Description: Mercedes 508D 3.8 Di camper, Om314 engine. Short drive from cold on 19 November 2015 Springholm to Haugh of Urr . Vehicle is fitted with electric power steering. Level of electric assistance can be varied by dash mounted knob.PAS normally set lower for better feel and driven with both hands on wheel! Cruises nicely at a true 48-50mph as in this video and achieves about 22mpg on long trips fully warmed. Faster and it hits fuel consumption as does short runs like this but still high teens. Operated per Mercedes Drivers handbook with gentle right foot, early upwards changes and little braking it can be remarkably economical but I don't tend to go that gently unless road is quiet.
