I own a new 2019 P100D Raven that charges to 340 miles. I planned a 280 mile trip and returned with just 5 miles of charge left (1%)?!
1) When I left my house, I noticed I was charged only to 330 miles even though I maxed out battery charging capacity and turned of Sentry mode? (So I lost 10 miles of range before even leaving home).
2) I drove in 80 degree weather, partly in the rain, mostly on autopilot, at about 80 mph, but usually 70-75 with occasional stop and go traffic and 80% of the trip on the interstate highway.
3) Upon the return leg, my Tesla said I need to not drive above 70mph to make it home with enough charge. But after following that advice, it then told me I must drop down to 65mph. This was extremely frustrating as I had to be the slowest car in the right lane.
What went wrong here? Is 340 miles of range really mean 285 miles of range with real world driving conditions??
