The "P" is just because that was what was available.
Fraid not ... it was because they expect to UPsell you
I expect you would have been having "fun" in whatever they lent you though, so you probably wouldn't get a realistic figure on the cooking version either ...
I want to do it in the charge range of minimising battery degradation over time
Other posters are of one voice. Forget about battery degradation. You've got a couple of worries that are not real, but of the ones that are: Don't leave the battery charged above 90% sitting there, don't accelerate hard below 10~20%, if arrive below 20% charge immediately-ish. Even then if the car sits for an hour or two in either full/empty state don't sweat it.
car for well over 100k miles, maybe even 200
You need to plan for being able to do your journey in Winter/bad weather and after degradation. You are probably looking at 7% at 100K and 10% at 200K. The only thing we don't know is how much variability there is in high mileage batteries, but the early data from very high mileage taxis, where the owners didn't own the battery, and didn't give a fig, and rapid charged to 100% and left them sitting like that ... has all been very encouraging.
Don't buy / compare again a version one Leaf though
the new cars are supposedly 10% more efficient
I think it is more than that (and a "definite" rather than "supposed", you'd be able to push a S100D to 400 miles max range at a steady 65MPH if you had to)
There's a supercharger en route half way... coffee may be the worst downside of EV life, is a starting hypothesis I have - I'll have to drink more tea)
Is doing Emails part of your daily job? If so doing them will make the stop time-neutral. New model is going to Supercharge a few percent faster when existing Superchargers are upgraded (that is an in-situ upgrade, not the much more dramatic Supercharger V3 one, might even be software, the announcement made it sound "simple")
There will also be good home/work charging at either end so the battery can start warm
OK ... if you have charging at both ends then nothing to worry about (assuming there are enough hours, at the work end, to get recharged). Assuming 7kW its about 23 MPH charge speed, so if you are there 8 hours that is 160 miles ... not a 100% refuel.
the negatives of battery degradation over time and the effects of cold weather
In perfect weather if I have a journey which is 75% of max range I charge to 100% - detours, foul weather (torrential summer rain is probably worse than UK winter temperatures). Headwind is bad too ...
But if you have Supercharger half way, which you will "Never normally need", I'm not sure I would bother particularly ... you can do Splash-and-Dash if you need to.
Note that journey is quicker if you drive fast [up to 90MPH-ish] and Supercharge longer ... provided that there is a free (unpaired) stall when you get there. IME that is usually "Definitely", except at the 2-stall sites of course.
Would you consider regular charging to 90% to be much worse for your car than 80%?
No. Musk recommends that. My car is set to charge to 90% daily, 100% for trips, and then I change that to 50% (and leave it plugged in) if I am away for weeks on end. I've had it 3 years and done over 80K miles
Would you consider running it down to 10% so regularly to be similarly poor form?
No, except as been mentioned charge immediately on arrival and no hard acceleration.
But I absolutely don't plan a trip if my arrival is predicted as 10%. 10% is 20-25 miles, so enough for most detours and "dozy driver missed a junction", but percentage wise it may not be enough for bad weather. Slowing down in torrential rain doesn't help much (you get the aerodynamic penalty back again, but not the friction/rolling-resistance one). If you have optional charging on that trip then of course its fine, top-up if you need to.
I expect you saw the Energy Graph on your loaner? Put destination into SatNav and then "Trip Energy Graph" shows your consumption from your departure charge %age, to predicted arrival Percentage. As you drive you get an Actual line too, and display of predicted arrival percentage. If that falls dramatically I slow down and as I get closer, if it is above 10%, I speed up.
Draft a juggernaut (at a safe distance) if desperate
Road works and Traffic on UK motorways normally fixes my range
Would you expect a 5% motorway speed reduction to knock say 10% off your power consumption?
I think your actual commute is going to be better than your test
I get on the motorway, select AutoPilot at 75 MPH, and that's it. I give the car a decent follow distance, I let anyone pull in that wants to, if I get some twit up my ar$e who thinks I'm some hopeless octogenarian then when the traffic clears I turn on Warp Drive and show him a clean pair of heels, but that's just for my amusement of course ...
AutoPilot will make a huge difference to how refreshed you feel, on arrival, even compared to cars I previously owned with Adaptive-Cruise-Control. I never take my eyes off the road, always have one hand on the steering wheel ... I would not have believed that just those micro adjustments on the wheel, that I used to do with ACC on motorway, would make a difference, but it definitely does.
Driving consistently like that I have a wide range of actual journey figures and whilst generally worse in Winter / Summer I have good Winter journeys,and bad summer ones.
Worst case is Winter with a cold battery. Pre-conditioning (i.e. plugged into Shore power) helps, but that won't warm the battery. Charging battery for an hour immediately before departure helps, but it will still be cold (iPace does a better job in that regard). If you make multiple stops, in Winter, "travelling salesman" your range will be dreadful because each time you stop battery will get cold again, and you will have the "cold battery start penalty".
Once warmed up, trogging along the motorway at 75 MPH is OK.
On the days you are in range just drive. On max-range-challenged days then plan ahead, and use Energy Graph and slow down / speed up according to predicted arrival %age
Just looking at my logs for my range-challenged journeys
One day in February, 520 miles driven:
Leg-1, 8C, 174 miles, 373 Wh/mi Motorway Avg 55MPH
Leg-2, 10C, 64 miles, 371 Wh/mi Motorway Avg 63MPH
Leg-3, in range of supercharger, empty A-road across Wales, having fun
10C, 92 miles, 459 Wh/mile
Average 43 MPH
Leg-4, 11C, 160 miles, 380 Wh/mi Motorway Avg 55MPH
Looking at a couple of other Winter journeys 370 Wh/mile seems to be my "range challenged journey motorway-cruise leg" consumption
Makes no difference to range (other than stopping you "flooring it"
), and Chill does NOT have kick-down, so I never use it.
I always use that on long journeys. Habit. Definitely will only make a (tangible) difference on dual-motor models, probably not enough to worry about
The cold weather does have a big impact, as much as 20/25%
I don't reckon it is as much as that, on a longer Motorway leg.
Truth is we don’t know the 10-20 year effects
I reckon anyone planning 100K ownership is either high mileage, and will get to 100K in 3-4 years, in which case the existing Taxi data is comparable, or will be majority short-journey driver, in which case some loss of range may not matter too much.
My suggestion would be NOT planning to keep it that long. This is really new technology, there will be a point in the future where you may well think "this car WILL last for 1,000,000 miles" and maybe plan to buy a forever car at that point?
Try your journey(s) in
A Better Route Planner. You can choose current P-Turbo-Nutter model that you had as a loaner, and see driving time, charging time, and consumption, and then re-try it with one of the Beta "new long range 2019 models" and see how ABRP rates them. ABRP is well liked, its data seems to be accurate - notwithstanding no actual real-world data for models not yet launched. You could try the journey in the 2020-Roadster too ... if you like
If you are buying new get a referral code off someone to get you (and them) some free Supercharging. If you use mine and I win a Roadster in the draw you can borrow it ... trouble is, I won't know which referral got the Roadster and I will be lending it to so many hundreds of people I won't get to drive it myself
I think
@WannabeOwner has a different one for every day of the week
if I didn't know you better I would think you were taking the Mickey. I (truthfully) have 20 items in my TeslaFi schedule
a control system that can act on expected PV generation
Zapi Wall Charger will divert excess PV to car (rather than export it) ... but you have to be parked at home during the day of course
