With the BMW X4 M40i, BMW M GmbH once again demonstrates its years of
expertise in the construction of exclusive sporty automobiles. This automobile impresses
with an outstanding combination of unadulterated dynamics, comfort and everyday
M Performance TwinPower Turbo inline 6-cylinder petrol engine
The M Performance TwinPower Turbo inline 6-cylinder petrol engine combines impressive performance with thrust that is maintained well into the high rev range, thus setting new standards in the vehicle segment of the BMW X4. The power unit with a forged steel crankshaft provides revving power that is typical for BMW M: Between 1,350 and 5,250 rpm, a maximum torque of 465 Nm is available. The 3.0-litre engine achieves its maximum output of 265 kW (360 hp) between 5,800 and 6,000 rpm. The BMW X4 M40i reaches 100 km/h from a standing start in just 4.9 seconds. This impressive performance is achieved with combined fuel consumption of 8.6 litres per 100 km and CO2 emissions of 199 g/km, demonstrating an exceptional balance of dynamics and efficiency – and once again highlighting the exceptional engineering know-how of BMW.
The specific exhaust system was optimised to ensure a charismatic, individually regulated sound and ideal exhaust back pressure. It has an intelligent valve control and, thanks to the Black Chrome tailpipe finisher on both sides, is recognisable in an instant.
Typical M Performance driving dynamics
Thanks to a wealth of adaptations, the BMW X4 M40i impresses with driving dynamics that only M Performance automobiles can offer. Comprehensive fine-tuning of the suspension elevates the lateral and longitudinal dynamic characteristics to a whole new level, thereby meeting the requirements of even the sportiest drivers. Many systems were adapted for the typical M Performance driving dynamics, including the rear-biased BMW xDrive as well as the electronically controlled damper system and variable sport steering.
The standard-feature 8-speed Steptronic Sport transmission with gearshift paddles on the steering wheel enables both more comfortable and extremely sporty gearshifts as well as improved downshift spontaneity. The drive train is connected sportily and directly, which, together with standard-feature Launch Control, ensures lightning-quick starts. Conversely, large brake discs on the front axle and optimised brake pads on all wheels guarantee outstanding stopping power, even in the sportiest driving situations.
The M genes in the design of the BMW X4 M40i allow the vehicle to exude full-blown dynamics as soon as you set eyes on it. The sporty look is characterised by a number of individual and highly exclusive details. This is provided by the components of the standard-feature M Sport package, including specific adaptations of the front and rear bumper.
Even when viewed from a distance, the BMW X4 M40i stands out in a crowd, with the exclusive look of the 20" light alloy wheels Double-spoke style Bicolor making it instantly recognisable. Available in the 8.5 J x 20 (front) and 10 J x 20 (rear) format, these wheels have ultra-high-performance tyres. Special design elements in Ferric Grey in the air inlets of the wide front apron and the kidney grille slats add to the presence of the vehicle. Striking sporty exterior mirror caps, which are also available in Ferric Grey, are irresistible – even to the wind. Twin tailpipe finishers in Black Chrome add an additional touch of dynamics to the powerful rear of the vehicle.
Inside the BMW X4 M40i, numerous features help to create a sporty ambience. Top-quality materials and an M specific design with an eye for detail further increase driving pleasure. On the door sill finishers, the “X4 M40i” lettering catches the eye immediately. The decor trims, which are available in Aluminium and several other variants, boost the sporty-technical look. A further example is the electronic model designation under the rev counter. The M leather steering wheel is perfectly contoured for your hands, enabling the vehicle to be controlled with the greatest precision. And when cornering, the perfect ergonomics of the sport seats for driver and front passenger provide lateral stability and excellent comfort.
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.
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.
8-SPEED STEPTRONIC SPORT TRANSMISSION WITH GEARSHIFT PADDLES.
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.
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.
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. 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 ECO PRO Mode reduces fuel consumption by up to 20 percent. 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 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. 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. In Sport mode, the car responds more directly, allowing for a sportier driving style.
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.
