Yikes! I would have expected it to do much better in warm temps and 45mph average speed! If you had a normal average highway speed (60-65mph) you would likely be well over 45kWh/100 miles!
Same as my first long range trip last week...about 190+ mi. max range...which everyone thought is quite acceptable and expected. I was in Comfort Mode (NOT Eco mode) AND I drove some City driving in Miami for about 15 of the 143 mi. today. I suppose I could drive in ECO mode for > 200 mi. max range on the highway but why bother if I drive < 170 mi. in a day and my EV gets 190+ mi. max range in normal, Comfort mode? I think the 45mph average was because of traffic and Dynamic Cruise Control adjusting for cars in front of me and the ~ 15 mi. of city driving at 25-45 mph. I typically drive normal highway speeds as the speed limits here in South Florida are usually 65-70mph. Also - what's wrong with my battery efficiency at 41.4 kWh/100 mi.? It's better than 45 kWh/100mi...it was typical highway driving with some traffic, so the speeds vary a bit. What don't you get about that?
Not understanding your point and concern; it's confirming the 190+ mi. max range for Highway in a warm climate VS. your 140-150 mi. range in an Arctic-like climate of MN & ND. That is a place I wouldn't even think of driving a limited range EV (if often driving 100+ mi. in 1 day) until the technology of upcoming EVs allows for a 350-400+ mi. max range on a full battery.

There is nothing ‘wrong’ with your car’s energy consumption. I never said there was. I simply registered my surprise at the higher consumption than I would have expected, based on most others’ comments in regards to my own consumption. It surprised me that it didn’t have better performance in those conditions, nothing more, nothing less
It’s goes without saying that 41.4 is better than 45? Not sure what you don’t think I ‘get’. In my experience, an average speed of 45 mph over 140 miles is not normal ‘highway speeds’ over a majority of the drive. You obviously had some very slow speeds to offset the 70+mph 95% majority highway. But that is neither here nor there.
My comment was simply stating I was surprised the energy consumption was that high in mild weather and a sedate average speed. I would expect better performance in milder weather (because pretty much everyone has stated as such).
That is great that you are pleased with that performance and it is in line with your expectations. That really is a good thing for you.
By the way, if you were to achieve that 41.4 over the entire usable capacity of the battery, you should be able to cover about 205 miles. That isn’t bad, but I would hope to be able to do that at sustained highway speeds, in which the average speed for the trip would be closer to 65-70mph. Sounds like the Tesla roadster will be able to do that easily.
