Cadillac to debut first major upgrade package at home race in Miami

Cadillac will run its first major upgrade package at the Miami Grand Prix, its debut home race. A five‑week development pause after early‑season cancellations gave the American team time to revamp its MAC‑26 chassis, and they hope the new parts will lift the car up the grid.

Currently sitting 10th in the constructors’ standings with a best finish of 13th in China, Cadillac needs a performance boost to move out of the back‑marker zone.

Why it matters:

• Floor redesign targets down‑force efficiency under 2024 regulations, where small gains improve corner speed.
• Weight‑saving across the chassis could shave tenths of a second per lap while easing tyre wear.
• Delivering a full spares inventory and coordinated manufacturing shows Cadillac’s growing operational maturity.

The details:

• Floor – new geometry to boost down‑force within floor height limits.
• Front wing – updated endplates and leading‑edge shape for cleaner airflow.
• Rear‑brake drums – lighter alloy reduces unsprung mass and aids cooling.
• Weight‑saving – material swaps and component consolidation cut overall mass.
• Sprint‑weekend – limited practice means data must be gathered fast; the longer FP1 offers a narrow testing window.

What's next:

• Validate the upgrades in race conditions, a milestone for a team in only its fourth Grand Prix.
• If the changes deliver measurable lap‑time gains, Cadillac could climb out of the back‑marker pack.
• Performance data will shape the development plan for the upcoming European swing.
