My first time at this great new track near Dallas, Texas! I drove for less than an hour and some of that was cooldown laps since it was about 94°F so I'm sure there is still a lot more lap time on the table. This is the full 3.1 mile course although the track can be divided into two smaller independent track layouts. I was still trying different lines through some corners so the line in this video is probably not optimal plus I missed some apexes. The red and yellow curbs are smooth and usable (except I personally didn't like using the carousel apex curb) although you can see PTM tends to kick in when coming off of the curbs under power so if you have traction/stability control off be ready in case you might need some steering correction in those spots. Before turning into the last corner I was going too fast and understeered while trying to brake and steer left to set up before turn in plus I over slowed. You can also see that I was not fully utilizing the available grip in many places by looking at the traction circle graph meaning I could have carried higher minimum speed through some corners, braked a bit later, and/or got back to full throttle sooner.
Turns 5a and 5b from Mosport are replicated at this track along with a heavily banked carousel from the Nurburgring! Those happen to be my favorite corners at this track. There is a chicane available after the right hand turn following the longest straightaway but it was not in use.
Here is a video from a more experienced driver at this track: https://www.youtube.com/watch?v=DY_xfB_Att4
Note: Cosworth Toolbox shows this track layout as 2.96 miles. I guess the 3.1 mile distance mentioned online may be counting the chicane. Cosworth is usually within a few hundredths of the advertised lengths of other tracks I have been to.
Sorry the PDR track map and lap timer stopped working when I took a short break. I overlaid a screenshot of the track map from when it was working; the start finish is at the red dot which is roughly where the video starts and ends. Because I did not delete another track's start/finish line (.map.gpx file) from the SD card beforehand I think that might have caused the issue. I created the track in Cosworth Toolbox from the first session and it showed 2:26.95 for my last hot lap (this one) which closely matched the lap time on the custom track I created with Harry's Lap Timer with 10Hz GPS (2:26.97) and the duration of the lap in my video editor.
