v8s, v10s, and v12s are going to be a thing of the past...let's take a look at where BMW is headed at =)...

A milestone for the future.
BMW EfficientDynamics a million times over.

Thanks to the consequent reduction of fuel consumption and emission levels, BMW EfficientDynamics has been able to reach yet another milestone: more than 1,000,000 vehicles worldwide are already equipped with fuel-saving technologies as standard which is further proof that environmentally friendly mobility and driving pleasure are anything but mutually exclusive. Our incentive - an even more efficient future.


Only at BMW is gold green.
Awards for BMW EfficientDynamics.

The numerous international awards won by BMW EfficientDynamics underline its success and help us to innovate further. The "Grüne Lenkrad" for environmentally friendly technologies, the "World Green Car of the Year" award for the BMW 118d, the "Auto 1 von Europa" from the magazine "Auto-Bild", the "Paul-Pietsch-Preis" from the magazine "auto, motor und sport" for especially innovative developments in the car industry, the "Goldene Öltropfen", the "Innovationspreis" from "AutoScout24", first place in "Top Auto", the "Autorevue Award" for innovation, the "Große Österreichische Automobilpreis" and the "Green Heroes" award for six of our models from the British magazine "What Car?" are just some of the titles that acknowledge our measures to reduce emissions and increase driving pleasure.

Efficient Technologies

Four-cylinder petrol engine.
How many kilometres are there in a litre? 17.2, if you're driving a BMW 116i. That's 5.8 litres per 100 km in accordance with the EU norm. Thanks to continual engine optimisation as part of the BMW EfficientDynamics concept, BMW drivers are now leading the way when it comes to economy. In the blink of an eye, High Precision Injection ensures that no less than 200 injections are supplied - just one of the numerous BMW EfficientDynamics innovations that helps significantly reduce fuel consumption and emission levels.


Four-cylinder diesel engine.
The four-cylinder diesel engines are a perfect example of how BMW EfficientDynamics can help continually improve engine performance. The engine block is made of aluminium and offers optimised combustion chamber geometry while the third-generation common rail fuel injection system introduces the diesel into the combustion chamber at remarkably high pressure - up to 1,600 bar - and with outstanding precision, using state-of-the-art piezo injection technology. The sum of these technologies is what makes the notable difference: significantly reduced CO2 emissions of 119 g/km (for the BMW 118d with manual transmission) to 145 g/km (for the BMW 120d with automatic transmission) yet higher performance levels. Both engines are fitted with a diesel particle filter as standard and comply with EU4 emissions regulations.


The six-cylinder petrol engine with Twin Turbo.
Athleticism and efficiency go hand in hand - as our six-cylinder petrol engine proves. Thanks to High Precision Injection, it gets the most out of every drop of fuel. HPI sends a cloud of precisely blended fuel/air mixture to the spark plug, where it is surrounded by colder air. Combined with the benefits of twin turbo technology, it makes for greater refinement, better performance and lower fuel consumption. By using two small turbochargers instead of a single large one, the twin turbo system ensures boost is available right across the rev range.


The six-cylinder diesel engine with Variable Twin Turbo.
The perfect synthesis of power, fuel efficiency and smoothness: the straight six-cylinder diesel engine with Variable Twin Turbo delivers lag-free acceleration and pulls strongly all the way up to 5,000 rpm. Experience it in the BMW 335d Coupé, for instance, and discover just how athletically and efficiently it performs on the road. A true star among diesels.

The four-cylinder diesel engine with Variable Twin Turbo.
Never underestimate the power of diesel. The BMW 123d is the world's first four-cylinder diesel engine with Variable Twin Turbo. In the engine block, now made solely of aluminium, two different-sized turbochargers are deployed sequentially to dispense extra power right across the rev range. Together with third-generation common rail injection, they push output up to a remarkable 150 kW/204 hp. And keep fuel consumption levels down to just 5.2 litres per 100 km.


If the engine's not running, it's not using any fuel.
The Auto Start Stop function automatically switches off the engine when the car is at a standstill and in neutral, then restarts it as soon as the driver presses the clutch pedal again. Fitted for example to all BMW 1 and 3 Series models with a four-cylinder engine and manual transmission, the Auto Start Stop function helps reduce both fuel consumption and emissions.


Power from your brake pedal.
With Brake Energy Regeneration, BMW EfficientDynamics points the way to a more energy-efficient future. As soon as you brake or take your foot off the accelerator, the kinetic energy is captured and fed to the battery. This reduces the amount of power the battery takes from the engine and hence lowers fuel consumption. When the driver presses the accelerator, on the other hand, the alternator is decoupled from the drivetrain. With fewer components drawing power from the drivetrain, more of the engine's output can go into accelerating the car.


A turn for the better.
Every movement requires energy, this is why Electric Power Steering only acts when it is needed. To give you more bends per litre, an electric motor is used to assist the steering. However, 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 manoeuvres. 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.


Open to increased efficiency.
A constant airflow through the radiator increases air resistance and affects aerodynamics. Electrically controlled vents in front of the radiator open and close the cooling air inlets so that the vents are only opened if cooling air is required. When the vents are closed, air resistance is reduced, as is fuel consumption.


It pays to listen to recommendations.
Changing gear at the right time can result in significant fuel savings. In the 1 Series, 3 Series and 5 Series models with a six-speed manual transmission for example, the gear shift indicator conveniently displays which gear you should select to increase fuel efficiency in your direct line of vision. Depending on your driving style, the system gives recommendations on how to go up and down the gears more effectively.


Attention to detail.
Normal tyres are constantly flexed during use, which costs energy and therefore fuel. Tyres with reduced rolling resistance employ special materials in the tread and side sections which reduce flexing and consequently fuel consumption - on every straight and in every bend.

More hybrid, more BMW - less CO2.
BMW ActiveHybrid.

http://www.bmw.com/com/en/insights/technology/efficient_dynamics/phase_2/activehybrid/_shared/img/x6_concept_vehicle.jpg

Thanks to BMW EfficientDynamics technologies, our internal combustion engines are more economical than ever before. That's no reason for us to rest on laurels though. In fact, we've already moved on to the next phase of the BMW EfficientDynamics strategy: BMW ActiveHybrid which continues to reduce fuel consumption and emissions levels while at the same time ensuring BMW-style driving pleasure. BMW ActiveHybrid represents the intelligent management of energy flows within the vehicle. The strengths of electric motors, such as the ability to deliver maximum torque from zero rpm, make them the ideal partner for the sporty and efficient BMW petrol engines.

BMW presented a hybrid BMW 5 Series as early as 1985. Since then, electronic control systems and batteries have become far more efficient, and the time is now ripe for a hybrid system that offers genuine driving pleasure. That system is BMW ActiveHybrid. Two models will be ready for series production as early as 2009.


Hybrid: the best of both worlds.
The concept behind BMW ActiveHybrid.

BMW ActiveHybrid represents all future BMW hybrid technologies and plays a major role in BMW EfficientDynamics. The aim of BMW ActiveHybrid is to produce up to twenty percent less fuel consumption and emission levels as well as provide the highest level dynamics compared with any similar vehicle.
For BMW, the term hybrid represents the intelligent management of energy flows within the vehicle.
Based on a modular hybrid drive system, optimally chosen hybrid components are integrated tailored to the vehicle type. The BMW Concept 7 Series ActiveHybrid comes with an intelligent symbiosis of the V8 cylinder petrol engine and electric drive as a mild hybrid concept. This allows it be applied to different types of BMW vehicles without diluting their different characters.


Fast torque.
The benefits of BMW ActiveHybrid.

In the automobile sector, hybrid drive stands for the combination of a combustion and electric engine. Together, they provide something that engineers and drivers have long dreamed of: a flat torque curve right from the bottom end of the rev range. In fact, it delivers peak torque from a standstill. Add in the output of an internal combustion engine and you've got a highly impressive set of power and torque curves. The result is that you need less fuel to achieve the same level of performance because, in tandem, the two power units can always operate at maximum efficiency.
In addition, the electric motors act as generators. When the driver comes off the throttle or brakes, the motors convert the kinetic energy into electricity, which then charges the batteries and can be used when next accelerating.


Our strategy for the future.
The BMW Concept X6 ActiveHybrid.

At the 2007 Frankfurt Motor Show, BMW unveiled the BMW Concept X6 ActiveHybrid - a concept vehicle that showcases innovative BMW ActiveHybrid technology in the world's first Sports Activity Coupé. On the road, the BMW X6 Concept ActiveHybrid gives its competitors plenty to think about. The two-mode active transmission increases efficiency by around twenty percent and enables complete electric power driving. The underfloor protection panels front and rear are made of brushed aluminium, the rear underfloor panel moving out when required and covering the tailpipes of the BMW Concept X6 ActiveHybrid while driving on electric power only. Furthermore, the powerful rear, striking front view and clearly shaped contours emphasise the vehicle's modern elegance and athleticism which provides as much enjoyment as it does efficiency.


The right solution in every situation.
The two-mode active transmission of the
BMW Concept X6 ActiveHybrid.

A key component of the BMW Concept X6 ActiveHybrid is its two-mode active transmission developed at the Global Hybrid Cooperation in Troy (USA). This innovative, two-mode technology enables the interplay between the electric motors and the engine to be varied according to the situation. It features two different transmission modes: one that ensures maximum torque when pulling away and in low-speed driving. And another that is optimised for higher speeds and bursts of acceleration - when overtaking for instance. Two-mode active transmission allows the BMW Concept X6 ActiveHybrid to get maximum performance and efficiency from its powertrain at all speeds.


Intelligent. Dynamic. Efficient.
The hybrid components of the
BMW Concept X6 ActiveHybrid.

The innovative, full hybrid, two-mode active transmission (1) is the main hybrid component of the BMW Concept X6 ActiveHybrid. The two-mode active transmission comprises power electronics (2) with an integrated inverter module and a high-performance battery (3). This combines the driving dynamics and efficiency of the combustion engine (4) and the electric drive system in an innovative, intelligent manner.


Maximum efficiency in the luxury class.
The BMW Concept 7 Series ActiveHybrid.

BMW pursues a clear strategy: to implement hybrid technology to gain maximum efficiency. The new BMW 7 Series Sedan is already the most efficient vehicle in its class. The BMW Concept 7 Series ActiveHybrid reduces fuel consumption and emissions by 15 percent versus the same car running on a combustion engine only. Yet a BMW with an electric motor is still a BMW so that the BMW Concept 7 Series ActiveHybrid still offers superior safety, comfort and design. The vehicle's 20-inch light-alloy rims and Bluewater metallic paint finish serve as a particular sign of distinction for BMW's maximum efficiency concept cars.


Awaited with suspense.
The energy management of the
BMW Concept 7 Series ActiveHybrid.

At the core of every hybrid vehicle is the battery. It has to deal with full load peaks, irregular loading cycles and mechanical wear and tear without losing any of its capacity as well as offering high energy density. New, lithium-ion batteries are integrated in the BMW Concept 7 Series ActiveHybrid, which far exceed the performance of conventional battery units. The batteries are connected to the electric motor and other components via the 120V, on-board network. This enables the ongoing use of the air conditioning system even when the Auto Start Stop function has switched off the petrol engine.

BMW CleanEnergy

Technology of the future - available today.

http://www.bmw.com/com/en/insights/technology/efficient_dynamics/phase_2/clean_energy/_shared/img/bmw_hydrogen_7.jpg

What is the future of mobility? To start with, we'll be able to generate energy from hydrogen and driving will be emission-free. And with the BMW Hydrogen 7, the future starts now. This is because it's the first production-ready vehicle to be powered by hydrogen. The combustion engine delivers high performance but almost no emissions to make it a true pioneer of future mobility.


The future is closer than you think.

The BMW Hydrogen 7 is the world's first production-ready hydrogen vehicle. It's already proving itself in the real world too: we're putting 100 of them to the test as loan cars for leading figures from the worlds of culture, politics, business and the media, including Oscar-winning film director Florian Henckel von Donnersmarck and Erich Sixt, chairman of rental car company Sixt AG.
Real-world experience shows that switching to hydrogen can go hand in hand with the comfort, dynamics and safety you'd expect from a BMW.

Very cool. I've heard some bad things about the auto start/stop. After the engine turns off at a stop a lot of times it doesn't re engage and you have to manually start it up.
