Renault Trucks has given its Kerax tipper a power boost, by giving buyers the option of its DXi 13-litre engine. The new truck, which received its world premier at the Samoter construction show in Verona, Italy, last week, is offered in 460hp (2,300Nm) or 500hp (2,450Nm) guise. Although both are available for order in right-hand drive, neither vehicle will make an appearance on Renault's CV Show stand.
