonstrates that these objectives expressed through the BMW EfficientDynamics development strategy are fully compatible with the most demanding reduction in fuel consumption and emissions complying in full with future requirements.

Conceived as a 2+2-seater with plug-in full-hybrid technology, this unique car is able to combine the performance of a BMW M Car with a standard of fuel economy and emission management exceeding even the current level achieved by the latest small cars in the market.

This outstanding result is made possible by the consistent integration of BMW ActiveHybrid components, their combination with an extremely economical combustion engine, and the outstanding aerodynamic qualities of the BMW Vision EfficientDynamics concept car.

BMW Vision EfficientDynamics is the result of an all-inclusive development process starting from a clean sheet of paper. This ensures an improvement of both efficiency and driving pleasure far exceeding the sum total of all individual components and technologies, and is also borne out in the very emotional design of this unique concept car. BMW Vision EfficientDynamics is therefore an unprecedented sports car offering fascinating perspectives for the future of Sheer Driving Pleasure combined in full harmony with maximum efficiency.

Presenting this unique concept car, BMW is once again demonstrating the company’s outstanding competence in the development of cutting-edge drive systems. Indeed, BMW Vision EfficientDynamics is the most comprehensive implementation of the BMW EfficientDynamics development strategy seen so far.

The drive units provide a top speed limited electronically of 250 km/h or 155 mph, with acceleration to 100 km/h in 4.8 seconds. Average fuel consumption in the EU test cycle is 3.76 litres/100 kilometers, equal to 75.1 mpg imp, and the CO2 emission rating is 99 grams per kilometer.

CO2 emission management is even more outstanding when driving in the all-electric mode after charging the battery from a plug-in source: Taking all emissions in the generation of electricity into account, as prescribed by the EU mix, the car’s emission rating in this case is just 50 grams per kilometer.

Through this unique balance of driving pleasure and fuel economy the BMW Vision EfficientDynamics concept car clearly demonstrates the potential of BMW ActiveHybrid technology making its world debut at the 2009 Frankfurt Motor Show in the BMW ActiveHybrid X6 and BMW ActiveHybrid 7 production models.

This truly impressive power and performance is made possible by combining a particularly fuel-efficient three-cylinder turbodiesel with one electric motor each on the front and rear axle.

The intelligent combination of these three power units and the energy they develop, together with precisely controlled energy management, serves to enhance both the dynamic performance and the all-round efficiency of the car, using the full potential of BMW ActiveHybrid to reduce both fuel consumption and CO2 emissions to the greatest possible extent. Overall system output is 262 kW/356 hp, peak torque is 800 Newtonmetres/ 590 lb-ft.

The special arrangement of the three power units allows all-wheel drive also available in the all-electric mode. The result is minimum power loss and at the same time harmonious transmission of the power available under all conditions.

In its design, BMW Vision EfficientDynamics for the first time conveys the dynamic look so typical of a BMW sports car to a hybrid vehicle. Developed with know-how from Formula 1, the body of this unique sports car is an expression of intelligent lightweight technology and supreme aerodynamic efficiency.

And in the design of the interior, the focus was likewise on both the fascinating driving experience and, in particular, on transparent, hands-on technology and maximum reduction of weight.

• High-performance concept study with BMW ActiveHybrid technology visualising the dynamic performance typical of a BMW against the backdrop of future demands in sustained mobility. BMW Vision EfficientDynamics as a symbol for the future of Sheer Driving Pleasure in harmony with trendsetting efficiency.

• Development aim: The performance of a BMW M Car and a highly emotional character combined with the fuel economy and emission management of a modern small car in the premium class. As a result, this unique sports car offers the most consistent rendition of the BMW EfficientDynamics development strategy.

• Innovative approach in the context of BMW EfficientDynamics: The exceedingly good balance of CO2 emission management and driving pleasure results from a revolutionary vehicle concept developed all in one from the ground up, achieving a new level of efficiency combined with a unique driving experience. The overall result goes far beyond the sum total of the individual features and components in this concept car.

• BMW Vision EfficientDynamics offers a realistic impression of the unique potential of BMW ActiveHybrid technology and the great innovative thrust of BMW EfficientDynamics.

Technology

• Offering a full-hybrid concept, the BMW Vision EfficientDynamics concept car is powered by a three-cylinder turbodiesel and two electric motors. Overall system output is 262 kW/356 hp, maximum torque 800 Newton-metres/590 lb-ft. All-wheel drive featuring an electric motor on both the front and rear axle.

• Anticipated performance: Acceleration from a standstill to 100 km/h in 4.8 seconds, top speed 250 km/h (155 mph) (electronically limited) , fuel consumption in the EU test cycle 3.76 litres/100 km (equal to 75.1 mph imp), CO2 emissions 99 grams/kilometre.

• As a plug-in hybrid, BMW Vision EfficientDynamics is able to cover the entire fuel consumption drive cycle under electric power alone. Taking the sources of energy used for generating the electric power consumed into account (EU electricity mix), this reduces the CO2 emission rating to just 50 grams per kilometre.

• Electric power is generated without the slightest increase in fuel consumption through a particularly efficient concept of Brake Energy Regeneration. Energy is stored in 98 lithium polymer cells. The car is able to cover a distance of approximately 50 km/31 miles in the electric mode alone.

• Aerodynamics developed with know-how from Formula 1. CX drag coefficient optimised to just 0.22. Forward-looking energy management uses the maximum potential available in each case to minimise fuel consumption.

 

 

Design

• Technology-oriented body design as a clear expression of consistent lightweight technology and aerodynamic quality. Design language typical of the brand, setting clear signals in terms of sporting performance and optimum efficiency.

• The 2+2-seater concept combines dynamic performance and supreme efficiency with an enhanced level of all-round function. BMW Vision EfficientDynamics symbolises BMW’s commitment to offer an unprecedented driving experience for up to four occupants.

• BMW Vision EfficientDynamics comes with gullwing doors opening up to the side. Innovative, weight-optimised door kinematics makes entering the car at both front and rear convenient and very easy.

• The interior of this unique 2+2-seater intentionally demonstrates the very latest in modern technology. At the same time the use of natural materials underlines BMW’s strategy of sustainability borne out through this concept car.

• The roof and door inserts made of polycarbonate glass automatically become darker as a function of incoming light.
