BMW Efficient Dynamics

Less emissions. More driving pleasure.
At BMW, we have a plan to reach zero emissions. It's called BMW EfficientDynamics. We will continue to reduce emissions and maximize fuel economy through the use of lightweight materials, aerodynamics, and our efficient internal combustion engines. In 2008, this will include introducing our clean, Advanced Diesel engines to Canada. We will then launch ActiveHybrid vehicles in 2009 as we work towards a cleaner future. To reach our ultimate goal of zero emissions, we will remain focused on liquid hydrogen as the long-term sustainable source of automotive energy. Because at BMW, it's our goal to do for the environment what we did for performance.

Our vehicles already contain a number of energy management innovations that make them amongst the most eco-conscious on the market today. Our engines equipped with Valvetronic® achieve 10-15% gains in fuel efficiency while delivering similar increases in horsepower. Double-VANOS technology optimizes engine breathing, resulting in greater responsiveness with reduced fuel consumption. Lightweight construction technologies such as carbon fiber roofs, aluminum/magnesium engines and lightweight steel further increase fuel efficiency, while optimized aerodynamics reduce drag resulting in decreased CO2 emissions. All of these technologies work in tandem to produce our environmentally responsible, high-performance vehicles of today.

TwinPower Turbocharged 4-Cylinder Engine
6-Cylinder performance with 4-cylinder efficiency BMW’s first turbocharged gas (petrol) engine debuted in the 2007 BMW 335i. Throughout the past few years, BMW has essentially turned its lineup of award-winning naturally-aspirated engines into a lineup dominated by turbocharged units. Not surprisingly, the new engines have already won several awards, including the Engine of the Year Award that the twin-turbo six-cylinder engine captured for consecutive years. The path towards turbocharged engines is a result of BMW’s EfficientDynamics strategies, set to increase performance and driving pleasure, while at the same time, reducing fuel consumptions and emissions. The new TwinPower 2.0-liter inline-4-cylinder engine does exactly that. Fitted to the upcoming BMW X1, the engine has more power than the outgoing 6-cylinder, and takes the car to 100 km/h in just 6.1 seconds (manual transmission) – an improvement of 0.7 seconds over the previous engine. Additionally, fuel consumption has decreased substantially, by nearly 20%. In the European test cycle, the BMW X1 fitted with the new turbo 4-cylinder engine used an average of 7.9 liters/100 km, a reduction of 1.5 liters. (Note: European fuel economy testing differs from the Canadian test). The new turbocharged 4-cylinder powerplant achieves the twofold goal of BMW EfficientDynamics in impressive style: it continuously raises the bar on driving pleasure, while at the same time reducing fuel consumption and emissions.
BMW xDrive All-Wheel Drive
xDrive offers all-wheel-drive peace of mind No matter the road, no matter the weather, xDrive All-Wheel Drive delivers legendary handling with advanced traction and control. Now available on 17 different BMW models, from the BMW 3 Series Sedan, Coupe and Touring, the BMW 5 Series Sedan and Gran Tourismo, and 7 Series Sedan, to our X3, X5 and X6 Sports Activity Vehicles. As well, exciting and new to the xDrive model lineup are the BMW X5 M and the BMW X6 M where X meets M for even higher performance. Unlike other all-wheel-drive systems, we've built ours with rear wheel bias for surefooted grip on slick roads, without sacrificing the feel of rear wheel drive. It smartly sends power to the wheel or wheels with the surest footing - and it does so in milliseconds. That means under normal conditions, drive forces are spread out with a rear-wheel bias. But the moment the system senses excessive wheel slip, it subtly shifts torque to meet the changing conditions, offering maximum available traction and superior handling on all surfaces.
8-Speed Automatic Transmission
Ultra smooth and millisecond shifting Although much of a car's performance and efficiency is dependent on its engine, BMW's new 8-speed Automatic transmission greatly affects the performance and fuel consumption of the new 760Li, 5 Series, X5, and X6. The new 8-speed transmission weighs no more than the outgoing 6-speed, yet offers closer ratios in the lower gears for improved acceleration, and two additional "tall" gears for smooth, efficient, and quiet highway cruising. Simply put, it means BMWs equipped with the new transmission will run at a lower RPM at highway speeds, and return better fuel efficiency. The 8-speed automatic transmission is available on the 2011 BMW 760Li, 5-Series Sedan, 5-Series Gran Tourismo, X6 Sport Activity Coupe, and X5 Sport Activity Vehicle (not available on X5 xDrive35d).
Brake Energy Regeneration
Power from your brake pedal With Brake Energy Regeneration, BMW EfficientDynamics point the way to a more energy-efficient future. On many new BMW models, like the all-new 2011 BMW 5-Series, Brake Energy Regeneration reduces fuel consumption over time. The car's generator starts converting excess kinetic energy and storing it in the battery when the driver's foot is taken off the accelerator. When the driver presses the accelerator, on the other hand, the alternator is decoupled from the drivetrain. The system intelligently manages the times at which the alternator charges the battery for maximum efficiency. Conventionally, a car's alternator runs to continuously charge the vehicle's battery. In the application of the new 5 Series, the alternator only charges the battery when the car is braking or decelerating, and does not draw power from the engine in other situations. The process reduces fuel consumption by 1-2% over time.
BMW ActiveHybrid Technology
A new unique approach to the hybrid automobile segment. Depending on the configuration of the vehicle, BMW ActiveHybrid technology offers the driver three significant options: to drive under electric power alone, to use the power of the combustion engine, or to benefit from the combination of both drive modes. The vehicle can be driven in the all-electric mode completely free of fuel consumption and emissions at speeds up to 60 km/h. The combustion engine cuts in as required, and is automatically switched off when driving in overrun at speeds slower than 65 km/h. To understand the effects of BMW's ActiveHybrid technology, consider the ActiveHybrid X6, one of the two models currently available in BMW's hybrid stable. The car pairs BMW's highly-efficient 4.4L V8 gasoline engine to two electric motors. The result is a significant increase in both power and fuel efficiency. The BMW ActiveHybrid X6 pushes 485 hp and 575 lb-ft of torque (up from 400 hp and 450 lb-ft of torque), making it the world's most powerful hybrid vehicle. Simultaneously, fuel consumption and emissions are reduced by nearly 20%. Indeed, the ActiveHybrid X6 is significantly more powerful than the V8 gasoline model of the X6, while consuming fuel slightly more than the six-cylinder iteration of the vehicle.
BMW Advanced Diesel
Diesel, Reinvented. BMW has mastered diesel technology after decades of research, development, and production. Interestingly, although not very common in the North American market, diesels account for about 2/3 of BMW’s sales in Europe. The North American aversion to diesel-powered automobiles can mainly be traced back to the terrible record of domestic diesel engines of the 1970s. Rushed to market during the 70s fuel crisis, these diesel engines experienced troubles, and gave diesels the reputation of noisy, smelly, dirty, and sluggish engines. Europeans, on the other hand, have been enjoying the benefits of diesel technology for years. Diesels provide maximum performance and optimum efficiency. In addition to increased torque and significantly improved fuel consumption, today's diesels are clean and environmentally friendly. BMW's North American diesel offering is a powerful 3.0-liter inline-six cylinder dual-turbocharged engine boasting 425 lb-ft of torque at just 1,750 rpm. That is where BMW Advanced Diesels shine. With excessive amounts of torque available early in the rev-range, the 335d and X5 xDrive35d feel effortlessly quick and powerful right from the start of every acceleration. The torque that diesel engines produce is unmatchable with a gasoline engine of a similar displacement. The 3.0L diesel in the 335d and X5 xDrive35d have more than twice the horsepower and three times the torque of the first diesel BMW produced close to 30 years. Yes, BMW's Advanced Diesel engine is extremely powerful. What's even more promising with BMW's diesel technology is the renowned fuel efficiency. The powerful 335d consumes 9.0L of fuel in the city, and sips just 5.4L on the highway. That's compared with 11.9L and 7.6L consumed by the 335i. And the sprint to 100 km/h only takes a mere 0.2 seconds longer. And rest assured that your new diesel-powered BMW is clean for the environment. A Particular Filter removes the smallest particles of nitric oxides from the exhaust without impacting performance or efficiency. And a catalyst converts any remaining particles of nitric oxides into nitrogen and water vapor, before releasing them through the tail pipe.
Virtual Displacement
Downsizing Engines. Upsizing Performance. BMW's EfficientDynamics program is all about achieving maximum performance and driving dynamics with minimum fuel consumption and environmental impact. Many technologies are built into every new BMW to make the vehicle more fuel efficient. One of these achievements is what BMW calls virtual displacement. For many years, the most common method of exerting more power and torque from an engine has been adding cylinders and increasing its displacement (size). With “Virtual Displacement”, BMW is doing the exact opposite. Vehicles previously powered by eight-cylinder engines can be replaced by models powered by innovative and efficient, yet powerful six-cylinder units. Reducing engine sizes and adding technologies like direct injection and turbo-charging has allowed BMW to achieve V8 performance from an Inline-6, and the performance of a V12 from a V8. For example, in 2009, BMW launched the all-new 7 Series lineup. Here is a comparison of the 2008 760Li (6.0L V12 engine) and the 2009 750Li (4.4L V8 engine): 2008 BMW 760Li 6.0L V12 engine 438 horsepower 444 lb-ft torque 0-100 km/h in 5.4 seconds 16.8L/100 km City, 10.9L/100 km Highway 2009 BMW 750Li 4.4L V8 Twin-Turbo engine 400 horsepower 450 lb-ft torque 0-100 km/h in 5.5 seconds 14.6L/100 km City, 9.2L/100 km Highway The 2009 BMW 750Li matches the performance of the outgoing 12-cylinder 760Li, while on average using two liters less fuel for every 100km. That's nearly a 15% improvement. Furthermore, consider the brand new 2011 BMW X5 xDrive35i. With a 3.0L turbo-charged inline-six, the Sport Activity Vehicle accelerates from a standstill to 100 km/h in the same 6.8 seconds as the outgoing 4.8L V8 model (2010 BMW X5 xDrive48i), while using over 25% less fuel. BMW's EfficientDynamics technologies that are fit together to create Virtual Displacement are an effective means to reducing fuel consumption and our impact on the environment.
Electric Power Steering
A turn for the better. To give you more bends per liter, an electric motor is used to assist the steering in many recent BMWs. Unlike conventional hydraulic systems, Electric Power Steering is supported by an electric motor which helps to ensure that energy is only used during actual steering maneuvers. If the steering wheel is kept in a constant position when driving straight ahead or cornering, the electric motor is inactive and therefore does not use any energy. Like some other BMW EfficientDynamics technologies, Electric Power Steering will improve fuel consumption by a few percent over time, while continuing to deliver the Ultimate Driving Experience that BMW is known for.
