If the final day of the 2026 Formula 1 shakedown in Barcelona proved anything, it’s that the new era of the sport is not just coming—it has arrived with a roar, a few spins, and one glaringly empty garage. As the sun set on the Circuit de Barcelona-Catalunya, the paddock was buzzing not just with the whine of the new power units, but with whispers of radical aerodynamic gambles and shocking reliability woes.

The “shakedown”—traditionally a quiet affair meant simply to check if the wheels stay on and the engine fires up—morphed into a headline-grabbing spectacle this week. From Adrian Newey’s audacious designs to a catastrophic failure for one of the sport’s most historic names, here is the full breakdown of a week that may have just defined the early narrative of the 2026 season.

The “Batmobile” Has Landed

Let’s start with the car that had every photographer in the pit lane scrambling for a better angle: the Aston Martin.

While they were late to the party, not hitting the track until late in the week, the wait was arguably worth it. Under the guidance of the legendary Adrian Newey, Aston Martin has unveiled a machine that looks less like a traditional F1 car and more like something Bruce Wayne would drive through Gotham. The AMR26 boasts the most aggressive aero platform on the grid, featuring a rear suspension setup that effectively doubles as a beam wing.

It is a design that screams “high risk, high reward.” On Friday, Fernando Alonso took the wheel, and while the team ran the engine conservatively to test its limits, the visual statement was made. A candid shot of Alonso and Newey deep in conversation trackside has already become the defining image of the test—a master designer and a master driver plotting a coup. The car looks menacing, futuristic, and fast. But as always with Newey’s creations, the question remains: is it too complex for its own good?

Mercedes: The Mileage Kings

If Aston Martin won the beauty contest, Mercedes won the war of attrition.

Labeled by some as the “overhyped” favorites coming into the test, the Silver Arrows silenced doubters by simply refusing to stop running. They were the only team to break the 500-lap barrier, a staggering feat of reliability for a brand-new regulation cycle. While their customer team, McLaren, suffered hiccups on day four that limited their running, the factory Mercedes unit looked bulletproof.

It wasn’t just about going round and round, though. The W17 features several visible innovations that hint at a deep understanding of the new rules. They may not have the “Batmobile” shock factor of the Aston, but in the world of F1 testing, boring reliability often translates to championships. They maximized every minute of the Barcelona track time, gathering a mountain of data that could give them a crucial head start when the real racing begins.

The Prancing Horse Gallops Under the Radar

While the British teams grabbed the headlines, Ferrari quietly went about their business—and that should terrify their rivals.

Except for a wet session on day two, the Scuderia ran virtually non-stop. The reliability of the new Ferrari power unit appears to be rock-solid, a sentiment echoed by their customer team, Haas. In fact, Haas drivers Oliver Bearman and Esteban Ocon were frequently seen topping the timing sheets in their respective sessions.

Lewis Hamilton, getting to grips with his new Scarlet machinery, had a few spins—a clear sign that these 2026 cars are beasts that need taming. Drivers like Liam Lawson and Charles Leclerc have openly discussed how the new cockpit dynamics allow for a much significant difference in driver input. The cars are harder to drive, more physical, and more punishing of mistakes. For Ferrari, however, the base is there. They didn’t chase glory runs, but they looked ominous, efficient, and ready.

The Williams Nightmare

You cannot talk about who was there without addressing who wasn’t. Williams Racing missed the entire shakedown.

In a sport where mileage is gold, missing a full preseason test is akin to starting a marathon with your shoelaces tied together. While other teams were refining setups and testing engine limits, the Williams garage remained shut. This is a disastrous start for a team that has been desperate to climb back up the order. Every lap Mercedes and Ferrari turned was a lap of data Williams lost. The repercussions of this delay could haunt them well into the mid-season.

Audi’s Reality Check and Alpine’s Hope

Newcomers Audi had a mixed debut. They didn’t “pull a Williams”—thankfully—but they certainly didn’t set the world on fire. Their running was limited, and they struggled to extract the maximum from the session. However, simply getting the R26 on track and giving their drivers a taste of the new power unit is a small victory for the manufacturer. They are on the back foot, but they are moving.

On the flip side, Alpine looks like a team reborn. After a dismal 2025, the French outfit has seemingly poured every ounce of their resources into the 2026 regulations. Their aero package is advanced, arguably second only to Aston Martin in creativity. With ambitious targets of points in every race, Alpine is the dark horse to watch. They, along with a surprisingly solid Red Bull Racing (who overcame an Isaac Hadjar crash to log solid miles), prove that the midfield battle is going to be a bloodbath.

The Verdict

We must be careful not to read too much into lap times during a shakedown. Fuel loads were unknown, engine modes were turned down, and tires were a mystery. But we can judge intent, reliability, and design philosophy.

Mercedes is ready for war. Aston Martin is betting on genius. Ferrari is lurking in the shadows. And Williams is already fighting for survival.

The 2026 cars look incredible—sleek, aggressive, and draped in carbon black. But more importantly, they look difficult to drive. The era of the “easy” F1 car is over. As the circus packs up and heads to Bahrain for the next round of testing, one thing is clear: the status quo has been shattered.

Buckle up. 2026 is going to be a wild ride.
