Power to Weight

Aston Martin keeps the best power/weight ever! BMW would be at the previous best case, if it wasn’t was Aston Martin. Ups and downs for the rest. The 2026 Porsche is again brought a little closer to the pack.

All GTP era BoPs. c* indicates IMSA corrected the values pre-event.

Weight

For Porsche and Cadillac there are changes to weight.

Power

Recent power changes for BMW are reversed. the big change is a reduction for last year’s Porsche which is combined with a weight increase.

High Speed Power

Some of that Porsche 2025 power loss is combined with a gain in power at high speed. BMW gains power low down and high up.

High Speed power adjustment introduced from 2024 Daytona BoP test. High Speed power >240kph, except Laguna Seca, Detroit and Long beach from 2025 Laguna Seca onwards (>200kph)

Replenishment Rate

A full 100% energy stop is still 40 seconds.
