Mercedes-Benz teases ‘highest-efficiency electric car’ with 750 miles range

"This incredible range will be achieved through efficency improvements rather than just a bigger battery pack."

What an interesting statement! "Bigger" – compared to what? A Tesla Model 3 Long Range AWD? That can do around 296 miles (EPA/Highway) – so the Mercedes-Benz will need to be 2,5x as efficient.

The drag coefficient is one area that could be improved. C(d) for the Model 3 is 0.23, which is pretty good for a production car. Lower than that and you are in experimental territory – which is probably how this project might end up for Mercedes-Benz.

Not bad, because these types of projects usually teach us something new. But not good, since this will be another "promise" broken, due to this inflationary PR-approach.

Rear wheel covers? The Lightyear One has 725 km of range and is quite optimized, using only 8.3 kWh/100 km. Mercedes' 1200 km seems like a lot!

Interesting (albeit expensive). I usually take any specs provided by the manufacturer with a grain of salt – including the idea, that you can get 1,2kW/hr of energy from the (static and encased!) solar panels on the roof alone! That seems quite far fetched, to say the least.

Those old automakers are really good at prototypes. They never make it to the road though.

They have perverse incentives - e.g. ICE SUVs and Trucks selling way better than anything else, means no need to invest as much right now in electric aside from high performance scenarios.

I think at the 600 mile range electric cars would seriously start to get tempting. 600 mile range + supercharging (something like +30% charge in 1h) and I'd buy in a heartbeat.

What a bunch of fuckers! "They haven’t disclosed when they plan to unveil the Vision EQXX electric prototype."

Not even a commercial product, a prototype, and they don't know when they'll be able to show it!

What they've been doing for a hundred of years!

I'll buy a Tesla.

well most german car manufacturer have a production ready ev. even mercedes has one, well they were pretty late compared to all others but the eqv is a ev that has a very different market than all other companies.

and if I would have the money I would buy an vw id.4

It could be very high if they started it at the top of Everest and only sold it as going down hill.
