BMW EFFICIENT DYNAMICS TECHNOLOGIES.
Get more out of every litre of fuel with BMW EfficientDynamics and benefit from better performance, greater efficiency and a heightened driving experience. Technical innovations that lower fuel consumption while simultaneously increasing driving pleasure mean that pure dynamics come standard in every BMW.
BMW TWINPOWER TURBO ENGINES.
Thanks to BMW TwinPower Turbo technology, the innovative new generation of BMW petrol and diesel engines from the BMW EfficientDynamics engine range can deliver an agile performance and excellent responsiveness even at low revolutions per minute, all while being exceptionally fuel efficient and low in emissions.
8-SPEED AUTOMATIC TRANSMISSION STEPTRONIC.
The 8-speed Automatic Transmission Steptronic sets new benchmarks in comfort and dynamic performance and is a key element of BMW EfficientDynamics. The unusually fine increments between gears produce optimum power delivery at all speeds.
This reduces fuel consumption significantly, while allowing the driver to enjoy increased sportiness and dynamic performance. The engine speed is reduced, particularly at high speeds, which in turn reduces both fuel consumption and engine noise.
The converter clutch contributes, even if the car is in manual mode. Together with the fast engine speed transitions and precise transmission tuning, it guarantees incredibly smooth gearshifts.
Integrated functions such as predictive drive train and the constant monitoring of the vehicle's movements and the traffic situation considerably affect the way the transmission shifts gears. Regardless of the current driving mode, the system always selects the most suitable gear. The transmission control unit is linked to the navigation system, so depending on the route, the predictive drivetrain switches between a more athletic, responsive setting (SPORT mode) and a more comfortable setting with fewer gear shifts (COMFORT mode).
The BMW M140i is synonymous with pure driving pleasure and exceptional driving dynamics. Its high-revving BMW M Performance TwinPower Turbo inline 6-cylinder petrol engine with a 3.0-litre capacity generates 250 kW at 5,500 and accelerates the car from 0 to 100 km/h in just 4.8 seconds. What's more, it produces an incredibly powerful engine sound, as well as tremendous thrust whenever it's needed thanks to 500 Nm of torque. The chassis sits 10 millimetres lower and has firmer, more athletic damper and suspension characteristics that are unique to the M models and which transfer the full force of the engine safely to the road. The M Sport brake with blue brake callipers and the M logo ensures maximum braking power, even when the BMW is pushed to its limits. The superbly responsive variable sport steering with M-specific characteristics gives the driver precise feedback for safe handling. The M Aerodynamics package with specific air inlets at the front, exclusive 18" M light alloy wheels and two tailpipes round off the exterior equipment features.
In the interior, M door sill finishers, M sport seats, an M leather steering wheel, and M-specific instruments all demonstrate the car's dynamic pedigree.

Variable sport steering
The variable sport steering with Servotronic creates a direct and agile steering response and ensures less physical effort is required to turn the wheel. It reacts to the angle of the steering wheel independently from the current speed with various steering ratios. This reduces the steering movement required when steering at particularly large angles. It features speed-dependent, variable power steering. This significantly increases agility and improves handling when driving dynamically through sharp bends and corners, or when swerving to avoid obstacles. It also makes parking, turning and manoeuvring easier. For small steering angles, the system provides excellent directional stability and a very high degree of steering precision.
M Sport suspension
The M Sport suspension is characterised by sport suspension settings, and includes a chassis lowered by around 10 millimetres. It features shorter suspension springs and tighter damper settings, as well as harder stabilisers. Together these result in even more direct settings that facilitate a particularly dynamic driving style.
Adaptive M suspension
The Adaptive M suspension is set ten millimetres lower, further increasing the vehicle's full dynamic potential. The driver can adjust the driving characteristics to enable whichever driving style is most appealing at the time – from comfortable to extremely athletic. Whichever setting is chosen, the Adaptive M suspension's electrically controlled dampers calibrate to suit the road conditions within fractions of a second. The system also uses numerous sensors that measure wheel vibrations, as well as vehicle speed, in order to achieve optimal damping and vehicle safety.
COMFORT mode can be selected for relaxed travelling. SPORT mode enables a distinctly athletic suspension setting with noticeably tighter damper settings. For extremely dynamic driving, SPORT+ mode is the best choice. The DTC function (Dynamic Traction Control) is activated, which allows more wheel-slip on the drive wheels, for athletic driving that pushes the limits of the car's dynamics. However, the DSC function isn't completely disabled. It intervenes much later, within the limits of what is physically possible and safe, in order to stabilise the vehicle.
ECO PRO MODE.
The 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 coasting function (only in conjunction with Automatic Transmission Steptronic), the route-ahead assist (only in conjunction with Navigation System Professional) and ECO PRO route (only in conjunction with Navigation System Professional or Business) make it possible to save a further 5 percent.
The coasting function decouples the drive train from the engine and the vehicle rolls without any engine resistance. The car "coasts" when the driver takes their foot off the accelerator between 50 and 160 km/h and does not apply the brakes. If needed, the route-ahead assist can intelligently suppress coasting.
ECO PRO route
ECO PRO route shows the most efficient route based on the traffic situation, driving style and local conditions. The on-board computer displays the percentage of fuel that can be saved by driving along the route selected by ECO PRO route.
INTELLIGENT ENERGY MANAGEMENT.
The intelligent energy management in the BMW 1 Series is provided by a number of standard-feature BMW EfficientDynamics technologies, including the Automatic Start/Stop function, Brake Energy Regeneration, Electric Power Steering and Optimum Shift Indicator. The interplay between these technologies ensures sustainable mobility and maximum efficiency.
Automatic Start/Stop Function
The Automatic Start/Stop function makes sure that fuel is only used when the car is actually being driven. When the vehicle comes to a temporary standstill, for example at robot or in stop-and-go traffic, the Automatic Start/Stop function saves fuel by switching off the engine as soon as the car is idling and the foot is off the clutch (manual transmission), or when the car brakes to a complete standstill (Automatic Transmission Steptronic). A signal in the Info Display indicates that the Automatic Stop/Start function is active. As soon as the clutch is pressed (manual transmission) or the foot taken from the brake (Automatic Transmission Steptronic), the engine turns itself back on automatically.
The Automatic 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 the steering wheel is being turned. 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 the brakes are hit, kinetic energy is generated and until recently this energy went 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 his or her 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 constantly, which reduces the strain on the generator. The result is reduced fuel consumption and increased performance. In other words, classic BMW EfficientDynamics.
Electric Power Steering
Electric power steering optimally adjusts the steering support to the current speed. This results in direct, precise steering behaviour at high speeds and effortless manoeuvrability when parking. The steering only consumes energy when it is really necessary. This saves fuel and reduces emissions.
Instead of a hydraulic pump, it relies on an electric motor. In conventional systems, this pump must be constantly powered by the engine, but this electric support only runs when the steering wheel is being moved. When driving straight ahead or maintaining the same steering angle (e.g. on long bends), the electric motor is not active and does not consume any energy. By flexibly adjusting the steering support to match the current driving situation and speed, steering comfort is improved.
Optimum Shift Indicator
Perfectly timed gear shifts can significantly help save fuel, particularly in urban traffic and over long distances. Optimised gear shifts equal lower fuel consumption. The engine electronics calculate the most efficient gear for each driving situation and engine speed. An illuminated arrow symbol appears in the Info Display whenever the vehicle could be operating more efficiently in a higher or lower gear. The system also recognises quick acceleration, and will delay its recommendation accordingly until the engine speed has increased. BMW internal comparative tests have shown that vehicles with the Optimum Shift Indicator use around 4 percent less fuel.
