What impact will these changes have?
Now this is comedy analysis!
1. I have used this "fact" from
Kobayashi who says 36kg is 1.2 seconds lap time impact. I have assumed he means Le Mans.
2. I have used the relative pace of the top 50 laps at Spa. Same method as in the
Unified thread (without the IMSA/WEC unified bit, hence the Porsche and Cadillac are slightly different!).
2b. Vanwall may look a little worse than they are because they didn't get that many fast laps in.
3. The impact of the circuit is not considered
This table shows the relative pace at Spa to the fastest car (which was Ferrari), the weight change in the recent BoP changes, the theoretical lap time impact, and assuming a 210s lap the impact to the relative pace. So lots of leaps of faith here:
| Manufacturer | Relative pace Spa | kg change | LM lap impact (s) | New relative pace |
| Ferrari | 100% | +24 | 0.8 | 100% |
| Toyota | 100.21% | +37 | 1.2 | 100.41% |
| Cadillac | 100.76% | +11 | 0.4 | 100.56% |
| Porsche | 101.40% | +3 | 0.1 | 101.06% |
| Peugeot | 101.70% | 0 | 0 | 101.32% |
| Glickenhaus | 102.05% | 0 | 0 | 101.66% |
| Vanwall | 104.01% | 0 | 0 | 103.62% |
Takeaways:
1. There is no change in order
2. Ferrari pull away from Toyota!
3. Caddy gets closer to Toyota
4. Total spread reduces
5. This isn't a silver bullet for Peugeot or the smaller manufacturers
