Yep, 43PSI cold. The EV Database has lots of good information on all aspects of most EVs. It gives the M3 SR+ MIC a freeway range (mild weather, no A/C) of 330Km which fits exactly with Nylund's figure of 330km at 130Km/hr. From memory it was nearly 400 at 90km/hr. I figure on 350km at our country road speeds. The database has already been updated with the new M3 with bigger battery - 57 useable Kw ie only 4.5 more than SR+, and 30km more highway range.
The database also shows how much more energy some other EVs use - Hyundai Ioniq 5, new Volvo and Mercedes, Skoda Enyaq up around 30% more than M3. Tesla has the jump on efficiency.
I seem to be wearing a hat whilst driving around town, with consumption in the low tens...

I can definitely plan on a first leg of a comfortable 400 kms under reasonable conditions.

Okay Chris, here is some range info for you. Trip is on the East Coast.

1. Outgoing. Sydney Avalon Beach (sea level) to Canberra/Queanbeyan. Elevation gain 577M (from sea level) with highest point Great Dividing range along the way at 763M. Conditions 25degC and no wind to speak of until the last 108km when a very strong headwind blew in at around 30-40km/hr. Until that point, the kwhrs were tracking better than ABRP and Tesla Nav predicted. i.e., the predicted final SOC was 22% but we were tracking at a Tesla estimated 31% until the wind and that pulled us back to the final figure, which was 25%. Max power was 260kW and distance travelled 320.4km. Boot, frunk and some back seat packed with stuff for kids and grandkids and total two passengers. Aircon was on 20.5 the whole way and we used 55.6kwhrs for a total of 173WHr/km. Most of the trip was 112km/hr and we sat at 2 above the speed limit the whole way. It was a quickish trip at 3hrs 45min. There was only 540 metres of roadwork.

2. Return trip was 334.3km with 69% SOC used (so, being downhill, better than the 75% SOC used for uphill). Total 51kwhrs for 141WHrs/km. Again, 500M of road work. Again, 2km/hr above posted speeds. A bit slower at 4hrs 8Mins. max power used at 160kW was lower than the outbound trip. Again, two passengers with our clothes and some food but most of the heavy stuff was jettisoned in Canberra and Queanbeyan. Temperature average was 21degC and we had about a dozen rain showers but only a couple of heavy ones. No wind to speak of.

So, projected maximum range from 73.3kwhrs of battery comfortably over 400km on the highway. There is some suburban driving in both these trips but the highways are the dominant portions. Around town we are averaging a maximum range of around 550km. But you did not ask that- just info for comparison.

Overall, we did two charges. One was 19mins at a V2 Supercharger & 20% SOC so rate capped at 120kW and decreasing to 80kW for an average of 99kW.

The other was a try of a Chargefox 350kW charger which started at 170kW for 20%SOC and also dropped to about 80kW at approx 60%. Both these charge rates were higher than the Bjorg Nyland tests of the LG battery versus the Panasonic in the Model 3LR and 3P vehicles.

Excellent. Well in excess of bladder capacity then!

Yes indeed. But we did buy a 3LR for long distance road trips so it would be a bit disappointing if it fell short of expectations. On the charging front, seeing figures like 1,200km/hr being added to the car at 20%SOC are quite good, although it does drop off so that the average for 20% to 80% is 620km/hr. You can get 300+ km of highway driving in about 30mins.
