I think we can sum up the preliminary results.
M5 CS - 7:29.57 (driver journalist Gebhardt)
Plaid - 7:30,91 (factory driver Simonsen)
The results are close, but you have to consider the difference in the level of the factory and Sport Auto tests. The BMW is obviously faster here.
M5 CS - 1:10.02
Plaid - 1:12.50.
Nonprofessional driver Tom Holland. The comparison is on a level playing field, the BMW is faster.
M5 CC - 1:28.76
Plaid - 1:27.78.
Driver Pro Randy Pobst. Level playing field comparison, Tesla is faster.
Bottom line, the main problem for the Tesla is braking. Without carbon-ceramic and wider rubber, the Tesla has a hard time showing anything intelligible on the track. I think the fairly good times at Willow Springs are due to the fact that there are only 2 more or less hard braking points at that track. Also, on longer tracks, the inability to run the battery at maximum power for long periods of time also becomes noticeable.
In general, on short tracks with limited use of the brakes, the Plaid is faster. On long tracks with an abundance of hard braking zones the fastest is BMW.
I suggest a draw.
