Looking to make the jump.

Few questions if I may.

Plan is to get a new one (have retired so this will probably be the last car I own before moving to a zimmer frame)

Is the LFP battery OK to charge to 100% all the time and if so does it take ages to get from 80% to 100%?

Is it possible to set the car up so there is no lane assist/distance control easily ? I would rather have full control than any automatic intervention for most of the time. No problems using it for longer trips but not day to day stuff.

Thanks

I'll try and help.

Tesla recommend you charge to 100% once a week. That's always seemed like an odd recommendation to me because charging surely depends upon how often you use the car. Anyway, I've charged mine to 100% at nearly every charge and in 2 years, 8K miles of driving, the car has lost an indicated 12 miles of range.

Yes, it does take quite a long time to get from 80% to 100% and if you charge at a Supercharger point, it takes a few more minutes for the 'calibration' to finish. I can't be any more specific because I've never actually timed it which should tell you I don't find it to be a major problem.

The lane assist is a pain sometimes, especially when cruise control is in use. But I think it's more disconcerting for passengers because as a driver, you sort of expect the intervention. I honestly don't know if it can be fully disabled which again indicates that I've never found it to be a massive issue.

I'm sure the distance control is only activated when using cruise control. I say I'm sure because I don't remember it kicking in when cruise control isn't being used.

The 100% recommendation on the LFP battery is to aid the battery management system from keeping tabs where it is, otherwise batteries are generally happier a little below that. You need ask yourself really why you want to charge to 100% every time, I've had an EV for 9 years and I rarely go below 30% or above 80% unless I'm doing a big trip.

When rapid charging (superchargers etc) it will slow down noticeably as you approach 100%, but home charging it won't make much difference as the rate is typically only 7kw. You should find most mornings you'll wake to a car at the state of charge you require.

If you're asking because you can;t charge at home and want to rapid charge once a week to 100%, then it will be painful at the end, but I thinhk you'll find you just never do it and will stop at 90%.

The driver asistance aids are a bit of a mixture. There is absolutely no obligation to use the autopilot software for speed and lane steering, but there is no "simple" cruise control either. At best you can have just adaptive speed but Tesla are trying to remove even this half way house. You will find that lne departure warning will be there regardless although i find it doesn't really get in the way, similar for forward collission warnings. These are systems that up to a point all new cars will have as they're increasingly part of new car regs. You nay also find speed nags are now a thing if you sometimes like to push on a little when its safe to do so.

One thing you might need to be aware of is the whole Tesla ecoystem is app driven. If you want a service or a repair for example.. you book it through the app. The idea of being able to talk to someone is a fairly alien concept at Tesla, at least before you're in the middle of a service ticket. You may well also need regular breakdown cover as punctures and the like can be very hit and miss with Tesla, if they agree to cover them at all.

Thank you for your replies.

The 100% question was related to me having solar panels and wanting to make use of the 'free' electricity during the day.

Would not want to harm the battery.

Thanks again :-)

It varies. While I do agree that Tesla tries to do as much service planning as possible through the app (which works quite well), I've had good experiences with just calling my local Tesla service centre and dealing with a human.

Also, the one time I needed a mobile mechanic (because of a recall), he gave me his personal phone number, saying 'if there's anything wrong, just call me'.

Had mine for two years 45k now, I charge to 100%, twice/three times a week to maximise the distance I can go. When Supercharging yes the last 20% is slower at home no different although seems to add around 20 minutes on when at full charge.

I think new it was 281 indicated miles, now at 269 indicated miles, most of this was lost in the first 10k. I charge most days too.

I think the new one isn’t as quick which is a shame, it gets a little slide on when booting it around a corner biggrin

Will a new RWD Highland Tesla 3 do 200 motorway miles at 70mph without charging?

Probably. Working on 57.5 KWh battery, If your efficency figure is:

3 mi/kwh = no
3.5 mi/kwh = only just
4 mi/kwh = yes

I've had mine a week and getting no less than 4, but I have no idea how that'll change in winter. I did a 200 mile journey at the weekend, although that was single carriageway 50-70mph type journey and had 19% left at the end, from 93%.

Bear in mind if you were looking like you werent going to make it at 3.5 mi/KWh, you can plug into a supercharger for 5 minutes and that would boost you enough to get to the end. You don't have to sit there for the full charge.

I'd add the riders that in winter your economy will be worse so maybe in summer but maybe not in winter
I'd add a second rider, you don't ever want to plan on arriving somewhere with a empty battery. Even if you start at 100% you'd not be very sensible to plan to go below 10% - getting held up by anb accident, a diversion, anything.. and 10% can be gone

Somebody suggested abrp which suggests it’ll do it with 23% to spare - courtesy of a few 50mph sections on the m4 perhaps.

The alternative is a new model polestar 2 long range dual with the 82kw which suggests it’ll arrive with 32% left.

Any thoughts on either.

Yes.

Used mine last month in northern Europe. Just shy of 5 miles/kW driving 70-75, which equates to around 275 miles range. From previous experience with my 2020 Model SR, this will drop to to 240 in the winter.

My commute to work is 35 miles each way on the M40/M42 plus a bit of back roads, 80 miles in total has consistently used 28% battery.

Thank you, that’s useful guidance.
