Interesting. Some claims seem exaggerated. The inventor has an excellent track record in biomedical innovation and entrepreneurship.

Certainly interesting.

How do you measure a gain in "handling performance", I wonder. They claim 15% and 29% for different versions.

Yeah - certainly won't be +29% lateral grip!

It looks very interesting but I guess the same question as the Lotus Active comes to mind, how much power does it consume vs any fuel savings.

 

I would imagine the forces it has to aply to alter teh inboard mounting point of a suspension link are quite high in big SUV. 

 

And I supose an obvious question what is teh fail sfe default if it malfunctions - although with modern electronics tha may be an ode of date concept!

It'd be nice if there were a competitive racing environment—a pinnacle of motorsport as it were— where ideas like this could be tried, and claims tested and quickly evaluated in a setting that couldn't easily be manipulated for the purpose of fleecing investors.

The power consumed would be minimal - the forces are high but the displacements required are very small.

 

Pretty confident these guys aren't scammers. They have a history of successful high-end engineering innovation. https://www.sciencei...18newinnovators

Active toe is obviously easy to prototype given we've got EPAS. I'm not convinced mass production cars would need active camber, the gains are slight. Active castor is captain crazypants.

Agree that active castor would be all cons and no pros.

 

Have you considered that active camber would allow the designer to optimise suspension (and steering) geometry - freed from the need to consider kinematic camber change?

 

I have suggested elsewhere that the ultimate suspension might be one where each all four wheels were steered and cambered independently - under electronic control. We already have torque vectored to each wheel independently, likewise bump in a fully active suspension.

 

There you are - 4 of the six axes at each wheel under electronic control - the remaining two (lat and long displacement) remain fixed for obvious reasons.
