I drove 370ish miles today, from Melton Mowbray to Newcastle upon Tyne, to Whitley Bay, back to Newcastle, then home, visiting son, having lunch, wandering through the Whitley Bay Carnival.
Grenadier was great, BBC Hercule Poirot on the In Car Entertainment, (ICE), but the fuel consumption was nothing great 21.7mpg. Used the cruise control for most of the journey, so either 70mph, (sat nav checked) or 50mph, in the roadworks. Very comfy for a long, (in UK terms), journey.
Son impressed with the Grenadier and now looking forwards to going to France in November - he can charge his phone in the back!
