Porsche Taycan breaks the Guinness World Records for coast-to-coast charging
newsroom.porsche.comOn the Taycan forum [0] a few people were working the math out and figured out a theoretical 2:30 charge route. It requires 55MPH cruise and a few other things, but doesn't seem that out of the realm of possibility for a manufacturer backed PR stunt.

The one that I saw that worked it out said this: "Here’s a scenario that abrp says would cost 2:30 in charging: - max speed set to 55mph (yawn) - efficiency 200 Wh/mi @65mph - charging stops set for Shortest Legs - start with 100%"
Notably, 200 wh/mi is at least 20% too optimistic. OTOH, ABRP seems to underestimate the charge KW rate a little bit, but it doesn't seem to be enough.
They should publish the details for public examination. It seems like this comes with some important asterisks.
About a year ago, the EA chargers were a crapshoot as to whether the rate negotiation with the vehicle would work. Looks like they either solved that problem, or had technical support from EA to ensure they wouldn't be delayed on their trip.
The latter is more likely than the former, and I’d suspect reconnaissance to add to that support.
We’ve driven the west-coast corridor a bunch and contemplated several getting a different brand EV to go with our Tesla. Often seen/watched/checked-on-ABRP the EA sites down to just one or two working CCS chargers e.g. at Woodbury, OR. It put us off this year at least.
Previous Cannonball EV record sets the tone
>Conner tells us that he had the engineers at both Porsche and Electrify America on speed dial for this run. Despite it being New Year's Eve, he was able to work with the teams to ensure that the car was operating to its potential (despite the bugs) and the chargers he was visiting were both working and reliable.
The driver said that he had to change plugs several times. It seems clear that failed sessions were not counted as charging time.
The driver posted some more details here: http://www.cleanmpg.com/community/index.php?threads/56827/
"I had to move from cord to cord or cabinet to cabinet at some locations, but I was never stranded."
Who cares as long as the Taycan has marginal whiplash protection due to its seats _at very low_ speeds. Basically unusable. Nobody needs an expensive death trap, as an alternative to a 0 star Renault ZOE.
The 5 star Euro NCAP is mostly worthless on rear impact: https://www.businessinsider.com/porsche-taycan-5-star-crash-... " In these seat and head-restraint tests, Euro NCAP propelled a dummy with a realistic spine on a sled at both 10 and 15 mph, mimicking a rear collision. This is the type of crash most likely to inflict a neck sprain or whiplash injury. In general, manufacturers design seats so the headrests are as close to the back of an occupant's head as possible. As you can see by the orange in these diagrams, Euro NCAP assessed only "marginal" protection for the seat and head restraints in both the front and rear seats. "
Careful, don't adjust your seats in your Model 3 too much, or you'll be locked out as a "chronic abuser"!
"Taycan spends a total of less than 2.5 hours charging on a cross-country drive, the shortest charging time to cross the United States in an electric vehicle – the benchmark being 7 hours, 10 minutes, and 1 second"
What did he do, drive 25MPH average?
It is just advertising for Electrify America (owned by VW, like Porsche), and a worthless Record without telling how long they took to drive the whole distance.
A Tesla Model S crossed the country in 42 hours and 17 minutes.
Peak efficiency is at about 40-50mph, at least for Teslas:

It says on the chart km/h not miles/h!
It was about 5 days and with few details on total energy consumed.
In electric cars, there shouldn't be a huge difference in efficiency wrt to the speed
There actually is, because wind resistance goes up dramatically with speed.
... if you drive in a vacuum.
