Next move was just pointing out that the Tesla overstates it’s range and the Porsche understates it. InsideEVs Tom M came to a similar conclusion. The two cars, while not identical, are much more similar in range than the epa suggests.

The Ahr rating of the Taycan battery (93.4kWhrs) is very similar to the Nissan 40 kWhr Leaf (115 Ahrs), with the same parallel structure
(Taycan - 198S, 2P, Leaf - 96S, 2P).
The Taycan is the first production vehicle with a system voltage of 800 volts instead of the usual 400 volts for electric cars. This enables consistent high performance, reduces the charging time and decreases the weight and installation space of the cabling.

The two-tier Performance Battery Plus used in the Taycan Turbo S and Taycan Turbo contains 33 cell modules consisting of 12 individual cells each (396 in total). The total capacity is 93.4 kWh. The cells themselves are so-called pouch cells. In this cell type, the stack of electrodes is not enclosed by a rigid housing, but by a flexible composite foil. This allows optimal use to be made of the rectangular space available for the battery and a reduction in weight.

Efficiency lower than Tesla? Range lower than Tesla? Not in independent testing.

That's not a test it's a stupid inaccurate extrapolation with no scientific basis. Range is not a snapshot nor is SOC a comparative measure between two different cars.

It may not be highly accurate, but it is both scientific and non-stupid. Unless one or both of the cars have SOC estimates that diverge a lot from either the actual SOC or from the other car's SOC at the same reading, the above test is a reasonable attempt at comparing real world ranges. (If both cars' SOC displays diverge about the same amount, in the same direction, from actual SOC, then there is no major problem there.) They controlled for the route, the temperature, for speed, and for climate control usage. This is better than the EPA range test in several important ways.

IEVS:
UPDATE: Porsche Admits Taycan Burned Down; Video In Florida Shows It
https://insideevs.com/news/399288/porsc ... n-florida/

The German company is already aware of the incident, which is under investigation.

Porsche has confirmed that a Taycan has caught fire, a fact which had been supposed after images of a burned car in a garage surfaced on Twitter last weekend and were suspected to be Porsche's EV. . . .

Also IEVS:
Bill Gates Tells Marques Brownlee He Got His First EV: A Taycan
https://insideevs.com/news/399217/bill- ... ev-taycan/


. . . It is a pity Brownlee did not ask Gates why the Taycan and not a Model S, for example. Was it a matter of customer loyalty? Was it a concern about the known issues a Tesla has? What made Gates choose a Porsche over a Tesla? It is all probably down to personal taste, but that could lead to a fascinating discussion.

When Brownlee asks what he misses in his experience with the Taycan, Gates says that range is still a big deal. And that he does not like the "pervasiveness of charging" compared to filing a gas tank. And he agrees with Jason Fenske that energy density is still an issue. . . .

Note: the interview was mostly about other issues involving the Gates' Foundation. like improving 3rd World public sanitation.
