Maybe I can help ..........I have had my Mini PHEV for about 12 months now .........I am retired and a volunteer on the canals in England so my journeys are short , less than 10-20 miles I typically get 16-18 miles from battery alone . This has depended on ambient temperature for charges etc , so in Winter 16 miles in Summer 20 miles on battery alone . But of course heater , seat warmers , lights a/c will impact on distances achieved .I'm writing from the U.S., where I find it is difficult to decode hype from fact (and, perhaps, where we are speaking to a particularly slippery showroom salesman). Our showroom salesman was telling us that while it's true there is an "all-electric range" on the 2020 Countryman S E that's quite low (some say 13 miles, some say 16), and there is an mpg rating of 27 mpg, this 27 mpg figure is based on "all gas" operation... and that in practice, most people will drive this car in a sort of "normal" mode that maximizes the engine's ability to operate as a hybrid. He claims he has customers who are going about 400-500 miles before they need to refuel. Since the gasoline engine is just under 10 gallons, that would translate to a 40-50 mpg rating.
Is this true? Those of you who own one of these hybrids: Please set me straight. What sort of mileage do you usually achieve?
Also on a longer journey (these are in Imperial units not US gallons etc) my tank+ batteries will take me about 240 miles , but after 230 miles I have 100 miles left in the tank/batteries ..........this is because of the regeneration . So far I use need about 9 miles per Kw petrol consumption is 63 MPG (imperial) and regeneration (recuperation) is 12 miles per Kwatt.......this is real data from a user that wants to keep cost down and as green as I can be .........hope this helps .
