the maoster:
^^^ I had a 500 on demo for a couple of weeks. I don’t know if they’d played with it to make it more impressive but it would leave our 500 MAN’s standing on the hills at the same weight, and the MAN’s ain’t slouches. The Scanny also returned around 2mpg better too. Obviously because bean counters were involved we got the cheaper vehicle in the MAN.
When I was talking to the dealer when I took ours back, he said that their demo models usually run the vanilla map so that companies can see how they perform ‘out of the box’ but with the caveat that they can be spec’d for better performance or fuel economy as required. It could be that your demo was a vanilla map hence why it outperformed your MAN. Likely to be a different story if the company actually bought one and spec’d it for fuel economy like most logistics places do.
