I think I must be miscalculating, but based on the specs I have read online, the e Tron range will have a 11kwh charger, which takes aboit 12 hours, and a 22kwh charger which takes about 8 hours to charge. Going off the 11kwh charger and using an average of 14p per unit of electric, that's (11*0.14)*12=£18.48 for a full charge, for a maximum of a 250mile journey. That works out at 7.3p per mile. Comparing that with a normal car that can do 50mpg, and at a average fuel price of £1.18, that works out at 10.7p per mile. The batteries are going to deteriorate with age so will hold less charge and take longer to charge. So is there really enough in this to make e Tron worth it at the moment?
