2:48

This is a hotlap of Bedford GT in a stock Tesla Model 3 Performance.
With some sticky rubber, suspension, and brakes, I reckon this car would get down into the low-mid 2:4x. You don't get many laps at full power though so it's not a great track car. It'd make for a great sprint event car though!
Telemetry from Tesla's onboard track mode recording. The brake pressure overlay doesn't factor in regen braking though so the trace looks a little weird at times.

Yes agreed that a circuit like Bedford GT really doesn't suit it. A few of us compete in hill climbs and sprints and this is where it does well. Also on a track like Brands Indy or Thruxton. Which pads are you using?

[@thedarkkarters]

I swapped to Carbotech pads and uprated fluid around 4 years ago. I've done three track days and they still have a lot of life left on them 👍 I saw peak deceleration of 1.2G so the stopping power is good but the brakes overheat big time

@@thedarkkarters Good choice, that's what we recommend for owners who don't want to spend the money on a BBK. The rotors are the weak point, just not good at shedding the heat!

[@TeslaGurus]

The brake trace is purely hydraulic brake pressure. If you have regen on 100% you won't need as much pressure to decelerate at the same rate as 0% but that's really the only difference. Without upgraded brakes of some sort you'll really have to stick with 100% regen though as they usually overheat on most circuits otherwise. But, yes yours will be Intel Atom GPU.

[@thedarkkarters]

That makes sense. I had regen on 70% but that was probably still too high. I have different pads and fluid but only get a couple of laps before the brakes overheat. The car would be great for sprints but it's frustrating on long tracks like Bedford. It's annoying the drop off in performance as the battery gets under 50% too.

I'm guessing your car has got the Atom GPU as I can see some stuttering in the data, which is caused by a bug which repeats and sometimes corrupts the data. It can even cause the car to disengage from Track Mode while you're driving, which is annoying to say the least! If that happens, please report the bug via the app with a timestamp so Tesla gets another report from a different owner. We need more reports like this to have a hope of getting the issue fixed, because as time goes in it will only get worse. Thanks!

[@thedarkkarters]

Yeah it's a 2020 car so I'm assuming that's the Atom GPU? Interesting. This is the first time I've actually used the track mode data, I didn't realise the stuttering was a bug. I'm assuming the brake trace doesn't factor in the regen braking either?

@@thedarkkarters The change to AMD Ryzen was in 2022 so definitely an Intel Atom car
