That is great to know the range! It sounds promising to me I always wonder if I can go to San Jose and go home to San Bruno without charging… it maybe tight but I think it possibly can! Sent from my iPhone using Inside EVs
Absolutely -- piece of cake! You can use the 280 too, don't worry about avoiding highways. Especially considering the traffic there! You definitely need a Level 2 charger at home, though. The Level 1 won't cut it for that kind of use.
Pirelli Cinturato P7 RFT summers 205/45R17 and black tentacle spokes in mixed city + freeway was about 5.2mi/kWh (mid mode).
Update with city driving (same wheels/tires above) for 5.99mi/kWh in mid mode driving (air conditioning off). Regen was set to high and one pedal driving was used. Winter driving was in the 2mi/kWh range.
I recently got some new summer tires, Hankook Ventus S1 evo3 K127B in 225/45R17 94Y XL fitment (Fuel B / Wet A / Noise 70dB), for my 17"x7.5" NM Engineering RSe05 wheels. My review/opinions on them so far can be found here. Meanwhile, here's my updated highway range test table with them added: Method I used the same range testing route as prior tests, which is 62 miles long per Google Maps and verified by a GPS app. Of those 62 miles: 6.4 miles are on city streets and on/off ramps. 3 miles are at 65mph. 52.6 miles are at 70mph. (The speed limit is actually 75mph for 32 miles, but I maintained 70mph as that's the speed limit on any road trip route I'm likely to take.) For all highway driving, I used the cruise control set to the speed limit according to GPS speed, rather than the car's speedometer. Likewise, average speed was per GPS. This eliminates speedometer error (due to manufacturer offset and/or different overall tire diameter). Battery State of Charge was sniffed off the OBDII port via a Veepeak OBDCheck BLE bluetooth adapter and the "mi3" iOS mobile app. The wheel weights shown in the chart are per documentation on the internet. Wheel + tire weight was measured with my own digital scale. Tires were set to factory-recommended pressures: 17" = 38psi front, 35psi rear. 16" = 35psi front, 32psi rear. Granted, those pressures are for the stock size tires; I may explore different pressures for the larger 225/45R17 tires.
It's not as scientific as some of the other range testing but I did a 94mi drive today on some fun mountain roads and ended up using 67% for a projected range of 140mi! The result may not be as high as some others but it was on aftermarket wider wheels and UHP tires that have been averaging 1 mi/kWh worse than the OEM Hankooks and I wasn't exactly trying for efficiency (dashcams always look slow...): Really goes to show that as long as you start and end at the same elevation, hills (mountains) have almost no effect on range At 5300ft: Edit (forgot the details): Start: 100%, End: 33% Distance: 93mi from trip meter (93.8 mi from google) Average Speed: 37.9 mph Reported trip efficiency: 4.6 mi/kWh Calculated efficiency: 4.8 ± .06 mi/kWh (max/min rounding error of % and distance)
Nice! Looks like a lot of fun. How fast were you taking all the 15/20 mph curves? Wished I lived in the mountains....
I’m on Hankooks from factory 16” I remove a back seats and mats and all unnecessary staff and lost 30 lbs of my weight since January and I bet my range is better than all yours playing with wheels /tires unnecessary for great basic transportation as race car call Mini Cooper SE . Love a go cart .
I wasn't looking at the speedometer but not that fast, probably a bit less than double the suggested speed depending on visibility. There were a lot of cyclists so I was taking the blind corners pretty slow and only accelerating when there were good sight lines. The SE really does great in the tight corners!
