Let’s take a look at how many laps and kilometres each team and power unit manufacturer completed over the five days of testing in Barcelona.

The Barcelona tests have just wrapped up after five days of running which, while offering little in terms of outright performance indications, delivered plenty of valuable feedback on mileage — with the 2026 cars already appearing to be in a solid place from a reliability standpoint.

Mercedes topped the mileage charts across the five days of running, racking up a total of 500 laps. Ferrari followed with 437 laps, while Haas also enjoyed a productive test with 391 laps completed.

Alpine logged a solid 349 laps over the week, with Racing Bulls and Red Bull close behind on 318 and 303 respectively. McLaren completed 288 laps in total, while Audi accumulated 243 across the test. Cadillac reached 164 laps, Aston Martin’s running was limited to just 65, and Williams failed to register any mileage in Barcelona.

From a power unit perspective, Mercedes clearly set the benchmark, with its three teams combining for an impressive 1,137 laps over the five days. Ferrari-powered cars were next on 992 laps, followed by Red Bull–Ford with a combined total of 621.

Audi, running a single-car programme, completed 243 laps, while Honda endured a difficult week, managing just 65 laps across the entire test.

Below is a full breakdown of the running completed in Barcelona, covering both the teams and the power unit manufacturers.
