And Formula 1 engines are only meant to last hours (yes really, most engines don't even last one season), albeit at ridiculously high stress levels.
If we extrapolate from this, where high performance drag cars typically last minutes (20 years ago they only lasted seconds), that would mean this engine might only be good for a couple of hours of driving around the track. Assuming this is true (I am not saying it is), this engine would be pretty worthless for anything other than being a collector's item or being used for 1 or 2 races before it had to be retired.
and F1 tires only last a few laps. it’s all designed in. the F1 engines don’t expire in a few races because they can’t build them more robust, they expire in a few races because the rules require them to last that long. they could last all season (yes, with same performance) if they were required to do so.
Indeed. Back in the days they used to weld the cylinder heads to the engine block before qualifying, so they could run it that bit harder to get that extra bit of performance. Obviously not something that increases the lifespan of the engine...
Similarly in current F1, they know quite well how much life they have of the engine, and how much life a quali lap takes from the engine compared to a calm outlap.
If the regulations mandated a single engine per season they could do it, though they'd mostly just turn everything down.
I'd be surprised that they could build tires to go on for 22 GPs with the same performances, but who knows. The goal was raw speed when there were multiple manufacturers. The only year with a rule to forbid tyre changes during a race was 2005. Maybe you remember that Indianapolis GP with only 6 cars racing because thr banking destroyed the tires of the other manufacturer (which won all the other GPs.)
7 races per engine including Saturday practice and qualifying. It's about 5 hours per weekend times 7. 35 hours, which a commuter car does in about 10 days.
> yes really, most engines don't even last one season
"Even" one season? If they last more than one race it means they didn't push it hard enough so it makes sense that the engine last just marginally more than the race.
The new rules set the limit at 3 engines per season, which is 21 races plus testing. So it's a balancing act, but you definitely need to reuse the engine for more than 1 race.
And for those not in the know, a F1 race is ~305km, and they have do two days of practice plus qualifying in a race weekend using the engines they have (same engine for qualifying as for racing). There's some more detail in this[1] article, where they point out the Mercedes F1 engine did over 3000 miles (~4900km) during pre-season testing without issues (most in race-like conditions).
That said, from my impression it is usually the turbo or the hybrid systems that break down, it's rare for the actual engine block to be the issue barring specific production issues.
