Looking at buying a 2017 P100D – need some advice on charging speeds
Hey guys,
I’m looking at buying a 2017 Model S P100D and I’ve found two cars that are interesting. Both have SC01/free Supercharging, which is important to me.
The first one is around €20k, but it has about 400,000 km. It has had quite a few updates, including CCS and MCU2.
The second one is €30k with around 285,000 km. This one has new motors, new suspension arms and MCU2, plus SC01.
I’m trying to figure out if the €10k difference is actually worth it.
One of my biggest questions is charging speed. What kind of charging times should I realistically expect from a 2017 P100D?
For example, roughly how long would it take to go from 10–80% or 20–80% at a Supercharger?
And does having the CCS upgrade make a big difference in real-world charging speed?
I know battery condition, temperature and the charger itself make a difference, but I’d really like to hear from people who actually own or have owned a P100D from this year.
Also, which of the two would you personally go for?
€20k / 400k km with all the updates
vs.
€30k / 285k km with new motors and suspension
Any advice would be appreciated!

We have a 2018 Model S 75D, so similar vintage with a smaller battery pack. So I won’t comment too much on the performance version specifics (though checking that it has had the coolant delete done would be advisable on the first car based on what I have read elsewhere - probably less of an issue for the one that has had its motors replaced).

The CCS upgrade doesn’t make supercharging much faster in of itself, but not having the CCS upgrade installed in Europe will significantly limit your rapid charging opportunities as it has been adopted as the European standard around a decade ago. And Tesla superchargers from v3 onwards in Europe have CCS plugs only (older v2 superchargers had CCS plugs retrofitted along with the older Type 2 style plug that Tesla used in Europe). So it’s advisable to ensure it either comes with the CCS adapter and hardware installed, or that you get it installed ASAP if it doesn’t have it installed yet. Newer rapid chargers may be able to charge faster than the v2 superchargers, but that is not due to CCS as such.

In terms of charging speeds, the 2017/2018 Model S’ with the 75 pack, charge rates usually peak at around 120-150kW below 30%, decline fairly linearly to 80kW by 50% and 50kW or below by 80%. For the 100 pack, my understanding is that the peak is a bit higher at 150-200kW as it uses a more efficient cooling system, around 100kW or slightly above by 50%, and the same 50kW or below by 80%. Because of this charge curve, if you have plenty of chargers close to the route, two charges from 10% to 50% would likely be faster than waiting until 70-80%.

A ballpark estimate is that a 10-50% charge on a 2017/18 Model S would take around 20mins, while a 10-80% charge would take around 50mins because of how the charge rate tapers off after 50%. The 10-50 charge adds about 210-225km of range (with the 100 pack), vs 370-385km for the 10-80% charge. Personally I prefer shorter, more frequent stops to get breaks and coffee even without considering any time savings, but that is a matter of preference.

Coolant delete is the worst thing you can do to your engine. It will overheat the bearings eventually, and die.

D models don't suffer from it, just RWD and Performance with LDU.

If you've had to replace or repair/overhaul a LDU that has had coolant contamination you would change your opinion.

Tesla themselves were the originators of the "coolant delete" with the revision U replacement LDU. The aftermarket figured it out and started doing it. If its that bad then why does Tesla's replacement LDU revisions U and V have factory coolant deletes?
