I agree with the idea that the numbers are surely not true. It is every teams interest to not to share correct numebrs and to downplay their own performance.
Well if according to ADUO Ferrari is around 4% behind in ICE performance, then it is about 20HP.
Actually, compared to road cars to whom peak power (or power number around peak power RPM) isn't that important ; in F1 cars peak HP is a very reasonable measure of performance, vide the simple fact that the % duration of full throttle and % duration of near-peak RPM (in all gears) over a laptime duration, is a much much higher proportion.Just_a_fan wrote: ↑22 Jun 2026, 23:53A simple 10hp increase to peak is one thing, raising the entire curve by 10hp is quite another. One might even publicly "boast" of a 10hp peak gain whilst hiding a mid curve rise of multiples of 10hp.
Any additional power available once the car is not grip limited is going to give you a lap time improvement.
Hasn't been A1 for a decade and a half.deadhead wrote: ↑22 Jun 2026, 14:40Depends on the length of the track.Sidiamal wrote: ↑22 Jun 2026, 14:24There was a video at one point of James Allison during the weekend of Singapore 2015 I believe explaining how much 10 HP is worth in lap time. 8 HP would be around 0.125 or so if memory serves. Not that much but every little bit helps, the gap to pole was 0.064 last week, half as much as the theoretical gain.
10hp is not worth the same amount around A1 and Spa for example
10 HP today is worth more than 10 hp in 2015, because in % terms it amounts to higher relative gain.Sidiamal wrote: ↑22 Jun 2026, 16:29I'd think so as well. SM and the structure of the new PUs. The split was 80/20 back in 2015, now it's 50/50 the ICE is responsible for much less of the power output. How that shakes out exactly I'll leave to the engine gizmo heads, I'm not nearly steeped enough in that department to understand.
30 hp increase is a pipe dream
Under the current rules that's more than 5% increase, aduo 2.
The toothed diffuser proposed by Mercedes heading towards a ban, with almost immediate effect. Ferrari's legality check office had requested clarification from the FIA, while the aerodynamicists were ready to bring back to the car an even more extreme version of the concept.?
Any power you add lower down the rev range will bring a benefit - the cars don't go from idle straight to maximum revs, they build and any additional power added during that rising rev phase will absolutely accelerate the car harder. That allows more punch out of a corner, for example, and thus enables top speed to be reached sooner.venkyhere wrote: ↑23 Jun 2026, 02:10

Exactly this. This is the exact reason why if you integrate the area under the power curve, the engine with the most area is almost always the best.Just_a_fan wrote: ↑24 Jun 2026, 17:21Any power you add lower down the rev range will bring a benefit - the cars don't go from idle straight to maximum revs, they build and any additional power added during that rising rev phase will absolutely accelerate the car harder.

Not so sure about this logic because cars really aren't "lower down in the rev range" in the power limited parts of the track.Just_a_fan wrote: ↑24 Jun 2026, 17:21Any power you add lower down the rev range will bring a benefit - the cars don't go from idle straight to maximum revs, they build and any additional power added during that rising rev phase will absolutely accelerate the car harder.

The only time a car really goes below 10k rpm whilst on throttle is out of some of the slower corners, and on initial acceleration out of those corners you are far more traction limited than power limited, especially with 350 kW of MGU-K helping. By the time the car actually needs the full grunt from the ICE you are already back in the optimal rev range and pulling gears.
