Maybe this is a stupid question, but can the SR+ make use of full 150kw supercharge speeds? I know there are factors involved in supercharging meaning you often won't get the top speeds, but I'm yet to get more than about 50kw after trying 3 different superchargers and a 150kw Polar. Below is what I have tried: Supercharger at West Drayton Put it on the supercharger at West Drayton during pickup. There were a few other M3s in other bays which I guess cut the speeds down. I got up to 53kw for this charge. Supercharger near Excel I used a dual-bay supercharger near excel. Got about 25kw. The other adjacent bay was in use, and I know that bay 1B has been reported as faulty in the past. Supercharger near Tower Bridge Again another two bay. The other bay was plugged into a Model X but wasn't charging (no green light). I got about 43kw max. Polar 150kw rapid I tried the new Polar 150kw chargers by Hammersmith Flyover. There are 4 chargers there. When I plugged in, the other 3 bays were in use by eTaxis. I got 44kw max. Anyone know if those Polar 150kw ones have the same issue as the Tesla ones where your speed is cut if other people are using other bays at the same site? Do these speeds seem normal in the above circumstances? If I tried a semi-empty motorway supercharger bay do we think i'd get the full 150kw?
