Seven minutes for the Nordschleife? Sabine Schmitz could have done that with a van. But honestly, ther are a Lot of production cars that went considerably faster. And the non-production Porsche 919 Hybrid EVO did it in 5:19, which is an entirely different league.

and here we learn that fast and a straight line does not necessarily mean fastest round the track.

There is a “car” in my hometown in Coventry that goes (I think) 700 mph, but I can only do it in a straight line because it’s powered by two turbo jet engines

That's probably one of the least interesting records. Besides the tires, what's the problem reaching that speed? Need a big engine and some downforce. This is much easier than building a car that cam set a record on the track.

I guess it's interesting that you can do it in a street legal production car.

And it is very difficult to fine a straight road that is long enough to reach the top speed. At the Volkswagen test track the Bugatti had to leave the oval with 200km/h to reach top speed on the connected 9km straight track.

It seems to me like building the fastest EV has nowhere near the complexity of building the fastest ICE car. Way too many moving parts and fine tuning required to get an engine to 440Kmh (Chiron SS) than an EV with 4 big motors.

This is why the Ring is the absolute benchmark of how well rounded a car is.

Yet none of the other mainstream automakers has done so.

Funny that it packs 3000hp while the Chiron « only » needs 1600hp to achieve mostly the same speed.

There was quite an interesting youtube from Engineering Explained speculating it had enough power to do 400 mph. There may have been other constraints limiting things like the tyres being safe and apparently the battery only has capacity for 2 mins at full power, plus bits may overheat and the like. ( https://youtu.be/z6q7du1q2U8 ) It's also interesting that the fastest time on the Nürburgring at 5 min 19 was from a…

> 5 min 19 was from a Porsche hybrid with 900 hp

You're talking about the non-production Porsche 919 Hybrid Evo race car. A Corvette ZR1X did 6:49 with a third of the HP
