1st session completed - interesting data - more later today…

7B23F27B-4CF0-4B3E-A150-9FF94B672F40.jpeg




UPDATES

Here is lap data from the 1st session - GoPro sucks - GPS doesn't work through the insulated glass - so I don' thave lap data (speeds and such) - lap times are approximate - analyzed from time stamps on the video - they may be off by as much as 1/2 a second…

Screen Shot 2020-11-09 at 12.06.16 PM.png





key highlights so far:
  • best lap time w/Sport Crono (manual timing) - 1:45.xx
  • morning session of 7 hot laps + 1 out lap + 1 in lap - 53% battery used (98% out to 45% in)
  • garage 30 amp NEMA 6-30 plugs - (24 amp charge rate - 4.47 kW) return 5-6% battery/hour
  • 2nd morning session was faster - (49% - 17%) - 1 out lap - 3 hot laps - 1 in lap
  • 17% to 14% (3% consumed) to get to fast charger in Seaside (EVGo 50 kW) - charging now
  • I'm on all-season factory OEM tires - I know I know - I plan to redo with summer sport tires when these wear out (I'm working on wearing them out today)
  • Taycan is pretty good on track for 5,100 lbs sedan - but it's no track car (any more than any big 4 door sedan)
  • VERY DISAPPOINTED - car was way way way down on power in morning session after hot lap #6!!!! About the same number of laps I get with my Model 3 at Laguna before power reduction
    • Battery temperature leaving hte garage before session #1 was 72F
    • returning to garage battery temp was 132F - car was way way down on power
    • ambient air temp this morning at laguna was 50F or less (46F for 1st session)
6 hot laps = 12-15 minutes of hard driving at laguna - so it's more than nurumbergring lap (8 minutes or less) - but so much for Porsche's vaunted 800V and improved battery cooling system - the car can _NOT_ run flat out for a full 25 minute track day session - I had to come in at 18 minutes or there about because I was sooo down on power I was a hazard on track - 2nd session went better, but only did 4-5 laps because I hit 17% battery after 4 laps (no fast charging at Laguna)

I'm sitting at EVGo charger in Seaside right now - charing for afternon

consumption is extreme - more than 50% battery for one abbreviated session (7 hot laps) - hard to track this vehicle without fast charging at the track - a full 25 minute session would use approximate 80% battey in my opinion but you can't run a full session of hot laps becuase of power reduction due to battery thermals - I'm guessing it's battery thermals - but the cqr threw no warnings, just reduced power when on full throttle…

after a 1 hour cool down - battery temp dropped to 81F in the garage - returned out for 2nd session - full power was restored - did a 1:45.xx lap 2nd session - but had to come in early due to < 20% battery - needed battery to drive to fast charger 8 miles from track.

video uploaded soon with 1:46.xx lap time from 1st session - I'm still editting hte 2nd session video while I'm charging.

car is good, but has all typical EV problems for track use - very very high consumption, and no stamina to run a full 25 minute track session at full pace.





I ran the following sessions
  • session 1
  • session 2
  • skipped - session 3 - fast charging run @ EVGo in seaside, Ca -
    • leave track @ 17% SOC
    • arrive EVGo @ 14% SOC
    • 2 45l minute sessions @ EVGo get back to 92% SOC
    • arrived back at track @86% SOC @ 1:20 pm
  • session 4 - 2:05 PM - 1 out lap, 4 hot laps, 2 cool down laps - 1 attempted hot lap but battery was too warm @ 132F - car had only 40-50% full throttle
    • session 4 out on track at 88% SOC - back in at 34% SOC
  • session 5 - skipped - no enough SOC % to do a meaningful session - and if I pack up and leave now I can get home with 34% battery no problem no more fast charging required.
We’re done for the day - GoPro thinks it had GPS signal, maybe we got some data - we’ll see

more thoughts later - after I get home and decompress

good car, handles great for hit’s size and weight, nanny’s are soooo subtle - full throttle consequence free anywhere anytime - brakes (PCCB’s are awesome) - but like all EV’s I’ve experienced it’s not up to the task of a full 25 minute session of hot laps - but I”ll enjoy the drive home!!!

need fast charging at the track at least 125 kW to deal with the consumption issues

car is in one piece
driver is in one piece
I had a super good time!

car is good for about 12-14 minuted of flat out driving (which is about 2 nuemburg laps) - after that it needs a rest - recovery is about 1 hour of down time.

what a tease!
Interesting good or interesting bad?

Thanks for sharing and hope you are having a blast.
Nice to see that you got to use the battery-warmer outlet.

Did you capture the battery temperature before and after fast charging? I'm guessing the battery was warmed either by charging, or intentionally by the controller for optimal charging.

I got 6 sessions at 20-30 minutes each on a single charge (100% start, 18% end) but the first two sessions I was out for a Sunday drive to learn a new car on a new track, and all six were seriously slower, especially braking, due to a damp track. Without extreme braking, more kinetic energy was captured vs. burned off. There's no avoiding the weight.

the battery actually cooled at the EVGo fast charger - arrived with battery temp at 93/92F - and 90 minutes later it was 87F

ambient temp in Monterey today was 55-58F - nice cool day lovely an clear California fall day!!!

Laguna seems to be particularly consumption heavy - there is no way the battery would last all day - I could see 80% consumption @ laguna in one 25 min. session - if the car could stay out that long

I have confirm 132F is a temperature at which Porsche will throttle the vehicle - 3rd session of the day for me (4th on the schedule) when the car hit 132F battery temp - I lost most of my power…

5-6 hot laps is all it could handle at Laguna - I even tried two cool down laps (1/3rd pace) - and then a hot lap - I was throttled by turn 6 going up the hill - :angry:

Fastest lap from Session #1 (1st Session of the day on HOD schedule)

- this was lap #2 (1 out lap, 1 hot lap, 2nd lap this one!)

I think I had a faster lap in session #2 - I'm still importing and analyzing video - stay tuned - I'll post the 3 fast laps today -one from each session of the 3 I participated in.

delete - I hate go pro - I had wrong times because the "fast" lap was split across two separate mpeg files - when I stitched the two clips together the lap looks closer to a 1:46.xx

Did you have regen on? That causes the battery to get hot.
While tracking the car people switch off regen.

Nice report and some nice footage from the track, thanks for sharing.

It would be nice to hear if you ever did the same track with some proper summer tyres, like Michelin Pilot Sport 4s.

But I must say I am very disappointed to read about your experience of throttling the power! That is not what Porsche have tried to portray. This is somehow similar to the experience from some French driver on the Ring. I think he experienced similar reduction of power on his second lap after one hot lap. This is not what I had expected from Taycan, even if I perhaps never get to experience is in real life.

I would really like to hear what Porsche have to say about this as they seem to have lapped the Ring several times with the prelaunch car?

@Neptune the vehicle was in Sports Plus mode for all 3 sessions - I did not turn regen ”off” but I also did not turn it “on”

where is the setting to disable regen?
