Every 2026 F1 retirement, counted: Aston Martin has failed to finish more than half its races
66 cars have failed to finish the first fourteen Grands Prix of 2026. Aston Martin account for 15 of them, more than half their entries, and Lance Stroll has not finished ten races. Every retirement counted by team, engine and driver.
Lance Stroll has started fourteen Grands Prix in 2026 and been classified at the finish of four.
His Aston Martin team mate Fernando Alonso has failed to finish five. Between them that is 15 of the team's 28 race entries, 54%. The team's best known problem is vibration from Honda's new power unit: it appeared in pre-season testing, has been blamed for damaging other components, and left both drivers worried about nerve damage in their hands. At the other end of the grid, Alpine have failed to finish once all season.
Across the first fourteen rounds, 66 cars did not finish
, one in every five entries. Here is every one of them, counted by team, by engine and by driver. Some of the most revealing moments are on the radio: every message from the most recent race, in Madrid, where Lewis Hamilton, Lance Stroll, Sergio Perez and Carlos Sainz all retired, is in our
First fourteen Grands Prix of 2026. Counts retirements, non-starts, and cars running at the end but too far behind to be classified.
The pattern is not simply that the slower teams break down. Mercedes, the fastest car of the year, have failed to finish three times, and Alpine once. McLaren, with a car quick enough to win twice, have failed to finish six times, including both cars not starting in China.

Every 2026 entry grouped by the power unit in the car.
Honda's figure stands on its own. The Ferrari figure is lifted by Cadillac, a brand new team in its first season: without Cadillac, Ferrari-powered cars have failed to finish 9 of 56 entries, 16%, level with Mercedes. Red Bull's first in-house power unit, built with Ford, has the best record of the five.
These counts include crashes as well as failures, because the timing data records that a car retired, not why. The engine-maker comparison is therefore a guide, not a verdict on any one power unit.

First fourteen Grands Prix of 2026.
The races that broke the most cars
Barcelona, eight. Including Kimi Antonelli, who stopped with an apparent power unit problem four laps from the end while running second, and Charles Leclerc with a hydraulic failure.
China, seven. Four of them never started: both McLarens with separate electrical problems on their power units, plus Gabriel Bortoleto and Alexander Albon.
Monaco, seven. Including Max Verstappen, whose engine died as he dropped the clutch at the start:
"What should I do?" He fell from second to last and retired after one lap. Lando Norris retired with a power unit failure and Leclerc with brakes that stopped working after a safety car restart.
When it happened to the front runners
Every driver in the top seven has lost at least one race to their car, and the radio usually tells you before the broadcast does. Lewis Hamilton in Madrid, a few laps in:
Lewis HamiltonFerrari · Spanish Grand Prix 2026 · Race · 15:12:56 local
Each of these is explained race by race in the driver reviews: Antonelli (Barcelona, power unit), Russell (Canada, a battery failure from the lead), Hamilton (Madrid, brakes), Norris (China, Canada, Monaco), Leclerc (Monaco, Barcelona), Verstappen (China, Monaco) and Piastri (China, Hungary). The whole table is in the 2026 standings.
How we count
A non-finish here means the car was not classified at the end of the race. That covers retirements, cars that did not start, and cars still running but so far behind that they were not classified: Stroll in Australia completed 43 of 58 laps and was not classified.
A few retirements are still classified, because the car had completed enough of the race. Antonelli in Barcelona retired four laps from the end and is classified sixteenth. We count those as non-finishes too, because the car did not see the chequered flag.
Crashes and failures are counted together. The timing data records a retirement, not its cause. Where we give a cause, it comes from the team or driver, and the source is listed below.
Frequently asked questions
Which F1 team has the most retirements in 2026?
Aston Martin, with 15 non-finishes from 28 entries in the first fourteen races, 54%. Cadillac are next with 11.
Why is Aston Martin so unreliable in 2026?
Vibrations from Honda's new power unit, first seen in pre-season testing, have been blamed for damaging other components in the car. Both drivers have also spoken about the vibrations affecting their hands.
Which F1 engine is the most reliable in 2026?
Red Bull Ford, whose cars have failed to finish 14% of entries, followed by Mercedes at 16%. Crashes are included in those counts, so they are a guide rather than a pure reliability measure.
How many cars have retired in F1 in 2026?
66 non-finishes across the first fourteen Grands Prix, out of 308 entries, about one in five.

Know why before the broadcast does
A car stopping is on screen. Why it stopped is on the radio first, and in the stewards' and technical documents after.
The Formula Dream app plays live driver radio as it is broadcast, transcript beside the audio, and collects every FIA document of the weekend as it is published, including the power unit and gearbox changes that turn a failure into a grid penalty at the next race. There is also a live timing Dashboard, currently in beta.

Nineteen Chinese Grands Prix have been held in Shanghai since 2004. Lewis Hamilton won six, pole won twelve, and in 2026 Kimi Antonelli took the first win of his career there, at 19, with Hamilton on the podium for Ferrari for the first time. Every winner, grid slot and safety car, measured.
