The trial data BMW has collected over the past 18 months is telling it that the perception many of us have that we need a vehicle with an extended range just isn't borne out by the facts.

The MGV, for example, will weigh 30 tonnes, and Canada recently began a trial of rubber tracks on the Mobile Tactical Vehicle Light (MTVL), a 22-tonne APC.

This control network was used in underwater vehicle which was developed by us and completes the lake trial successfully.
