BMW 3 Series - Milestones (2): Driving pleasure through the course of time - from the first McPherson front suspension to Active Steering and DSC: milestones in BMW 3 Series chassis development.

With the most modern suspension in its segment, the fifth model generation of the BMW 3 Series also sets standards in driving pleasure and agile handling. The unique combination of a double-joint tension-rod suspension at the front and a five-link rear axle, a consistent lightweight construction incorporating numerous aluminium components, highly efficient and likewise weight-optimised brakes as well as an energy-saving electro-mechanical steering system are all proof of the BMW 3 Series' technological lead.

Munich. With the most modern suspension in its segment, the fifth model
generation of the BMW 3 Series also sets standards in driving pleasure and
agile handling. The unique combination of a double-joint tension-rod suspension
at the front and a five-link rear axle, a consistent lightweight construction
incorporating numerous aluminium components, highly efficient and likewise
weight-optimised brakes as well as an energy-saving electro-mechanical steering
system are all proof of the BMW 3 Series' technological lead.

Together with power transmission to the rear wheels and even axle load
distribution, the advanced suspension technology forms the basis for the BMW 3
Series' fascinating handling characteristics. This concept has a long
tradition. As early as 1975, the first BMW 3 Series impressed with sporty road
performance that enabled the driver to maintain complete control of the saloon
even when driving it to its physical limits. The claim of that time to more
driving fun in the medium class segment and to combine it with exemplary
quality and a high degree of safety still characterises a BMW 3 Series to this
very day.

Driving fun in the medium class segment: the BMW 3 Series remains the benchmark
In this way, a new vehicle category was created 33 years ago. In the meantime,
invoking sporting characteristics seems to be the order of the day amongst
almost all rivals within the BMW 3 Series' highly competitive segment. The
continuing success of the BMW 3 Series provides the incentive to do so -
nevertheless, the original remains unrivalled. Only the BMW 3 Series combines
all prerequisites for maximum driving pleasure - from the standard drivetrain,
an even weight balance between front and rear axle to a consistently superior
suspension technology.

In addition to the unique conceptual harmony, the innovative power of BMW
engineers has contributed towards maintaining and further extending the
technological lead. With each generation of the BMW 3 Series, further
innovations in wheel suspension, spring technology, damping, steering and
braking systems were introduced. The BMW 3 Series regularly profited from
innovations originally developed for vehicles positioned in higher segments.

Consequently, it also became a forerunner of advancement in the field of
suspension technology. In the course of its history, the BMW 3 Series has
consistently and most convincingly reinterpreted the principle of driving
pleasure, that was already applicable 33 years ago, right up to the latest
generation which is more than just the result of outstanding engineering
skills. Consistent lightweight construction enhances agility through a
reduction of unsprung masses, unmatched precision steering and the versatile,
perfectly balanced stability control systems convey a maximum degree of
superiority even in particularly demanding driving situations. In the exclusive
circle of premium vehicles within its class, the BMW 3 Series satisfies more
than ever before the expectations of drivers for whom the active driving
experience is the crucial factor when making a purchase decision.

CO2 emission information.

The following applies to consumption figures for vehicles with new type approval, September 2017 onward: The figures for fuel consumption, CO2 emissions and energy consumption are obtained in accordance with the specified measuring procedure (EC Regulation No. 715/2007), as issued and amended. The figures are for a basic-version vehicle in Germany. The bandwidths allow for differences in the choice of wheel and tire sizes and items of optional equipment and can be changed by the configuration.

Obtained on the basis of the new "Worldwide harmonized Light vehicles Test Procedure" (WLTP), the figures are converted back to the "New European Driving Cycle" (NEDC) for the sake of comparability. Values other than those stated here may be used for the purposes of taxation and for other vehicle-related duties relating to CO2 emissions.

More information about official fuel consumption figures and the official specific CO2 emissions of new passenger cars can be obtained from the "guideline on fuel consumption, CO2 emissions and current consumption of new passenger cars", available here: https://www.dat.de/co2/.
