BMW X4 is all-new, but you probably can't tell


As the X4 is more like a sporty derivative of the function-oriented X3, the improvements mirror those of the donor vehicle.

United Kingdom buyers will only get a diesel option for now - a fearless move in the current climate - but a petrol could follow in the future. A further 30d six-cylinder diesel model will also be launched later in 2018, likewise a hot X4 M. Larger, lighter and more powerful, the new SUV is on sale now from £42,900.

BMW has only released pricing information for the entry-level X4 20d (£42,900) and M40d (£55,315), but more specs and prices will revealed in full when the X4 makes its global debut at the Geneva Motor Show on 8 - 18 March.

There's a wide array of available powertrains - three petrol and three diesel units, with power outputs between 135 kW/184 hp and 265 kW/360 hp (fuel consumption combined: 9.0 - 5.4 l/100 km [31.4 - 52.3 mpg imp]; Carbon dioxide emissions combined: 209 - 142 g/km).

True, the X4 has been on the market for only four years, and models usually last around 6-7 years in one generation before being renewed.

Digital services on offer through BMW ConnectedDrive include compatibility with Apple and Android smartphones, and Amazon Alexa personal assistants. A 10.25-inch touchscreen can be had along with a head-up display and three-zone climate control. An acoustic glass windscreen is standard and helps cut noise on the move, while the same material can be specified for the front side windows, too. The boot has a capacity of 525 litres and the load space can be expanded to a maximum of 1,430 litres by folding down the sections of the rear backrest, with its standard 40:20:40 split.

But the core-selling model for the X4 is expected to be the 20d armed with 190hp 2.0-litre diesel-turbo, eight-speed automatic and xDrive four-wheel drive.

At launch, BMW will offer a choice of powertrains, including the xDrive30i package making 248 horsepower and 258 pound-feet of torque. Average economy of up to 51.4mpg is claimed, along with Carbon dioxide emissions of between 163 and 168g/km, depending on exact specification.

On top of that, every version will have M Sport suspension as well as speed-sensitive steering, which allows for easy manoeuvrability at low speed and more feel at high speed. It accelerates to 62MPH in eight seconds and returns an average consumption of 52.3mpg and Carbon dioxide emissions of 142g/km.

The turbodiesel M40d won't be a slouch, either, covering the same acceleration run in 4.9 seconds - just 0.1 second slower than the petrol-powered version.

Diesels are likely to be the most popular X4 models in the United Kingdom and there's no shortage of choice.

A 2.0 liter turbocharged four cylinder engine is present beneath the bonnet. Fuel consumption ranges from 50.4 to 52.3mpg depending on spec, with Carbon dioxide emissions of up to 149g/km. Naturally, the six-cylinder x30d is the quicker of the diesels, with a 0-62mph time of 5.8 seconds, but the x20d (which can hit 62mph in 8.0 seconds) is more economical, with claimed economy of up to 52.3mpg and Carbon dioxide emissions as low as 142g/km. Average economy is as high as 51.4mpg, with Carbon dioxide emissions ranging between 145 and 149g/km. BMW quotes 0-100km/h in 4.8 seconds and an electronically limited top speed of 250km/h, while slurping 9.2 litres per 100km on the old NEDC rating. The former will return up to 47.9mpg on average, while the latter manages a maximum of 44.1mpg. The figure rises to £55,315 for the range-topping X4 M40d trim.

The 2019 BMW X4 will be released in July with a starting price of $50,450.

Drivers can choose between xLine, M Sport X and M Sport variants, but no matter which version you go for you'll get 18in alloy wheels as standard (although sizes of up to 21in are available). The navigation comes with a few extra goodies, including an on-street parking information system that will show colors indicating the probability of finding parking in select areas.

The interior is much the same as in the X3, meaning a combination of excellent build quality and the latest iDrive infotainment system wrapped up in a sophisticated and well-presented package. Driver assistance features and connectivity technologies have been improved.

BMW's decision to carve a sleeker shape from its X3 crossover once seemed curious but it's now commonplace.
