Driving Experience: Agility Simply Fascinating Wherever You Go.

• xDrive making its debut in the compact segment.
• Variable distribution of drive power for even greater agility in bends.
• Entry-level models with rear-wheel drive typical of BMW.
“The BMW X1 proves convincingly how much driving pleasure a car in the compact segment is able to offer.” Heinz Krusche, Head of Driving Dynamics Assessment For the first time, the BMW X1 carries over the Sheer Driving Pleasure so characteristic of BMW’s X models into the compact segment. The unique driving experience provided in this way results from the combination of powerful engines and the most advanced suspension technology which, apart from the elaborate front and rear axle configuration, also comprises the precise steering free of any effects from the drivetrain as well high-performance brakes.
Well-balanced axle load distribution likewise contributes to the agile handling of the BMW X1 characterised above all by fascinating sporting qualities in the style so typical of a BMW X model above all due to the elevated seating position.
Superior transmission of drive power to the road is ensured at all times, also off the beaten track, by BMW’s intelligent xDrive all-wheel-drive system. This permanent, electronically controlled all-wheel drive promotes both the driving dynamics of the BMW X1 as well as the car’s driving stability and traction.
On the two particularly economical entry-level BMW X1 sDrive20d and BMW X1 sDrive18d drive power is fed exclusively to the rear wheels, enabling the customer to enjoy the transmission of drive power so typical of BMW also in the compact segment.
Regardless of the type of power transmission, all variants of the BMW X1 come with DSC Dynamic Stability Control including DTC Dynamic Traction Control.

Supreme agility ensured by advanced suspension technology and a stable body structure.
The driving behaviour of the BMW X1 combining superior agility, precision and supremacy at all times results directly from the high level of suspension technology as well as the particularly sturdy body structure. Upfront the all-wheel-drive models come with a double-joint thrust bar axle, the BMW X1 sDrive20d and the BMW X1 sDrive18d featuring an aluminium double-joint tiebar axle. In conjunction with the five-arm rear axle featured on all models, this ensures optimum harmony of sportiness and driving comfort.
The hydraulic rack-and-pinion steering comes with precise dosage of power assistance, Servotronic power steering operating as a function of road speed and featured as an option on all all-wheel-drive models for even more effortless handling.
The powerful brakes on the BMW X1 ensure excellent stopping power under all circumstances. Depending on the engine variant, the brake discs on all four wheels come in various sizes and, again depending on the model, as swing calliper or frame calliper brakes at the front.
All model variants of the BMW X1 feature 17-inch steel or, respectively, aluminium wheels as standard. Another standard feature is the Tyre Pressure Indicator, while runflat tyres enabling the driver to continue to a workshop nearby even after a complete loss of pressure are available as an option.

Intelligent all-wheel drive featured for the first time in the compact segment.
Variable distribution of drive power between the front and rear wheels through BMW xDrive all-wheel-drive technology enhances the agility of the BMW X1 and ensures superior traction on rough surfaces. Thanks to the convincing qualities of this cutting-edge technology, BMW is now the world’s most successful supplier of all-wheel-drive vehicles in the premium segment.
The BMW X1 is the first vehicle in the compact class to offer such intelligent all-wheel drive, with xDrive feeding drive power appropriately and properly dosed in each situation through a power divider incorporating an electronically controlled multiple-plate clutch to the axle with optimum wheel contact on the road.
All-wheel drive is networked with DSC Dynamic Stability control and engine management also on the BMW X1, with sensors on the wheels immediately determining even the slightest slip, the system then varying the distribution of drive power within fractions of a second. This is done before a wheel even starts to spin, thus counteracting even the slightest trend to over- or understeer in good time and with maximum effect.
In bends more drive power is conveyed to the rear axle even when the vehicle is stable in the interest of extra agility and again to avoid understeer. In the interest of optimum drive force, the standard 40:60 front-to-rear set-up is reinstated right away at the end of the bend, enabling the driver to accelerate smoothly and safely on to the next straight.
The distribution of drive power via xDrive ensures optimum driving stability even in the most demanding situations, with DSC cutting in to re-establish driving stability by applying the brakes individually on the appropriate wheels and reducing engine power only when a change in power division is no longer sufficient.
DSC Dynamic Stability Control also comprises ABS anti-lock brakes, DBC Dynamic Brake Control, CBC Cornering Brake Control and DTC Dynamic Traction Control on the BMW X1. DTC Dynamic Traction Control raises the driving stability control thresholds, allowing the driver to set off more smoothly in deep snow or on sand with the wheels slightly spinning. On the BMW X1 xDrive28i the DSC function is further enhanced by features such as Dry Braking in the wet, Fading Compensation and a Start-Off Assistant.
Through the networked xDrive control electronics, Performance Control available as an option also in conjunction with the optional sports suspension set-up ensures carefully dosed application of the brakes on the all-wheel-drive versions of the BMW X1 and also provides appropriate torque compensation to effectively counteract even the slightest tendency to understeer right from the start and ensure greater agility on slippery surfaces and in particularly dynamic bends. As soon as the front wheels start to push to the outside, therefore, the inner rear wheel is slowed down appropriately by integrated xDrive and DSC electronic control, the loss in drive power suffered in this way being compensated by an increase in the power delivered from the engine.


BMW X1 sDrive20d and BMW X1 sDrive 18d with rear-wheel drive in typical BMW style.
Both the 190 kW/258 hp straight-six power unit and the four-cylinder diesel with BMW TwinPower Turbo and 150 kW/204 hp come in a perfect combination with BMW xDrive. The two other diesel engines, in turn, are combined with rear-wheel drive, the BMW X1 sDrive20d and the BMW X1 sDrive18d providing the driving experience so characteristic of a BMW quite unique in the compact segment and so far offered only by the BMW 1 Series. At the same time these models excel through their particularly high standard of fuel economy and emission management.
Contrary to front-wheel drive so common in the compact segment and also among the competitors of the BMW X1, rear-wheel drive ensures particularly dynamic acceleration, prevents any spillover of engine power to the steering, and promotes well-balanced axle load distribution. A further point is that a vehicle driven by its rear wheels benefits from the inertia forces generated when accelerating. Dynamic axle load distribution takes the usual load off the front axle, avoiding the risk of the wheels spinning so common in the case of front-wheel drive, and ensures better transmission of power to the rear wheels. And last but not least, traction also benefits from a high load in the vehicle, with the additional weight resting on the drive axle and thus improving road and surface contact.
