After 15 miles ( & at all times)the electric motor is still charged by the ICE/regeneration on braking & coasting so will function and/ or help at higher speeds;when I renewed my tax this year on a 3/16 registered car it was still nil .The 15 miles is the electric only range which varies on driving ...

I think that most non PHEV hybrids have an electric range of about 1 mile;most of my trips are under 15 miles,often with charging at both ends, so it makes perfect sense for my type of use;it is less useful on longer journeys as the ICE is dragging batteries around,although the electric motor does ...

The pros are are great fuel efficiency & performance & in my case no VED (being registered in 3/16).I think that I read somewhere that the cost of a full charge from the mains is about £1 but I may be wrong on that. I obtain about 15 miles on electric,although it seems the decrease with colder ...

I don't know about a 50d but I moved to a 40e from an E61 M5 & have found the performance fine;the electric motor is great for moving off & it helps the ICE at high speeds.

With the "bad press" that diesels are receiving I can't see it depreciating faster than them in the medium to long term.

I achieve about 70mpg on short journeys with my 40e plugged in at both ends;longer trips are late 30s.

I've had my 40e for exactly a year & the mpg is unbelievable.I've visited the petrol station twice this year,in contrast to my previous car, a E61 M5.It is best for frequent short trips with charging ideally at both ends although even on long journeys the battery helps with economy.I would recommend ...

I've owned mine since new in April 2016 & often leave it fully charged & unused for a few days.Its always retained a full charge so there seems to be something amiss with yours. I hope that it gets sorted out.
