New range of engines: All petrol and diesel versions with turbocharger and direct injection.
A completely revised engine range ensures that the BMW X5 will continue to strengthen its leading role as the most dynamic vehicle in its segment. The choice of petrol engines now comprises a V8 and a straight six-cylinder power unit, both of which feature BMW TwinPower Turbo technology and direct fuel injection. In addition, two variants of the new generation of the BMW straight six-cylinder diesel engine are available. Both all-aluminium power units are turbocharged and utilise the latest Common Rail direct injection technology.
All power units available for the BMW X5 set the benchmark in sporting power development and efficiency in their respective engine class. They comply with the EU5 emission standard in Europe and with ULEV II in the USA respectively. Drive power of each engine is transferred via the standard eight-speed automatic transmission, whose outstanding efficiency also contributes towards a reduction of fuel consumption and emission levels.
All this is supplemented by BMW EfficientDynamics measures, the combination of which is adapted to suit each model. This technology, which also comes as standard, includes brake energy regeneration and demand-controlled ancillary components including the electric coolant pump, the electric power-steering pump, the map-controlled oil pump and the disengageable air conditioning compressor. Furthermore, the measures comprise intelligent lightweight construction, low-rolling resistance tyres and optimised aerodynamics including active air vent control. As a result of the comprehensive drive technology innovations and the consistent implementation of BMW EfficientDynamics, all versions of the new BMW X5 offer a ratio between vehicle performance and fuel consumption that is unrivalled in their respective competitive segments.

Petrol engines: Significantly increased output thanks to  BMW TwinPower Turbo.
Due to its V8 engine featuring BMW TwinPower Turbo technology and High Precision Injection, output of the new BMW X5 xDrive50i has increased by 39 kW compared with the predecessor model. The unique 4.4 litre engine, the turbochargers of which are located inside the V-section between the cylinder banks, develops an output of 300 kW/407 bhp within an engine speed range of 5,500 to 6,400 rpm. Maximum torque is at 600 Nm between 1,750 and 4,500 rpm. The extremely spontaneous and fascinatingly high-revving V8 engine offers outstanding sporting performance and is at the same time the most efficient engine of its kind worldwide. The BMW X5 xDrive50i accelerates from a standstill to 100 km/h in 5.5 seconds, reaching its top speed at 250 km/h. Average fuel consumption according to the EU test cycle is 12.5 litres/100 km. The CO2 emission level is 292 grams/km.
Likewise, the second petrol engine variant of the new BMW X5 is characterised by significantly improved performance and impressive efficiency.
The BMW X5 xDrive35i features the first straight six-cylinder to combine BMW TwinPower Turbo technology, direct petrol injection (High Precision Injection) and VALVETRONIC variable valve control.
Its supercharging system where – adhering to the Twinscroll principle – the ducts of three cylinders at a time are separated from one another both in the exhaust manifold and the turbocharger, and the further developed VALVETRONIC system lend the 3-litre power unit its fascinatingly spontaneous response behaviour. With 225 kW/306 bhp at 5,800 rpm the engine surpasses its predecessor’s maximum output by 25 kW. Maximum torque of 400 Nm is available between 1,200 und 5,000 rpm. The new BMW X5 xDrive35i sprints from 0 to 100 km/h in 6.8 seconds, top speed being 235 km/h. The significantly increased output is combined with an average fuel consumption reduced to 10.1 litres/100 km in the EU test cycle and a CO2 emission level of 236 grams/km.

New generation of diesel engines in two output categories.
The diesel engines available for the new BMW X5 also originate from a new generation of power units. An all-aluminium construction, the latest Common Rail direct injection technology with piezo injectors and a turbocharger provide both 3-litre straight six-cylinder engines with impressive power, awesome running refinement and unparalleled efficiency. A further reduction in weight compared to each of their predecessors additionally enhances the agility of the diesel engine variants that are on offer for the BMW X5.
Above all, the new BMW X5 xDrive40d is characterised by exceptionally high performance qualities. Thanks to BMW TwinPower Turbo technology and Common Rail direct injection, its power unit, which was first presented in the BMW 740d luxury saloon, delivers a maximum output of 225 kW/306 bhp at 4,400 rpm and a maximum torque of 600 Nm available between 1,500 and 2,500 rpm. Torque of 450 Nm is already achieved at an engine speed of  1,000 rpm. More than 90 percent of maximum output is available within a range of 3,500 to 5,000 rpm. The new diesel has a maximum engine  speed of 5,600 rpm.
The supercharging technology featured by the new high-performance diesel engine adheres to the Variable Twin Turbo principle. This means that initially, just above idling speed, a small charger is activated, with an additional larger charger being activated when higher torque is required. Spontaneous and consistent accelerating power allows the BMW X5 xDrive40d to sprint from 0 to 100 km/h in 6.6 seconds. Top speed is 236 km/h. Exceptionally sporty development of power is coupled with impressive efficiency. This is mainly due to the Common Rail technology, operating at a maximum pressure of 2,000 bar and guaranteeing an extremely accurately regulated fuel supply. The  BMW X5 xDrive40d has an average fuel consumption of 7.5 litres/100 km in the EU test cycle and a CO2 emission level of 198 grams/km.
The second diesel variant in the model range is the new BMW X5 xDrive30d.
Its straight six-cylinder engine is supercharged and has a variable turbine geometry and Common Rail direct injection operating at a maximum pressure of 1,800 bar. The engine generates its maximum output of 180 kW/245 bhp at 4,000 rpm, producing its maximum torque of 540 Nm between 1,750 and 3,000 rpm. The new BMW X5 xDrive30d accelerates from 0 to 100 km/h in 7.6 seconds and reaches a top speed of 222 km/h. In spite of having a 7 kW higher output than its predecessor, the vehicle’s average fuel consumption in the EU test cycle is now 7.4 litres/100 km, a reduction of 10%. The new  BMW X5 xDrive30d achieves a CO2 emission level of 195 grams/km.

Standard feature: Eight-speed automatic transmission with optimised shifting dynamics and unmatched efficiency.
All new BMW X5 model variants are equipped as standard with an eight-speed automatic transmission. The new transmission combines shifting comfort, sporting characteristics and efficiency at an unprecedented level. It contributes even more significantly towards a reduction in fuel consumption and emissions than the six-speed automatic transmission featured in previous BMW X5 vehicles. The new eight-speed automatic transmission is characterised by minimum converter slip and an innovative gear set configuration that permits additional drive positions and a greater transmission ratio spread without having negative effects on size, weight and the system’s intrinsic efficiency.

Intelligent BMW xDrive four-wheel drive technology: Fast response and precision for enhanced driving dynamics and optimised traction.
Permanent four-wheel drive with electronically-controlled variable torque distribution between front and rear axles not only gives the new BMW X5 supreme traction on off-road terrain, but also superior driving dynamics on tarmac. BMW xDrive technology was initially featured in the first-generation BMW X5 and has since then been constantly refined. It is an intelligent four-wheel drive system that uses a transfer box with an electronically controlled multi-disc clutch to constantly feed power as required to the axle that has the best contact with the road surface. As a result, xDrive also enhances driving stability when taking bends at higher speeds as it anticipates any tendency  to oversteer or understeer and counteracts these forces effectively.
In normal driving situations, BMW xDrive distributes drive forces to the front and rear axles in a 40:60 split. Sensors constantly measure slip on all wheels.
Within a fraction of a second, the system is able to vary the power distribution ratio. As opposed to previous four-wheel drive systems, BMW xDrive also reacts anticipatorily and does not wait until a wheel begins to spin.
Therefore, the vehicle is stabilised before the driver even notices the need to take action. Thanks to a new, more neutrally interpreted basic configuration, BMW xDrive featured in the new BMW X5 contributes even more significantly towards an increase in driving dynamics. Even during stable cornering, drive power is shifted to the rear axle, transferring up to 80 percent of power to the rear wheels. After cornering, the system returns to the normal setting to ensure optimum traction.

Precisely controlled coordination of xDrive and DSC.
Fast and precise adjustment of drive power distribution is guaranteed by the combined efforts of xDrive and DSC (Dynamic Stability Control) within the Integrated Chassis Management (ICM). This combination is also complemented by the optionally available, revised Active Steering system.
The stabilising effect of the variable distribution of power reduces the necessity for the DSC system to intervene. The selective braking of individual wheels and a reduction in engine output are not required until the threshold is reached. Additional DSC functions include the ABS antilock braking system, Automatic Stability Control ( ASC), a trailer stability control system, Hill Descent Control ( HDC), Automatic Differential Brake (ADB), Dynamic Brake Control ( DBC) and Cornering Brake Control ( CBC). Moreover, the system comprises brake drying in wet conditions, the hill-start assistant, fading compensation as well as the standard cruise control system with braking function featured. The special mode Dynamic Traction Control ( DTC) raises the tolerance of DSC, thereby facilitating an exceptionally sporting and active style of driving as well as the setting off in deep snow or loose sand with controlled drive wheel spin.
The BMW X5 is also equipped with a parking brake that uses both an electro-mechanical and a hydraulic function activated or released at the push of a button. The parking brake features an Auto Hold function that enhances comfort above all in stop-and-go traffic situations.

High-performance suspension technology and steering with standard Servotronic function. Optional Active Steering.
The suspension technology used on the new BMW X5 is the ideal prerequisite for supreme driving dynamics on tarmac. The suspension of the Sports Activity Vehicle features a double-wishbone front axle and a lightweight integral rear axle. The additionally available rear-axle air suspension, including automatic self-levelling, ensures a consistent ride height and unaltered driving characteristics at all times, regardless of load conditions.
The new BMW X5’s rack-and-pinion steering comes as standard with the Servotronic function for speed-dependent power steering. Furthermore, an active steering function is available which additionally varies steering transmission according to speed. Therefore, less steering wheel movement and effort are required when parking, whilst at high speeds a more indirect behaviour is achieved and the effect of power steering reduced in order to enhance directional stability and ride comfort.

Optimum supremacy with Adaptive Drive.
A combination of active body-roll stabilisation and variable damping control incorporated into the Adaptive Drive system is the guarantee of unparalleled supremacy within the BMW X5 competitive environment. With the aid of sensors, Adaptive Drive permanently monitors and calculates data on the road speed, steering angle, lateral and longitudinal acceleration, body and wheel velocity as well as height levels. This information is used to control the swivel motors on the anti-roll bars and the electro-magnetic shock-absorber valves. In this way body roll is reduced and damping is constantly regulated according to the current driving situation. The FlexRay high-speed data transmission system is used for fast and reliable coordination.

High-performance brake system and tyres with emergency running properties.
The BMW X5’s high performance brake system guarantees outstanding stopping power. Newly conceived lightweight brakes with 385 mm discs at the front and an aluminium floating caliper construction on the front and rear axles of the top-of-the-range BMW X5 xDrive50i ensure extreme stability  and maximum braking comfort.
Standard features on the new BMW X5 also include 19-inch light-alloy wheels on the BMW X5 xDrive50i and 18-inch light alloys on all other variants respectively. The range of optionally available light-alloys for the new BMW X5 is complemented by three variants with a Y-spoke design and wheels in the sizes 19 and 20 inch respectively. Runflat safety tyres, also supplied as standard, allow the driver to continue his or her journey and reach a garage even in the event of a total loss of tyre pressure. Depending on the load condition, it is possible to continue driving for a distance of between 50 and 250 kilometres. Furthermore, the tyre defect indicator permanently monitors the tyre pressure.

Highly rigid body structure, comprehensive occupant protection.
Like all BMW X models, the new BMW X5 has an extremely rigid body that – despite of its high degree of torsional stiffness – has an optimum weight thanks to intelligent lightweight construction. For the benefit of passive safety, the forces acting on the vehicle during an accident are passed on via the engine supports and chassis along various load paths, keeping them away from the stable passenger cell.
In addition to front and hip/thorax airbags, the interior of the new BMW X5 comes as standard with side curtain head airbags. It also features three-point automatic seat belts for all seats, belt force limiters, belt tensioners and crash-active headrests at the front as well as the ISOFIX child seat system for the second-row seats. All occupant restraint systems are centrally and electronically controlled. In the event of an imminent roll-over, roll-over sensors ensure that the curtain airbags and the belt tensioners are activated.

Unique in the competitive environment: New BMW ConnectedDrive driver assistance systems.
As part of BMW ConnectedDrive, the new BMW X5 offers a multitude of unique driver assistance systems and services for optimising comfort and safety as well as for the use of infotainment functions. Active Cruise Control with Stop & Go function is available as an alternative to the standard cruise control system with braking function. It additionally comprises Automatic Distance Control which allows for relaxed cruising in motorway or overland traffic, also ensuring that the selected distance from the vehicle ahead is maintained in low-speed stop-and-go traffic. If the selected distance from the vehicle ahead is insufficiently maintained, the system automatically makes  the necessary adjustments by intervening into the car control system and by building up brake pressure. If required, the vehicle can be brought safely to a complete standstill. After a short stop, the system automatically sets the car in motion again. If the vehicle stops longer than desired, the driver can restart the car by pressing either a button or by actuating the accelerator pedal.
The Lane Departure Warning feature also available for the BMW X5 is able to identify unintentional drifting from the lane at a speed of at least 70 km/h.
The system consists of a camera, which is installed on the windscreen in the vicinity of the rear-view mirror, a control unit for data synchronisation and a pulse emitter that activates a gentle but unmistakeable vibration on the steering wheel. The camera detects the markings on at least one lane. A control unit calculates the position of the vehicle in relation to these markings.
The system also works in bends, on narrow lanes and in the dark as soon as the headlights are switched on.
Furthermore, the Speed Limit Info function can also be used in conjunction with the Lane Departure Warning and the navigation system Professional.
This function offers the driver the possibility to obtain information regarding the route he is currently on. The camera used for the Lane Departure Warning permanently monitors road signs as well as variable overhead gantry signs on motorways.
A further technical innovation within the BMW ConnectedDrive range is the Side View system. It comprises two cameras that are integrated into the front wings, permitting observation of cross traffic. The images are transferred to the control display, making it possible at an early stage to identify traffic coming from the left or right, particularly when driving through a narrow gate or leaving a multi-storey car park.
Also available for the BMW X5 are the Head-Up Display, with which driver-relevant information is projected onto the windscreen within the driver’s field of vision, the High-Beam Assistant and Adaptive Headlights, including cornering lights, variable light distribution and adaptive auto-levelling. Further equipment options are Park Distance Control and a reversing camera, including the Surround View system. In addition, with BMW Assist,  BMW Online, BMW TeleServices and innovative remote functions, BMW ConnectedDrive also offers the world’s most unique choice of mobility services relating to traffic information, emergency calls, vehicle, information and office services, travel and leisure time planning as well as the Internet.
Optimised utilisation of telecommunication and entertainment systems is guaranteed, inter alia, by the full integration of external cell phones and  music players.
