Mercedes-Led Field Arrives at Miami Amid ‘New Championship’ Talk as Teams Unveil Major Upgrades
Formula 1 returns to action at the Miami Grand Prix on May 1–3 following a five-week enforced break caused by the cancellation of the Bahrain and Saudi Arabian Grands Prix due to the Middle East conflict. Mercedes arrive as clear championship leaders, having swept all three opening races through George Russell and Kimi Antonelli, but Ferrari team principal Fred Vasseur declared a “new championship” is beginning, with every team bringing substantial car upgrades after the extended factory window. The Miami International Autodrome hosts rounds four and five of the season, with a Sprint format adding extra pressure across the shortened three-day weekend.

FIA Confirms Power Unit Rule Changes for Miami to Tame Super-Clipping After Bearman Crash
The FIA confirmed sweeping changes to Formula 1’s 2026 power unit regulations ahead of the Miami Grand Prix, directly addressing the dangerous closing speed differentials that contributed to Oliver Bearman’s 50G crash at Suzuka. Qualifying energy recovery is reduced from 8 megajoules to 7, limiting available electrical deployment during laps. In race conditions, the MGU-K is capped at 250 kilowatts outside designated acceleration zones, while maximum boost mode power is restricted to 350 kilowatts. Additionally, from Miami onwards the FIA introduces a low-power start detection system to prevent hazardous acceleration gaps off the line. A World Motor Sport Council e-vote will formally ratify the changes.

McLaren Brings Entirely Redesigned MCL40 to Miami in Bid to Challenge Mercedes
McLaren will bring what team principal Andrea Stella describes as an entirely new version of its MCL40 to the Miami Grand Prix, representing the most comprehensive single-event aerodynamic overhaul from any team this season. The reigning world champions have struggled to match Mercedes across the opening three rounds, with Oscar Piastri their best-placed driver in sixth on 21 points. Stella confirmed the update package replaces most aerodynamic surfaces and potentially some suspension geometry, all targeting more efficient downforce generation — the area where Mercedes holds its performance advantage. He stressed that McLaren expects rivals to bring similarly large upgrade packages, cautioning against assuming a straightforward shift in the pecking order.

Ferrari Tests Revised Floor and New Battery Software at Monza Ahead of Miami Upgrade Push
Ferrari conducted a 200km filming day at Monza on April 22 to validate a substantial three-part upgrade package destined for the Miami Grand Prix. The overhaul centres on a revised floor designed to increase aerodynamic downforce, a reworked battery charge management software to reduce the effects of super-clipping on straights, and cooling system refinements. Lewis Hamilton and Charles Leclerc are expected to benefit most from the software changes, which Ferrari believe will allow them to maintain better pace on Miami’s long straights where the SF-26 has suffered. Ferrari trail Mercedes by 45 points in the Constructors’ Championship and need a strong result to remain within striking distance.
Antonelli Carries Nine-Point Lead Into Miami as Youngest F1 Championship Leader in History
Kimi Antonelli carries a nine-point championship lead into the Miami Grand Prix at just 19 years old, having become the youngest driver in Formula 1 history to lead the Drivers’ Championship following his victory at Suzuka. The Italian claimed two of the season’s first three wins, with Russell taking the other in Australia. Antonelli leads with 72 points to Russell’s 63, Ferrari’s Charles Leclerc third on 49, and Lewis Hamilton fourth on 41. Despite his dominant form, Antonelli has downplayed title ambitions, saying it is “still too early to think about the championship.” He acknowledged the five-week break disrupted his competitive rhythm heading into Miami.

ADUO Engine Framework Divides Paddock as FIA Nears Ruling on Eligible Manufacturers
The FIA’s ADUO framework — granting extra development to power unit manufacturers judged two to four percent behind the class leader — remains a source of tension heading into Miami. Mercedes boss Toto Wolff said he would be “surprised and disappointed” if an ADUO ruling influences the title fight, suggesting only Honda appears in sufficient deficit to qualify. Ferrari’s Fred Vasseur claims their power unit disadvantage could be worth up to 0.8 seconds per lap. Reports during the April break alleged Mercedes had been managing engine deployment strategically to keep rivals below the ADUO eligibility threshold — an allegation the Brackley team denied ahead of Miami.

FIA Grants Extended 90-Minute Practice Session at Miami After Regulation Reset and Race Cancellations
The FIA confirmed that Free Practice 1 at the Miami Grand Prix will be extended from 60 to 90 minutes, granting teams additional time to adapt to the new power unit regulations taking effect this weekend. Three factors drove the decision: the five-week gap created by the Bahrain and Saudi cancellations, the need to evaluate freshly ratified energy management rule changes, and Miami’s Sprint format which limits teams to a single practice session before Saturday’s Sprint Qualifying. FP1 is scheduled from 12:00 to 13:30 local time on Friday, May 1. The FIA said the extension reflects the exceptional regulatory circumstances surrounding the fourth round of the 2026 season.

Mercedes Drivers to Race in Purple Suits and Pink Helmets at Miami Grand Prix
Mercedes will debut a special purple appearance for the Miami Grand Prix, with George Russell and Kimi Antonelli wearing bright purple race suits under their partnership with sportswear brand Nu. Both drivers will also sport pink-themed helmets for the Florida race weekend, a marked departure from their usual black, white and turquoise kit. The W17 car’s livery itself remains unchanged. Mercedes and Nu formalised their collaboration at the start of the 2026 season. The visual change adds renewed energy to F1’s return to action at the Miami International Autodrome following the five-week enforced April break caused by the cancellation of the Bahrain and Saudi Arabian Grands Prix.

Pirelli Selects Softest Compounds for Miami Sprint Weekend Amid High-Temperature Forecast
Pirelli has selected its softest three compounds — C3, C4 and C5 — for the Miami Grand Prix, suited to the smooth asphalt and expected ambient temperatures around 28 degrees Celsius. The tyre supplier anticipates a predominantly one-stop race for Sunday, though large upgrade packages from multiple teams could alter pace differentials and force reactive strategy calls. Five weeks without competitive running means teams carry limited real-world degradation data into Friday’s extended FP1, making the 90-minute practice window before Saturday’s Sprint Qualifying especially valuable. Pirelli expects the softer compounds to behave consistently given the forecast dry and warm conditions throughout the Miami weekend.
