All these fuel consumption figures are on a " tight" engine, and nothing meaningful can be achieved till the odometer is the other side of 1000 miles.I’m sure someone will have had a longer trip to report by the end of the weekend.. At 75mph, cruise control on, three up and full tank of diesel, the engine is doing c 2000rpm but my mix of driving yesterday delivered an average speed of 33mph for overall fuel consumption of 22mpg. A longer trip on faster A roads or motorway is what we want. I’d like to think that 25 to 30 mpg is possible..
