To try and help with the rankings, but not the be all and end all here is a look at lap times.
This can be considered the relative pace of the the cars to the fastest at the most recent IMSA and WEC race.
| Rank | Manufacturer | Lap% |
| 1 | Ferrari | 100.00% |
| 2 | Toyota | 100.21% |
| 3 | Cadillac | 100.88% |
| 4 | Porsche | 101.28% |
| 5 | Acura | 101.34% |
| 6 | BMW | 101.45% |
| 7 | Peugeot | 101.70% |
| 8 | Glickenhaus | 102.05% |
| 9 | Vanwall | 104.01% |
(Comedy) Method:
- The average of the top 20 lap times for each car at Laguna Seca was considered and the top 50 for Spa (considering the different race lengths)
- The fastest car from each race was considered. The lap times compared to the fastest car overall. Hence Ferrari (only in Spa) was the fastest and is 100%
- The Porsche and Caddy fastest were averaged in Laguna Seca and Spa and aligned.
Notes:
- A great deal of thought did not go into choosing top 20 and top 50.
- This is only the most recent races for IMSA and WEC
