>"All of mythen’s components, from the printed circuit boards (PCBs) to the chassis and the battery, were developed by the students themselves and optimised for their function. Thanks to the use of lightweight carbon and aluminium honeycomb, the race car weighs in at only around 140 kilos (309 pounds)."

Never knew about Aluminum Honeycomb -- before reading this article...

Let's do some quick Google searches for it:

https://www.google.com/search?&q=aluminum+honeycomb&tbm=isch

https://www.google.com/search?q=aluminum+honeycomb

Yup, apparently "it's a thing"... :-)

>"People also ask

What is Aluminum Honeycomb used for?

Aluminium Honeycomb - CEL Components - As core material, aluminium honeycomb is used in sandwich panels and it is utilised in: floors, roofs, doors, partitions, facades, working surfaces for automatic machines, laser jet cutting and for all products which require an optimal stiffness-to-weight-ratio."

>"Aluminium honeycomb is highly desirable due to its incredibly high strength-to-weight ratio and is applicable wherever lightness and strength are required."

So, very interesting!

Another material of the future, no doubt!

(I bet it works great as an electrical ground and/or antenna, too!)

A similar thing was done in F1 in 1978: https://en.wikipedia.org/wiki/Brabham_BT46 It was swiftly banned of course, since it worked too well.

Or not well enough? These cars would appear to be utterly dependent on maintaining a very specific distance from the track for the ability to stay grounded. You imagine going into a curve at high speed and the slightest body roll or debris on the track that might kick the car up an inch or so would break the suction and send the car flipping like a pancake.

That is an issue with all ground-effect cars, not specific to fan cars, which is why they were banned, but that happened much later. The fan car was banned because it gave Brabham an unfair advantage and the other teams didn't like it.

Fine. At the time when it ran that time it was the fastest, and faster than practically every sports car ever made. The nurburgring is about the most sports car track ever made. I don't really know how to measure anything about a car's sportiness other than its speed around the track generally agreed to be the most "Gran Turismo" style. If you want your own personal gatekeeping standards for "true sports car", whatev…

> Fine. At the time when it ran that time it was the fastest, See here: https://www.hotcars.com/fastest-sedans-around-the-nurburgrin... And join with the list here: https://en.wikipedia.org/wiki/List_of_N%C3%BCrburgring_Nords... All five sedans that beat the Model S around the Nürburgring drove their laps earlier. The Plaid has only ever been the sixth fastest sedan around the 'ring. Which is excellent, but not what…

they've been playing this trick with top-fuel dragsters for decades - the "speed" was measured far before the end of the course. I think it was to keep the speeds below 300mph to help with track insurance.

They had a choice, lengthen drag strips everywhere or decrease the length of the race. Because physics / braking distance.

the trap speed was before the 1/4 mile and measured a speed lower than the time at the end

I don't think it's a "trick", it's purely for safety reasons. The distance change was made following a fatal crash.

So many old polite people on the Internet are going to be accused of being AI chatbots.

It has nothing to do with being polite and more to do with a recap of context, using similar language, before responding.

>The thing is, you can't actually feel motion at a constant speed In a vacuum. If you roll the window down, or if the atmosphere starts ablating you into a hot plasma then you may realize you're going very fast.

Or the air's going very fast past you. Who can tell?

Well, if you're on a 2D plain, it's pretty easy to tell. If the solid plain is stationary to your motion, then the air is fast. If the solid plain is moving, then it's a little tricker to figure out.

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…

Indeed. It's a case of "my favorite kind of car isn't the best performing anymore, but I refuse to accept that, so I'm going to change the definition of performance instead."

Pretty much what is destroying the notion of 'sports car' and 'supercar' Enthusaists don't want to admit a family SUV can now blow them away on the road or the track -- so you have to fallback on things like 'feelsome'. its a huge sore spot in the community
