At 4,671 millimetres in length, it is just 14 millimetres longer than the X3, but at 1,624mm high it is also 36 millimetres lower to the ground and cuts a dynamic profile with its perfectly balanced proportions and distinctive sporting character.
Based on the same platform as the BMW X3, the BMW X4 displays a character of its own. The large air intakes positioned on the outer edges of the front end and the character lines in the front apron lend the X4 a more muscular and agile appearance. This lowers the car's visual centre of gravity, signalling its sharper dynamics. The effect is further enhanced by the fog lamps sited below the signature twin headlights.
The coupé-like roofline reaches its highest point over the front seats, reflecting the traditional driver focus of BMW cars, before dropping gently down towards the trailing edge of the boot lid. The standalone design of the BMW X4 is further reinforced by the fresh interpretation of the signature swage line running along the flanks of BMW models. For the first time this is split into two the first section rises smoothly from the front wheel arches to the rear door handles, while the second part accentuates the powerful sculpting of the rear wings.
The driver focused cabin uses premium materials including subtle electroplated accents, a high-gloss black-panel look and aluminium trim strips in the wood panelling to create a luxurious ambiance.
The driver and front passenger sit 20mm lower and the rear passengers 28mm lower than in a BMW X3, accentuating the classic coupé feeling. The BMW X4 has a load capacity of between 500 and1,400 litres which, thanks to the standard 40:20:40 split-folding rear seats, can be used in a wide variety of ways. Everyday usability is further enhanced by the standard-fit automatically opening tailgate.
The BMW X4 offers a level of standard equipment well above that found on the BMW X3. As standard it comes with an automatically opening tailgate, Variable Sport Steering, 18-inch light-alloy wheels, front and rear Park Distance Control, Performance Control and Xenon headlights. Inside the BMW X4 40:20:40 split-folding rear seats, a Sport leather steering wheel, Heated front seats and BMW Business Media package are all standard.
For an additional £1,500 the xLine trim level will also be available on the BMW X4. This includes an exclusive18-inch light-alloy wheel, Satin Aluminium exterior trim, Dark Copper interior trim, Sport seats and exclusive xLine leather upholstery.
The M Sport model costs an additional £3,000 over the SE and offers greater dynamics and visually boosts the X4's sporting appeal. The M Aerodynamic bodystyling, High-gloss Shadow Line trim exterior trim and an exclusive 19-inch M Sport light-alloy wheels lends the BMW X4 an more sporty appearance, while the M Sport suspension enhances the ride. BMW M door sill finishers, Sport seats and an Aluminium Hexagon interior trim add the finishing touches.
All X4 models have a sporty suspension set-up and come with BMW's intelligent xDrive all-wheel-drive system as standard. This ensures that the drive is split between the rear wheels continuously and as required, which further improves traction, turn-in and directional stability. Working in tandem with the standard Variable Sport Steering, these systems allow the X4 to deliver driving dynamics that surpass even those of the X3 in terms of sportiness. An xDrive status display uses three-dimensional graphics to keep the driver informed of the car's body roll and pitch.
From launch the new X4 will be available with a choice three diesel engines, all of which meet the EU6 standards. TwinPower Turbo technology ensures that performance is maintained while fuel consumption and CO2 emissions are kept to a minimum.
The BMW X4 xDrive20d is powered by a newly developed 2.0-litre diesel engine with an all-aluminium construction. This power unit develops 190 hp at 4,000 rpm with a peak torque of 400 Nm. As a result, the X4 xDrive20d requires 8.0 seconds to sprint from zero to 62 mph. The X4 xDrive20d comes as standard with a six-speed manual gearbox but can be optionally specified with an the eight-speed automatic transmission which brings fuel consumption down to 54.3 mpg and sets the CO2 emission at 138 g/km.
The 3.0-litre six-cylinder in-line engine in the xDrive30d, paired with the standard eight-speed Sport automatic transmission, returns a combined mpg of 47.9 while CO2 emissions are 156 g/km. These parsimonious emissions don't impact the performance with the engine outputting 258 hp at 4,000 rpm with a peak torque of 560 Nm from as low as 1,50 0rpm, while it accelerates from zero to 62 mph in 5.8 seconds.
The xDrive35d engine tops the BMW X4 line-up. The 3.0-litre diesel delivers 313 hp and puts a peak torque of 630 Nm on tap from between 1,500 and 2,500 rpm. With its standard-fitted Launch Control, the X4 xDrive35d launches from zero to 62mph in a mere 5.2 seconds and goes onto a top speed of 153mph. However, the X4 xDrive35d still posts fuel consumption of 47.1 mpg and emits 157 g/km CO2.
A suite of EfficientDynamics technologies also minimises the fuel consumption and emissions of the new X4. Features such as Auto Start- Stop, Brake Energy Regeneration and on-demand operation of ancillary units are standard across the range. Optionally available are 17-inch aero wheels with reduced-rolling-resistance tyres, which reduce the CO2 emissions of the xDrive20d and xDrive30d by a 7 g/km.
The Driving Assistant offers additional potential for fuel saving. This technology uses route data supplied by the car's navigation system to identify situations in advance which will require the car to slow down (e.g. on the way into towns and villages, speed limits etc.) and gives suitable recommendations.
The BMW ConnectedDrive features available for the new X4 offer class-leading technology in the link-up of driver, vehicle and the outside world.
Providing added safety and greater convenience in the X4 is the optional full-colour Head-up Display, which projects all important driving information and the assistance system displays into the driver's field of vision. The latest-generation Professional Multimedia Navigation system, with ECO PRO route guidance, now teams up with the iDrive Touch Controller. Safety and convenience can be further enhanced by option including the anti-dazzle High-beam Assistant, Driving Assistant Plus including Pedestrian and Collision Warning with City Braking function, Active Cruise Control with Stop and Go function and Lane Departure Warning.
The optional BMW ConnectedDrive services allow customers to access smartphone applications such as AUPEO! or Deezer as well as innovative mobility services via the built-in SIM card. Remote Services and Real Time Traffic Information (RTTI) can likewise be used from the comfort of the car.
Online Entertainment provides direct access to music services such as rara or Napster with their millions of music tracks as well as audiobooks. The intelligent e-Call function is triggered automatically or can be used manually to alert the authorities. As soon as the crash sensors report an airbag deployment, the system sends the vehicle location and all key information to the BMW Call Centre via the built-in SIM card, enabling fast and effective assistance at the accident location.
The BMW X4 arrives in dealerships on 12 July, 2014 and will be priced from £36,590 OTR for an X4 xDrive20d SE.
