Mercedes Claims Electric EQXX Concept Will Get 1,000 KM of Range

There are generally two ways to increase the range of electric vehicles: pay for a larger battery, with more capacity, or make the EV use less power.

With the Vision EQXX, Mercedes-Benz is taking a big stab at the latter, creating a concept, it believes will be able to exceed 1,000 km, on a single charge, without resorting to an oversized power cell onboard.

The target for the EQXX, is power consumption of less than 10 kWh, per 100 km.
For reference, the Tesla Model 3 Standard Range Plus is rated to consume 14.8 combined, and Benz's own EQS 450+ estimated at 15.7.

Mercedes points out that 10 kWh is enough power to run a tumble dryer for three hours.

Using tech from Formula 1, Mercedes-Benz says it has "squeezed the energy of the EQS into the dimensions of a compact car." This means 100 kWh, in a pack that is 50 per cent smaller, and 30 per cent lighter, than the one found in the EQS.

It's connected to a drive system that reaches 95 per cent efficiency, in power use, from battery to wheels. The total power output, to move the car, is a respectable 201 hp.

Good luck sailing Australia's coastline without auxiliary power... off the QLD coast the Great Barrier Reef gives you a minimum of 2,300kms of lee shore in the most spectacular sailing waters in the world... an area of over 340,000 square kilometres.

Sailing the length of the reef without power almost guarantees you will not complete the trip.

I doubt any insurance company in the world would insure a cruiser in this area without a motor of some sort.

It is significant that Mercedes Benz concedes that Tesla is the car maker to try and catch up to when it comes to EV's.

Tesla is 10 years ahead of the rest of the market technology wise... and in 10 years time, Tesla will still be AT LEAST 10 years ahead of GM, Ford, Volkswagon and Mercedes etc.

Easy, you ban the sale and or manufacture of ICE cars. No cars no use. Then you simply restrict the use of older ice cars.

Then there gone , no enforcement needed.

NIH indirectly funded research in Wuhan. That’s not in dispute. https://www.nih.gov/about-nih/who-we...-cov-2-origins

What’s in dispute is whether “ gain of function” research was undertaken using these funds. This is where the dispute starts.

quite amazing though that the USA effectively funded research in Wuhan.

The key deliverable on cars is the ability to make them. Ford made more Mustangs in its first year of production then Tesla did in 6 years.

The major advantage the big motor companies have is they know how to build lots of cars quickly.

There’s really nothing in Tesla’s kit bag technology wise that the majors don’t have access to. Mercedes vision and autonomous tech is widely regarded as better then Tesla , but Mercedes simply don’t make wild claims.

Porches Taycan is far superior to the model S , S can’t sustain its acceleration multiple times Taycan can. Porches electric engineering is way beyond Tesla.

If you sit in a model S it’s a far inferior cabin to high end Audis etc.

Having to drop three menus down to open the glove box is not “ 10 years ahead “

Tesla will fade from view, as the majors complete their transition to all electric production. Tesla will drown in the competition . It’s the Lotus of electric cars.

Once you have the hydrogen, how can you store it?

…...

Hydrogen from water is currently something in the vicinity of 35% efficient. The theoretical limit is somewhere around 60%.

The only place hydrogen might become a regularly used fuel is for long range aircraft using cryogenic storage. There are too many better alternative electro-fuels for other uses.

... but how many mustang ev's did Ford make in 2021?

... OK, so sell your Tesla shares then.

In my opinion Tesla 4680 battery technology, and what it spawns, will bring electric propulsion much closer to powering water craft economically.

Think Hydrogen is actually the answer, yes it’s terrible at efficiency.
But the mining industry runs on diesel power for the electricity, and on a boat it’s not the power available from the battery but the recharge time. and the same goes for long distance driving, and for the marine sector as well, batteries are just not a realistic possibility.

Good question.
But, what can/will the competitors do, in the near future [since that's what this thread is about]?

“Ford Building More Mustang Mach-E EVs Than Gas-Powered Mustangs”
So far in 2021 [Jun 7], the production numbers are clear: 27,816 Mach-Es and 26,089 gas-powered Mustangs.
The ICE Mustang still outsells the Mach-E by around 3 to 1 in the U.S., but that's not the case in EV-forward places like Norway.
➥ https://www.caranddriver.com/news/a3...as-production/

“Ford to triple production capacity for the all-electric Mustang Mach E by 2023"
Ford said in November that it would increase its production capacity of electric vehicles to 600,000 units globally by 2023 — a goal that would be spread across the Mustang Mach E, F-150 Lightning and commercial E-transit vans. If Ford hits that 600,000 figure it would double the number it had expected to produce over the next two years.

Tesla Model S Goes 752 Miles [1,210 kilometers] with a Prototype Battery from a Michigan Startup
Our Next Energy Inc. [ONE] retrofitted the Tesla Model s with it’s “Gemini” battery, holding twice the energy of Tesla's original, while fitting entirely within the same space, providing nearly 90 percent more range, than its original 402-mile EPA figure
It's a proof of concept, for the company's own future battery design.

So what does sailing UMA have in terms of
1) Total weight of batteries and propulsion?
2) what’s the range under power alone?
3) Solar panels both wattage and surface area?
4) cooking via?
5) Heating Via?
6) assuming no generator so no Petrol or diesel, is that correct?
Just interested in the subject

From memory, Uma has:

1. 12 x 100Ah Battleborn LFP so 14.4kw, 20Kw electric drive say 200kgs in total.
2. Probably 30-40 miles at 3-4 knots, assuming no input from solar.
3. They have about 800w.
4. They cook via microwave, induction hob and two burner alcohol stove.
5. Heating via wood burner or shorepower.
6. They took a Honda 222i to Svalbard just in case which is a sensible precaution. They have petrol on board for the outboard.

You mean Panasonic battery technology

I don’t own Tesla shares , Tesla will fade from view , it’s the COMPAQ of EVs , it’s was first to market with an innovative concept. But the big auto makers know inherently how to build cars.

The Hyundai range is a far better range of cars taken as a price performance engineering point of view. The New Ionic 5 is a fab “ ordinary “ car. VW evs are very good too ( if a bit pricey )

Nothing in electric cars is high tech. It’s actually a very simple product to build , flashily A4 user interfaces are not “ tech “ it’s just flashy marketing.

I have a lot of contacts in the automotive industry as I used to design automotive robots. The big car companies will pick up the EV cudgel and beat Tesla with it. Companies like VW group have forgotten more about building cars then Tesla know about the whole subject. Fact.
