Default Its possible to do donuts or burnouts in hybrid ?

Hi, I am looking for GS for me and I am thinking about 450h one since 350 is no available in Poland. I saw some post about disabling entirely traction control but its pretty hard to find some info about how much disabled tc is enabling to do.

There is a hybrid maintenance mode that turns everything off. You risk damage to the transmission due to the electric motor torque. It's a pedal dance. I don't quite remember the procedure but it did not seem difficult. Use at your risk. I'll try and update with the pedal dance.

Step 1: Set Ign switch to "ON" not ready (power button twice no brake)
Step 2: While in "P" fully depress gas pedal twice.
Step 3: Select "N" fully depress gas pedal twice.
Step 4: Select "P" Fully depress gas pedal twice.
LCD should come up as "Maintenance mode"
Step 5: Start engine (Brake +Start button)

Step 6: At your own risk, have fun I guess.

NOTE: Warning: The shop manual states in no uncertain terms must the car be driven like this as damage to the transmission could occur due to tc being fully disabled.

Don't get this car for donuts/powerslides/etc. You can disable TC, and there are LSDs available (torsen transplant detailed at the russian lexus forums or cusco RS from what I've seen, all involve grinding), but the throttle response can be maddening. In addition, the ability of the inverter to withstand sudden RPM changes from the electric motors is unknown. Google BackEMF.

I've been powersliding in the snow, but I watch the speedo to make sure that it doesn't exceed 60-70kph. Dry asphalt is something else entirely. I mean, there are clips of the gs450h doing donuts on youtube… it's your call.

Again, no stock LSD. The cusco looks to be a $1.5k upgrade, haven't seen any opinions on it.

USA spec models you can press the TC button briefly to defeat TC and/or press and hold the button to defeat Stability Control and TC.

Doesn't quite turn off all the way...unless in maintenance mode. But yes, this is true.
