0:00A car that rolls on the ceiling, jumps
0:02over stationary cars in a loop, and
0:05then gently lands on the ground in a
0:07perfectly controlled sweep. Tesla
0:10pushed the staging of its new sports
0:12car, the Roadster, very far. But behind
0:14this American-style show that is
0:16supposed to amaze us, several questions
0:18remain unanswered, and you will see
0:20that the subject goes far beyond the
0:21simple presentation of a new electric
0:23car. So how does this roadstore work?
0:27What is it for? What is its promise?
0:30Will these technologies be applied in
0:32production cars, and will they really
0:34be available one day? That's what we're
0:37going to see in this video, in which I
0:39will answer all these questions and
0:41many others precisely because this
0:43presentation impressed me but also left
0:45me with a slight aftertaste of being a
0:47complete joke, I won't hide that from
0:49you. And stay until the end because I
0:52will explain to you why some of the
0:54comparisons that I saw after this
0:56launch don't hold water for a second.
0:59And just to clarify, this video is not
1:01intended to be a Tesla bashing, but
1:03rather to examine the facts in the most
1:06objective way possible. For those who
1:08don't know me, I'd like to remind you
1:10that I personally drove a Tesla for 5
1:12years and loved it. Let's get started.
1:20First, let's recap the early days of
1:22the Roadster project. We'll quickly go
1:24over the first Roadster. The first
1:26version came out in 2008 after Elon
1:29Musk bought Tesla, and it was the first
1:32Tesla and the first electric sports car
1:35based on the Lotus Elise. The vehicle
1:38had already caused a sensation at the
1:40time, allowing a few wealthy
1:41Californians to show off in what was
1:43the first production electric car. Then
1:47Elon Musk presented what was called the
1:49Roadstore 2 in 2017. A superb electric
1:52sports car promising extraordinary
1:54performance and autonomy, with hints
1:56that this car could be equipped with
1:59rocket propulsion and that it could fly
2:01. At the time, no one really believed
2:04it. At this presentation, the official
2:07release date was announced as 2020.
2:09Many fans confidently placed orders,
2:12paying a deposit of € 50,000. 9 years
2:15later and following numerous promises
2:17that were constantly pushed back, the
2:18Roadstore 2 still hasn't been released,
2:20and the suckers who paid a deposit are
2:22disappointed. But there's finally
2:24something new with the presentation on
2:26October 15th last week, where Tesla
2:28unveiled a profoundly different car
2:30with a new design, new ambitions, and a
2:32new deadline. This time, we're talking
2:35about 2028. In the meantime, the
2:37electric sports car has discovered
2:39abilities that bring it closer to its
2:41boss's space program. You've probably
2:44all seen the video. A car climbs a ramp
2:46until it ends up upside down, then
2:48performs an aerial maneuver before
2:50landing on its wheels. All without a
2:53driver, as part of a demonstration
2:54whose preparation and organization left
2:56us a little lost. It must be said. With
2:59this new version, the curves of the
3:012017 prototype give way to an angular
3:04body, strip lighting signatures, and
3:06doors that open upwards. The influence
3:09of the Cybertruck can be seen in this
3:11geometry, with something of a
3:12Lamborghini that has been through the
3:14Tesla design office. Personally, I much
3:17prefer the 2017 version, but each to
3:19their own after all. At the rear, a
3:22large movable spoiler on the lead
3:23covers several openings, some of which
3:25look like exhaust outlets. The height
3:27of irony on an electric car is that it
3:29is actually a cold gas engine that
3:31allows the car to accelerate in ways
3:33that would be impossible with a
3:35conventional engine, even an electric
3:36one. The video mentions four versions:
3:40a basic version without the most
3:42extravagant features. Then the
3:44performance thrust and rocket versions.
3:48The first one remains quite
3:49undocumented for now. The other three
3:51correspond to a progression ranging
3:53from active aerodynamic support to a
3:55thruster capable of moving the car
3:56through the air. It is clear that some
3:58features depend on the configuration
4:00and, of course, the region in which it
4:02is sold. We imagine that there will be
4:04very few regions in the world that will
4:06be able to sell the Tesla rocket. First
4:09, how does the car stay on the ceiling,
4:11but Malarie? Well, it's quite simple
4:12and it's not that new. It uses fans to
4:15extract air from under the bodywork.
4:18Skirts close to the ground maintain a
4:20low-pressure zone, a bit like suction
4:22cups. The difference between the air
4:24pressure above the car, the gold plate
4:26on the ground or against the ceiling.
4:28In fact, the car is simply equipped
4:30with a giant vacuum cleaner that
4:31presses it to the ground with enough
4:33support to exceed the weight of the car
4:35. Driving upside down becomes
4:36physically possible on a suitable
4:38installation. Of course, you can
4:39perhaps have fun driving in a tunnel
4:41upside down, but it will be a little
4:42complicated all the same. As I said,
4:44the principle is not new. It even dates
4:47back a little since it had already been
4:49introduced in Formula 1 with the Brabam
4:52BT46 in 1978. More recently, the
4:54MacMury Sperling, this small British
4:56electric single-seater works on the
4:58same principle with performances
5:00equivalent to this Tesla Roadster.
5:02Tesla would thus use a known solution,
5:04aiming to integrate it into its own
5:06sports car. The announced time for the
5:09performance is around 1.6 seconds from
5:110 to 60 km/h, which corresponds to
5:13around 1.65 seconds for 0 to 100 km/h.
5:16For use on a circuit, the logic is
5:18quite convincing on the road, but it
5:19raises more questions. How does the
5:22system react to bumps, potholes, debris
5:24, and road irregularities? How is the
5:27skirts worn? How can noise and rear-end
5:29projections be limited with the fan?
5:32The second version, the frost version,
5:34would add rear-wheel drive powered by
5:36pressurized nitrogen. According to the
5:38specifications reported in the video, a
5:40200-liter tank would contain more than
5:42100 kg of gas, around 690 bar, which is
5:44still a lot of pressure. The thrust
5:46then complements the thrust of the
5:48electric motors without depending
5:49solely on the grip of the tires or the
5:50resistance of the tires. Tesla thus
5:53announces a 0 to 97 km/h acceleration
5:56in less than a second. However, this
5:58capacity would have a fairly concrete
5:59limit. The thrust mode would last 3 to
6:025 seconds and then the gas reserve
6:03would have to be replenished, which
6:05would take around 6 to 7 hours, which
6:07would put the possibility of launching
6:09rocket-style launches into perspective.
6:11Added to this are questions about noise
6:13, the protection of people nearby, and
6:14the resistance of the device in the
6:16event of a collision. We can easily
6:18imagine the Rogue version pushing the
6:20exercise even further with six
6:22additional thrusters oriented in
6:23different directions and an additional
6:25400 L tank that occupies the passenger
6:27space. The roadstore would therefore
6:30become a single-seater with a 0 to 100
6:32announced at around 0.7 seconds and the
6:34famous acrobatics. To give you a
6:36reference, a Formula 1 car does 0 to
6:38100 in around 2 seconds in the best
6:40grip conditions, or even a little less.
6:43And a Formula E, the electric Formula 1
6:45in 1.7 seconds. This version would be
6:48accessible by invitation only and would
6:50not be allowed on the open road. That's
6:52for the spectacular and, let's say,
6:54completely lunar side of the
6:55presentation, or rather Martian in this
6:57case. But it's the more classic
6:59characteristics of the machine that
7:01really interest us. The video reports a
7:03target mass of less than 1,700 kg,
7:04which is not bad for a car in this
7:06category. A carbon fiber body and two
7:09motors that drive only the rear wheels.
7:12While the 2017 version offered three or
7:14four motors, the power would be around
7:171,000 to 1,300 horsepower. One thing
7:20that really surprised me was the choice
7:22to make it a rear-wheel drive at a time
7:24when the most efficient electric cars,
7:26including Tesla's, generally use € 4
7:28motors. In terms of autonomy, it's a
7:32big scam, we can say, since it would
7:34ultimately be only 480 km while Mosque
7:36had promised nearly 1000 km during the
7:39first presentation in 2017. The
7:41charging power could reach 500 kW from
7:4315 to 80%in 10 minutes. Nothing too
7:47crazy in 2026 when we see what brands
7:49like Denza and Byyd or others are
7:51offering today with flash charging from
7:5410 to 97%, so almost 5%in 9 minutes or
7:56from 20 to 80%in 5 minutes. So much for
7:59the technology. Now the question that
8:01everyone asked themselves apart from
8:03the Transit fan boys who would have
8:04applauded anyway even if Mosque had
8:06presented a new adjustable wrench. What
8:08is it for? This is the first thought
8:11that comes to mind once you get past
8:13the pits of the kenote and these
8:15somewhat surreal images. In fact, the
8:17answer is neither rational nor
8:19pragmatic. It is first and foremost a
8:21demonstration, a demonstration of
8:23technology, of know-how, and also the
8:24demonstration that we can always dream
8:26higher, further, and stronger. In this
8:29sense, the bet has paid off, and we
8:31have to admit that we have witnessed a
8:32pretty crazy thing that consists of
8:34making a machine fly in a controlled
8:35manner that was absolutely not
8:36originally designed for that. A machine
8:39with no A, no rotor, no rudder. A kind
8:42of anvil in fact. Which somewhat defies
8:45the laws of aerodynamics and lift, and
8:47which makes it closer to a rocket than
8:49an airplane. So the logic is quite
8:51respected in the end. Then, regarding
8:54the real usefulness, we have to see if
8:56all this technology could be integrated
8:57into everyday cars and for what purpose
8:59. Honestly, I don't see any, except
9:02perhaps thrusters that would improve
9:04acceleration without draining the
9:06battery and wearing out the tires, or
9:08to boost the car on a hill to improve
9:10its range with small boosts. Regarding
9:13the suction system, apart from
9:15ultra-sporty driving and therefore on
9:16the circuit, who really needs a car
9:18that is glued to the ground? I don't
9:20really see any. Then, we're talking
9:22about innovation. But what innovation
9:23are we talking about? I personally
9:25don't see any. A flying car, that's not
9:28true. The Roadstore doesn't fly. It's
9:30not a flying car. It's a car that jumps
9:32a few meters off the ground for a few
9:34seconds before reaching solid ground.
9:37And gravity can't be fought like that
9:38with a few thrusters capable of
9:40operating for only a few seconds. So
9:42there's no innovation on that front.
9:44Aviation has existed for a century,
9:45rockets for over 60 years. And if we
9:49want to talk about flying cars, or
9:51rather flying personal transport
9:52vehicles, I suggest you look at Xping
9:54and other Chinese manufacturers who
9:56already have operational machines, in
9:57the process of being approved in
9:59several regions of the world, which are
10:01capable of transporting two to four
10:03people over several hundred kilometers.
10:06Regarding the vacuum that presses the
10:08car to the ground, as we saw, it
10:10already existed in 1978. Then, we can
10:12debate the definition of innovation.
10:15Yes, putting rocket boosters on a car
10:16can be seen as an innovation.
10:18Personally, I see it more as a
10:20demonstration without any real
10:21practical application. In this case,
10:23you could also put boosters on an iron,
10:26a lamp or a lawnmower. But why do it?
10:29Now, on a more down-to-earth note,
10:30there remains the basic version of this
10:32roadster which will therefore be a
10:33classic electric sports car. All this
10:35with many quotation marks, without
10:37boosters or vacuums. An attractive car,
10:39which will certainly already be
10:41extraordinary to drive, but which will
10:43arrive on a market where competitors
10:45will have already grabbed a good part
10:47of the cake, like the Denza Z, the
10:49electric Porsche Caillement which will
10:51arrive next year, or even the new BMW
10:53M3 and Mercedes AMG GT. Even if the
10:55latter two are a little less exclusive
10:57because they are not hybrids and,
10:59needless to say, the cake of electric
11:01sports cars is very small and we are
11:03really on a loaf. Then, I saw
11:05comparisons with other launches that
11:07took place during the same week, or
11:09even the same day. Quite strange
11:12comparisons, for example with the new
11:13electric 2014 and with the new Porsche
11:15Mission S. So, let me tell you that
11:17these parallels are quite irrelevant,
11:19not to say completely out of place.
11:22First of all, nothing works for the
11:242014. Not the same use, not the same
11:25budget, not the same audience, not the
11:27same narrative. We could even say that
11:29they are all opposites. I'm not
11:31specifically defending Citroën, and I
11:33even teased them a bit in my previous
11:35video, but honestly, being sarcastic
11:37about the supposed innovation of the
11:39Roadstore by comparing it to the 2CV is
11:41completely irrelevant and shows that we
11:42don't know much about the automotive
11:44industry and marketing. And you know
11:47what? There will certainly be a lot
11:50more electric Horsepower sold than
11:52Roadstores and it will certainly bring
11:53in a lot more money for Citroën than
11:54the Roadstore will bring in for Tesla,
11:56perhaps even in terms of image. On the
12:00Porsche Mission S. Then, yes, the car
12:01was presented on the same day as the
12:03Roadster. So it went a little unnoticed
12:05. So how could that possibly cause any
12:07problems for Porsche? We're not talking
12:09about the same product. The Porsche is
12:11a combustion model, for a different
12:13clientele and different use. Porsche is
12:16aimed at a wealthy clientele of car
12:17enthusiasts and enthusiasts of the
12:19brand. People who prioritize the
12:21pleasure of driving over the bluff of
12:23gas-powered vehicles who couldn't care
12:25less about flying cars. At worst, they
12:27travel in private jets and have a
12:28different philosophy about cars than
12:30the Twitter geeks. Now, I admit it,
12:33it's a shame that this Mission S isn't
12:34electric because it would have really
12:36ticked all the boxes. The remaining
12:39issue is the schedule after the
12:41postponements of the first project,
12:43from 2017 to 2020 and then 2026. The
12:44new deadline isn't really reassuring,
12:46especially since Tesla included a small
12:48clause in its reservation contract
12:50stating that the brand does not
12:52guarantee the delivery date, or even
12:53that it will ever happen. They are
12:56still very strong. For people who have
12:58been waiting for years, does the car
12:59they reserved still correspond to the
13:01one Tesla intends to produce? As we
13:03know, the roadstore ultimately occupies
13:05a special place in the brand's strategy
13:07. Tesla has therefore found a way to
13:09rekindle the conversation and, above
13:11all, the buzz around its products, even
13:13if we still wonder about the true
13:14relevance of this roadstore and whether
13:16it will really come out one day in
13:17these four versions. It also raises
13:19questions about what Tesla is really
13:21becoming and whether in the long term
13:23we will still be able to consider this
13:25brand as a purely automotive brand
13:27given its expansion into robotics and
13:29now even into aerospace. In any case,
13:31those who fantasize with so much
13:33certainty about the famous Model 2, the
13:34small Tesla supposedly planned in the
13:36brand's boxes, are out of pocket. It is
13:39confirmed that the project never
13:40existed other than in their dreams. And
13:42without false modesty, this is
13:43something I have been saying for years.
13:45We will see if the future proves me
13:46right or wrong. In any case, I
13:49recognize at least that Tesla and more
13:51broadly Elon Mosk have a talent, this
13:53ability to make the impossible possible
13:55and therefore, in a way, to continue to
13:57make us dream. And for that alone,
13:59whatever one thinks of the character, I
14:01say hats off to the artist. There you
14:03have it, I hope you now know a little
14:04more about this new Tesla Roadstore. If
