The Lance Stroll Honda engine deficit has become the defining issue of Aston Martin’s season. Stroll says the team is losing between one and two seconds a lap every weekend because of Honda’s power unit, a gap he believes is the single biggest factor holding the car back.
Speaking about the scale of the shortfall, Stroll made clear that it isn’t just raw power causing the trouble. Drivability through the throttle range and straight-line speed are the areas costing Aston Martin the most time on a typical race weekend.
Stroll Attributes Lap Time Deficit to Honda Power
Stroll has been consistent in pointing to the engine rather than the chassis when explaining Aston Martin’s form this year. He says tracks that reward power hurt the team most, while circuits with fewer straights let the car’s strengths show through.
“The tracks with long straights are worse for us,” said Stroll. “You know, Budapest was probably our best race of the year, with just a lot of corners and not many straights. So, yeah, we have to work on the drivability stuff. That’s a big limitation for us and then just power down the straights.”
That assessment lines up with what fans watched during Stroll’s difficult Baku weekend exit, a track built almost entirely around a long straight and heavy braking zones, exactly the layout Stroll flags as Aston Martin’s weakest.
Honda ICE Benchmark and Upgrade Resources
The numbers back up Stroll’s complaint. Honda’s internal combustion engine was measured down against the Red Bull-Ford ICE benchmark, a gap wide enough to trigger extra development resources for Honda under the sport’s ADUO allowance rules.
Honda has already used some of that scope this season, introducing an upgraded turbocharger as its second major update of the year. It’s a step in the right direction, though Stroll’s comments suggest the Lance Stroll Honda engine deficit has not closed by anything like the margin Aston Martin needs.
The broader picture fits into the wider 2026 engine regulation debate, with manufacturers still finding their feet under rules designed to push hybrid power and efficiency further than ever.
Driver Stability and Aston Martin 2027 Timeline
None of this has shaken Aston Martin’s faith in its driver pairing. The team has confirmed that both Stroll and Fernando Alonso will stay on for the 2027 season, giving the squad continuity through what has been a frustrating campaign on power.
That stability matters for a team banking on long-term gains rather than a quick fix. Honda’s engine programme is still maturing, and Stroll’s remarks make clear the drivability and straight-line shortfalls remain the priority before Aston Martin can close the gap at the front. The full breakdown of his comments is available in the Motorsport.com report on Stroll’s comments.
