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.

“I never believed in the unsprung weight is bad theory in the first place.”
It does have some affect as does the additional rotating mass.
Ford has shown that with the GT350R.
Rotating mass is a separate issue, and depends on the moment of inertia. Which is less of an issue with electric hub motors, vs stupidly huge and heavy wheels and tires.
The discussion was about unsprung mass and ride.
When Jaguar moved the inboard brakes to the rear wheels for the XJ40, they were surprised that the ride improved.
For me, larger mass with same spring rates gives lower resonant frequency and absorbs a greater range of higher frequency vibrations.
“When Jaguar moved the inboard brakes to the rear wheels for the XJ40, they were surprised that the ride improved.”
I never heard of that.
True R G LeTourneau did that eons ago in is moving equipt.
Will they have fancy meaningless commercials with loud music to sell this crap?

Electronic controls do the hard work.

“I have a copy but it has disappeared form the internet”
The article discusses the development of the whole rear suspension, not just moving the brakes outboard.
“Like in an Osprey.”
Like in every modern car.
Moving the brakes is covered in the article.
“Moving the brakes is covered in the article.”
No doubt. How did they quantify the effects of moving the brakes?
Your home has a 11KW charging station? That’s the requirement.
60A 2 phase breaker in the service box, 6 gauge 4-wire to the outlet. Most electricians won’t install the outlet box unless it’s OUTSIDE the garage in case your lithium ion battery bomb lights off and they don’t want to be sued.
If you only have 100A service to your house that means don’t run your dryer, your electric stove, a well water pump and most other high current loads while your EV is charging. 11KW is nearly 60A.
That’s a real nice freedom enhancer right there.
“Most electricians won’t install the outlet box unless it’s OUTSIDE the garage in case your lithium ion battery bomb lights off and they don’t want to be sued.”
It is just an outlet. The electrician has no liability for how it is used.
Just like the electrician has no liability for the space heater that causes the house to burn down.
“If you only have 100A service to your house that means don’t run your dryer, your electric stove, a well water pump and most other high current loads while your EV is charging. 11KW is nearly 60A.”
NEME6-50P is 50 amps. Charge at night when you don’t use the stove or dryer.
“Your home has a 11KW charging station? That’s the requirement.”
Level II chargers plugged into a 40 Amp circuit will run at 32 amps (NEMA 80%). That is 7.8 kw.
The put it on a rolling road with slats to create horizontal and vertical shake, then measured the accelerations on a dummy seated in the back seat.
I’m retired, and drum brakes are a regression.

What do drum brakes have to do with this topic?
“The put it on a rolling road with slats to create horizontal and vertical shake, then measured the accelerations on a dummy seated in the back seat.”
Are you referring to Jaguar? That test would not quantify the effect of just moving the brakes. It would quantify the effect of a whole suspension/drivetrain redesign.
In the paper they said they tested moving the brakes to the wheels with the old suspension, before they changed anything else.
