Mercedes-Benz EQXX 1,000 km
Mercedes-Benz raised eyebrows with the design of the EQXX, a study that closely previews a production model whose main traits are its low weight, aerodynamic efficiency, as well as taking energy from the sun to go further than comparable EVs. When the automaker revealed the concept, it announced that it could do over 621 miles (1,000 km) on one charge.
Well, now it has demonstrated that it can actually achieve the number by driving exactly 626 miles (1,008 km), averaging a truly remarkable 8.7 kWh/100km, which equates to 7.14 miles/kWh. However, there is more to this, since Mercedes says the EQXX still had juice for an additional around 87 miles (140 km), after it had been driven basically non-stop for some 11 hours and 32 minutes...
For reference, the longest range version of the EQS electric sedan flagship, the 107.8 kWh 450+, is conservatively rated by the EPA at 350 miles (563 km), although an independent test by Edmunds has confirmed that it can fairly easily pass the 400 miles (643 km) mark; in the same range test, the EQS recorded an average consumption of 29.5 kWh/100km, or 3.39 miles/kWh.
With that in mind, the EQXX’s achievement (and the fact that it still had plenty of range left after the test) is even more impressive and it really shows that all the clever innovations that Mercedes has integrated are working. Between its very small frontal area (just 2.12 m² or 22.8 ft²), low drag coefficient of o.17, relatively low weight of 1,750 kg (3,858 pounds) and the 117 solar cells on its roof, it is considerably more frugal than the EQS.
It is worth noting that the photovoltaic array doesn’t actually add electricity into the main battery pack, but the 12-volt battery instead. Through it the car runs auxiliary systems, like infotainment and climate, thus allowing the car to preserve the charge from its main battery pack (whose size is not known for the EQXX).
It was so slow, the hitchhikers turned down rides.................
I wonder how much wattage is coming in from the solar panel? Hard to imagine it being more then 500 watts (with at best 5 peak solar hours in a day that's 2.5kWh). For reference, the Mach-e gets 2.4 miles per kWh. Even with the BMW topping that at 7.14 miles/kWh, I guess an extra 20 or so miles.
I guess it better be all that and a bag of chips with the yuge cost.
55 mph (621 miles divided by 11.3 hours).
...and it only takes three weeks to recharge the batteries.
Looks like a BMW Roundel on the hood.
Same with my wife’s BMW Z4...............
Which is still pretty good.
Thank You I was just going to ask about heating and cooling.
ANY use of heater, air conditioning, etc substantially reduces the mileage. We just drove from Sacramento to La Quinta and back. Air conditioning on most of the time. Witnessed high end electric SUVs plugged into charging. It took us a few minutes to POUR energy into our SUV. The electric SUV owners did not look too happy waiting, and waiting, and waiting. If they used the ‘fast’ charge, does the manual have a warning that it cuts into the total life of the battery?
“How long to charge it?”
How old are you?
Or driving in the Rockies.
48+ hrs ?
ACCESORIES ARE ON A DIFFERENT BATTERY SYSTEM...............
Big whoop, I will never want or drive ANYTHING electric on any roadway.
Pretty cool, but there isn’t enough cobalt, lithium, and rare earth metals for everyone to get an electric car. But then, the eco-nazis don’t want you to have a car.
So after 400 miles, how long did it take to recharge for the next 400 miles?
On road trips, I commonly drive 1,000+ miles in a day, just stopping to gas up, grab fast food, and keep rolling.
Thats a real nice Beemer you got there! at least it looks like an Isetta
Wind resistance goes up with the square of the speed. I suspect it would be a lot more than a 10% reduction in range.
there’s the rub!!
