BMW and Continental announced a new strategic partnership to develop a in-wheel motor, including an integrated brake. The strategic partner is electric drive Munich-based start-up DeepDrive, renowned for creating the first radial flux twin rotor motor with power electronics that can be used in production vehicles.
DeepDrive is an expert in creating energy-efficient electric motors and has produced large-scale automobiles for many years. Matthias Matic, president of Continental’s Safety and Motion business area, said they have gained a great partner as electric motors created by DeepDrive help to improve the range of EVs. Additionally, they are lighter, more inexpensive, and more resource-efficient.
With the help of existing investors UVC Partners and Bayern Kapital with its Bavarian Growth Fund, DeepDrive raised a total of €15 million in its Series A financing round. The company’s stated goals with the additional funding are to begin industrial production of the engines and to expand its workforce.
Furthermore, DeepDrive says it already works with eight of the ten top automakers and plans to introduce its technology to the market in large-scale production by 2026. The firm says its objective is to continue meeting the growing market demand.

Ever since it became likely that EVs would go this route, there has been various revisionist studies suggesting, hey, unsprung weight isn’t so bad after all.

Turns out Woke unspring weight has completely different physical effects from bad old IC unsprung weight / s
In a fundamental way, the Deconstructionists and Post-Modernists are correct when they claim there is no real truth content in any of this “Science” and it is just Narratives of Power... etc.
“For me the question is you’d need to make sure they are perfectly in sync with the other wheels or you’ll get serious torque steer just driving normally.”
Electronic controls do the hard work. They even modify power to each wheel based on diving conditions. Present SCS use the brakes.
Today’s EV WonderInvention is………..
“Turns out Woke unspring weight has completely different physical effects from bad old IC unsprung weight / s”
That study was not woke. Old fashione ICE car.
Like in most EVs, yes.
That’s an already solved engineering problem, fortunately - synchronizing several electric motors, especially brushless motors, is a common practice these days.
“...various revisionist studies suggesting, hey, unsprung weight isn’t so bad after all.”
LOL...such a typical lib reaction, isn’t it? “We’ve changed our mind and XYZ isn’t so bad after all.”
Exhibit A: Racism.
* You’re white, we cannot admit you to this university.
* You’re white, we cannot award you this professorship.
* You’re white, you cannot fly our planes.
* You’re white, you cannot swim in this pool.
* You’re white, you cannot come to our Christmas party.
* You’re white, you deserve to DIE.
“oh, like in a Tesla.”
Tesla is years ahead of other production auto-makers. The Tesla Cybertruck is really a test platform for their newest technology, which will go into their $25K model next year. In-wheel motors, steer-by-wire for each wheel, 48v ethernet wiring, etc.

“Elon Musk reveals plans for Tesla Cybertruck 4-motor variant”
The real negative is the extent to which extra weight in the wheel assembly affects the amount of time the wheel is in contact with the ground on a bumpy road. Apparently that is not a big effect.
I’ve been saying ever since Tesla came to be that the hard part of the electric car isn’t the electric, it’s the car. And it the mainstream auto mfgrs weren’t going to sit idly by and let Tesla take over. Once they got serious about it they would make electric cars with better electric than Tesla.
They work in giant earth moving machines. Might have trouble with high mile cars.
“That study was not woke. Old fashione ICE car.”
I guess you missed the second sentence in the first paragraph where they talked about “in wheel motors”. ie. electric motors.
Not to mention that the study was done for Protean ELECTRIC.
“In a wide-ranging study connected to feasibility studies for in-wheel motors, some specific and detailed measures for the sizes of the effects in play have been taken - and the reality is something of a surprise compared to what “everybody knows”. Subjective, Objective and Predictive measures of ride & handling suggest that the modern development toolbox is easily capable of restoring dynamic performance and that the opportunities afforded by in-wheel motors...”
“The real negative is the extent to which extra weight in the wheel assembly affects the amount of time the wheel is in contact with the ground on a bumpy road. “
How about electric motors being subject to continuous vibration and shock loads same as the hub, wheel bearings... etc.
I want to see the durability testing results on this nonsense.
The problem with EVs is the battery problem including charge, weight, cost and charging time. In every other way the technological advantages are enormous.
[hint, you get power in your house because the stuff works really really well and is incredibly reliable. Trains work for the same reason.]
electric motors in your house are stationary, and train tracks are somewhat smoother than the vibration loads from roads.
This is the typical durability test for rough roads. I want to see the electric motor that survives that for 100,000 miles.

The capacitor combined with the flux allows the car to transport you to the future.
“Not to mention that the study was done for Protean ELECTRIC.”
Done on an old fashion ICE car. I see you do not question the study.
Lots of unsprung mass...
Not with 28 mph top speed and range of a Radio Flyer wheelbarrow.
I never believed in the unsprung weight is bad theory in the first place.
