One lead vehicle and four trailing vehicles - consisting of a Volvo S60, a Volvo V60 and a VolvoXC60 plus a truck - made up the historic road train in Spain.
For the first time ever a road train comprising a VolvoXC60, a Volvo V60 and a Volvo S60 plus one truck automatically driving in convoy behind a lead vehicle has operated on a public motorway among other road users.
