“Red Bull gives you wings” stands as the most successful and recognisable marketing slogan worldwide. But what happens when the Red Bull‘s wings get clipped? Another team rises.
In Brackley, Mercedes have been sharpening their arrows for some time. Their sights are now firmly set on claiming the drivers and constructors title. This analysis dives deep into how exactly Mercedes delivered the best car to start the 2026 regulation changes.
Mercedes’ Immersion Cooling
The 2026 regulations introduced a massive hurdle for all teams. A tripled MGU-K output (350 kW) paired with a quite restrictive 4 MJ battery. Most teams opted for the “old way” for battery cooling using cold plates, which struggle to pull more than 2500 units of efficiency.
The result? Rivals are forced to “clip” power early as their batteries overheat, or risk simply not working anymore.
Mercedes, however, found a new way. And that is immersion cooling. By dunking the battery in a dielectric fluid that covers the battery cells without causing a short circuit, they’ve achieved 6000 units of efficiency.
This “advantage” allows George Russell and Kimi Antonelli to maintain full electrical deployment for at least 28 seconds per lap. While others have to slow down to let everything cool off, the W17 recharges 8.5 MJ of energy per lap, effectively allowing its drivers to keep pushing while the rest of the grid manages heat.
Simply put, an engine with the ability to hold 350 kW until 288 km/h enjoys a huge advantage.
Engineering in the Grey Areas
The 2026 regulations have shifted to 100% sustainable fuels and a reduced fuel flow, dropping from 100 kg/hr to just 75 kg/hr. That demanded a total reinvention of the combustion chamber.
With the Internal Combustion Engine (ICE) now capped at approximately 400 kW, Mercedes have stopped engineering ways to get more and more raw horsepower in favour of thermal efficiency.
The “secret” of the W17 power unit allegedly lies in its compression ratio. While the FIA regulations require all teams to have a strict 16:1 ratio, sources suggest Mercedes have engineered a bypass.
By exploiting the thermal expansion rates of specialised alloy components, the engine reportedly “self-adjusts” to an 18:1 ratio once the block reaches its 130°C operating temperature.
This higher compression allows for significantly more complete combustion, which comes from every drop of the sustainable fuel. The result is an almost seamless transition between kinetic recovery and internal combustion that the other teams simply cannot match with their current setups.
The Active Aero Controversy
Beyond the engine, the Mercedes wings have generated plenty of attention. The 2026 rules state that wings must complete their active aerodynamics between within 4 tenths.
However, rivals have questioned whether the German constructor are flirting with the limit of the regulations.
The W17 utilises a two-phase front wing closure. While the rear wing follows the 400ms rule, the front wing completes its transition in 800ms, closing halfway at the limit and finishing the movement more slowly.
This hydraulic tuning maintains a more stable centre of pressure, preventing the “rear-end snapping” that plagued cars like the RB22.
By smoothing out the balance during braking, Mercedes enables its drivers to carry significantly more speed into the turn, and not worry about their rear-end like others have to.
Qualifying in Numbers
When you look at the past three rounds, Mercedes have been unstoppable. After all, they have triumphed 3/3 races so far. Let’s, for example, look at a few qualifying sessions.
The data from the China qualifying shows a harsh reality for the rest of the teams: Mercedes isn’t just leading. Kimi Antonelli secured pole position with a 1:32.064, but the W17’s true dominance is the inter-team delta.
George Russell followed in P2 just +0.222s behind, while Lewis Hamilton managed to somewhat keep up, being only +0.351s away from pole.
By maintaining such tight qualifying margins between the two Mercedes while completing significantly lower lap counts (here: Kimi achieved such in 15 laps while George in 13), Mercedes has demonstrated a performance that allows them to find an extra maximum one-lap pace without overstressing the M17 power unit.
And that? That becomes really hard to beat. That can be noticed in the fact that no other team has taken pole this season yet.
The data from Suzuka confirms that Mercedes is racing a whole different way than the rest of the field. Kimi Antonelli’s pole-position lap of 1:28.778 stands as a masterclass, achieved in just 15 laps.
While George Russell secured the front-row lockout with a 1:29.076, the delta of +0.702s between the two drivers is less a sign of struggle for Russell and more a sign of the W17’s sheer dominance on track.
Opinions and feelings for the new season
With a massive advantage of having only had one season in previous regulations, Antonelli is learning the new car, while other veterans have to unlearn habits that don’t work anymore. Kimi Antonelli expressed excitement for the new car at the Mercedes-AMG F1 Team season launch.
“Yeah, I’m very, very excited. Of course, last year was a massive learning experience. And definitely, this year is going to be a new opportunity for everyone. It’s completely something completely new,” he said.
After the race in Suzuka, Andrew Shovlin, the Mercedes Trackside Engineering Director, spoke in an interview for the Formula 1 website, stating the team has got a lot more to perfect in the car.
“[…] As it happened, [George] dropped to P3 and lost a further place to Lewis when he hit the harvesting limit too early in the lap,” Shovlin stated. “He then had another frustrating issue where a bug in the software code… caused the power unit to go into superclip, which allowed Charles to pass.”
Despite the early-season dominance, Shovlin remains cautious: “Clearly, there is a lot that we need to work on. We’ve made a great start to the season, but our competitors are closing in.”
The Verdict
The extent to which the FIA introduces any mid-season regulatory changes remains to be seen. However, the fact remains that Mercedes have build a top machine.
When F1 returns after the April break, rivals will be eager to see if they can close the gap to the W17.
