Ferrari arrived at the Barcelona Catalunia circuit two weeks ago with a list of eight new parts for Lewis Hamilton’s car, all filed legally with the FIA. Hamilton then won his first race for the team by almost 20 seconds, yet the part that may have mattered most was never on that official list. While the paddock studied the new floor, Ferrari quietly bolted on something else, a hidden choice that offers a clue to how Hamilton can claw back a 41-point gap in the title race. The question of how a team that did not win a single race in 2025 suddenly built the fastest car on a Sunday afternoon is answered by the package sitting in the body of the SF26.
Ferrari’s official filing to the FIA covered eight parts on the SF26, including a new front wing with a new foot plate, a reworked set of veins, and a small wing added to the end plate. The nose was new with a raised lower surface, and the floor work was split into three separate changes: the floor body, the floor edge, and the floorboard. The diffuser was reshaped with a redrawn side cutout and a new angle on the diffuser winglet, while a puffed out side pod shoulder fed a tighter coke line at the back of the car. The floor was the heart of the upgrade, as Ferrari reshaped the keel, redrew the front edge of the floor, and reworked the small upright pieces called claws that guide the air along the floor’s edge.
Against those steps, other teams brought smaller updates to the same race, with McLaren showing up with a single new front wing end plate, Mercedes adding a pair of small winglets to the rear wing, and Red Bull changing the shape of its front wing. One top expert noted that the upgrade covered most of the car from the front wing to the diffuser and nothing was left untouched. Toto Wolf of Mercedes summed up the package in one word, calling it a monster. The Barcelona Catalunia circuit is known as an open-air wind tunnel, with fast corners, slow corners, and everything in between, punishing any car that is weak in the air.
Hamilton put the upgraded Ferrari within 6 hundredths of a second of pole position in qualifying, with George Russell taking top spot for Mercedes and Kimmy Antonelli lining up third. The other Ferrari struggled, as Charles Leclerc crashed in the last part of qualifying and could start no higher than 10th. The part that was never on the FIA list was new wheel rims, not flagged as a body upgrade because they are not bodywork at all, but instead pull heat out of the tires from the inside. In 2026, holding down tire heat is a deep hidden battle, as a cooler tire holds its grip longer and fades later in a stint, allowing a driver to keep pushing while rivals ease off.
Ferrari kept its rear rims hidden from view all weekend, shielding them from cameras and rival photographers. The listed floor gave the car more downforce, while the hidden rims gave the tires a longer life, a mix that set up everything that happened on race day. Hamilton started on the soft tire and went with a bold three-stop plan, while most of the field tried to make the race work on two stops. His first stop came on lap 12, a classic undercut to steal track position by bolting on fresh rubber while his rivals stayed out on old tires.
On lap 41, Fernando Alonso pulled his struggling Aston Martin off the circuit before turn 9, and the race went to a virtual safety car. Ferrari called Hamilton in without a pause, and he took his last set of tires, losing almost nothing to the cars around him. His race engineer, Carlos Santi, came onto the radio with the call of the day, saying, “This is our race. Give everything these seven laps.” After that last stop, Hamilton was running tires five laps fresher than Russell and four laps fresher than Antonelli, with a post-race study putting his edge at about three-quarters of a second per lap.
Hamilton crossed the line 19 and a half seconds clear of Russell, the biggest winning gap anyone had managed all season, marking his first win for Ferrari, his 106th in Formula 1, and his first win in 686 days. At 41 years old, he became the oldest man to win a Grand Prix since 1970 and the first driver in history to win races in his 20s, his 30s, and his 40s. The podium behind him was fully British for the first time since 1968. The car that won Barcelona is the first one drawn almost fully under new leadership, with Fred Vasseur having taken over Ferrari at the start of 2023 and hiring a new tech chief away from Mercedes.
Mercedes did not lose this race purely on pace, as they lost it on breakdowns. With four laps to go, Antonelli, the title leader, suddenly slowed and stopped at the exit of turn five after suffering a power shutdown, the second time in three races that a Mercedes had failed in almost exactly the same way. Russell had already dropped out of the lead of the race in Canada with a similar fault. The team’s own tech chief admitted the failures trace back to the same broad part of the battery and called the whole thing very painful in public. In a single afternoon, the title lead Antonelli was carrying fell from 66 points down to 41.
Ferrari is set to bring an engine step as soon as the very next round in Austria with a new fuel and an updated engine, the first of two engine gains the team is allowed this season. A second bigger engine step is set for later in the year around the Italian Grand Prix. Power has been the one area where this Ferrari still trails its rivals, and closing that gap turns a strong car into a complete one. Race study from the paddock put it plainly, stating that with this many races still left on the calendar and a Ferrari now looking this strong, the gap between Antonelli and Hamilton does not look too big to close.
The team picture tells the same story from a different angle, as Mercedes still leads that title comfortably, but Ferrari is now the team with the push, the upgrades, and the rival with the breakdown problem. The 41-point gap is less than two race wins across 15 races still left, and Hamilton does not need to be perfect, he needs the Ferrari to keep finishing ahead of the Mercedes. The next test comes right away in Austria, a power circuit with long straights and short sharp corners, a fully different challenge from the air puzzle of Barcelona. The car that won in Barcelona is the base Ferrari spent three years building, and it has 15 races left to prove what it can really do.
