We took a nice fall drive with my M3 SR+ that I bought last year. I started with 100% charge, with a range of 227 (max when new was 231, not 240mi.) It was cool out so I set the interior manual temperature to 65 deg with A/C off. I have Sentry mode on when away from home and parked for about 5 hours straight for a hike and maybe 1/2 additional. I took a local road for part of the trip home and got 190 watt/mi (since last charge) for the 165mi trip with 28% capacity at the end of the trip. I assume the Sentry uses 2 mi/hour. If the SR+ has about 60+ kWh, My rough calculation (and ABRP App) says that the battery capacity should be roughly 42-45%. I’ve done other local touring drive and got 165 watt/mi (in cool weather) with almost no highway. My highway drives reports 240-265 watts/mi. again not in extreme weather. That range is disappointing but matches the recently reported 85% efficiency, less than usable 190 mi est. range if I don’t run to 0% . It seems like 190 watts/mi gives me slightly more than 100% efficiency. I thought the 240mi range was based on 240 watts/mi. If I am getting 190, I expect closer to 300 mi range. What is wrong with my calculations?
I bought this M3 with the wrong impression that the range Tesla reports is accurate on normal conditions now I wished I got the longer range battery.
The EPA range should have local and highway ranges to help us decide when buying the car like ICE.
