We all know the performance of the car is impacted by the state of charge, and I've seen many graphs and videos about how it changes when on a dyno, but wanted to see the impact on driving performance at the track So, I hooked up the OBDII dongle and Scan my Tesla app to my LR RWD and headed out to the track.
A few things that were interesting to me about the data:
~ The brake overheat warning goes off when the estimated brake temps hit 600 C (1,100 F.) I have Mountain Pass Performance upgraded rotors and pads and had no problem with brake fade, but the chime goes off based on the estimates the system makes assuming you have stock components.
~ With a nearly full charge (above 90%), my RWD is producing 250 kw (335 hp) and 270 nm (200 lb-ft) of torque (at full throttle at 104 kph (64 mph) at the beginning of front straight. By the end of the straight it is producing 209 kw (280 hp) and 135 nm (99 lb-ft) at 177 kph (110 mph).
~ By a few laps in I was down to 60% SoC it was only producing 197 kw (265 hp) and 224 nm (165 lb-ft) at 62 mph at the start of the straight down to 151 kw (202 hp) and 113 nm (83 lb-ft) at 102 mph.
If you are tracking your Tesla then you already know this, but be sure to get your hot laps down early in the session for any chance at setting a PB.
