Finally did my first range test.
Conditions:
50-60°F, I did not need the heater or AC. I had preheated the car and charged it to 100% or 352 mi indicated.
It is 4 miles to the freeway. I drove until ~56% SOC, then turned around without stopping and took the same route to eliminate wind factor. Wind was very light.
Used the Interstate 15 from Corona to almost Baker, California. Terrain involves a climb of about 3600 feet, but it occurs both ways.
Used TACC and Autosteering. Normal driving mode. 45 psi cold, 20" wheels. ~270lb of total cargo. Hitch was mounted, nothing on it.
Car/tires had ~250 miles on it.
Freeway driving was set at 75 mph, but had to slow to 70 mph at times, and had to pass at 85 mph a couple times. Pretty much like I drive in a 70 mph zone when I am not in hurry.
SOC start 100%, SOC end 14%, consumed 78.3kWh. Miles driven (odometer) 229.3mi 3h14m 342Wh/mi = 266.6 miles drop dead range @ 75 mph. Battery holds 91 kWh.
Review - The Range estimator is basically a voltmeter with a table corrected to 100% = 354 miles maximum charge state. At 50% SOC it reads 177 miles, etc. Never trust it. It does not learn at all from what I can tell. ie - 20 miles indicated is not based on current driving efficiency.
Some people are going to be disappointed with the EPA range claim. You will have to drive slower than 75 mph to get over 300 miles out of the car out west. It does have more range than any SUV style EV, but do not plan based on 351 miles. It does not have 100 mile of extra freeway range over it's competition.
Is it really more range than the early Raven Long Range model? That I cannot tell you.
Sidebar - IMO the seat is a "Good 2h" seat. Not a "Great 4h" seat.
Spotify locked up after I left the urban area, but still with 5 bars of LTE. Bug or bandwidth? I don't know.
Since AM isn't available, always keep a Music USB handy when travelling cross country.
