The battle for the championship is entering a decisive phase with Jack Aitken at the forefront. If the British driver manages to leave Indianapolis with over 166 points ahead of his rivals, he will only need to cross the starting line in the final of Road Atlanta to secure the title. However, the competition at the Indianapolis track will be intense.
The Caddy V-Series.R has maintained a relatively stable BoP for the Battle on the Bricks, but some key competitors have received a boost. In particular, the 2026-spec Porsches have achieved greater competitiveness, despite still carrying a higher weight.
In a notable surprise, the 2026 Porsche from Penske has gained a more favorable BoP in low-speed sections than its 2025 version from JDC-Miller Motorsports.
Power-Weight at Low Speed
The power-weight ratios for Indianapolis vehicles below 230 kph are as follows:
- Aston Martin Valkyrie – 1.962 kg/kW
- BMW M Hybrid V8 – 1.981
- Acura ARX-06 – 2.023
- Cadillac V-Series.R – 2.073
- Porsche 963 – 2.098
- Porsche 963 old – 2.116
The Aston Martin remains at 1,020 kg, a weight it has maintained since Watkins Glen. The BMW M Hybrid V8 retains the BoP from Road America, while the Acura sits in third position with a significant gap.
Surprises come from the bottom of the table: for the first time, the 2026 Porsche has obtained a more favorable BoP in low-speed sections than the privately introduced 2025 model. Furthermore, the gap between the 2026 Porsche and the Cadillac has reached its lowest since the start of the season at Daytona, opening doors for Laurin Heinrich to fight for his title aspirations.
Changes to the BoP
Since Road America, the 2026 Porsche has been the most advantaged:
- Porsche 963 -0.027 kg/kW
- Acura ARX-06 -0.007
- Aston Martin Valkyrie +-0.000
- BMW M Hybrid V8 +-0.000
- Cadillac V-Series.R +0.004
- Porsche 963 old +0.017
These adjustments are relatively minor, as the difference between the two track profiles is not as drastic as the one from Watkins Glen to Elkhart Lake. However, the specifics of the Indianapolis circuit involve more tight corners and a demand for good mechanical grip in low-speed turns.
Porsche stands out with its improvement: for the first time since Sebring, the factory Porsche drops below 2.1 kg/kW, highlighting the difficulty in finding an adequate BoP for the new LMDh following its victories in the first two endurance classics of this year.
Power-Weight at High Speed
Above 240 kph, the power-weight ratios are:
- Aston Martin Valkyrie – 1.962 kg/kW
- Acura ARX-06 – 1.992
- BMW M Hybrid V8 – 1.997
- Cadillac V-Series.R – 2.037
- Porsche 963 old – 2.067
- Porsche 963 – 2.078
At first glance, it seems there are few changes since the last race. However, adjustments relative to Road America reveal small tweaks that make a difference.
Overall, while Porsche has managed to adjust its competitiveness, the current numbers primarily benefit the cars of Acura and BMW, which seem to be the strongest competitors.
Conclusion
As teams prepare for the competition, Porsche has improved its situation, but will need a precise strategy during the race. The teams from Acura and BMW, which already showed competitiveness in the previous edition of the race, will be the main favorites.
Cadillac, with its higher power-weight ratio, will have a harder time, while the Aston Martin must overcome a BoP that does not favor them, especially after a season of difficulties.
