I had a BMW 320d Estate 2015 model, easily achieved 60mpg sat at motorway speeds, replaced with a 630d GT which only managed 42mpg, wish I’d kept the 320 lolWhy are you not on an EV tariff like Octopus Go?
Costs me around 2p per mile for the electricity. I came from an incredibly efficient Diesel Passat and at best I was getting 55mpg by really cruising on motorways, what Diesel were you getting 60mpg with?
