BMW has revealed xDrive40d variants of the X5 and X6 that feature a new diesel engine with mild hybrid technology.

 

The engine in question is a 3.0-litre straight six-cylinder diesel engine with a 48-volt starter generator. Total outputs are listed at 250kW and 700Nm, the latter is available between 1750 and 2250rpm.

 

The 48-volt starter generator of the mild hybrid system can output an additional 8kW when prompt acceleration is required. The system can also recuperate energy when braking and switch off the diesel engine when coasting.

 

An eight-speed automatic transmission sends power to a rear-biased all-wheel drive system.

 

Both models can sprint from 0-100km/h in 5.5 seconds while, depending on the final spec, consumption on the combined cycle is listed at 5.9-6.4L/100km for the X5 xDrive40d and 5.8-6.2L/100km for the X6 xDrive40d.

 

At this stage, it’s unlikely the X5 and X6 xDrive40d will be available locally.
