December 2023 story.
linky Lamborghini Developing Active Camber and Toe Control to Improve Handling Lamborghini's Active Wheel Hub adjusts camber and toe on the fly, and we experienced it on the Hurac n on the test track. "According to Rouven Mohr, Lamborghini's chief technical officer, this is one of the final frontiers of vehicle dynamics. Suspension geometry is usually based around a set of compromises, with the loads created by a car in motion inevitably negatively affecting at least some of these. And the alignment settings that are right for the track will cause premature tire wear on the street, which is why many high-performance cars have track-alignment settings and necessitate switching back and forth. Gaining active control in two different planes toe being the angle of the rotating wheel relative to the direction of travel, and camber its side-on angle relative to the ground means that many of these compromises can be eliminated. The results, based on our drive in a Lamborghini Hurac n development mule at Porsche's Nard test track in Italy, are deeply impressive. The system works exclusively on each of the Hurac n prototype's rear wheels. Active toe control is, in essence, a rear-steering system. We've had those before, of course but this one can also move the wheels between toe-in, where the leading edges point very slightly toward each other, and toe-out, where they do the opposite. In very general terms, toe-out makes a car more reactive and keener to turn, while toe-in gives better high-speed stability. Active camber control is more revolutionary. Under cornering loads, a car leans over and the suspension compresses, which alters the relationship between the tire tread and the road surface. On something as low and firmly suspended as a Lamborghini supercar, the effect is much slighter than it would be on a 1970s sedan, but it is still significant, as it creates uneven pressure distribution on the tire's contact patch, which reduces grip. Many performance cars are set up with negative camber (the tire leaned in on its inside edge) to compensate for this, but doing so reduces straight-line traction and increases tire wear. The Active Wheel Carrier's ability to adjust it according to load is in effect a "have your cake and eat it too" solution, allowing the tire to generate up to 25 percent more cornering force, according to Lamborghini With Active Wheel Control activated, the difference is immediate and obvious. It feels as if the rear axle has gained significantly more grip. The prototype immediately finds more traction in slower corners, but it also feels much more stable at higher speeds and in faster turns. The actual changes being made by the system are slight, especially to camber. Talking to Mohr reveals alterations are normally only fractions of a degree, with multiple corrections each second. But the effects are profound, and with AWC working, this aged Hurac n feels like a different car. " |

I believe the print version of this article said the prototype with these hubs was 3 seconds faster (lap time) than the same car with stock hubs. Cool stuff

Mercedes (I think) was running a manual version for a short while (until the FIA caught on) a few years back in F1. Hamilton could change the toe in/out by pushing or pulling on the steering column, in order to change the handling dynamics for cornering versus straights. (Edit: I think it was mostly to save tires; could have a more aggressive alignment for cornering while cornering, which would normally eat tires in straights, but then you could straighten it out as you’re exiting, and have no adverse tire wear)
Obviously this automated version makes much more sense for everyday drivers versus professionals, but cool to see a similar concept reaching consumer products. |

There's a bunch of toe control, HICAS/Super HICAS, Honda 4WS and other mechanical. ZF AKC system which is more sophisticated, and Audis DAWS, which this may be an outgrowth of.
Huh, half a mil by '19, didn't realize. VAG has pushed predictive modeling (used in Quatrro Ultra), and here expands LVDI (Lamborghini Dinamica Veicolo Integrata) its on board control suite, to actively manage, predictively, rear suspension orientation, in two axis. Kinda different than mechanically levering through a limited arc. The practical result - 55-75 second reduction in lap times. Which, given other constraints, is very significant. But more so it's a marketing lever, that differentiates in an increasingly competitive segment. |

Anyone know if Lamborghini offers anything like Power 15 or Main Power 15? When extended Power Warranty came out about a decade ago, tho varying usefulness, certainly seemed a solid marketing move by Maranello. LaFerrari Power is only what $30k? I've never much explored Tratorri, so curious. |

With how well electronic steering has been since they started putting them in road cars the tech is finally mature enough to start using it for suspension adjustments. In theory this should mean the car would never need an alignment once it's calibrated

My best friend and his brother had been go cart racers since they were about five and transitioned to asphalt racing cars in high school. I used to like to go over to their shop and see what they were working on. They had all of the standard engine stuff that everyone wants to see; you know dynos and horsepower.
However his specialty was suspensions and after high school he went to VA Tech to become an engineer and then went to work on Winston cup teams as a suspension specialist. He used to say that it matters less how fast you CAN go than how slow you HAVE TO go that matters. You have to spend less time going slow. On a straight track, horsepower matters, but if you have to turn, the suspension is everything. He was fascinated not only with suspension geometry and vectors, but the importance of bump steer and how the angles change under loads. The problem was that everything is a compromise and the designer has to make decisions about the conditions he wants to optimize. Very deep and important stuff. If i were buying a high end supercar i would care less about overall horsepower and more about handling. The ability to not have to compromise with just one setup is an awesome advancement. |

I'm really excited about the trickle down, to where we might get such one day. Peeps are missing some important aspects of what's been done here. This isn't a purely a mechanical setup. It's not a selectable setup, nor is it merely limited to toe. AWC dynamically changes alignment (nearly 7 degrees of toe either way), in two axis, to optimize suspension orientation, 60 times per second, based on sensor inputs and predictive algorithms. The AWC system moniters data from a number of sensors including steering angle, throttle, and g-forces to add or subtract camber and toe independently at both rear corners. The outcome was dramatic according to the OVERDRIVE YouTube channel, journalists testing the car improved their lap times by 4.8 seconds, and Lamborghini's own test drivers saw a 2.8-second reduction in lap times when AWC was on. More recent write up. https://www.hagerty.com/media/driving/lamborghini-unveils-trick-active-alignment-setup/ It's not ready for prime time either, but still cool. Next Panarama goes live with "Active Ride" - so this stuff is going production. Nothing is getting less complex.  The all-new Porsche Panamera is ridiculous! V8 Turbo vs V6 driving REVIEW 2024 |

I'm not sure anyone had a production system previous. There's been 4WS at Lamborghini for over a decade as someone mentioned earlier. |

Cars that keep themselves in optimal alignment??... I am just a few years from retirement so not worried... Man when this crop of good alignment guys go we are fucked. I'm hardly exaggerating. No kidding and that goes for the whole automotive sector not just alignment guys. Right now there are still guys that know how to do shim alignments,work on carburetors ect. All that knowledge will be gone in ten years. |
