BMW has re-engineered its X5 range for 2010, offering lower emissions and increased fuel economy.
Due to go on sale on June 5, the 2010 model year X5 range features revisions to both diesel engines offered.
The entry-level xDrive30d now produces 245bhp (up 10bhp on the previous engine) yet now returns claimed average fuel economy of 38mpg (up from 34mpg).
CO2 emissions have also reduced, falling from 217g/km to 195g/km. As a result, the X5 xDrive30d falls three benefit-in-kind tax bands. And despite a near-£2,000 price rise, company car tax bills are around £250 less per annum.
The current X5 xDrive35d is rebadged as the 40d and gains a 20bhp power increase to 306bhp. Fuel economy improves by 3mpg to 37mpg while CO2 emissions fall from 220g/km to 198g/km. Company car tax falls by around £400 per annum.
Both engines are now fitted with an eight-speed automatic gearbox, while some subtle revisions have been made to the look of the X5 with new bumpers and light units.
Inside, leather upholstery is standard across the range, as are Xenon headlights.
Elsewhere in the range, the petrol-powered xDrive48i is rebadged xDrive50i and comes with a 53bhp power rise, taking it to 408bhp.
Prices for the new X5 range start at £43,980.
