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.

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 second fastest lap at the ring, and at least another five records in the top ten, are all EVs:

    VW ID.R
    Xiaomi SU7 Ultra
    Lotus Evija X
    F-150 Lightning SuperTruck
    Nio EP9
    Ford Transit SuperVan
#1 is the Porsche 919 Hybrid.

Cars built for straight line speed are rarely fast in a track – you won’t find the Bugattis breaking any fastest lap records either.

It's wild that after a hundred years there is still exponential progress in the power output of cars. The most unusual part to me is how EVs are fundamentally a consumer technology, so it all rapidly falls into mass production territory; eg. Xiaomi sells a 1527hp car for $73k. Horsepower is rapidly reaching 'solved' territory; even at its record speed, BYD's car wasn't even power limited.

Power for power’s sake is not necessarily a good thing.

There is some indication that putting rapidly accelerating cars on streets is leading to a proliferation of accidents.

I did not expect that anyone would take the first part of my comment seriously, but here we go. However, this year a Ford SuperVan 4.2 made the Nordschleife in 6:48.393, so even without Sabine Schmitz a van was faster than the BYD.

You are spouting such absurdities, that is a van in name only: https://carbuzz.com/nurburgring-ford-supervan-42-lap-record-... And it was driven by Romain Dumas someone far more qualif…

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.

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

>of how well rounded a car is.

For performance applications. None of these cars are great daily drivers.

The power isn't much use for driving down the road but maybe we can hook it to fans and have flying cars at last.

For sure; the US kills literally hundreds of thousands of people in ways other countries have solved, and bigger faster vehicles seems at odds with the lack of driver and infrastructure responsibility here. I don't want to make light of that.

I just had the numbers run to check this. About 650,000 fewer people would have died over my short life so far, if the US had the vehicle fatality rate of my home country.

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

On the track you need a good setup which has a lot of factors and can be very hard to achieve. Way more complex than going straight as fast as possible
