Kimi Antonelli labels poor F1 starts as 'fundamental' issue

Mercedes rookie Kimi Antonelli has identified a "fundamental" issue with his race starts, a problem that has cost him 18 positions on the opening lap across the first three races of the 2026 season. Despite this significant handicap, the 19-year-old remarkably leads the Drivers' Championship after securing victories in China and Japan, highlighting both his raw pace and the urgency of finding a fix.

Why it matters:

Consistently poor starts can derail a championship campaign, forcing a driver to fight through traffic and compromising race strategy. For Antonelli, solving this is critical to maintaining his title lead over a fast and experienced teammate like George Russell and with other teams like Ferrari and McLaren closing in. The issue is compounded by new-for-2026 start procedures, making his personal adaptation a key technical and psychological battle.

The Details:

• Antonelli's lap-one struggles have multiple causes: a lack of battery power hampered him in Melbourne, while in Japan, he suffered wheelspin from dropping the clutch too deep.
• The problem persists amid regulatory changes. The removal of the MGU-H for 2026 requires drivers to rev their engines high for at least 10 seconds to spool the turbo, altering the start procedure.
• In response to safety concerns over potential stalls, the FIA is testing a new "low power start detection system" in Miami. This system identifies cars with low acceleration after clutch release and triggers automatic MGU-K deployment for a minimum acceleration boost.
• Antonelli, however, believes this systemic tweak won't solve his core problem. He stated his issue is more fundamental, related to his clutch paddle and hand positioning, requiring a physical adjustment to his technique and equipment.
• The team has used the spring break to analyze the problem and practice starts. Antonelli confirmed they have identified the root cause and are working on a solution, though he cautioned it involves changes that "are not going to be that straightforward."

What's next:

Antonelli will use the Miami Grand Prix as a live test to see if initial steps provide improvement, with the following break before Montreal offering more time for development. Mentally, he is preparing for a sustained title fight, acknowledging the pressure but focusing on a race-by-race approach. "I’m just going to try to focus race by race... trying to do my best and focus on the progress," he said. If Mercedes can quickly resolve the start issue, Antonelli's inherent speed could make him a formidable championship contender.
