Building on the success of the new X5, BMW has created a plug-in hybrid version.
Using a 2.0 litre four cylinder petrol engine combined with an electric unit, the X5 xDrive40e sees technology used in its show-stealing i3 and i8 models feed down into more conventional machines.
The electric motor will cover around 19 miles on zero-emission electric mode and will take around three hours for a full charge.
As with many plug-in hybrids, the system lets you use electric only, petrol only (while charging the batteries) or a combination of both. To maximise fuel and battery efficiency, BMW uses a sophisticated navigation system to automatically select the most suitable driving mode depending on conditions and terrain.
Elsewhere, the X5 is spacious, well equipped and engaging to drive for such a large car. With the usual highly-capable chassis, excellent eight-speed automatic gearbox and ergonomic cabin, the hybrid version of the X5 will begin to make you reconsider the diesel version you had your eye on.
