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.

are we bound to see a huge increase in speed limits as EVs start to dominate?

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.

It's the fastest EV lap currently.

Sabine Shmitz did the 19,100m length in 10:08.49 using the ford transit van.

That's a far cry from 7:14

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.

> This is much easier than building a car that cam set a record on the track.

Why ? You "just" need a car that can steer and brake, what's the problem with steering and braking ? Need a steering wheel, good brake pads and tires

Well, while impressive I would like to see them do a second lap right after or try the Nürburgring (seems they have, way off pace versus ICE cars).

One thing many car channels are pointing out is that the car could've reached even better numbers looking at how easily it reached its record pace. I wonder if the bottleneck is the battery. Hell, it supposedly discharges at full power in 2 minutes.

(Edit: noting they did the ring)

Which shows that ICEs are a ridiculous choice for performance cars?

No, EV are too heavy. On an actual track they loose to lighter ICE cars since they corner better. Plus for a prolonged race EV might run out of battery.

Yet none of the other mainstream automakers has done so.

Are they even trying? It seems like the only reason to do this is for publicity. Maybe a manufacturer that's known for their ICE vehicles would want an opportunity to show off their electric vehicle engineering but I don't know any it would make a difference for. US manufacturers even sell electric trucks. It's not like any mainstream manufacturer needs to rebrand to sell electric vehicles.

> Are they even trying?

Nope, probably too busy faking emission results, lobbying at the EU parliament , or designing overpriced mid tier cars in the US

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

Yeah, the weight and battery are the limiting factors. Their battery tech is impressive though.
