Range and efficiency varies by car maker, some are much more efficient than others. Stellantis still doesn’t seem to be particularly good, Renault has great range from the Scenic, but if you look at the range test figures it’s not as economical nor as close to its claimed range as the Koreans or, of course, Tesla (not on the scheme, so a moot point perhaps).
The battery in the i4 35 is not massive at 67kw useable vs the Fords 88kw useable (98.7kw total). It’s like driving a 70ltr fuel tank petrol vs a 50. Power tends to be limited by both the size and type of electric motor along with the maximum Kw draw set by the manufacturer, so at 50% battery, they both may allow 75% max power, 30% might be 45% power and downwards to the dreaded yellow tortoise and sod all power. The Ford of course, reaches that 50% much later so its power is more available more of the time.
The various full to empty range tests give interesting real vs claimed range %, this, to me, along with a decent charging curve to avoid long refill stops is what counts, once you specify a battery of 64kw or above.
Winter weather can really hit hard. I had to go from home to Aberdeen, then Dundee, then home at 10pm last Sunday, -2 most of the trip, strongish winds, some rain, car was at 76%, I got home with 2% remaining, the car stating 176 miles on setting out. I did 153 miles in total, almost all at 70+ mph. Thank you to Scotrail for cancelling the train my wife and son were counting on to get home from their night out…and yes, I am looking forward to my next car, it has 80kw useable vs my current 64kw.
In life, it's not who you know that's important, it's how your wife found out.
