But why?
Does anyone who can afford to lay out £90K for a car (probably north of £100K with extras) really give a damn whether it does 40MPG or 20MPG? Apart from giving you the chance to flaunt your green credentials at the country club this seems a largely pointless exercise.
As for you can unclip the charger from the wall and take it with you.. Why not just build it into the car then, and fit a power cord reel like on a vacuum cleaner? It could have a nice Porsche-styled 13A plug on the end. No need to unclip and carry anything.
Biting the hand that feeds IT
