FIA Plans Energy Management Fix Before Miami as Domenicali Backs Rule Tweaks
Formula 1 CEO Stefano Domenicali has backed targeted changes to the 2026 technical regulations, saying he hopes the FIA will announce qualifying and safety adjustments before the Miami Grand Prix on May 1. The primary focus is energy management — specifically, preventing the dangerous speed differentials that occur when cars exhaust their electrical energy on straights and decelerate abruptly in braking zones. Domenicali acknowledged Max Verstappen’s criticism of the new rules but urged the four-time champion to respect the weight of his words. The FIA held technical and sporting meetings on April 15–16, with a high-level stakeholder session scheduled for April 20 to finalise the preferred course of action.

FIA Closes Qualifying MGU-K Energy Loophole Exploited by Mercedes and Red Bull
The FIA has closed a qualifying loophole exploited by Mercedes and Red Bull, in which teams were using the MGU-K’s emergency power mode to deploy full battery energy deep into a lap before cutting off the system abruptly. The technique triggered a 60-second lockout of the motor-generator unit, creating unpredictable car behaviour and a significant performance advantage in qualifying. The FIA determined it posed safety concerns through erratic mid-lap deceleration. Teams have been warned the emergency energy mode must be reserved for genuine technical situations only, with telemetry to be monitored closely and penalties issued for misuse. The directive took effect during the April break.

Red Bull Identifies Fundamental RB22 Concept Error Leaving Verstappen Well Off the Pace
Red Bull Racing have identified a fundamental design flaw in the RB22: the team prioritised low drag over high-speed corner performance, leaving Max Verstappen averaging 1.7 seconds per lap behind race winners in China. The team has admitted to “significant shortcomings” in the car, with engine reliability compounding the difficulties — a power unit failure stopped Isack Hadjar in Australia. Verstappen has been among the loudest critics of the 2026 regulations, though technical leadership under Laurent Mekies acknowledges the car’s core concept is contributing to the deficit, not the ruleset alone. The team is using the five-week April break to plan corrective development before Miami.

Aston Martin Fighting Honda Vibration Crisis After Scoreless Start to 2026 Season
Aston Martin have failed to score in all three opening races of 2026, making them the worst-performing established team in F1’s new era. The team is battling severe high-frequency vibrations from its Honda power unit — a problem serious enough to force Fernando Alonso’s retirement in China after he lost feeling in his hands and feet. Lance Stroll has indicated the AMR26’s problems extend beyond the power unit alone. With Adrian Newey’s design influence still months from reaching the track, Aston Martin and Honda are using the five-week April break to address the vibration issue as their stated top priority before the Miami Grand Prix.

Pirelli Nurburgring Tyre Test Complete; McLaren Loses Day One Time to Technical Failure
Mercedes and McLaren completed a two-day Pirelli development tyre test at the Nurburgring on April 14–15, focusing on C3 compound construction variants and softer options. George Russell set the Day 1 benchmark with a 1:33.899, but McLaren’s programme was disrupted when a technical failure restricted Oscar Piastri to 65 laps against Russell’s 127. Championship leader Kimi Antonelli and Lando Norris took over for Day 2, completing 109 and 108 laps respectively. The session provided Pirelli with a substantial data set ahead of the Miami Sprint weekend, where the demands of the fast street-style circuit will put the updated compounds under race conditions.
Verstappen Contests Nurburgring 24-Hour Qualifiers in Mercedes-AMG GT3 This Weekend
Max Verstappen is competing in the ADAC Nurburgring 24 Hours Qualifiers this weekend — a pair of four-hour races on Saturday and Sunday — as part of his preparation for the full 24-hour event later in 2026. The four-time Formula 1 champion is driving the No. 3 Mercedes-AMG GT3 for Mercedes-AMG Team Verstappen Racing alongside co-driver Lucas Auer. Verstappen has been open about his desire to race at the Nordschleife, and the extended break in the F1 calendar — produced by the cancellations of the Bahrain and Saudi Arabian Grands Prix — has given him time to accumulate seat time on one of motorsport’s most demanding circuits.

South Korea’s Incheon Launches Pre-Feasibility Study for F1 Return with 2028 Target
South Korea has taken a formal step toward bringing Formula 1 back, with Incheon launching a pre-feasibility study for a proposed street circuit near the Incheon Bridge and Songdo waterfront. The circuit would be 4.96 kilometres long, incorporate 15 corners, and allow a top speed of 337 kilometres per hour. A financial feasibility study has already returned a positive assessment. Targeting a 2028 debut, the city must still secure government backing, appoint a race promoter, and enter formal negotiations with Formula 1 management — steps that have not yet begun. South Korea last hosted F1 from 2010 to 2013.

Antonelli Heads to Miami as Youngest-Ever F1 Championship Leader; Sprint Format Set for May 1
Kimi Antonelli heads into the 2026 Miami Grand Prix as the youngest championship leader in Formula 1 history, at 19 years and 216 days, after winning consecutive races in China and Japan. The Mercedes driver holds 72 points — nine ahead of teammate George Russell — as the series returns from the five-week break forced by the cancellations of the Bahrain and Saudi Arabian Grands Prix. Miami is the season’s second Sprint weekend: drivers contest Sprint qualifying on Friday, the 100km Sprint race Saturday morning, and conventional qualifying before Sunday’s main event. McLaren and Ferrari both aim to cut into Mercedes’ dominant early-season advantage at the Miami International Autodrome.
