The competition on the Indianapolis track is intense, with Jack Aitken seeking to reinforce his position in the championship. If the British driver manages to exceed 166 points against his rivals, he will be able to secure the title simply by being present on the starting line for the final at Road Atlanta. However, the Indianapolis race promises to be a big challenge.
The Cadillac V-Series.R maintains a relatively stable BoP for this test, but many significant contenders have received certain advantages. Notably, the 2026 Porsches have begun to approach the level of competition again, despite carrying a higher weight.
In a surprising welcome, the 2026 Porsche from Penske has obtained a more favorable BoP in low-speed sections than its 2025 counterpart from JDC-Miller Motorsports.
BoP below 230 kph
The power-to-weight ratios of vehicles in Indianapolis 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
- Old Porsche 963 – 2.116
The Aston Martin maintains its weight of 1,020 kg, while the BMW M Hybrid V8 retains its BoP from Road America, with the Acura in third place, but with a considerable distance.
(…) the difference between the 2026 Porsche and the Cadillac V-Series.R has reached its lowest level since the start of the season in Daytona, providing Laurin Heinrich a real opportunity to fight for the title on his return to the Porsche team.
BoP above 240 kph
As for speeds above 240 kph, the situation remains similar:
- Aston Martin Valkyrie – 1.962 kg/kW
- Acura ARX-06 – 1.992
- BMW M Hybrid V8 – 1.997
- Cadillac V-Series.R – 2.037
- Old Porsche 963 – 2.067
- Porsche 963 – 2.078
While the situation has not changed significantly since the last race, the adjustments relative to Road America reveal some minor improvements for vehicles like the Acura and BMW.
Conclusion
These latest improvements place Porsche in a more competitive position, although Acura and BMW seem to be the main contenders for podium access. The Acura ARX-06, with a solid BoP, is once again presented as one of the favorites for this race.
With the necessary race strategy, the Porsche drivers will be able to attempt to achieve a good result, maintaining the optimism that the numbers could translate into victories. On the other hand, Cadillac faces a considerable challenge, assigned with one of the highest power-to-weight ratios in low-speed sections.
Regarding the Aston Martin, this weekend will be difficult due to a less favorable relative BoP, and the team will have to wait for the season finale to have a podium option with the Valkyrie.
