Mercedes' 2026 Car Feels Better on Track Than in Simulator

Mercedes' 2026 challenger is already exceeding expectations, with drivers reporting the W17 feels better on track than it did in the simulator. The team completed a productive first day of testing in Barcelona, logging 149 laps between George Russell and Kimi Antonelli while addressing initial concerns about engine driveability.

Why it matters:

With the new 2026 regulations representing the biggest technical overhaul in the sport's history, a smooth start is critical. Mercedes has been tipped as an early favorite, and resolving the "big question mark" surrounding the new power unit's drivability suggests the team is well-prepared to challenge for the championship immediately.

The details:

• Sim vs. Reality: Trackside engineering director Andrew Shovlin noted that in several areas, the car's behavior on asphalt is superior to the virtual data. This discrepancy is a positive surprise, allowing the team to focus on performance rather than fundamental correlation issues.
• Power Unit Progress: The new engine, which relies heavily on the uprated MGU-K for nearly half its power deployment, is in a "pretty good place." Antonelli confirmed the driveability is strong, dispelling early fears.
• Driver Feedback: Russell described the new breed of 2026 cars as having "pretty impressive" power, noting that watching Antonelli was "probably the quickest I’ve ever seen an F1 car pass here."
• Project Scale: Shovlin emphasized the magnitude of the challenge, citing completely new electronic systems and fuel development with Petronas alongside the chassis and engine changes.

What's next:

While the team remains cautiously optimistic, Shovlin admits they are in the "embryonic stages" of the program. The focus now shifts to longer runs and further data analysis before the season opener in Melbourne, where true competitive order will be revealed.
