00:00 G'day, I'm Paul. So Hyundai has just released the Envision 74. This is a rolling lap, so it's a
00:06 concept car. They're testing out a lot of new technology within this. Today I'm going to walk
00:10 you around this, but we're also going to drive a one-of-one prototype that basically will herald
00:15 where Hyundai wants to go with hydrogen tech, which has me pretty excited because this is an
00:20 insanely good-looking car as well. Now if you do want to skip ahead to other parts of this video,
00:24 you can use the time codes on the screen, or if you're on YouTube you can scroll down below. And
00:28 if you haven't done so already, subscribe to our channel and press the bell icon. But let's get
00:32 started. Now before we go for a drive and I run you through some of the bits beneath the skin,
00:38 let's talk about the design. So this thing is huge. I wasn't expecting this to be as big in person.
00:44 It's longer than an E-Class. The wheelbase is almost three meters long as well, so it really
00:48 has a lot of presence to it. And the guy that designed this car actually worked for GM and
00:53 designed the Camaro out of Melbourne, so it has a kind of very, very loose Australian connection.
00:58 In terms of the design elements, this is obviously a concept car. This car that you're looking at
01:03 here is, it's a bit of a design buck. There's actually nothing really inside of it, but it
01:07 gives you a clear indication of where they wanted to go with the design language. So you can see
01:11 these pixel headlights here. We've seen a version of this on Staria and also with the Ioniq 5,
01:18 and I think it just really signifies where Hyundai wants to head with LED technology.
01:23 A lot of cooling for this car, and the reason that's important is because it uses not only a
01:27 hydrogen fuel stack, but it also uses EV, so it has twin electric motors on the rear axle,
01:32 and this demands a lot of cooling to make sure that you can access that performance every single
01:38 time. It's rear-wheel drive as well, which I think is pretty cool. Now, come around and have a look
01:42 at these wheels. Obviously this is just the, I guess, the rolling concept car, but the actual
01:49 production car has a proper set of wheels and tyres. I think this design looks really cool.
01:53 If you think of stuff like GT2 RS with the Manthe Racing kit, you have this type of setup
01:59 on the brakes as well, which I think is pretty impressive. Now, have a look down the side of
02:04 the car. This is where you get some of that cooling element. So beneath the skin here,
02:07 you've got a set of radiators there that help sort of cool that whole performance package as
02:12 it's running, and the profile of this car is really cool. So it runs all the way down the
02:16 side there. You can see big gaps in that fender flare that sort of scoop air into the back here,
02:22 and this is where you'll find your two hydrogen tanks as well. Twin electric motors on the rear
02:27 there, so it is very much focused on adding weight to the back of the car there to keep it nice and
02:31 stable. Come around to the back. Okay, now the back of the car. Have a look at this enormous
02:35 wing here. So again, it's all about downforce because when you have that much power and torque
02:39 to play with on the rear axle, you need to keep everything tied to the ground as much as you can.
02:45 More of that pixel LED setup at the back here, and of course no exhaust because hydrogen emits
02:50 just water, so you're not going to find anything down there. Given that you have a battery pack
02:54 and hydrogen, you don't need to have an exhaust outlet there. So where does 74 come from? Well,
02:59 Hyundai created, well, Hyundai designed a car called the Pony Coupe, and this was meant to go
03:05 into production but they didn't have the chassis or the engine for it, but this is where the silhouette
03:10 comes from, and it was a design that actually, I guess, was the predecessor to the DeLorean. So that
03:17 design followed and flowed onto there, and that's where this design has come from as well. So it is
03:22 a pretty cool car to look at, and it just has a real presence to it as well. So next step is going
03:28 to be to take it for a drive. We're only going to get a really brief amount of time in the car,
03:31 but I'm going to run you through as much as I possibly can and give you a reaction of what
03:35 it's like driving a hydrogen-based EV. There we go. Perfect. We good? Adjust it properly.
03:45 Ready? Now we start. Perfect.
03:49 So we've just hit the road in the N-Vision 74. This is one of one, so I'm just trying to be
04:01 as careful as I possibly can because I don't want to damage anything. It is a weird feeling driving
04:07 this because it actually feels like a fast EV. Like it's not really a foreign
04:14 sort of concept. It has stacks of traction, and you can really just get stuck into it. It has
04:23 over 500 kilowatts of power when you have both the hydrogen fuel cell and the electric system
04:30 kicking in. On the back axle, you've got two electric motors, and they're effectively working
04:36 in unison to give you the feeling of an electronic limited-slip differential. It's quite playful as
04:44 well when you sort of really get into the throttle out of a corner. And this is an interesting setup
04:50 because typically you have a single motor on the rear axle. This uses that twin motor setup. It can
04:56 then do things like drift mode, and it can just be, you know, I'm actually just struggling to
05:04 watch here because we are absolutely flying, and it is, yeah, it is just sticking to the road like
05:10 nothing else. So beneath the skin, you've got a battery that's a little over 60 kilowatt hours in
05:15 size, and that's the thing that's giving you that big propulsion. But then what happens is the
05:21 hydrogen fuel stack can kick in and give you almost 100 kilowatts extra. So it really sort of
05:27 picks up and goes nicely. And given this is a prototype, it actually feels remarkably good here
05:34 behind the wheel in terms of being a complete vehicle. It is seriously impressive. So, wow,
05:41 look, this has been a really quick experience, but I've got to tell you, if they can perfect this
05:45 technology where you can have an EV system that works in unison with a hydrogen fuel cell,
05:51 I don't know, you can just do some really cool things. And at the end of the day,
05:55 the only thing you're emitting is water from that whole equation, which is great.
06:00 So we've now gone to track mode. This allows the rear diff to feel, well, I guess the rear
06:06 diff, I keep calling it that, but it allows the rear axle to feel like a limited-slip diff because
06:11 you've got the two motors there. They can then individually control each wheel to give you that
06:15 acceleration out of a corner. So see how that feels as we sort of roll onto the throttle.
06:19 Oh, far out. So in track mode, it's going even harder. It's pinning you back into the seat.
06:32 Far out. It is absolutely moving. And now as I'm getting onto the throttle out of these corners,
06:42 I can actually feel it sort of tucking in as we go. So there is actually an effect there.
06:48 Oh, God. All right. So I know that I talked a whole bunch of gibberish there. It was really
06:52 hard to concentrate not bidding this car and keeping up with the guy in front. So
06:56 it is a remarkable setup. And I think that this tech is really interesting in terms of
07:04 where it's going and what they're going to achieve with it. So I'm excited to try this
07:10 in an actual production car to get a proper feel for it. But here in prototype form, this is,
07:15 I don't know, this is really something else. And I think that they're onto something here. I love
07:20 the fact that this is using so many different technologies and binding them all together
07:25 in such an exciting and fun way. So yeah, that was bloody unreal.
07:29 OK, so I've just finished my lap. I haven't broken the car. They're just checking it before
07:36 other people hop into it. I have a feeling I didn't cover everything while I was driving.
07:40 So I thought I'd quickly run through just some of the key stats. So twin 235 kilowatt motors at the
07:46 rear. So the rear is basically driving cars, rear wheel drive. Over 500 kilowatts when both of those
07:52 systems combine. 900 newton meters, almost a kilonewton of torque. You get torque vectoring
07:59 through those e-motors. So what I was talking about out there was that experience of tucking
08:02 into the corner, getting on the throttle, and then it really just sort of hunkering down and
08:06 pulling it out of the corner. That's the advantage you get with the twin motors. You can't really
08:10 achieve that with a single motor set up on the rear axle. 62.4 kilowatt hour battery, T-shaped
08:15 beneath the chassis there. Again, predominant weight over the rear. Over 600 k's of theoretical
08:20 driving range. So under that little visor at the back there, you've got two 4.2 kilo hydrogen tanks.
08:26 So they give you the propulsion. But in addition to that, you can also charge this through 800 volt
08:32 DC or AC charging. So it means it's just like other cars on that architecture in terms of being
08:36 able to top it up. You can either go down the path of that or put hydrogen in it. What else
08:41 have we got? So the emission from hydrogen is just water. So while the car is sitting there,
08:46 it is just putting water onto the ground, which I think is incredible stuff. During regular driving,
08:51 the battery runs the motors. The hydrogen fuel stack can then charge the batteries. It can act
08:56 as a generator. But under full throttle, the fuel stack can provide a voltage boost. And that
09:00 basically allows you to draw more current from the batteries and send it to those electric motors.
09:04 And the other interesting thing as well is, given heat increases with the square of the current
09:09 drawn, you're able to basically then use the fuel stack when you don't need to use the battery. So
09:14 in these conditions where you're on and off the throttle, instead of just overheating the motors
09:17 in the battery system, the fuel stack is able to then chip in a bit of assistance so that you can
09:22 cool everything down. So seriously remarkable experience. And I'm keen to see where they go
09:27 with this. At the moment, they're saying it's just a concept and it may not ever make it into
09:31 production. But to me, I love this tech and I love that they are thinking about it and not just
09:36 thinking about EVs. I think it is pretty cool stuff. So if you did enjoy this video, please
