I found on my test drives, if I accelerated reasonably gently up a slip road (even one on a slight incline) I could join 60mph traffic without the engine starting. Maintaining that speed started to drain the battery quite quickly of course. Driving with a light foot, it’s surprising how much 82hp can do. At town traffic speeds, performance on battery only isn’t going to get you racing around, but as Fadge says it was more than quick enough.
