This video is what keeps bringing me back to thinking I'll be ok on the track for 10 minutes at a time of pushing the car. The temp gauge is climbing like crazy in this video but they do push it pretty hard for almost 10 straight minutes. I'm sure Misha is driving it harder than I will as well, most likely.

 

For engine oil temps, you could always add the cooler from the Japanese "S" models, I suppose. As for the transmission, which seems the most limiting factor, I gather that using "Sport" rather than "Sport +" mode makes a meaningful difference. You really don't want to overheat your transmission fluids - bad things may happen thereafter...

 

Saw this video somewhere, but I distinctly remember watching the track images at the top most of the way through, This time I was pretty glued to the the dash watching the gears, speed, rpms, oil temp etc. and especially enjoyed the blue hashmark on rpms that briefly indicated prior max rpm after gear change. Haven't noticed this on mine. Could be due to me not pushing the limits or just missing it. Glad you posted.

Edit: I just assumed there was an rpm limiter that would kick-in past red line. Noticed several times he exceeded red line without an apparent cut-out.

 

Yeah I have surmised this as well. Running in sport is probably best though when I decide to push the car for a lap I will put in sport+ to avail of the suspension dynamics in that mode.

I thought that cooler on the S models was a transmission cooler rather than oil cooler? Either way I don't know how much effort that is, seems costly and I haven't found a full parts list either.

For engine oil temps I am going to run a diesel weight (rotella 15w40) and hope that provides some additional heat resistance beyond the normal 5w30. Not much I can do beyond that.

 

The blue mark is a setting that can be enabled via the cluster menus, located in a similar place to where the option to change the color of the tach after a specified RPM lies.

 

I need to go back into that cluster menu and poke around a bit. Once the car’s set up to personal preference, there’s always something that gets overlooked. I don’t remember anything about the blue RPM mark.

 

Yeppers. Never knew this. Unfortunately, after leaving the dealership where the young tech helped with personal settings, I fubar'ed a month later trying to explore and after 10 min trying to right things accidently discovered a setting showing current active gear, which I had wondered why Lexus omitted.. Our little LC gem continues to be full of pleasant surprises at my house.

 

I don't know if anything changed with the gauge cluster settings on the 2024.

yup thats the menu, same in my 24.

 

@Hythe
Yes. Those who have participated in the Lexus LC 500 track events confirmed that the instructor/professional drivers advise to use the sport mode rather than sport + mode. They drive these cars hard all day on the track with apparently no overheating issues (Engine and transmission) if this recommendation is followed. These instructors would certainly know best.

 

The difference is that those cars are run 3 laps at a time and then allowed to cool down for 10+ minutes while they switch out groups or give you a debrief/track lesson, so there is never really the opportunity to overheat. That's a 6-7 minute stretch of driving at most given most tracks they are on aim 120s-150s a lap, and the driving is not done at 10/10 pushing the car (instructors somewhat limit how much you are pushing the car, and most drivers are novice anyway).

I ran my sets of 3 laps on Road Atlanta in Sport+ and while I did not hit any transmission temp warnings, I did get the engine oil temp up to 3/4 by the end of the 3rd lap. Others in the group did run into yellow Trans Temp warnings.

If you are trying to run an LC even at 8/10 for a 20 minute track session it is almost guaranteed to overheat without planning in some cool down laps.

Thanks for your personal track activity feedback. Have you encountered any overheating issues with spirited street or back road driving ?

 

​​​​​​I have playing silly highway games. About 3-4 minutes of hard pulls and downshifts and engine temp starts creeping up.

 

The V8 sounds the same and elicits the same vocal sounds in German!

 

Configure the custom mode to use sport mode for engine and Transmission, then use Sport + for suspension which will be ideal for track use and lessen Oil and Transmission overheating events in the same time you will get the driving dynamics of Sport + mode.
