So, my buddy and I decided to race our two Teslas from a roll starting at 45 or 50mph. For most of the races, I was around 80-85% while he was at around 50-55%. I being in the faster vehicle thought I would crush him, but was amazed that he managed to stay in the race and took me quite a while to get away from him. At first, I thought he could possibly have the acceleration boost, but he doesn't. Is there a reason for this especially since his car could have performed better with a higher state of charge?
