IMSA Pre-Season Test at Daytona: Technical Updates and Lap Times
The IMSA SportsCar Championship commenced its 2026 campaign with a pre-season test at Daytona International Speedway, featuring significant updates from all four LMDh manufacturers: Porsche, BMW, Cadillac, and Acura.
Cadillac’s Notable Changes
Cadillac unveiled the most substantial revisions, introducing a completely redesigned rear wing element on the V-Series.R, now mounted lower, alongside a new splitter devoid of diveplanes and an upgraded Brembo braking system. Utilizing Evo Jokers two and three, Cadillac is strategically optimizing its performance, with two additional tokens available until 2027, and one styling-specific joker for homologation through 2029.
BMW’s Aerodynamic Enhancements
The BMW M Hybrid V8 emerged with a revamped bodywork configuration, incorporating smaller kidney grilles and redesigned internal channels. Approximately 50% of the bodywork has been updated to enhance drivability, although the specific Evo Jokers exploited remain unconfirmed.
Porsche’s Subtle Adjustments
Porsche’s updates primarily affected the two factory-run Penske entries, featuring a new front splitter, revised diffuser, and suspension improvements. The privateer JDC-Miller Porsche will upgrade to align with these changes before the upcoming Roar before the 24 test.
