BMW i3 60Ah REx motorway range

[Synchromesh]

Could any i3 60Ah REx owners let me know the the battery driving range they get at a constant 65mph and 80mph, in both typical and 'worst case' scenarios?

Does this range reduce as the battery degrades with the age and mileage of the car?

Thanks in advance.

This is from "The Knowledge" in the i3 owners Facebook group. More detail is available, but essentially for your scenarios it's:

At 65mph:
22C: 70 miles
0C: 60 miles

At 80mph:
22C: 50 miles
0C: 45 miles

Perfect, just what I was looking for.

Do you know if, as an example, a 4 year old / 50k mile car would be achieving the same figures?

I understand battery degradation is negligible, probably because the cars are all still relatively new. Suffice to say there's not a consistent noise anywhere about people being disappointed about losing range with the car's age.

Of course that might change in the near future, but it's not considered to be a concern at the moment.

I wouldn't call battery degredation negligable. I certainly noticed it over the 4 years I had mine. It might only be 3 or 4 miles over that time but when you're only getting 45 miles in winter that's a noticeable percentage.

Tom Moloughney wrote a couple of good blog posts on the i3 battery degredation including data - worth a google if you want to learn more.

You'll get about 65 miles on the motorway ON AVERAGE before the REX cuts in at 6.5% from a 60Ah.
Less if its cold or you go too fast.
