In a spirit of pure scientific inquiry -- no hedonic pleasure, us -- we took our M3 up into the local mountains yesterday. Our route:
Sherman Oaks (San Fernando Valley) up to Mt. Waterman (San Gabriel Mountains) and back.
53 miles each way.
Elevation 900 feet --> 7000 and back.
Mix of freeway and mountain highway.
Eager to see whether Tesla handled 335 --> 310 down-rate by:
Hiding capacity at top.
Hiding capacity at bottom.
Making RMs more realistic in between.
Preliminary evidence suggests they've gone primarily with door #3.
Trip up used 94 RMs (versus 110-ish) in our S85D.
Trip down used 9 RMs (versus 10-15) in our S85D.
Round trip used 103 RMs to go 106 actual miles.
This was at energy usage of 226 Wh/mi. Suggests "break-even" (to get rated range) just under 235.
Remote S charging data suggested just over 235.
Also noteworthy: M3's efficiency. As the photos below show, we gained 2 kWh, an average of 40 Wh/mi, on the 38-mile descent from Waterman to 134 Freeway ... more than we ever had in our MS. And, we didn't hit our net-zero point until just before the 134/101 transition, 45 miles ... better than we had ever done in our MS.
