The BMW X4

The Driving Dynamics & Efficiency of the BMW X4.

One nudge of the accelerator pedal and the BMW X4 enters a world of its own. The eight-speed Steptronic sport transmission utilises the potential of the engines to the full: The BMW X4 xDrive35d completes the 0 to 100 km/h sprint in just 5.2 seconds. The intelligent four-wheel drive system BMW xDrive transfers power to the street with outstanding traction. Other standard features include variable sport steering and Performance Control.  

BMW X4 Variable Sport Steering

VARIABLE SPORT STEERING.

The variable sport steering with Servotronic enables a direct and agile driving style with less physical effort when steering. 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. This significantly increases agility and improves handling in sharp turns, along narrow roads or when making sudden swerves while using a particularly sporty driving style. It also increases comfort when parking, turning and manoeuvring. For small steering angles, the system provides excellent directional stability and a very high degree of steering precision.

BMW X4 Dynamics

DRIVING DYNAMICS.


With its specially constructed chassis, high-performance engines and an array of top-quality standard equipment, the BMW X4 offers impressive agility.

The Performance Control distributes engine and braking control to the individual wheels when turning. Because the outer wheels have to move a longer distance than the inner wheels when turning, the BMW Performance Control intervenes by means of engine output and controlled braking: The outer wheels get more power while the inner wheels get less, maximising traction on each of the wheels. This means that the vehicle practically turns itself, thus increasing driving safety and comfort.

The 8-speed Steptronic Sport transmission adapts to suit individual driving style. It is perfect for everything from comfortable cruising through to a very dynamic drive.

In addition to automatic gear selection, it is of course possible to shift gears manually at any time. Shifting is accomplished using the shortened gear selector lever or gearshift paddles on the steering wheel.

In Sport mode, the gear shifts are configured for maximum performance. The particularly fine graduation of the eight gears optimises the acceleration process and the engine is always maintained at a level of performance that guarantees the ultimate in power and efficiency. Maximum acceleration is made possible by Launch Control: This feature shifts automatically in order to make use of the motor's optimum rpm range.

When travelling at high speeds, the additional eighth gear reduces the required engine speed, thereby also reducing the fuel consumption and engine noise. This is also where the newly developed, highly effective converter clutch comes into play. The 8-speed Steptronic Sport transmission delivers maximum efficiency and incredibly smooth gear shifts.

The chassis is specially tuned to suit the BMW X4 and impresses with excellent road-holding, perfect handling and top-class agility – and, at the same time, guarantees comfort at all times. With Dynamic Damper Control with Comfort, Sport and Sport+ modes, the driving characteristics can be adapted individually. The wide track of the BMW X4 and its five-arm rear axle also enable high-speed cornering with minimum roll.

Dynamic Damper Control.

 

The Dynamic Damper Control makes it possible to ideally adjust the damper characteristics to suit any given driving situation, improving comfort and driving dynamics. In addition to the standard Comfort setting, which minimises bumps and other unpleasant vehicle movements, there are two other programs available: the Sport and Sport+ modes. In these modes, the dampers are automatically tightened to allow for a sportier driving style.

BMW X4 xDrive

BMW xDrive.

 

The intelligent BMW xDrive four-wheel drive system adapts perfectly to even the most challenging road surface conditions, ensuring outstanding traction at all times. With xDrive and Dynamic Stability Control (DSC), the vehicle remains directionally stable and on track. Split second response times allow xDrive to distribute drive power flexibly between the two axles for optimum grip. In this way, xDrive combines the advantages of all-wheel drive – traction, directional stability and safety – with classic BMW agility.

A clear message even in difficult situations: xDrive Status shows the big picture. When driving over rough terrain, the driver has access to information relevant to off-road driving both on the instrument panel and in the central Control Display. In addition to an easily readable compass for orientation (only in conjunction with Navigation system), the longitude and transverse slope of the vehicle as well as the current steering lock angle are also shown – not only numerically, but also with a graphic 3D display of the car itself.

BMW X4 Drive Performance Control

DRIVING EXPERIENCE CONTROL.


Driving Experience Control lets the driver choose between the Comfort mode, for standard engine and transmission settings, the ECO PRO Mode, geared towards efficiency, and the Sport mode, which enables even more dynamic driving.

Sport mode.

Take it to the next level: When the Sport mode on the Driving Experience Control is switched on, the engine and suspension of the BMW will react even more directly for a more dynamic drive.

The Sport mode is activated with the Driving Experience Control switch in the centre console. This activates a pre-defined configuration of engine and suspension settings, which, depending on the equipment fitted, are significantly more dynamic than the standard settings. For example, the engine becomes even more responsive. For models with the Steptronic transmission, the timing of the gearshifts is made considerably sportier. In Sport mode, the current output (kW) and contingent torque (Nm) are also shown in the central display. This feature is only available in conjunction with the Navigation system Professional. In conjunction with the adaptive suspension, the suspension becomes more agile. If the BMW is equipped with variable sport steering, the power steering is reduced, giving the driver an even more direct steering experience.

BMW EfficientDynamics in the BMW X4.

Restraint is not an attribute usually associated with the BMW X4 – with one notable exception: fuel consumption and CO2 emissions. The latest BMW EfficientDynamics technologies and an aerodynamic design guarantee low values without any compromise in performance and dynamics.

The BMW X4 Aerodynamics

Aerodynamics.

 

The entire vehicle design is testament to the BMW EfficientDynamics philosophy. Every BMW boasts excellent air resistance figures thanks to a range of mutually optimised aerodynamic elements, which in turn has a positive effect on efficiency and fuel consumption. For example, the flat undercarriage cover with engine compartment and rear axle shield improve the car's aerodynamics. These new casing elements are not only highly advantageous in terms of aerodynamics: they also improve sound insulation and provide greater protection from rust. Further innovations in aerodynamics include the defined rear spoiler lip and the aerodynamically optimised exterior mirrors. The latter improve the acoustics in addition to the aerodynamics and prevent the side windows from getting as dirty.

The BMW X4 Lightweight construction

Intelligent Lightweight Construction.


A wide range of high-tech materials are used in the construction of the BMW X4: lightweight aluminium, high-strength steel, state-of-the-art plastics and magnesium.

This intelligent lightweight construction reduces the weight of the vehicle, makes the car body exceptionally rigid, enhances passive safety and improves dynamics.

ECO PRO Mode.


The ECO PRO Mode helps drivers to reduce their fuel consumption by up to 20 percent, depending on their driving style. The "coasting" function (only available with Steptronic transmission), Route-Ahead Assistant and ECO PRO Route (only available with Navigation system Professional) further help to conserve fuel. The fuel-efficient ECO PRO Mode intelligently adjusts the characteristics of the accelerator pedal and transmission, as well as the heating/air conditioning settings
The "coasting" function allows the vehicle to coast along the road at up to 160 km/h when the driver takes his or her foot from the gas without braking.

When used with Active Cruise Control, in ECO PRO Mode the vehicle accelerates up to the desired speed more efficiently after braking.

The Route-Ahead Assistant uses the navigation system to assess local road conditions and give tips in advance. If there is a speed limit change around the next curve, the system advises the driver to slow down before turning.

ECO PRO Route also helps to ensure efficient use of fuel. It suggests an efficiency-optimised route that takes into account the volume of traffic, individual driving style and local conditions.

BMW X4 EfficientDynamics technologies

Energy management. 


The intelligent energy management in the BMW X4 is provided by a number of standard-feature BMW EfficientDynamics technologies, including the Optimum Shift Indicator, the Auto Start-Stop function, Electric Power Steering and Brake Energy Regeneration. The interplay between these technologies ensures the sustainable mobility of tomorrow − today.

Optimal, perfectly-timed gear changes can help save fuel, particularly in urban environments and over long distances. Optimal gear changes, less fuel consumption – the engine’s electronics system identifies the most efficient gear based on the driving situation and engine speed. An arrow lights up in the Info Display to show when it would be more efficient to shift into a higher or lower gear. The system also recognises when the car is accelerating quickly and will delay its recommendation accordingly until the engine speed has increased. Comparative tests have shown that vehicles with the Optimum Shift Indicator use around four percent less fuel.

The Automatic Start/Stop function makes sure that fuel is only used when the car is actually driving. When the vehicle comes to a temporary standstill, for example 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 idling and the car brakes to a complete standstill (Steptronic transmission).

A signal in the Info Display indicates that the Automatic Stop/Start function is active. As soon as the foot is taken from the brake (Steptronic transmission), 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.  

Every time the driver steers, energy is consumed. But why should energy be consumed when the wheel is not being turned? BMW Electric Power Steering is only active when it is needed. Unlike conventional hydraulic steering systems, BMW EPS only uses energy when the wheel is actively being turned. When the steering wheel is static – e.g. when driving straight ahead along a motorway at high speed – the electric motor is inactive.

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: reduced fuel consumption and increased performance – classic BMW EfficientDynamics.
