And another real world trip. I used 30% battery to travel 37 miles, or 1.23 miles per 1%. This was a 50/50 city/highway mix with 45/75 posted signs. I drove about as aggressively as possible to get the worst result I could. Outside temp 85-90F. AC set to 60F. The car was driven much lighter over the previous few hundred miles. GOM readout versus real world: 100% charge: 84 miles / 123 miles 87%: (still) 84 miles / 107 miles 70%: 62 miles / 86 miles Mini, fix the GOM!
I celebrated Wattson's first birthday with a whole lotta driving fun. Cars & Coffee in the morning followed by the Kansas City MINI Club's Taco Run which included destinations in 3 surrounding towns. 202 miles total (mixed city/highway driving), with 2 fast charging stops (~25 minutes each), and arrived back home with 29% charge remaining. I averaged 4.7 mi/kWh for the day, which would be a range of 135.83 miles. The most efficient leg (26 miles) was 5.85 mi/kWh and the least efficient (2 miles) was 3.38 mi/kWh. For the trip home, the GOM dropped 20 miles (!!!) of estimated range from the value it showed when I arrived at that stop. The nav estimated I had *exactly* enough range to get home when I departed (64 miles) even though I had 73% SoC, a long-term efficiency of 3.9 mi/kWh, and 4.7 mi/kWh for the day. By the time I was 6 miles from home, the GOM showed I had 31 miles of range. That's just silly.
I believe they calibrated the MINI's GOM around the Nurburgring. That is the only place it seems to be accurate
For those of you who have driven your Mini is REAL WORLD cold weather (32F and lower), has anyone calculated actual range using battery % and distance travelled? I bet it has been posted here before, but I don't remember and am just curious.
I was getting about 90-100 miles IIRC. My average through Feb I think wnt up from the 3.2 mi kwh to 3.4 or so. Now through the summer my average is 4.2. With 4.5-5 being average it seems.
This is a great point. I would assume most of us are running the (stock) summer tires and never drive below 40-45F. Maybe there should be a cold weather range thread?
See the thread on cold weather observations, specifically when I was driving in temperatures of -20 ºF and lower. I was parking outside all day without plugging in and my range was reduced to about 90-100 miles. I think most of the range loss was due to the heater using a lot of power because at that temperature the heat pump does nothing. Only other significant issues I found were cold batteries take a while to warm up in order to start charging and cold batteries don't give 100% e-power.
Nope, I had to run summer tires in 10-20°F temps on average the 1st two months I owned the car. With the thread linked above it did go up to 3.3mi kwh it looks like. I didn't get to above 45 for quite a while into ownership.
Wow, today I experienced a GOM experience like @Nigel Warnes had. When I left my work I had 68% SoC but the GOM said only 48 miles of range. After driving 40 miles I arrived home with 40% SoC and the GOM says I have 43 miles of range. I thought I was going to end the trip with more miles on the GOM than it said at the start. That's just nutty. All I can think is when I drove less than a mile at lunch that must have messed up the GOM algorithm big time.
Snow totally and utterly sucked royally. I drove my car around the block and never took it out again in the snow. I, fortunately, had my spouse WFH at the same time I was and given my area is excellent with clearing roads, I only had to use his car a handful of days. Another fortunate thing is that when it was wet outside of snow it was above 45 at least. So it works excellent when cooler and rainy. It works great in cold and dry as well. Just sucked the one time I tested in the snow. I plan for snow tires to be purchased on 16" rims in the next two months.
Thanks for the replies. I'm working on a video talking about 'real world' range results, and I was guessing that actual range would drop into the 90s in cold weather. Sounds like that is fairly accurate. My warm weather driving so far has been excellent on range. My average for all calculated trips is 125 miles, with a high of 145 and a low of 113 (three adults plus roof crossbars). The crossbars impact my range more than I thought they would.
I've posted this link before. I haven't seen anyone stretch the SE's range further than the 177.65 miles (city) in this video. I wonder how much further he could have driven had he been willing to forego his "early" visit to an EVSE? For maximum impact, you should show your SE going 178 miles. Just sayin'.
Based on my experience last winter I think that's pessimistic, unless the temperatures are below zero. Too bad we don't have eDrive info anymore to gather more data this upcoming winter.
You could also try hypermiling it, if you really want to make a viral video. These guys did 606 miles in the Model 3: https://www.theverge.com/2018/5/29/17405906/tesla-model-3-hypermilling-driving-record At that point, it's more a test of human endurance than anything.
I have been using Tronity to log my data since March, and just spent some quality time doing some spreadsheet work to calculate range performance during that time. Most of my driving consists of short trips at low-ish speeds on city streets, with some longer journeys which include a blend of city streets and highway speeds. Filtering out those shorter trips (since range is a non-issue when driving less than 10 miles round-trip) and averaging consumption for 10℉ steps, I got the following: 4x℉ → 3.5 mi/kWh = 101 miles 5x℉ → 3.6 mi/kWh = 104 miles 6x℉ → 4.3 mi/kWh = 124 miles 7x℉ → 4.7 mi/kWh = 136 miles 8x℉ → 4.7 mi/kWh = 136 miles Average distance travelled for this data set was 23.3 miles. In February, I also reported my "worst" cold weather trip at 5℉ (for one of those longer trips) at 3.0 mi/kWh which would be 86.7 miles of range.
