I picked up my first MS 75 in June 2017. For reasons I won't get into, that was replaced by a new, exactly identical spec, MS 75 which I picked up yesterday. The new vehicle is noticeably faster accelerating. Any ideas why that could be? I heard rumors of an 85 kWh pack; is there a way I can check whether there is one in there? Or just variability in the electric motor efficiency? I don't think I'm imagining this since I drove both cars within an hour or two of each other..
