Explains the pricing on Porsche's.

Yesterday paid $5.00 CDN for a dozen eggs in Canada. That's for the fancier eggs from chickens that get treated nice. That's $3.50 US and we have bird flu too.

I'm not sure that people are really clear on the level of the current attack on EV's in the US. Including sabotage of charging stations, every program that provided any sort of incentive to EV's being cancelled or suspended, Tesla's self immolation with it's wannabe brown shirt leader. Could...

Sweet a dancing car. First there was the Plaid gap, now there is the dancing gap. Porsche needs to respond asap.

Off topic, but I thought this guy was supposed to be smart.

I have a MY2020, and though a few issues which have been fixed, nothing really major. Makes it sound like a quality control issue. I have not been turned off by the issues. More of what could it really be like if given a little more attention detail.

The problem is that the EPA test is not well understood and can be gamed. From the EPA procedure below there are optional correction factors (and two methodologies). In particular look at the 70% correction factor example for highway driving. So you shouldn't compare the EPA range rating with...

Just wondering if there are enough disgruntled owners out there that this is a real thing or not. Given the chaos in the new car segment, parts shortages, new manufacturers entering, general inflation, it's hard to a get clear read. Recent Taycan sales numbers aren't great, but the order...

Well, all those equations actually work and are used in real life. Not just nerd stuff. The real magic that uses the smarts, is actually in the material science.

Does EV vs ICE come into your analysis?

It just confirms that the Taycan is a really attractive car. (Though the numbers are badly skewed without the inclusion of Tesla).

EA, Taycan's kryptonite

Keep posting these kinds of videos. There is a ton of stuff out there that is really useful even if no one responds.

Hypothetically, you want to design a car and try out different geometries. Instead of building a full size car, you build a quarter size model. Test that in the wind tunnel. Providing the geometries don't change, scale it up. One of the reasons for dimensionless parameters is to allow...

The issue is that most people do not know the difference between the coefficient of drag and drag force and when and how to use them. Frontal areas for different vehicles can be found along with their Cd's. A quick check finds the frontal areas for Tesla's. So I can easily put together a...

Yes it does. See below, especially the fourth paragraph. Drag is measured experimentally. Substitute into the equation, rearrange and solve for Cd.

Cd includes the frontal area so is unique to the geometry of the car. These kinds of dimensionless constants are common throughout physics and engineering.

There are some studies out there on the effect of reducing ride height on the Cd for Teslas which should be a good proxy for the Taycan. One study here puts it at a reduction in Cd of around 8% for a reduction in ride height of 1.5 inches. But the details of how the Cd for the Taycan were...

Within 10 minutes I have seen articles that say he lost his job because he pushed electrification and upset too many powers, to he didn't get the software right so was holding up electrification.
