Honestly, this looks like something out of a movie. I kind of hope it's real because it's an amazing stunt, even if it would be impractical in real life. Knight Rider come to life.
Bose did the same thing many years ago and I've wanted a jump button in my car ever since. This car looks incredible!
I'm holding out for the far superior jump jacks that Speed Racer had.
Yes, that is a problem I face so often. It’s a wonder nobody else has thought of that. /s
That is really cool. I wonder if they need sensors for the ground ahead to make that work. The response on the speed bump was very impressive.
They have another demo video where they demonstrate driving on 3 wheels by balancing the car using the same complex suspension set up.

I just wouldn't jump the car at that speed!
That's cool! I can't tell if it has enough clearance to do that with a tire on, but it would be nice to have a limp home mode if you got a flat. Although I suppose if you own this car and have a flat, you probably call a car to come pick you up and then have your people take care of it.
Wait, wait, how does it work? When front right wheel is absent and car turns left, what kind of magic prevents the car from tilting? This car can move center of gravity somehow to the rear, or center of gravity already in the rear?
Just thinking off the top of my head, they might lower the rear opposite side to pitch the nose up a little as well as soften the rebound, raise and stiffen the rear same side to provide clearance, and then modulate the front opposite side to balance the weight of the car as it shifts? I have no real idea but thats the best thing i could come up with.
You right probably, also rewatching the video, car turning looks actually slow, it's camera movement that makes it feels sharp.
That's just standard cultural appropriation. Lowriders have been 3-wheelin' for decades.
For the last one, I'm imagining that they built the car for the worst of my redneck neighbors who'd rather jump their car over the trans flag sidewalk that step on it.
Was that meant to be a hazard in the video or just coloured dust?
I don't think it had any meaning beyond colored dust looks cool when kicked up by a car going 120kph. I initially thought it was to show how the car won't even smudge it, but that's obviously impossible even for a car as sleek as that one.
Yeah this. At first I also found it strange but when the cloud popped up, it was obviously just to make a cool cloud. Rainbow colors probably just made the most vibrant effect, not everything is a political statement.
imagine catching the gays, horrible when that happens, yeet that car over it! /s
Lol. For the number of small towns against it in my dumb province, you'd think that they see it as "cooties"
Who's the snowflakes now :P
Hah oh yeah - they've always been the snowflakes, only it's the sad child inside that's begging for attention with them rather than the reasoned adult asking for recognition in a free society.
I think it was meant to look cool by pulling a cloud of colored dust, as well as if you missed the jump you'd definitely see the chalk tire tracks.
With the kind of down forces that tail wing (?and front hood?) are generating at high speeds, I have to wonder how high that car would jump if it did the same 'hop' standing still... (spoiler: good thing it's unmanned).
Also, I'm calling bs on it (unless maybe it was travelling at a far slower speed than the impression the video gives).

This is what it looks like jumping standing still:

It looks like they're popping the nose up first so I would think they should be getting a bit of lift on the front end. As for the rear wing, it looks fairly level like its not setup for big downforce if any.
Lift is no joke btw.
Ignoring aerodynamics (which I am also not an expert in), I don't think I'd want to be in a car going fast when it jumped over something; its asking for trouble.
Would be fun to watch a physics engine simulate that car hopping an obstacle while car was on a curve
I've played Crazy Taxi before. I know how this goes.
Ahem. The jump button wasn’t introduced until Crazy Taxi 2.
Sorry— I just couldn’t participate in this thread without upholding my Sega nerd cred.
Lol, judging from how enthusiastically a few of us added Sega tunes to that VGM thread yesterday, I practically expected it 😁
I think just a bit of uneven pavement would be enough to throw it. Or anything other than that perfect track.
Today I got onto the topic of air travel with my son and he asked why airplanes can go so much faster than cars. I said, "cars have to drive on roads and roads suck."
It was being tailed by the camera drone. Can those fly so fast in such a controlled way? I know basically nothing about drone photography so maybe the answer is “of course they can” but the thought gave me pause as I was watching.
Drones can have an unbelievable level of control/precision, especially in a scenario like this where it's highly controlled and rehearsed. It wouldn't surprise me to learn that they had the entire path of the drone pre-programmed in advance. With both the car and drones being remotely controlled, you have a considerable level of control over the timing.
I think some of the high end drones can also path relative to a target identified on the camera or relative to a beacon, so it might have a series of pre-programmed moves relative to the car itself. Some of the human operators are very good too, though, so who knows.

I love how something about the way it's edited to look cool just screams "Chinese" to me. It has a similar visual language to the clips I've seen from Chinese movies. Not to hate, but it just looks like lame editing (or maybe it's partly the cinematography?) on a cool video. Just a difference in aesthetics between different markets.
Can anyone explain why we need or want this kind of functionality? For safety, racing, or just for fun? I can't imagine it being very safe to deliberately catch air over small obstacles on public roads.
In this case, it’s just a demonstration of the functionality, probably involving software tweaks. It’s a way to show off what BYD is capable of in re suspension.
Sure, but what is that suspension capability for? What kind of practical/useful functions are implied by this? Just wondering. I'm not really a car person.
The four independent suspension corners can act in conjunction with enough force to lift the whole car off the ground. That means they can also catch the car without it scraping (on a perfectly flat surface) and likely absorb most any bumps you encounter.
In other words, it's a marketing stunt, but unlike every other manufacturers' ad which is usually either a heavily modified or even CGI model car, with a big asterisk for professional driver on closed course, this is allegedly an unmanned, unmodified car.
This doesn't excite 'car people' mostly because it has no 'practical' uses. It's cool. This might excite Forza Horizon fans, since that's likely the only racing game to model the jump ability, and TikTok/YouTube stars who will rent it on Turo for their video doing 90mph in a school zone.
However, an active suspension can allow you to raise the car for a steep inclined driveway and then lower it when you get to the highway for better down force. Hydraulics, Air Bags, etc, all forms of active suspensions for different use cases.
I wonder if this is the main function it will have what with a lot of the people with enough money to buy this in China living in highrises or going to shopping centres with basement parking down sometimes quite steep ramps.
For sure it's not safe to be driving that fast anywhere but a race track. I think it's just to show off how capable their suspension is.
