Here's a very interesting
review by Henry in the UK, who's been driving an Oxford SE for 3 years. He doesn't feel the J01 SE is quicker than the Oxford SE. Also, he doesn't feel the J01's traction control is as good as the Oxford SE's traction control: "it scrabbles for grip."
Henry is clearly not blown away by the J01 (Quick! Watch it before MINI makes him take it down!):
"I think with the extra power, it kinda makes up for the extra weight. This is a heavier car than the F56 and [long pause] I wouldn't say this is a better car to drive. I feel that when I get back in my MINI electric F56 after this, I'm not going to miss the way that this drives. I'm not going to say this drives badly, but if you've ordered one of these, or looking to order one of these, and you're expecting a leap forward in the way it drives, in the last hour and a half I've had with this car, I wouldn't say it's blown me away, or we went 'Wow'.
"I've not fallen in love with it the way I did 3 years ago when I test drove the original MINI Electric, when I was like 'Wow!' That being said, if you haven't driven a MINI like it before, and you're coming into this from, say, an E28 or something more mundane, then you will like the way this drives and I would say this is a nice car to drive, but if you were expecting a leap forward over the current MINI electric, it's not this. It's not."
Henry discusses how the center display can show the turn signals flashing on the outside of an image of the car, but no report on if it can show you when the regen activates the brake lights (in my SE, I added an LED that's visible in the rear-view mirror so I can tell when regen is signaling to other cars I'm braking).
