BMW held the world debut of the 6th generation BMW 5 Series today in Munich. In the course of five model generations, overall sales of the BMW 5 Series have reached more than 5.5 million units.
The new BMW 5 Series Sedan is making its debut with one eight-cylinder and three six-cylinder gasoline engines as well as two six-cylinder diesels. The range is rounded off by a four-cylinder turbodiesel (the 520d) with an aluminium crankcase and common-rail direct injection.

4-cylinder diesel 520d. Maximum power of the new 2.0-liter, four-cylinder diesel is up 5 kW from its predecessor to 135 kW/184 hp at an engine speed of 4,000 rpm. Maximum torque is up by 30 to 380 Newton-metres (280 lb-ft) all the way from 1,900 to 2,750 rpm. The engine combines a composite aluminium crankcase, the latest generation of common-rail direct fuel injection and a turbocharger with variable turbine geometry.
The increase in power and efficiency over the former model ensured in this way results from consistent optimization of the combustion chambers, the charge system and the cylinder head, as well as the new arrangement of the ancillary units helping to reduce frictional losses to an even lower level than before.
Thermodynamically optimized, the charge system in the four-cylinder diesel engine ensures an optimum flow of power at all speeds and under all loads. An electric adjuster sets the turbine blades in the turbocharger to the current load status of the engine within fractions of a second, the engine thus following the gas pedal immediately both at low speeds and under full load, whenever the driver requires maximum power and performance. The fuel injection system with magnetic valve injectors operating at a pressure of up to 1,800 bar ensures precise dosage of fuel as well as a consistent, low emission combustion process.
The new BMW 520d accelerates to 100 km/h within just 8.1 seconds and has a top speed of 227 km/h or 141 mph (provisional figures). Average fuel consumption in the EU test cycle of 5.0 litres/100 kilometers (47 mpg US) and a CO2 rating of 132 grams per kilometer.
The new BMW 520d comes as standard with an Auto Start Stop function—its debut on the 5 Series.

6-cylinder diesel 525d and 530d. Representing a brand-new generation of straight-six turbodiesels, the 3.0-liter in the 530d features an all-aluminium crankcase, the enhanced turbocharger system with variable turbine geometry, and the latest generation of common-rail fuel injection. Fuel is supplied by means of upgraded piezo injectors now operating at a maximum pressure of 1,800 bar.
The injectors positioned right in the middle and the valves in vertical arrangement ensure a smooth and consistent combustion process, serving to reduce emissions from the engine right from the start.This six-cylinder diesel develops maximum output of 180 kW/245 hp at an engine speed of 4,000 rpm, with peak torque of 540 N·m/398 lb-ft from 1,750 to 3,000 rpm.
This kind of power accelerates the new BMW 530d to 100 km/h in 6.3 seconds and gives the car a top speed of 250 km/h (155 mph). Average fuel consumption in the EU test cycle, in turn, is 6.3 liters/100 kilometers (37 mpg US), with CO2 emissions of 166 grams per kilometer.
In standard trim the new BMW 530d fulfils the EU5 emission standard. Equipped with optional BMW BluePerformance technology available also on this model in conjunction with automatic transmission, the new BMW 530d fulfils the requirements of the EU6 standard not coming into force until 2014.
With BluePerformance technology, the diesel particulates filter and the oxidation catalyst housed in the same unit interact with an NOx storage catalyst for further reduction of NOx in the exhaust gas. Like the diesel particulates filter, the NOx storage catalyst does not require any maintenance or additional operating media throughout the entire service life of the car.
The new BMW 525d is likewise powered by a 3.0-liter straight six of the latest generation. In this model the all-aluminium diesel develops maximum output of 150 kW/204 hp at 4,000 rpm, while maximum torque increased to 450N·m/332 lb-ft is maintained consistently between 1,750 and 2,500 rpm.
The engine accelerates the new BMW 525d from zero to 100 km/h in 7.2 seconds and gives the car a top speed of 236 km/h or 146 mph. Average fuel consumption in the EU test cycle is 6.2 liters/100 kilometers (38 mpg US) with a CO2 emission rating of 162 grams per kilometer.

6-cylinder gasoline 523i, 528i and 535i. Delivering 225 kW/306 hp, the 3.0-liter engine in the BMW 535i is the first engine to combine BMW TwinPower Turbo Technology, High Precision Injection, and variable VALVETRONIC valve management. The turbocharger system applies the TwinScroll principle to separate the ducts of three cylinders at a time both in the intake manifold and in the turbocharger itself.
The engine develops its maximum torque of 400 N·m/295 lb-ft all the way from 1,200 to 5,000 rpm, with maximum output at 5,800 rpm.
The new BMW 535i accelerates from a standstill to 100 km/h in 6.0 seconds, its top speed is limited electronically to 250 km/h or 155 mph. Fuel consumption in the EU test cycle is 8.5 litres/100 kilometers (28 mpg US)), with a CO2 rating of 199 grams per kilometer.
The six-cylinder 3.0-liter power units featured in the BMW 528i and 523i come with a version of High Precision Injection with an even greater focus on efficiency. Stratified charging forms various interacting layers of different fuel/air mixtures within the combustion chamber, the share of gasoline in the mixture decreasing continuously with an increasing distance from the spark plug. A particularly rich and therefore ignitable fuel/air mixture is therefore available only in the direct vicinity of the spark plug. As soon as this mixture is ignited, the leaner layers at a greater distance from the spark plug will also burn in a clean and consistent process.
In the new BMW 528i, this technology provides for maximum output of 190 kW/258 hp at an engine speed of 6,600 rpm and peak torque of 310 N·m/228 lb-ft all the way from 2,600 – 5,000 rpm. Acceleration from a standstill to 100 km/h comes in 6.6. seconds and the top speed of the new BMW 528i is limited electronically to 250 km/h or 155 mph.
This performance goes together with average fuel consumption in the EU test cycle of 7.8 liters/100 kilometers (30 mpg US) and a CO2 rating of 182 grams per kilometer.
The power unit featured in the new BMW 523i delivers maximum output of 150 kW/204 hp at 6,100 rpm and peak torque of 270 N·m/199 lb-ft all the way from 1,500 – 4,250 rpm. The sedan accelerates to 100 km/h in 7.9 seconds and provides a top speed of 238 km/h or 148 mph. Average fuel consumption of the new BMW 523i in the EU test cycle is 7.6 liters/100 kilometers (31 mpg US), with CO2 emissions of 177 grams per kilometer.
Gasoline V8 550i. The top-of-the-range BMW 550i comes with a 4.4-liter V8 featuring BMW TwinPower Turbo Technology and High Precision Injection for maximum output of 300 kW/407 hp between 5,500 and 6,400 rpm. Torque reaches a peak of 600 N·m/442 lb-ft maintained consistently between 1,750 and 4,500 rpm.
The V8 in the new BMW 550i is the only gasoline engine to feature turbochargers and catalytic converters conveniently housed in the V-section between the two rows of cylinders. This ensures particularly short distances between the turbocharger and the intake manifold and, together with the water-cooled intercoolers, gives the V8 an exceptionally spontaneous and direct response.
The BMW 550i accelerates from a standstill to 100 km/h in just 5.0 seconds and offers adequate power reserves also at higher speeds for a continuing process of smooth and dynamic acceleration. Top speed is limited to 250 km/h or 155 mph by the electronic control unit, average fuel consumption of the BMW 550i in the EU test cycle is 10.4 liters/100 kilometers (23 mpg US), with CO2 emissions of 243 grams per kilometer.

Transmissions. Benefiting from dry sump lubrication, the six-speed manual gearbox on the BMW 535i, BMW 525d and BMW 520d has significantly lower drag losses and avoids oil splash losses completely in the interest of even greater efficiency.
The new BMW 530d and the BMW 528i and BMW 523i likewise come with new versions of the six-speed manual gearbox optimized for efficiency with conventional oil supply.
The BMW 550i comes as standard with the new eight-speed automatic transmission featured for the first time in the BMW 760i twelve-cylinder Luxury Performance Sedan, which is also available as an option for all other variants of the new BMW 5 Series Sedan. When fitted, this makes the new BMW 520d the first car in the world to combine a four-cylinder power unit with an eight-speed automatic transmission.
As yet a further option the new BMW 5 Series Sedan is also available with a Sport Automatic variant of the eight-speed transmission allowing manual selection of gears by means of shift paddles on the steering wheel.
The eight-speed automatic transmission features an innovative gearset configuration, with four single gearsets and five shift units interacting to provide the eight forward gears and one reverse gear. The arrangement of these components—the first on an eight-speed automatic transmission—ensures that only two of five clutches are moved along open in each gear, significantly reducing drag losses in comparison with the automatic transmissions currently in the market.
With the number of gears being increased to eight, gear increments when shifting are smaller than before despite the greater range between the lowest and highest transmission ratio. While accelerating, the harmonious shift in transmission ratios ensures a particularly smooth and steady increase in speed, short reaction and gearshift times versus six-speed automatic transmission providing even greater comfort and driving dynamics all in one.
A further advantage is that only one clutch has to be opened when shifting up or down, while direct detection of the right gear lane enables the driver to shift the transmission by more than two gears at a time, again with extremely short reaction and gearshift times.
The process of shifting down from eighth to second gear when accelerating spontaneously (kick-down) again comes with a direct gearshift opening up only one clutch.
EfficientDynamics. BMW EfficientDynamics technologies are featured as standard in appropriate combinations on each model, with features such as Brake Energy Regeneration, a gearshift point indicator, active air flap control, and on-demand operation of ancillary units including a detachable a/c compressor.
Intelligent lightweight construction, finally, is ensured by features such as the doors, engine compartment lid, front side panels and suspension components made of aluminum.
Brake Energy Regeneration including a recuperation display, is standard on the new 5 Series. Brake Energy Regeneration ensures intelligent management of energy flow in the car, concentrating the generation of electric power for the on-board network on overrun and the application of the brakes. This takes the usual load off the engine and ensures highly efficient generation of electric energy largely without any additional consumption of fuel. As long as the engine is pulling the car, on the other hand, the generator is generally disconnected.
In the new BMW 5 Series Sedan the instrument cluster is supplemented by a recuperation display. This graphic display next to the current consumption indicator at the bottom of the rev counter presents the generation of electric power in overrun and while applying the brakes, the blue arrow being activated as long as Brake Energy Regeneration feeds energy generated without the consumption of fuel into the on-board network.
The new BMW 5 Series Sedan is the first car in its segment to feature EPS Electric Power Steering . This steering system enhances both the precision and comfort of the steering process, at the same time ensuring handling. Contrary to conventional mechanical/hydraulic systems, steering assistance is provided in this case by an electric motor activated only when assistance is necessary or desired by the driver. When driving in a straight line or when taking a bend with a steady steering angle, the consumption of energy is reduced to zero.
EPS comes as standard on the new BMW 5 Series Sedan with Servotronic gearing steering assistance to the speed of the car. When parking and steering at low speeds, for example, the driver hardly has to make any effort, while at higher speeds power assistance is intentionally reduced for optimum contact to the road and in the interest of well-balanced directional stability.
EPS also eliminates bumps coming from the steering and any other adverse vibrations very effectively. And by evaluating dynamic driving signals in an appropriate process, EPS gives the driver authentic steering feedback particularly under very dynamic driving conditions.
BMW ConnectedDrive. The driver assistance systems offered for the first time in the context of BMW ConnectedDrive include a Parking Assistant, Surround View, collision warning with application of the brakes in conjunction with Active Cruise Control plus Stop & Go, and a new Speed Limit Device. Further features also available are Lane Change Warning, Lane Departure Warning, Speed Limit Info, a Head-Up Display, BMW Night Vision with detection of individual persons, and a back-up camera.
US offerings. At launch, the new BMW 5 Series Sedan for the US will be available with one V-8 and one inline-6 gasoline engine: the 550i and the 535i. Later, the BMW 528i will debut.
