In the above video, titled "156 Lessons Learned: Testing FF91 at Pikes Peak" (the course has 156 turns), Faraday Future talks about the race, including the moment near the end when driver Robin Shute had to stop the car and cycle power it before he could finish. Lead Powertrain Controls Engineer Brian Harries says the problem was a too-conservative software calibration of the sensors meant to detect a stuck accelerator. Obviously, they can now recalibrate that system so that sort of thing doesn't happen again.
At least it wasn't a battery issue, though. Faraday Future was also able to put its thermal management to the test in the grueling hill climb. Because of the mass of the car, it has to put down a lot of power compared to a smaller vehicle on the same stretch of road, and keeping the battery pack cool is a challenge. The Pikes Peak race represents a more extreme use case than most customers would put it through, and the fact that it performed well was a win for Faraday Future. "I think the most important thing we have done with this project is open up the battery limits," Robin Shute says in the video.
"156 Lessons Learned" is part of a larger video series by Faraday Future following the company's journey preparing for Pikes Peak.
