UNMERCIFULLY DYNAMIC. UNCOMPROMISINGLY EFFICIENT.

BMW EfficientDynamics in the BMW 2 Series Coupé.

The new 2 Series Coupé can’t get enough: more performance, more sportiness, more to amaze. But it’s also the master of superlatives when it comes to less: less consumption and fewer emissions. Whether in ECO PRO Mode, Brake Energy Regeneration or Automatic Start/Stop function, the coupé knows how to make expert use of the intelligent BMW EfficientDynamics measures. And thanks to its aerodynamic design, the BMW 2 Series Coupé cuts a very fine figure while at it.[1]

ECO PRO MODE.

ECO PRO Mode helps drivers reduce their fuel consumption by up to 20 percent, depending on their driving style – according to an internal BMW fuel consumption study. The additional functions, coasting (with Steptronic transmission only), Route-Ahead Assistant and ECO PRO Route (both with Navigation System Professional only), deliver even more savings potential.
The coasting function disconnects the drive train from the engine, causing the vehicle to "coast" without additional power input. This occurs as soon as the driver takes his or her foot off the accelerator between the speeds of 50 and 160 km/h without braking and the Route-Ahead Assistant does not detect any change in the speed limit.
Using data from the navigation system, the Route-Ahead Assistant is able to recognise curves, built-up areas, speed limits and motorway exits, and gives the driver tips to slow down in advance.
Depending on your driving and the traffic and road conditions, the ECO PRO Route displays the most efficient route. The on-board computer shows what percentage of fuel can be saved by using the ECO PRO Route.

AERODYNAMICS.

The entire vehicle design is a testament to the BMW EfficientDynamics philosophy. Its streamlined silhouette makes it incredibly aerodynamic. The front apron is a prominent design feature that embodies the BMW EfficientDynamics philosophy. The integrated Air Curtain channels air through two vertical air inlets and along the front wheel arches. The accelerated air flow creates a kind of "curtain" on the outer side of the wheels. These innovative technologies reduce turbulence and air resistance, which in turn significantly reduces fuel consumption. The flat undercarriage cover, which also shields the engine compartment and rear axle, is an additional detail that greatly improves the car’s aerodynamics. These new trim elements are not only highly advantageous in terms of aerodynamics: they also improve sound insulation and provide greater protection from rust.

AUTOMATIC START/STOP FUNCTION.

The Automatic Start/Stop function makes sure that fuel is only used when the car is actually driving. While waiting at traffic lights or in stop-and-go traffic, the Automatic Start/Stop function saves fuel by switching off the engine as soon as the car is idle and the foot has been taken off the clutch (manual transmission), or when the driver brakes to a complete standstill (Steptronic transmission).
A signal in the Info Display indicates that the Automatic Start/Stop function is active. As soon as the driver shifts into gear (manual transmission) or takes his foot off the brake (Steptronic transmission), the engine immediately switches itself back on.
The Auto Start-Stop function never compromises driving comfort and safety, as it remains inactive if the engine has not reached its ideal running temperature, the interior has not yet been sufficiently heated/cooled, if the battery level is too low or if you are turning the steering wheel.
A central control unit restarts the engine if required, even when the car is at a standstill – for example, if the car starts to roll forward or if the windscreen becomes foggy. The Automatic Start/Stop function can be switched off at any time with the push of a button.

BRAKE ENERGY REGENERATION.

Every time you brake, kinetic energy is generated, and until recently, this energy has gone unused. Brake Energy Regeneration takes advantage of this long-overlooked potential. It harnesses the coasting energy that is generated whenever the driver brakes or takes their foot off the accelerator and turns it into electricity. This electricity is then used to charge the car battery. The intelligent energy management system means that the alternator no longer needs to run permanently, which reduces the strain on the generator. The result is reduced fuel consumption and increased performance – classic BMW EfficientDynamics.

8-SPEED STEPTRONIC TRANSMISSION.

The 8-speed Steptronic transmission sets new benchmarks in comfort and dynamic performance and is a key element of BMW EfficientDynamics. The unusually fine increments between gears facilitate optimum power delivery at all speeds. This reduces fuel consumption significantly, while allowing the driver to enjoy increased sportiness and dynamic performance. At high speeds in particular, the additional gears reduce engine speed, in turn decreasing both fuel consumption and engine noise.
The converter clutch also helps – even if the car is changed to the manual mode. In combination with the fast engine speed transitions and the precise transmission tuning, it provides a very high level of shift comfort and reduces noise considerably.
Thanks to the 8-speed Steptronic transmission from BMW EfficientDynamics, it is now possible to actively boost performance in vehicles with the new Predictive Drive Train via the Driving Experience Control. In the "Sport" mode, the transmission management uses data from the navigation system to deliver a level of responsiveness that is even more dynamic and spontaneous based on route characteristics. As suggested by its name, the "Comfort" mode offers a comfort-oriented shift programme with fewer shifts.

OPTIMUM SHIFT INDICATOR.

Optimal and perfectly-timed gear changes can help save fuel, particularly in urban traffic and over long distances. Optimal gear changes, less fuel consumption – the engine’s electronics system identifies the most efficient gear, based on road conditions and engine speed. An arrow lights up in the Info Display to show you when it would be more efficient to shift into a higher or lower gear. The system also recognises when you are accelerating fast, and will delay its recommendation accordingly until the engine speed is back up. In manual shifting mode, drivers with a Steptronic transmission also receive relevant shifting suggestions. Comparative tests have shown that vehicles with the Optimum Shift Indicator use around four per cent less fuel.
