WEC BoP: Is Austin favorable for outsiders?
Championship leader Ferrari and Sao Paulo winner Cadillac are once again the most heavily penalized by the latest WEC Bop. For them, this new round won’t be easy at all
We’re heading into the weekend where the WEC returns after the summer break, following the last round in Brazil two months ago. That race saw the Cadillac V-Series.R take a dominant win, with a strong performance from the Porsche 963 as well. In contrast, the Ferrari 499P—still leading the championship with 175 points—struggled due to a harsh BoP adjustment that made it the heaviest car on the grid.
And it will be the same story again at the American round: both Ferrari and Toyota will remain at 1069 kg, a weight that doesn’t help performance on a circuit like COTA, where agility is key through many fast corners. Cadillac and Porsche have been hit hardest in this WEC BoP update, gaining 19 kg and 12 kg respectively.
Power output below 250 km/h has also been tweaked. The Aston Martin, which lacks a hybrid system, retains its unchanged 520 kW. Porsche, on the other hand, loses 13 kW and now sits at 488 kW total. Once again, the Ferrari 499P is the least powerful on the grid with just 480 kW available.
Looking at the raw numbers alone, Aston Martin and Peugeot clearly appear to have the most competitive cars in terms of performance. However, that doesn’t automatically make them favorites for the race in Austin. We saw in Brazil that, despite having similar BoP values, neither team truly shined.
But here’s the twist: with the added weight in this new BoP round, Porsche and Cadillac might suffer even more and risk losing ground further in the standings.
