2015 BMW X1 unveiled - new pictures, pricing

Underpinning the new BMW is a MacPherson strut front and multi-link rear suspension shared with the 2 Series Gran Tourer. It is allied to an electro-mechanical speed-sensitive Servotronic steering system that is engineered to provide lighter weighting at lower speeds for added manoeuvrability around town and a firmer feel at higher speeds for increased stability on the motorway.

The new compact off-roader rolls on 17in alloy wheels as standard, with 18in and 19in rims available as an option.

In a first for the X1, the new model comes with adjustable dampers in combination with an optional Driver Experience Control function that enables the driver to choose between Sport and Comfort suspension settings, along with Sport, Comfort and Eco Pro driving modes.

The new X1 will be launched in the UK with a turbocharged 2.0-litre four-cylinder petrol engine in two states of tune and a 2.0-litre four-cylinder turbodiesel in three outputs.

The petrol unit is from BMW’s new B48 engine family, delivering 189bhp and 206lb ft in the 20i for increases of 8bhp and 6lb ft over its predecessor. The xDrive25i is the fastest X1, with a 0-62mph time of 6.5sec and a 146mph top speed. It develops 228bhp and 258lb ft - 14bhp more than the outgoing xDrive28i.

The diesel engine is also a new development. Codenamed B47, it replaces the older N47 unit used by the previous X1. It delivers 148bhp and 243lb ft in the X1 sDrive18d, 187bhp and 295lb ft in the xDrive20d and a class-leading 228bhp and 332lb ft in the xDrive25d.

The entry-level X1 sDrive18d is the only model to receive a standard six-speed manual gearbox. All other new X1 models come with an eight-speed automatic gearbox, which, in combination with the optional Driver Experience Control, includes a coasting function that disengages the clutch when you lift off the throttle at speeds between 31 and 99mph, as standard.

The X1 sDrive18d and sDrive20i come as standard with front-wheel drive, while the others - the xDrive20i, xDrive25i, xDrive20d and xDrive25d - all get four-wheel drive as standard.

BMW claims the four-wheel drive system used by the new X1 is considerably lighter and boasts a 30% reduction in torque losses over the older arrangement for added fuel savings and greater traction in off-road conditions. Among the long list of standard driving aids on all models is DSC (dynamic stability control), DTC (dynamic traction contol) and CBC (cornering brake control).

The most economical model in the launch line-up is the front-wheel-drive X1 sDrive18d. It returns a claimed 68.9mpg combined and emits 114g/km of CO2. The performance leader is the X1 xDrive25i, which boasts an official 0-62mph time of 6.5sec and 146mph top speed.

Further engines will be added to the line-up later on, including the new B38 three-cylinder petrol unit in a front-wheel-drive successor to today’s rear-wheel-drive X1 sDrive18i. Already offered in the 2 Series Active Tourer, the turbocharged 1.5-litre triple delivers 134bhp and 162lb ft of torque.

Also planned is a front-wheel-drive follow-up to the existing rear-wheel-drive X1 sDrive16d running BMW’s new B37 three-pot diesel. The 1.5-litre engine is likely to offered in its highest state of tune, with 114bhp and 200lb ft.

Alongside standard models, BMW is also working on a performance variant of the new X1 as a rival to the likes of the Audi Q3 RS and Mercedes-Benz GLA45 AMG.

Details remain scarce, but automotive industry component supplier sources close to BMW’s M division confirm the company is engineering a high-output variant of its parent company’s new turbocharged 2.0-litre petrol engine. In standard guise, it kicks out a maximum of 231bhp, as fitted to the 225i Active Tourer. However, detailed revisions to the induction system, together with other power-enhancing tweaks, are said to take peak output to “well over 300bhp”.

It is still unclear whether this new engine will be offered in the X1 or remain the preserve of the more sporting X2. But in combination with standard four-wheel drive, it promises to provide the hot SUV with heady levels of performance. Nothing is official, but a 0-62mph time of under 5.0sec and a limited 155mph top speed are well on the cards for the hottest of Munich’s new pairing.

Also under development, but not likely to form part of the initial launch line-up, is a plug-in petrol-electric hybrid version of the new X1. It is claimed to use a similar powertrain set-up to that of BMW’s original Active Tourer concept, revealed at the 2012 Paris motor show.

The concept used a turbocharged 1.5-litre three-cylinder petrol engine to power the front wheels and an electric motor to drive the rear wheels, with a combined system output of 190bhp, combined fuel economy of more than 130mpg and an electric-only range of almost 19 miles.
