Is the Piech Mark Zero using a supercapacitors?

80% charge in 4m40s – sounds like they have had a breakthrough in Supercapacitors

The Piech Mark Zero is taking concrete shape. We have the first teaser shots sent out by the company co-founded by Ferdinand Piech’s son Anton ("Toni") and Rea Stark Rajcic; now we get illustrations that are a lot more detailed, and some promising background on this upcoming supercar.

We now know the dimensions of the supercar, which is still in the concept stage: At 174.5 inches long, 78.4 inches wide, and 49.2 inches tall, it is slightly shorter and lower but significantly wider than a Porsche 911. And its wheelbase of 103.1 inches is a lot longer than the 911’s, making for very favorable proportions.

Power will come from one front asynchronous and two rear synchronous motors, which can deliver just over 200 horsepower each. The target for the zero-to-62-mph sprint is 3.2 seconds, while top speed will be limited to 155 mph.

Unlike most current electric cars, which typically place their batteries under the floor, the Piech Mark Zero has its batteries in the central tunnel and atop the rear axle.

Even more questions arise around the type of batteries: Piech is guarding information closely at this point, claiming the Mark Zero will feature an entirely new battery type developed by Hong Kong–based Desten Group. The carmaker claims that this "special type of cell hardly heats up during charging or discharging phase."

This technology has two benefits. First, air cooling will suffice, which Piech says helps to shave off 441 pounds. Second, and even better, the charging time is reduced sharply. As it's fed by a charging infrastructure developed by Qingdao Tgood, charging the Mark Zero to 80 percent will take a mere four minutes and 40 seconds. This brings the recharging time to little more than the time it takes to refill a conventional car with gasoline or diesel. Keep charging to 100 percent, and the Mark Zero is claimed to be able to deliver a full 311 miles of range in the WLTP cycle.
