F1 2026 DNFs: Every Retirement by Team, Counted | Formula Dream

Every 2026 F1 retirement, counted: Aston Martin has had more than half its cars unclassified
79 cars have been left unclassified in the first nineteen Grands Prix of 2026. Aston Martin account for 20 of them, more than half their entries, and Lance Stroll for 13. Every one counted by team, engine and driver.
Lance Stroll has been entered in nineteen Grands Prix in 2026 and been classified in six.
His Aston Martin team mate Fernando Alonso has been left unclassified seven times. Between them that is 20 of the team's 38 race entries, 53%. In Mexico City both cars were out inside the first seven laps. 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, Mercedes have had two cars unclassified all season, and Ferrari and Racing Bulls three each.
Across the first nineteen rounds, 79 cars were not classified, almost one in every five entries. Here is every one of them, counted by team, by engine and by driver, from the official classification. Some of the most revealing moments are on the radio: every message from the most recent race, in Mexico City, is in our Mexico City Grand Prix 2026 race radio archive.

First nineteen Grands Prix of 2026, from formula1.com's classifications. 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 had two cars unclassified. McLaren, with a car quick enough to win twice, have had seven, including both cars not starting in China. Alpine had one in the first fourteen races, the best record on the grid, then three in three races, two of them in one collision between its own drivers in Baku.

Every 2026 Grand Prix entry of rounds 1 to 19, 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 been unclassified in 9 of 76 entries, 12%, close to Red Bull Ford. Red Bull's first in-house power unit, built with Ford, has the best record of the five, and has now won three races as well.
These counts include crashes as well as failures, because the classification records that a car stopped, not why. The engine-maker comparison is therefore a guide, not a verdict on any one power unit.

First nineteen Grands Prix of 2026.
The races that broke the most cars
China, seven. Four of them never started: both McLarens with separate electrical problems on their power units, plus Gabriel Bortoleto and Alexander Albon.
Australia, Canada, Monaco and Baku, six each. At Monaco that included 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 Charles Leclerc with brakes that stopped working after a safety car restart. In Baku, both Alpines and Norris went out in one accident at turn 1, and both Aston Martins retired.
Mexico City, five. Both Aston Martins were out inside seven laps, Valtteri Bottas's Cadillac lost its front left suspension at turn 1 and brought out a red flag, Arvid Lindblad crashed after contact with Oscar Piastri, and Oliver Bearman retired after contact with Nico Hulkenberg. The race is in our Mexico City GP 2026 race report.
Barcelona, five unclassified and three more retirements. Kimi Antonelli stopped with an apparent power unit problem four laps from the end while running second, Leclerc with a hydraulic failure, and Oliver Bearman also stopped. All three had covered enough laps to be classified.
When it happened to the front runners
Every driver in the top seven has lost at least one race to their car or an accident, and the radio usually tells you before the broadcast does. Lewis Hamilton in Madrid, a few laps in:
"I don't have brakes, guys." And Lando Norris in Canada, as his gearbox went:
Each of these is explained race by race in the driver reviews: Antonelli (Barcelona, power unit, classified), Russell (Canada, a battery failure from the lead; Spa; Sepang, power unit, classified), Hamilton (Madrid, brakes), Norris (China, Canada, Monaco, Baku), Leclerc (Monaco, Barcelona, Monza), Verstappen (China, Monaco, Silverstone, Zandvoort) and Piastri (Australia and China, both before the start, and 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, exactly as formula1.com's classification shows it. 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.
Nine retirements are still classified and are not in these counts, because the car had completed enough of the race: Sainz at Monaco, Leclerc, Antonelli and Bearman in Barcelona, Verstappen at Silverstone, Albon at Zandvoort and in Singapore, Bottas in Baku and Russell at Sepang. This page counted them as non-finishes until 18 October; it now follows the classification, which is the same rule every season review on this site uses.
Crashes and failures are counted together. The classification records that a car stopped, not why. 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 20 cars unclassified from 38 entries in the first nineteen races, 53%. Cadillac are next with 14.
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 been unclassified in 11% of entries, followed by Mercedes at 14%. 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?
79 cars unclassified across the first nineteen Grands Prix, out of 418 entries, almost one in five. Another nine retired late enough to be classified.

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.

Every Miami Grand Prix winner, measured: five races, and pole has won only one of them
Five Miami Grands Prix have been held since 2022, and only one was won from pole: Kimi Antonelli's in 2026. Max Verstappen won from ninth in 2023, and Lando Norris took his first win there in 2024. Every winner, grid slot and safety car, measured.
