I just love the efficiency…

Wow, 6.4 mi/kWh is awesome. That's model 3 efficiency.

 

Model 3 RWD Efficiency is around 220-250Wh/mile or 4-4.55mi/kWh. AWD drops it down to about 3.85mi/kWh.

Then again EPA rating for the MINI is 3.22mi/kWh....

 

I can’t be sure of this, but in my mind I’m imagining that BMW asked the EPA to be conservative in their rating; the WLTP is wildly optimistic, and in fact, the MINI site in Europe and the UK states the WLTP rating while also giving their conservative manufacturer efficiency rating that is more in line with the EPA figure.

 

I am super impressed as well. Some of my best drives are:

142 miles driven, 22% battery remaining, 6.3mi/kwh.

70 miles driven, 62% remaining, 6.43mi/kWh

On usual day to day commuting 5mi/kwh is pretty easy.

These’s a lot to be said for small lightweight and efficient.

 

My understanding is that manufacturers do their own testing. It was therefore MINI's choice to be so conservative.

 

All y’all must live in an Escher painting where you only ever drive downhill.

I did a little road trip just today and here’s what I got:

2585 km —> 2698 km … away
113 km travelled (70.2 mi)
100% —> 24%
76% used (22.0 kWh of 28.9 kWh cap.)
Range est.: 149 km (92.4 mi)
Eff. est.: 19.5 kWh/100km (3.19 mi/kWh)

24% —> 97%
73% charged (DC fast charger)
$4.23 cost (3.74 ¢/km; 6.03 ¢/mi)
~23 kW delivered (MINI app)
23.736 kW delivered (charger)

2698 km —> 2804 km … return
106 km travelled (65.9 mi)
97% —> 33%
64% used (18.5 kWh of 28.9 kWh cap.)
Range est.: 166 km (103 mi)
Eff. est.: 17.4 kWh/100km (3.56 mi/kWh)​

 

Are people in this group seriously getting 180 miles per charge?

 

I struggle to believe it.
Would love to see time-lapse video evidence (with start/finish elevation, too).

 

I think that I *might* be able achieve it, at least under just-right conditions, i.e , warmer weather, flat roads, limited speed, gentle driving. I say that because I'm recently averaging 140-150 mostly commuting, which includes about 50% interstate @ 60-70 mph. It will be interesting to see what happens this summer, when it's even warmer and air density drops further, but I have to use the A/C (which I haven't needed much yet).

ETA: I have hit as high as 178 for one round-trip already, and that was without really trying (got lucky with the red lights, IIRC).

 

No way for me. I'm closer to 3.5 mi/kWh in summer and struggle to hit 3.0 mi/kWh in the winter.

I'd have to manage to hit 1.0 to break even in energy costs vs an ICE S though so I'll take it. Turns out to ~$100/mo savings for me at the current gas prices.

 

I often get around 140 commuting, and 125-135 on highway. The best I can do are out and back trips in the mountains with equal climbs and descents up to around 11,000’.

 

I mean you can get 8.0mi/kWh in an i3 so 6.4mi/kWh sounds reasonable.

 

The only time I ever got over 6 mi/kwh was when there was traffic on the freeway, and we crawled for 30 mi or so. I never drive in green or +, though. Always in sport.

 

Here are my numbers for this morning's commute, carefree freeway driving over 60 mph in mid mode. No A/C, because it's not quite warm enough for that yet. But this is typical summer efficiency for me, even without trying to hypermile.

***********************************
May 11, 2023 at 10:00 ** 65°F ** Wind: 7.662 mph from SE ** Humidity: 0.74% ** Driven: 42.3 Mi ** Start-Batt: 100% ** End-Batt: 73% ** Mi / kWh: 5.42 ** GOM Reading: 83 Mi ** Range Left: 114.35 Mi ** Total Range (From 100% charge): 156.65 Mi ** Total Range (From 100% charge): 156.638 Mi

 

I've had my SE for around 2.5 years, and since the day I have had it, the average is 12.5kWh/100km. This translates to a full range of 243km or 144mi. This is spot on WLTP. I dive exclusively in sports mode, punch it from the lights, but stick to the speed limit. I drive maybe 40% on the freeway with speeds from 80-110kph. The rest is at suburban speeds (40-60kph). This equates to 5mi/kWh. The aircon is permanently on and set to 21C. As it is only ever below this on winter mornings, my use is predominantly cooling. I could easily believe 6mi/kWh if you ran green+ and were gentle. 5 is easy to achieve (unless you are going round a track).

 

@vader I’ll be in Brisvegas next Friday for the weekend, heading to Lions v Suns game!

 

I guess I'm having too much fun driving around with a lead foot. I'm always in Green+ mode. And I always drive with the windows down and sunroof open. My average for the roughly four months of ownership, and 1100 miles, is 4.5m/kWh. I've driven more in the last four months than in all of last year.

 

Recent trip to Atlanta and back 4.6mi/kWh. Mostly 5-10 over. Some traffic snarls which does wonders for economy, but not my mood. Commuting this time of year, low 4s. 5x 52ish second autocross runs gobbled up 23% of my charge today. Om nom nom nom.
I get significantly less mileage if I have my sticky autocross tyres on, even driving sedately. Around 25% lower than the OEM 'kooks. Do the low-scorers here have non standard tyres?
