Innovative, with generous interior space but at the expense of the boot. I have an M60 — strong acceleration and excellent self-charging, especially on the motorway.

range that I can always charge to 100% — unlike other brands that told me it was recommended to stop at 80%, which consequently cut my real range from 600 to 480 by not being able to charge to 100%. I think that's something people should know.
