BMW has released the first official pictures of its new X5 and revealed that it will be available with a four-cylinder diesel engine and two-wheel drive, reducing running costs compared with the current model.

The X5 will be on sale in the UK from November 16 and the 2.0-litre 218bhp rear-wheel drive model is expected later in the year, and will achieve 50.4mpg and emit 149g/km CO2 with prices starting at £42,590. The move to offer a four-cylinder diesel unit comes after Mercedes offered a similar engine in its M-Class last year.

All models will come with an eight-speed automatic transmission which has an Eco Pro mode that adapts the engine management, accelerator response and transmission characteristics to support a fuel-efficient driving style, and programmes the climate control and heated seats and mirrors for the most efficient use of energy.

Auto Start-Stop, Brake Energy Regeneration, on-demand use of auxiliary units, electric power steering and low rolling resistance tyres will also be standard on all models and new weight-saving measures mean the new X5 will be the lightest in its class.

Safety features include a lane assist system and an automatic braking system that detects a potential accident and initiates moderate braking at speeds of up to 35mph.

Alongside the 2.0-litre diesel unit the X5 will be available with a 3.0-litre six-cylinder engine that produces 258bhp and is 19% more fuel efficient than the previous model, as well as an xDrive40d, M50d and a petrol-powered xDrive50i.
