The car at a glance

The MAC-26 is the first car from Cadillac, Formula 1's new eleventh team. For now Cadillac buys its engine from Ferrari – a customer engine. The FIA has approved a General Motors power unit from 2029.

After 19 races the team has yet to score a point (11th in the constructors’ standings). Its best race result so far is 13th. The car fell back as the season went on: in qualifying the better of its two cars was 19.0 on average in the first 7 races, and 20.6 in the last 5 races. In total the team declared 39 new parts for more speed to the FIA; the biggest package came at the Austrian Grand Prix (10 parts).

Cadillac is the only brand-new team on the grid. The team revealed its race livery in a commercial during the Super Bowl.

Specific to the Cadillac MAC-26
Component	Value
Engine	Ferrari 067/6The engine comes from Ferrari; the team does not build it itself.
Gearbox	Ferrari inner parts, Cadillac casing8 forward gears and 1 reverse; the driver shifts with paddles on the steering wheel.
Fuel partner	ShellAll teams use sustainable fuel in 2026; the partner blends it to FIA specifications.

The same for all cars (rules)
Component	Value
Combustion engine	1.6-litre turbo V61600 cc displacement, 6 cylinders in a V (90 degrees), one turbocharger.
Maximum engine speed	15,000 rpmThe most revolutions per minute the engine’s crankshaft may turn.
Combustion engine power	around 400 kW (about 540 hp)Clearly less than up to 2025 – the electric motor delivers much more instead.
Electric motor (MGU-K)	up to 350 kW (about 470 hp)Recovers energy under braking and adds power when accelerating. Its power is reduced on very fast straights.
Total power	just over 1000 hpOnly as long as the battery supplies enough energy.
MGU-H	no longer usedThe second generator on the turbocharger was dropped for 2026.
Fuel	100% sustainableMade for example from captured CO₂, waste or non-food biomass.
Gearbox	8 forward gears, 1 reverseSequential and semi-automatic: the driver selects each gear, the shift itself is hydraulic.
Chassis	Carbon-fibre monocoqueThe rigid safety cell the driver sits in.
Minimum weight	724 kg plus tyres (768 kg)With driver, without fuel; 726 kg plus tyres in qualifying. Around 30 kg less than in 2025.
Width	at most 1900 mm10 cm narrower than up to 2025.
Wheelbase	at most 3400 mmDistance between the front and rear axles, 20 cm shorter than up to 2025.
Aerodynamics	active wings, no more DRSFront and rear wings go flat on straights (Straight Mode, less drag) and steep for corners (Corner Mode, more downforce); early announcements called this X- and Z-mode.
Tyres	Pirelli, 18 inchControl tyres: every team uses the same Pirelli tyres.

2026 team comparison

Calculated from official timing data, average over 19 race weekends (as of Mexico City Grand Prix 2026).

Relatively best

Top speed: 10th of 11 – 320.7 km/h at the speed trap on average.

Weaknesses

Speed over one lap (qualifying): 11th of 11 – on average 3.97 % (about 3.34 s) off the fastest lap.
Pace loss on one set of tyres: 11th of 11 – the lap time gets 0.022 s slower per lap on a set of tyres on average.

1st = best value of the eleven teams. The explanation is shown below each name.

2026 team comparison: Cadillac MAC-26
Value	Cadillac MAC-26	Rank
Top speedHighest speed measured at the speed trap on the straight, averaged over all race weekends. Higher is better.	320.7 km/h	10 of 11
Speed over one lap (qualifying)Gap from the team’s best qualifying lap to the fastest lap of the day, on average. 0 means it set the fastest lap itself. Lower is better.	+3.97 % (approx. 3.34 s)	11 of 11
Sector 1 (qualifying)Every track is split into three sectors. Gap to the best time in the first sector. Lower is better.	+3.70 %	10 of 11
Sector 2 (qualifying)Gap to the best time in the middle sector. Lower is better.	+4.33 %	11 of 11
Sector 3 (qualifying)Gap to the best time in the final sector. Lower is better.	+4.00 %	11 of 11
Race paceTypical lap time in the race (without the start, pit stops and safety car periods), gap to the fastest team. Lower is better.	+4.03 % (approx. 3.64 s)	10 of 11
Laps per set of tyresHow many laps a car ran on one set of tyres in the race, on average. More usually means the tyres last longer.	16.1 laps	10 of 11
Pace loss on one set of tyresHow the lap time changes from lap to lap on the same set of tyres. Wearing tyres make the car slower, the emptying fuel tank makes it faster. Lower is better; a minus means the car even got faster over the run.	+0.022 s per lap	11 of 11
Pit stop timeHow much longer a car spent in the pit lane per stop than the fastest team (driving through plus the tyre change). Lower is better.	+2.78 s	11 of 11

Upgrades during the season

As declared by the teams to the FIA before each Grand Prix (39 new or changed parts).

Reason given by the team: “performance” means the part is meant to make the car faster. “Circuit-specific” means it is adapted to one particular track, for example more cooling in the heat or less drag for long straights. “Reliability” means it is meant to prevent failures.
