6 seconds at 20% charge is pretty awful really and at 1C it wasn't even that cold. 20% is also not an unreasonable SOC to be driving with either particularly given the car charges fast at that point. Do you have the latest firmware? I live in Norway and we spend months between -5 and -25C and the thing that concerns me most is that you expect the car to react in a particular way when you need it. If it is 2 or 4 times slower than it usually is, that could be an issue.I'm an expat in Denmark, so I've been lucky enough to have my 2021 M3P for a few weeks now - no long waits Before I bought it I did a lot of checking after watching Bjørn's videos and what surprised me was that there wasn't a lot of reliable information/data out there - sure there's his test(s) and a couple of other people posting some isolated figures, and of course LOADS of discussion/opinions, but very little what I would call evidence. I'm not saying it isn't an issue, but it surprised me that there weren't more detailed comparisons for an issue that could be so serious. Hundreds of '5 things I like/dislike about my Tesla' - some of which are very informative - but it would be good with a better balance between the video content. It's good that RSymons, CarWow (and a couple of Tesla Gurus vids) are now releasing some good comparisons content.
I posted last week that I got a 6.0 sec 0-100km with a 20% SOC in a car that had stood outside all night with 1 degrees outside temp after driving 2 kms. Today I did a few runs with a warm battery and 11 degrees temp. At 19% SOC I got several runs at 4.1 secs with a HP reading of between 380 and 415 from Teslalogger. At 14% I got 6.6 sec and 270 HP, and at 9% 7.1 sec and 234 HP - all figures with a stopwatch but erring on the side of caution. Luckily those are figures I can live with. It's not 0 degrees all year round and I'm not often driving with less than 20% SOC. If I start to worry about being faster than a LR, I can take comfort in the fact that for the majority of my driving I will be.
Anyway, for me it was what I felt was a better sorted chassis that swung it for me, and the fact that in Denmark the P is only approx. £3000 more than the LR. In fact the M3P is probably the only car in Denmark that is actually cheaper than its equivalent in the UK (by £2000)which is amazing if you live here - anyone for a standard BMW 520? -yours for the equivalent of £70,000 or an Audi RS6? -£215,000) - so a no brainer
