McLaren to study rivals before rushing 2026 car upgrades
McLaren will hold off on early upgrades to its 2026 car, opting to first understand the new platform at Barcelona and gauge rivals’ performance before committing to redesigns.
McLaren says it will not follow the trend of rivals who push early upgrades on their 2026 cars. Chief designer Rob Marshall says the team will use the five‑day Barcelona test to understand the new chassis and power‑unit before making changes. This means the British outfit will likely run the same spec in Melbourne for the season‑opening Australian Grand Prix.
Why it matters:
The 2026 regulations bring a brand‑new power‑unit architecture and tighter aero limits, so early tweaks risk upsetting reliability and performance balance. By establishing a clear baseline at Barcelona, McLaren can target upgrades with data rather than speculation, preserving development time.
The details:
- No pre‑season upgrades – McLaren will keep the 2026 spec unchanged for the Australian GP, unlike rivals planning mid‑winter parts drops.
- Testing plan – Only a shakedown on Monday; full on‑track work starts day two or three, with three days of running.
- AVL dyno work – The power unit is on the dyno at AVL in Austria, allowing core systems to be signed off before track time.
- Rival watch – Marshall said the team will be “inspired” by competitors’ solutions, using their data to shape McLaren’s own development path.
What's next:
McLaren expects to bring a near‑final 2026 car to Melbourne and then use the February Bahrain tests to validate early refinements. Mid‑season upgrades will focus on aero fine‑tuning and hybrid mapping once a solid performance baseline is set.
