Cadillac's first Formula 1 car. A new chassis, a new aerodynamic philosophy, and a Ferrari power unit for the opening three seasons — before GM's own PU arrives in 2029.
F1's biggest regulation reset since 2014. Smaller, lighter cars; a 50/50 split between combustion and hybrid power; fully sustainable fuel; active aerodynamics. Every car on the grid is brand-new — and Cadillac is one of two completely new operations entering the championship.

Cadillac's PU strategy is a three-year bridge. Ferrari supplies the 2026-spec power unit for seasons 2026, 2027, and 2028 — long enough for GM to bring its own purpose-built F1 PU online for 2029. It's the same playbook McLaren used with Mercedes in the early hybrid era, with one difference: GM is paying to be its own customer and supplier.
Power Unit Roadmap
2026 is F1's biggest reg reset in over a decade. Four headline changes drive the whole field's rebuild — and dictate the MAC-26's design priorities.
The MGU-K's electric output roughly triples vs. 2025. Combustion still makes around 540 kW, but the battery now contributes nearly the same — making efficient deployment as important as raw power.
Front and rear wings now reconfigure between low-drag "straight-line" mode and high-downforce "cornering" mode. Replaces DRS, and the override is driver-managed everywhere — not zone-limited.
Minimum weight drops to 768 kg (from 798), wheelbase reduces, and overall width tightens. Smaller cars are nimbler in slow corners — and the weight cut hurts heavier drivers less than before.
Drop-in sustainable fuel — synthesized from biological waste or atmospheric CO₂ — replaces 2025's E10 blend. Same energy density, very different supply chain.
Cadillac F1 is the first team to operate as a fully transatlantic build from day one. Chassis design in Silverstone, race operations and final assembly in Charlotte, GM technology integration in Warren.
Northants, UK
Chassis design, aerodynamics, wind tunnel work. Inherits the technical core of the former Andretti Cadillac F1 operation that established here in 2024.
Concord, NC, USA
Race-team HQ. Logistics, race operations, paddock support, and final assembly for the Americas-leg of the calendar. The hub closest to GM's NASCAR & IndyCar operations.
Michigan, USA
GM Global Technical Center. Power unit development for the 2029+ in-house PU program; corporate technology transfer; battery and software integration with the broader GM EV portfolio.
A blend of F1 veterans (Budkowski, Symonds, Chester) and senior GM executives (Reuss, Towriss). Most of these have an interview on The Garage page if you want to hear them speak directly.
Team Principal
Appointed 12 August 2026, replacing Graeme Lowdon mid-season. Two decades in F1 across Ferrari, McLaren and the FIA — where he ran the technical department — then executive director at Renault/Alpine. Brought in to take the team from its build phase into chasing performance.
CEO · TWG Motorsports
Chief executive of the holding company financing Cadillac F1's parent organization. The dealmaker who closed the FIA entry.
President · General Motors
GM's senior-most racing advocate. Drove the F1 entry from inside GM and oversees the 2029 in-house PU program.
Chief Technical Officer (Advisory)
Williams & Benetton/Renault championship-era engineer. Joined the project from the FIA, where he wrote the 2022 regulations.
Technical Director
Former Renault & Lotus F1 technical chief. Leads chassis engineering out of Silverstone.
Pérez and Bottas race the MAC-26, but they aren't the only two who drive it. Cadillac runs a test driver on Friday mornings, which is both a development tool and an audition.
Test Driver
Signed as Cadillac's test driver for 2026 and scheduled for four FP1 sessions, standing in for Pérez or Bottas on a Friday morning. The first came at Barcelona in June; Monza was another — an early stoppage there brought the team a fine. Alongside the F1 role he is a rookie in Formula 2 with Hitech, chasing the superlicence points an F1 seat would need. A former IndyCar front-runner, he is the closest thing this team has to a homegrown American prospect.
