The second-generation BMW X3 has been unveiled with new technology and class-leading low-CO2 emissions.

The new model, which will arrive in the UK in November, offers CO2 emissions of 149g/km for the xDrive 20d, along with fuel consumption of 50.4mpg on the combined cycle.

A new eight-speed automatic transmission option on the 184bhp 2.0-litre engine delivers identical fuel consumption and lower CO2 emissions of 147g/km, and is the first vehicle on the market combining stop-start technology with a conventional torque converter automatic.

Any autos up to now offering stop start have either been CVTs or double-clutch electronic manual gearboxes.

The new X3 includes higher-grade materials than the outgoing model and offer BMW’s iDrive driver interface as standard.

Luggage volume ranges from 550 litres with the rear seats in place and up to 1,600 litres up to roof height with the rear seats folded.

The range will launch with the xDrive 20d, which will take about 80% of sales in the UK, while other engine variants will follow later.

This version has a 0-62mph sprint time of 8.5 seconds, a maximum speed of 130mph and maximum torque of 280lb-ft.

The new model comes with electric power steering to help reduce fuel consumption while BMW also promises class-leading agility, and will offer optional variable damping control and a head-up display.

Key options have been selected to form packs, based on the most common option groups of previous owners at reduced costs compared with choosing the options separately, while prices for the X3 xDrive20d will start at £30,490 on the road.
