thewayneSwiss and German engineering students are doing some great things!
First up, the Swiss. Swiss students built a car that did zero to 62 MPH (100 KPH) in UNDER ONE SECOND! That is some very impressive engineering. And to top that off, the car achieved that in FORTY FEET! Oh, and they designed, built, and completed the run in ONE YEAR!
The run is so short, and the speed is so low that the car isn't affected by conventional downforce like, say, a Formula 1 car would be, so it took some very impressive aerodynamics to generate it. You also had to control the acceleration in such a way to have zero tire slip because if you're spinning those tires, you're wasting energy and losing speed.
I'm curious how much energy was left in those batteries at the end of the run! My guess is that it that they were very low.
Oh, and the car was driven by a woman. So go, girls!
This will be a very nice line for the students to put on their CVs when they start job-hunting!

The second record was set inside a German airport hanger, and went in a different direction. A team of seven drivers drove the vehicle that they built for distance, not speed.
From the article: "The car, called muc22, looks more conventional than the Swiss speedster, if only a little. The diminutive coupe in this case was built for efficiency, and in a six-day test at Munich airport, it set a new distance record on a single charge (for a non-solar EV): 1,599 miles (2,574 km), with less battery capacity than many plug-in hybrids—just 15.5 kWh." (emphasis mine)
At a speed of 26 MPH. Not exactly a commuter car, but an impressive technology demonstration. It was driven inside a hanger to eliminate weather factors disturbing the run.

Date: 2023-09-15 04:56 pm (UTC)The long-distance one is more interesting to me, even though it's at low speeds, because I'd like to believe that most of the driving that people do is in-town and at speeds pretty close to that 26 MPH. If there's a long-term battery that you can use for those kinds of driving and then only needing to charge up a small battery, that could take a lot of possible gas cars off the road by producing an affordable long-range errands-and-commuting kind of car. (Admittedly, where I am, there's a lot of people who can't live anywhere near their workplace, so that's no help, but for places where that is possible, that would be pretty good to do.)

I personally think high acceleration like that is ludicrous, but some people will shell out big bucks for it and having your name in the books for having set a world record does look good on your CV. It's a constant argument about range re EVs that people don't need 300 miles worth of battery in them. The problem, of course, is that a lot of people in the USA don't live in concentrated cities and do need higher battery range, and a lot of people in those concentrated cities don't have the ability to charge overnight because they don't have garages! There's a lot of chicken and egg paradoxes regarding EVs that have not yet been sorted.
