Now _that_ is hot rodding. Can't wait to see what the drag strip looks like in ten years!

I was thinking the same. It is interesting to think of different fuel modalities. Liquid fuels seem to have a throughput advantage for now. The article doesn't seem go into electrical depth. From the pictures, it looks like they are powering all four wheels at the hub.

This articles says" The vehicle weighs just 140 kilograms and has an output of 326hp." https://www.swissinfo.ch/eng/swiss-students-break-world-reco...

A top fuel dragster accelerates from a standstill to 100 mph (160.9 km/h) in as little as 0.8 seconds (less than one third the time required by a production Porsche 911 Turbo to reach 60 mph (96.6 km/h))[1] and can exceed 297 mph (478.0 km/h) in just 660 feet (201.2 m). This subjects the driver to an average acceleration of about 4.0 g0 (39 m/s2) over the duration of the race and with a peak of over 5.6 g0 (55 m/s2).

Earlier quoted context omitted.

...and lithium fires. Unfortunately, I think there will be pearl clutching and new rules that allow gas/diesel powered vehicles only "due to safety", at least my guess.

.....the what now? Have you watched any drag strip racing, like, ever? Cars regularly go up in flames. The suggestion that normal ICE cars would be allowed over EVs for "safety" is actively hilarious.

I think you missed the point. For a petrolhead, a lithium fire is like a nuclear fire for a Green Part voter in Germany.

That's almost 3Gs of acceleration. Impressive!

I did the calculation manually from memory: 3.6 km/h = 1 m/s. 1 g = 9.8 m/s^2.

So, 100 km/h = 27.8 m/s. 36 m/s in 0.956 s is an average acceleration of 29.1 m/s^2. Divide that by 9.8 m/s^2 to get 2.96 g.

On a related note in the sports car community its been interesting to watch Acceleration stop being a mark of a performance car. There is even a lot of chatter around this being the end of the supercar segment since there are family wagons that can now do 2 second 0-60 runs. On top of that the speed is now too much for anyone to reasonably use off a drag strip or circuit. Now there is a huge emphasis on engagement, d…

Acceleration was never really the top metric for super cars. It was more performance at high speeds, with high end cars like the Bugatti Chiron Supersport 300+ going up to 489 kmph (that is a lot in case you wonder). Part of the super car segment will go electric, that is for sure, but I do not see the end of the super car. Look at luxury watches. They are booming despite a Casio GShock with Multiband beating the shi…

Super car segment is well below Bugatti. Thats a 2.5 million dollar car. Super cars are between 150k usedish and a million. Plus a lot of other vague definitions. Most people say call the 911 the dividing line of a supercar and top of the sports car range.

In general this segment is dying off, chasis are being reused for 10+ years in the market, tons and tons of special edition and reissues. most of the new work is being done in the Hypercar segment which is almost just a nonsensical money-fight space. And they were, for the most part, defined by speed in the public eye. If you wanted feelsome-ness you just go a Cayman or a Lotus.

We see this same sentiment in comments on this very website. Comments like "Straight line acceleration doesn't matter", for example. Except, as a driver, I never accelerate in a tight curve. Once I got an EV, aggressive drivers were no longer able to block me from merging into traffic; if anything, I was able to easily get away from them if necessary. I believe what we are seeing is car enthusiasm being pushed furthe…

The majority of the long-tail is just becoming "its really expensive" and "its an investment asset" unfortunately.

The impressive thing to me is the level of traction needed to do something like this. It seems they're taking old tricks and building a "sucker car". https://www.roadandtrack.com/motorsports/a32350/jim-hall-cha... Still neat stuff. Race sanctioning bodies will need to update their rules or these will just be one off bragging rights.

Interesting. This is a Formula Student car, the european version of the Formula SAE. Powered ground effects were banned a long time ago in Formula SAE, but it seems like Formula Student does allow them.

8-wheels or more and tons of batteries

Remember the six wheeled Tyrrell P34 F1 racing car? Admittedly, ony the rear axis was driven, but that was one badass car (and it won a Grand Prix).
