Hmmm, 10 miles does not seem right, by any stretch of the imagination. Here’s my experience in regards to the electric drive on the PHEV. Ever since taking delivery of my 2021 330e xDrive (I upgraded from a 2019 330i xDrive), I’ve adjusted my driving style to be a lot less of a hooligan. When in EV mode, I always try to keep the power gauge on the right as close to “0” as possible. Even hitting “20” causes the battery to drain much quicker. Try to plan ahead early for stops so you can get the most from regenerative braking. Also, light pressure on the brake pedal induces more regen before resorting to the power of the actual brakes themselves. With climate control off, I can hit around 28 to even 31 miles on a full charge—24 to 25 with climate on. Make use of iDrive navigation even if you know where you’re going, as it will help the propulsion management system determine the most efficient mix between power modes. Hopefully, these tips can push up your mileage a bit, but if you’re still getting such low mileage… then a trip to the dealer might be in order.
