BYD said the Denza Z featured “shattering high performance” with over 1,000 hp and the ability to sprint from 0 to 62 mph (0 to 100 km/h) in less than two seconds, it didn’t reveal specifics....[New details show] the four-seat EV roadster is slightly larger than the Porsche 911 and closer in size to the Mercedes-AMG GT Coupe. The Denza Z is more powerful than both, with the 911 Turbo S delivering up to 701 hp and the Mercedes-AMG GT Coupe offering up to 1,153 hp.BYD’s electric supercar can reach a top speed of 217 mph and weighs 5,842 lbs (2,650 kg) for the hardtop version.The Denza Z will be available with a soft top and a souped-up track package that gains a massive rear wing spoiler.
Nearly six thousand pounds moving at over two hundred miles an hour is a lot of F=ma. That Mercedes is closer to three and a half. Wonder how good the spoiler is? How about the brakes?
It's strange to see luxury goods coming out of a Communist country; being consumed there by connected elites, certainly, but actually produced there? It seems like that should hardly be a priority in the Five Year Plan.
Well, what do I know? I'm not a Communist.

0-62 in two seconds? I'd like to see the tires that are grippy enough to support that acceleration, especially from the standing start.

Having lived in China, I always take their technical claims with a grain of salt.
On the other hand, for a true sports car that can do more than just floor it and steer straight, or floor it and steer left, there's this electric Porsche:

There's something anticlimatic, though, about the absence of the roar of the ICE.

Konigsegg built a rear-wheel drive ICE V-8 powered car that does the 1/4 mile in 8.54. Fastest in the world.
Yeah, now take away all the computer controls and see how fast a actual human can drive them. Last time I was in a Ducati dealership, the sales guy was mentioning all the new riders buying some Panigale V4 superbike- I said, is that not a bit much for a new rider? Oh no, we have traction control and wheelie control and 5 axis IMU controlling the antilock brakes and etc etc. Hmm.The motorcycles I was raised on and still ride have much less cotton swaddling. If you screw up they will bite. And I like it like that.
The car prolly has traction control and an automatic tranny, but both of those are "old" technologies. Anti-lock brake systems are not new, either--but you don't need those to gofast. Stopping? yah.
But I'm with you: still driving a manny-tranny if possible, no 'eye in the sky' spyware like GM's OnStar. But my car does have anti-lock brakes and it's a '14.
As an electric, it probably relies partly on regenerative braking. One hopes they've done a good job on determining how much current this can pump into the circuitry in cases such as panic-stop from top speed, downhill – and have an adequate safety factor in the circuitry.
(Dorm neighbor in one of the early https://en.wikipedia.org/wiki/Micromouse competitions was was in a group that decided to win by making the robot mouse very fast. They made the energy-density of their 'mouse' as high as they could in order to hot-rod the acceleration.
The test maze had a longer straight run than they had anticipated, and in trying to decelerate from a speed-they-had-never-tested to make the turn at the end, their mouse blew the electronic braking circuit thus leaving them with an uncontrolled 25cm³ cube having the weight of a horseshoeing-anvil and moving at several M/s on REALLY good wheel bearings.
Needless to say, they got a DQ for damage to the maze. The rules did not then specify any additional sanction for other damage to the event space.)
Fair point. I spent Sunday morning on a brake job — pads and fluid flush— on my truck. Ceramic pads and DOT 3/4 fluid are heavy, but they work unless the lines blow.
It's also a lot of MV^2.
