Nürburgring lap time for P85+?

[PaulusdB]

Just out of curiousity I test drove the German Autobahn near to the Zevenaar SuperCharger.
My P+ reaches 214 km/h and stays there for 10 km, but then limits to 204 km/h. Forgot to note the exact kW's, but very soon the limit of around 200 kW becomes apparent (orange dotted line).
So this means no impressive laptime on the Nordschleife.

I drove the German Autobahn as well.
My 85S reaches 202 km/h.
After a couple of times full acceleration from 100 to 200 km/h ( 62 - 124 mph) power was limited to 160 kW.
After about 30 seconds at lower speeds full power was available again.
In my opinion the MS is not ready yet for the Nordschleife.

The acceleration itself is very impressive. It goes on and on. When reaching max. speed it feels as if the car is braking.
Downside: steering is indirect at higher speeds. I am still wating for the Autobahn upgrade that was promised by Elon in october 2013.

Ok, he hit the limiter about 3.5 minutes into the lap. His total time was 10 minutes 29 seconds. More details once he posts them, but he's currently driving around and visiting Tilburg etc. At least one of their laps was disturbed due to a BMW doing a major crash with a roll over that had the track sprayed with parts

That's a bummer. It seems like that would seriously cut into high-speed autobahn commuting let alone fun on the Nordschleife.

Perhaps there needs to be a race mode that pre-cools the pack and motor then runs cooling full blast?
Alternately try again in late autumn when the weather is cooler but before there is snow.

Maybe someone could design a heat exchanger and we fill the frunk with dry ice to cool it I'd give up my frunk for the ability to run laps.

Well... At least it seems it beat the Prius time by 1 second if I'm understanding this correctly?

But lost by 6 seconds to a Ford Transit Van. Let's just say this car is not made for performance driving (rightfully so imho) and forget this thread.

eww. I hope my next EV put up a competitive time on the 'ring.

What would happen if you race a Model S in an arctic climate where it is -40º? Would the very cold temperatures allow the temperatures to stay low without power limiting?

Someone posted on here that they were told it's a timer and not a temperature sensor that puts the car into a power limiting mode. I have no idea whether that is correct however.

I don't think that's the attitude we should take. If we want the Model S to be a real alternative to the M5, E63 etc. we should be pushing the aftermarket and factory to enable it to perform basic sport sedan functions like one lap of the ring or 10-20 laps of your local track.

No offense to whoever was driving, but if you took the driver who drove the Transit Van (which I expect was a pro driver) and put them in a Model S, they would probably be able to do a better time than they did in the van. We have to be careful about comparing times between drivers of vastly different skill levels.

Something that's really easy to implement even by Tesla would be a toggle-able power limiter. Then the driver can dial in the optimal power limit to use during a lap without overheating. I think a main problem with the current power limit is how it cuts in half no matter and also at inopportune times.

Model S full power is 320kW? If so that's already 3.7C current continuous. At 1C, Model S would deplete the whole battery in one hour. At 3.7C full to empty in 16 minutes. I guess the limits are set to protect the battery.

16 min would be enough for a ring lap or two. If Tesla really cared to be a player at the ring they could put a supercharger at the track. Or maybe you could have a diesel generator with a charger on a trailer to leave in the paddock-- something the size of tire trailers that some people tow.

Assuming the limit is temperature in some drivetrain component, with better instrumentation I am sure you could vastly improve the lap times.
You would have to drive intelligently to manage the drivetrain temperature. Don't use max power for short sections, only use max power to accelerate into the longest stretches.
Start braking a little early and use both feet to avoid regen. Ease off the accelerator early on medium length sections and coast briefly before braking.

I think sacrificing a little speed on the short stretches and conserving the temperature for the longer ones would lead to vastly better lap times.

Hi @jbruce, I agree.

It seems leafs and I-mievs can charge at the track.

I just guessed it might be bad for battery?

That van driver was Sabine Schmitz.

Time to get Sabine in a Tesla and a development team to go make it happen.
