BMW Efficient Dynamics

The BMW development strategy EfficientDynamics continues to be pursued consistently with new models optimised for reduced fuel consumption and exhaust emissions. For model year 2008, the launch of especially efficient engines also in the high-volume BMW 3 Series will make a major contribution to the overall reduction in exhaust emissions. By autumn 2007 around 40% of all BMW Group (BMW, MINI, Rolls-Royce) cars sold in Europe come with maximum C02 emissions of 140g per kilometre. They confirm the obviousness of the measures that were initiated in the BMW engineering departments 5 years ago.

In the model year 2008, the number of BMW Group vehicles with a maximum CO2 level of 140 g per kilometre increases to 22. Three of them are MINI models and two of them belong to an additional BMW model line. This extension of the range of especially low-emission models is made possible by the newly developed 4-cylinder petrol and diesel engines for the BMW 3 Series and the market launch of the new BMW 123d and the new BMW 520d.

With its average consumption of 5.1 litres of diesel per 100 kilometres as determined by the EU test cycle and a CO2 level of 136 g per kilometre, the BMW 520d sets new standards in its segment.

The new 1.6 litre 4-cylinder with direct injection in lean combustion operation makes the most efficient of the petrol engines, resulting in outstanding levels in terms of fuel consumption and exhaust emissions in the new BMW 116i (5,8 litres, 139 g). The 4-cylinder diesel engine with Twin Turbo in the new BMW 123d (5.2 litres, 138 g) provides an especially fascinating combination of driving fun and economy. There are also new engines available for the BMW X5, the BMW X3 and the new BMW 6 Series which provide a unique relationship between driving dynamics and economy as compared to the competition within their respective vehicle categories.

The innovations developed as part of the BMW EfficientDynamics strategy are available to customers as standard in all new BMW models. With the ongoing introduction of new efficiency-increasing measures in all series, BMW is ensuring that its technologies to reduce fuel consumption and exhaust emissions will become as widespread as possible.

Increased dynamic performance, reduced CO2 - the result of a long-term strategy.

The variety of highly economic models across the various model series is the result of the long-term and consistently pursued development strategy BMW EfficientDynamics. Within the voluntary VDA commitment BMW reduced fleet C02 emissions already by 30 per cent between 1990 and 2005. Development work continues to focus on the aim to ensure that each new model surpasses its predecessor both in driving dynamics and in economy. In conjunction with BMW's outstanding expertise in the field of engine development, this has led to the production of vehicles which set new benchmarks in both areas within their various competitive environments. The optimisation of fuel consumption and exhaust emission levels is not only limited to special models but is a standard component of the product substance in all new vehicles.

Increased output, lower fuel consumption - this principle applies to all model series for the engine types newly introduced in the model year 2008. It is implemented with new petrol and diesel engines as well as with a wide range of engine measures which increase efficiency.

High Precision Injection for 6 and 4-cylinder engines:

In addition to the in-line 6-cylinder engines, BMW's 4-cylinder power units now also have petrol direction injection in its second generation. The technology is known as High Precision Injection and enables so-called lean combustion operation across a broad engine speed range, resulting in significant reductions in fuel consumption in everyday traffic. The highly precise and efficient fuel injection is carried out by piezo injectors which are positioned between the valves in the cylinder head and thus in immediate proximity to the spark plug.

In the model year 2008, 4-cylinder engines with High Precision Injection in lean combustion operation are used in the new BMW 520i, in all versions of the BMW 3 Series and the BMW 1 Series. In addition to the two engines already introduced with a capacity of 2.0 litres each, a new 1.6 litre petrol direct injection engine in the new BMW 116i now also sees its premiere. As compared to the predecessor engine in each case, the three new 4-cylinders have an output which is has been increased by between 5 and 15 kW. Nonetheless, fuel consumption in the models fitted with these engines drops by up to 23 per cent.

4-cylinder diesel with the latest common rail technology and now also with Variable Twin Turbo:

In the model year 2008 , the new generation of 4-cylinder diesel engines is also completed. The 2.0 litre lightweight construction aluminium units are now available in up to three output levels for the BMW 5 Series, the BMW 3 Series and the BMW 1 Series as well as the BMW X3. They are fitted with the latest version of common rail injection, in which piezo injectors convey the fuel into the combustion chambers - at a pressure of up to 2,000 bar for the first time. The most powerful version of the new 4-cylinder diesel engine is presented in the BMW 1 Series. It has a supercharging technology referred to as Variable Twin Turbo which was already used in the BMW in-line 6-cylinder diesel engines. This system consists of two turbochargers of different sizes. Due to is low moment of inertia, the smaller of the two turbochargers develops its performance-enhancing effect even at low engine speeds and without any noticeable delay. As the engine speed increases, the larger turbocharger comes into use. This combination ensures an impressive level of power delivery which is unsurpassed in its spontaneity.

The new 4-cylinder in the BMW 123d delivers 150 kW/204 bhp and is thus the world's first all-aluminium diesel engine with a power output per litre of over 100 bhp. Due to its extremely precise fuel dosage and the high level of efficiency of its combustion process, it also achieves top figures in terms of economy - just like the other two new diesel engines. The BMW 123d makes do with 5.2 litres of diesel per 100 kilometres in the EU test cycle. Its CO2 level is 138 g per kilometre.

Even greater efficiency thanks to brake energy regeneration, Auto Start Stop Function and needs-oriented control of ancillary units:

In addition to the design of engines which are optimised for reduced fuel consumption and exhaust emissions, the development strategy BMW EfficientDynamics also includes a wide range of other measures which contribute to the increase of driving pleasure and economy in each new model. Among other things, the focus here is on weight optimisation, reduction of road resistance and the improvement of aerodynamics. Measurable progress towards favourable fuel consumption levels can also be made by means of intelligent energy management. In the model year 2008 there is a further increased number of vehicles in which these measures have been applied. The combination of measures to increase efficiency in the vehicle and within the engine environment is specifically adapted to each model and engine type. The measures are thus not limited to special models but are an integral part of every vehicle's standard fittings.

In future, all models of the BMW 6 Series, BMW 5 Series, BMW 3 and BMW 1 Series as well as the BMW X5 will be fitted with brake energy regeneration. It is the result of intelligent energy flow management which leads to a more efficient use of the energy contained in the fuel and increased dynamic performance on acceleration manoeuvres. By means of brake energy regeneration, the generation of electrical current for the vehicle power supply is focused on the vehicle's trailing throttle and braking phases. During the pulling phases, however, the generator is decoupled, providing more drive energy for conversion into driving dynamics.

Auto Start Stop Function was presented for the first time in spring 2007 in the new BMW 1 Series and in the BMW 320i Coupé/Convertible. In the model year 2008 enables a reduction of idling phases on interim stops at junctions or in traffic jams in all other 4-cylinder versions of the BMW 3 Series. As soon as the driver puts the gear lever into the neutral position and removes his foot from the clutch, the engine is automatically switched off. As soon as further travel is possible, it is sufficient to activate the clutch and the engine starts without delay.

Other features for refining energy management in the vehicle include the needs-oriented control of ancillary units, the use of electrical steering and a Varioserv steering pump and the decoupling of the air conditioning compressor. For example, needs-oriented control of the coolant pump uses significantly less energy than conventional systems which run permanently at full capacity. The servomotor of the electric steering is only activated when steering boost is required or desired by the driver. With the Varioserv steering pump, the cam ring is adjusted in relation to pressure and volumetric flow so as to avoid the loss of drive train power as the engine speed increases. The power dissipation of conventional air conditioning compressors can also be reduced by means of intelligent regulation. In the new BMW models, the compressor is separated from the belt drive by means of a magnetic coupling as soon as the air conditioning system is out of operation.

These measures reduce the amount of electrical energy required, and as a result the generator has to convert significantly less primary energy into electrical current. A special low viscosity transmission oil contributes to the reduction of frictional loss. What is more, optimised heat management for the rear-axle drive ensures that frictional resistance is reduced more quickly after starting. The reduction of aerodynamic resistance also supports the decrease of fuel consumption. With cooling air flaps which open or close depending on the driving situation and which are actively controlled in some models, the aerodynamic properties of a vehicle can be further optimised.

The driver also receives support in the choice of the most economical driving style from the gear shift indicator. This system uses data provided by the engine control unit to calculate in each situation the most favourable point at which to shift down or up from the point of view of economical fuel consumption. The signal to change gear appears in the instrument panel. Here an arrow symbol and a figure show which gear would be most suitable for economical motoring.

BMW EfficientDynamics is a fixed element of every new BMW. The selection of measures is tailored specifically to each model, however. The following list shows which features are available in which models.

Brake Energy Regeneration: as standard in all models of the BMW 6 Series, BMW 5 Series, BMW 3 Series and BMW 1 Series as well as the BMW X5.

Auto Start Stop Function: as standard in all models with 4-cylinder engine (petrol and diesel) and manual transmission in the BMW 3 Series and BMW 1 Series.

Gear shift indicator: as standard in all models with manual transmission of the BMW 6 Series, BMW 5 Series, BMW 3 Series and BMW 1 Series.

Electrical steering: as standard in all models of the BMW 3 Series and BMW 1 Series except for the BMW 335i and the all wheel drive models.

Varioserv steering pump: as standard in the BMW 630i, 635d and all models of the BMW 5 Series and BMW X3.

Air conditioning decompressing with decoupling function: as standard in all models of the BMW 6 Series, BMW 5 Series, BMW X5, BMW 3 Series, BMW 1 Series except for the BMW 335i, 330d, 325d.

Electrical water pump: as standard in all models with 6 and 4-cylinder petrol engine of the BMW 6 Series, BMW 5 Series, BMW 3 Series and BMW 1 Series, in the BMW X3 (without X3 2.0i) and BMW X5.

Active aerodynamics: as standard in the BMW 635d, in all models of the BMW 5 Series, BMW 3 Series. BMW 1 Series and BMW X3 (without X3 2.0i, X3 3.0sd), BMW X5. Not available in 335i, 335d and all-wheel drive models of the 3 and 5 Series.

Tyres with reduced rolling resistance: Standard tyres in the BMW 525i, BMW 525d, BMW 520i, BMW 520d and in all models of the BMW 3 Series and BMW 1 Series, as well as BMW X3 (except X3 3.0sd) and BMW X5.

The new BMW 6 Series: with a diesel engine for the first time:

The new BMW 6 Series is stylishly assured in its appearance and progressive in its technology in the model year 2008. With specific modifications to its characteristic design, an interior which has been refined in selected details and enhanced with new colour accentuations, innovations in the engine area and driver assistance and safety systems, the new BMW 6 Series Coupé and the new BMW 6 Series Convertible acquire an increased fascination. The most important new feature under the engine compartment lid: for the first time in a vehicle of this segment, a diesel engine delivers the pulling power and economy. As the world's most powerful engine of its kind, the 3.0 litre in-line 6-cylinder diesel with Variable Twin Turbo gives the BMW 6 Series its efficient dynamics in an especially impressive manner. 210 kW/286 bhp and a maximum torque of 580 Nm makes for a sporty driving performance. The BMW 635d Coupé requires no more than 6.3 seconds for acceleration from zero to 100 km/h, the Convertible does the spurt in 6.6 seconds. The fuel consumption determined according to the EU test cycle is 6.9 litres for the Coupé and 7.2 litres for the Convertible. The resulting increase in range to 1,015 kilometres in the Coupé and 970 kilometres in the Convertible is in keeping with the long-distance character of the model - a traditional feature of Gran Turismo vehicles.

Increased efficiency is also a characteristic feature of the two other engine types in the BMW 6 Series. The leader here is the 270 kW/367 bhp 8-cylinder engine in the BMW 650i Coupé and BMW 650i Convertible, also fitted with additional measures to reduce fuel consumption. With the introduction of a new power unit for the BMW 630i, petrol direct injection now enters the BMW 6 Series, too. The new in-line 6-cylinder with High Precision Injection delivers 200 kW/272 bhp. It is thus 10 kW more powerful than its predecessor engine. The new BMW 630i Coupé now manages the spurt from zero to 100 km/h in 6.2 seconds, the Convertible takes 6.7 seconds. The fuel consumption of the BMW 630i as determined by the EU test cycle is 7.9 litres per 100 kilometres for the Coupé and 8.3 litres for the Convertible - as much as 15 per cent below the levels of the predecessor models, which were themselves highly efficient.

The BMW 5 Series: greater variety, increased economy:

In the new BMW 5 Series, there are six petrol and four diesel engines to choose from in the model year 2008. More than ever before, the Sedan and Touring realise their aspiration to set benchmarks both in driving performance and economy. The two new entry level versions of the BMW 5 Series - the BMW 520d and the BMW 520i - show just what the development strategy of efficient dynamics is capable of achieving in this vehicle category. The new BMW 520d is powered by a newly developed 4-cylinder diesel engine whose output has been increased over the predecessor engine by 10 kW to 130 kW/177 bhp. Both in the Sedan and in the Touring model this results in a perceptibly higher level of driving dynamics. For example, the Sedan now accelerates from zero to 100 km/h in 8.3 seconds, the Touring in 8.5 seconds. At the same time, fuel consumption in the two models is reduced by around 14 per cent. Like the Sedan, the new BMW 520d Touring also achieves outstanding levels within its segment, with an average fuel consumption 5.3 litres per 100 kilometres in the EU test cycle and a CO2 output of 140 g per kilometre.

The BMW 520i performs a similar role model function in the petrol engine domain. Its 125 kW/170 bhp 4-cylinder power unit with High Precision Injection provides driving fun which is reflected in acceleration rates of 8.7 (Sedan) and 9.0 seconds (Touring) for the spurt to 100 km/h. The efficiency-enhancing qualities of the new engine are equally clearly demonstrated: for the new BMW 520i, the EU test cycle gives an average fuel consumption of 6.7 litres per 100 kilometres (Touring: 6.9 litres) and a CO2 level of 162 g per kilometre (Touring: 166 g). Both in the BMW 520d and the BMW 520i, BMW realises a level of efficiency which is still exceptional even in the smaller vehicle categories.

The BMW 3 Series: more dynamic, more efficient - the lead increases:

The BMW 3 Series consolidates its status as the sportiest and at the same time most progressive car in the segment in the model year 2008 with the introduction of new engine variations which are both powerful and economical. Efficient dynamics once again characterises the extension of the model range in this model series. New 6-cylinder and 4-cylinder petrol engines with the direct injection system High Precision Injection in lean combustion operation and the new 4-cylinder diesel engines with common rail injection of the third generation are now available for the Sedan, the Touring model, the Coupé and the Convertible of the BMW 3 Series.

Six petrol engines, five diesel power units - never before has the engine range of the BMW 3 Series been so large. Along with this variety, the lead of the BMW 3 Series over competitors also continues to increase when it comes to the ideal relation between driving dynamics and economy. For the first time, all petrol engines - both the 6 and the 4-cylinder units - are fitted with the direct injection system known as High Precision Injection. The spectrum now ranges from the BMW 118i to the 3.0 litre in-line 6-cylinder in the BMW 335i, whose combination of High Precision Injection and Twin Turbo takes it up to an output level of 225 kW/306 bhp.

Within the BMW 3 Series alone there are now five models to choose from whose CO2 level in the EU test cycle is no more than 140 g per kilometre. The front runner in terms of efficiency and emissions among the diesel models is the new BMW 318d. Its 105 kW/143 bhp 4-cylinder diesel engine with common rail injection of the third generation allows both the Sedan (4.7 litres/100 kilometre, 123 g CO2/km) and the Touring model (4.8 litres/100 kilometre, 125 g CO2/km) to achieve levels of fuel consumption and exhaust emission levels which are unbeatably low.

The BMW 1 Series: premiere for new engines:

In the model year 2008, the BMW 1 Series is extended to include a fascinating body variation. There are three new BMW 1 Series engines which celebrate their premiere in the model year 2008. For the first time in the model year 2008, the new 4-cylinder diesel engine with Variable Twin Turbo is available both for the 5 and 3-door models. The 150 kW/204 bhp power unit gives the BMW 123d a unique status in a number of disciplines. The new model has a particular fascination due to its degree of pulling power, which is unique within its segment, and it also has outstanding fuel consumption levels. The 5-door and 3-door models make do with 5.2 litres of diesel for 100 kilometres in the EU test cycle. The CO2 level of the BMW 123d is 138 g per kilometre.

With these figures, the new BMW 123d symbolises the spirit and also the potential of the development strategy BMW EfficientDynamics in a particularly striking manner. Its engine is the world's first all-aluminium diesel power unit to deliver an output of over 100 bhp. At the same time, the BMW 123d is the first large-series vehicle over 200 bhp whose CO2 output is below the 140 g level.

The BMW X5: outstanding qualities - in the area of efficiency too:

With superior driving dynamics, a powerfully expressive design, a luxurious ambience and great interior versatility, the new BMW X5 continues to consolidate its leading position within its segment. With an extended selection of engines, the successful Sports Activity Vehicle (SAV) raises the benchmark once more in terms of efficiency in the model year 2008. Supremacy in particularly economical form is embodied most clearly by the new BMW X5 3.0sd, which is powered by a 3.0 litre in-line 6-cylinder diesel engine with Variable Twin Turbo. 210 kW/286 bhp and a maximum torque of 580 Nm enable an acceleration of zero to 100 km/h in just 7.0 seconds. 8.2 litres per 100 kilometres is the average fuel consumption according to the EU cycle. This gives the new BMW X5 3.0sd a maximum range of 1,035 kilometres - a long-distance capacity which is outstanding within the segment.

214g/km tax-busting BMW X5 3.0d revealed:

A new BMW X5 3.0d goes on sale in October with a revised powerplant for lower emissions and improved economy. The new X5 is now the only conventionally-powered vehicle in its segment with a CO2 emissions figure that falls below the highest 225g/km banding for Vehicle Excise Duty.

Engineers have utilised BMW’s EfficientDynamics know-how and applied it to the BMW X5 3.0d to achieve this impressive result. The new model now comes with Brake Energy Regeneration and various needs only control of ancillary devices. An air-conditioning compressor that decouples from the drivetrain when not in use and air flaps that can close off air flow to the engine to improve aerodynamics when the engine is not at full load are two such examples. All of these features enable the model to produce a CO2 emission figure of 214g/km – a drop of 17g/km compared to the previous model.

The changes on the X5 3.0d have resulted in the vehicle now qualifying for Band F instead of Band G Vehicle Excise Duty, saving owners £95 a year. Fuel consumption on the combined cycle also improves from 32.5mpg to 34.9mpg, as does acceleration from zero to 62mph – down to 8.1 seconds from 8.3 seconds.

News of the revised 3.0-litre diesel comes at the same as fuel saving technology has been applied to the range-topping 4.8-litre petrol and 3.0-litre petrol-engined variants. The BMW X5 3.0si now records an improved combined consumption figure of 27.7mpg compared to 25.9mpg. Emissions have been cut from 260g/km to 244g/km. Meanwhile, the BMW X5 4.8i sees its consumption figure improve from 22.6mpg to 23.5mpg and the CO2 emissions figure drop from 299g/km to 286g/km

Other model variations of the BMW X5 also have extensive measures to optimise fuel consumption and exhaust emissions, including brake energy regeneration and needs-oriented control of the ancillary units. In the top model of the series, the BMW X5 4.8i powered by a 261 kW/355 bhp 8-cylinder engine, the average fuel consumption is reduced by 4 per cent to 12.0 litres per 100 kilometres according to the EU test cycle. The BMW X5 3.0si manages 10.2 litres - a reduction of 6 per cent - and the average fuel consumption of the BMW X5 3.0d is now 8.1 litres per 100 kilometres, a reduction of 7 per cent as compared to the level achieved in model year 2007. The BMW X3 2.0d is now also available with the new, quick-shifting six-speed automatic transmission.

The BMW X3: number one in the segment in terms of dynamic performance and economy:

Versatile, agile and high-quality like no other vehicle in its segment: the BMW X3 is consistently on course for success once again in the model year 2008. In addition, the Sports Activity Vehicle also sets new standards in the field of economy. Six state-of-the-art petrol and diesel engines are available.

The leader of the segment in terms of efficiency will be the new BMW X3 2.0d. Its all-aluminium 4-cylinder diesel engine delivers 130 kW/177 bhp and mobilises a maximum torque of 350 Nm. With an average fuel consumption based on the EU test cycle of 6.5 litres per 100 kilometres and a CO2 level of 172 g per kilometre, the new BMW X3 2.0d achieves the best levels in its vehicle category in the model year 2008.
*

The most popular model in the BMW X3 range is to receive a boost following the introduction of a revised engine with EfficientDynamics technology. The new BMW X3 2.0d comes with a 1,995cc engine offering 177hp, up 27hp compared to the previous model, and 350Nm of torque, up 20Nm.

Enhanced engine output results in better performance figures for the model that accounts for 70 per cent of X3 sales in the UK. The X3 2.0d now records an 11 per cent improvement in fuel consumption attaining 43.5mpg on the combined cycle. The vehicle’s CO2 emissions also fall 10 per cent from 191g/km to 172g/km seeing it drop into Band E for Vehicle Excise Duty.

As is the case with all BMWs touched by EfficientDynamics technology, improvements in economy and emissions have not been at the expense of driving pleasure. A zero to 62mph time of 8.9 seconds compares to 10.2 seconds previously, while top speed has increased from 123mph to 128mph.

To complete the picture of X3 2.0d revisions, the model is now offered with the option of BMW’s Steptronic automatic transmission. The six-speed gearbox is available on both SE and M Sport variants of the X3 2.0d at a cost of £1,470. The introduction of an automatic gearbox to the model satisfies customer demand but has a limited impact on performance figures compared to a manual gearbox. An auto-equipped BMW X3 2.0d still maintains 42.2mpg on the combined cycle and posts a 178g/km emissions figure.

Other models in the BMW X3 range also receive EfficientDynamics technology and a consequential improvement in overall performance. The next two popular models in the range, the X3 3.0d and 3.0sd, both see fuel consumption improve by seven per cent and 11 per cent to 38.2mpg and 36.2mpg respectively on the combined cycle. CO2 emissions on both those models also fall by seven and 10 per cent. This results in the BMW X3 3.0sd, joining the 2.5si in dropping a tier in Vehicle Excise Duty from Band G to Band F making for a £95 annual saving.

Model / Power Hp / Increase in HP / New Combined Mpg / Improvement of % / New emissions g/km / g/km decrease %

BMW X3 2.0d 177 +27 43.5 +11 172 -10
BMW X3 2.5si 218 0 30.4 +7 224 -6
BMW X3 3.0si 272 0 29.1 +6 233 -6
BMW X3 3.0d 218 0 38.2 +7 196 -7
BMW X3 3.0sd 286 0 36.2 +11 208 -10


BMW EfficientDynamics enables leading position in all segments:

The engines and model variations launched in the model year 2008 secure a leading position in terms of efficiency in all the relevant segments for BMW. This is the result of the development strategy BMW EfficientDynamics, which has been pursued by the BMW Group for many years in engine development and today already provides an impressive response to the demands of the future in terms of fuel consumption and exhaust emission levels. The result: dynamic vehicles with significantly reduced fuel consumption and CO2 levels as compared to the predecessor models in each case.

The leading position occupied by the new BMW models within their competitive field does not arise from a short-term shift of priorities but is based on a fundamental and long-term orientation of development work. In the new models, technological developments are used which were decided as part of the BMW EfficientDynamics strategy some five years ago and which have now reached a state of readiness for serial production. As a result, not only the highly efficient petrol and diesel engines but also extensive measures for the reduction of fuel consumption and exhaust emissions are now available to a large number of new models. Thus the highly effective package to increase efficiency is not limited to individual special models or niches but forms an integral part of the standard fittings of all new BMW models.

Great information, thanks. These are the types of refinements that are going to be standard across many manufacturers in the coming years IMO.

My 08 535 order is September production, as that is when the first manual transmissions are available. It appears that the efficient dynamics improvements may hit it as well; Brake Energy Regeneration, Gear shift indicator, Varioserv steering pump, Air conditioning decompressing with decoupling function, Electrical water pump, Active aerodynamics, could all be included, or they may be delayed production. Any info yet on actual production dates for these features on the '08 models?

2008 facelift 5-series already has most of these features of Efficient Dynamics and is available now. 3-series is getting in fall this year. 7-series gets it with next gen with bi-turbo V8 and 8 speed transmission.

Thanks Lemans

Now just to wait and see if it comes with BER and active aerodynamics, as the rest of the items listed are shown in your post.

It does come with BER. From my post on press release:

Power units: opening up a new dimension of Efficient Dynamics.
Depending on the specific engine involved, the various models in the new BMW 5 Series come with a range of technologies and features serving to minimize fuel consumption and emissions. For example, one such technology is Brake Energy Regeneration, which concentrates the generation of electricity for the on-board network on the car’s overrun and brake phases.

Operating on-demand, the electrical coolant pump in the new BMW 5 Series 6-cylinder engines consumes significantly less power than a conventional pump and helps the engine reach its normal operating temperature earlier. The Varioserv steering assistance pump, varying the curve ring as a function of pressure and volume flow, avoids the usual increase in drive losses as a function of higher engine speeds. And when the driver and passengers do not require the air conditioning, the a/c compressor is disconnected to reduce drag forces to a minimum.

Thanks, I saw that, it just doesn't say which engines. Also, the CA and US web sites don't list any of these features. The tech literature hasn't reached my dealer yet, they don't have details on which features have different SOP dates. The press release you posted said that all the Efficient Dynamic features will eventually apply to all models. Given the noise being made about BER arriving in the 3 series in the fall, it seemed to me that if it was already on the E60 in North America it would have received some press. I hope I am wrong, I would like to have it. Thanks again.
