lol banned F1 technology..like rims bigger than 13”, ESP, ABS, etc.
Soon it’ll be more reasonable to make a list of what is allowed instead. This is why F1 is going downhill and costs so much. The organisation only allows 30-40 year old technology while any kind of creativity is greeted by a shotgun. This is why F1 is such a costly nightmare in my opinion, the only way to gain an edge is to perfect old technology to the finest detail. If creativity was allowed perfecting details would be ridiculous. Sure new tech is costly, but it’d have to be developed for roadcars anyways.
we can weld it xD
Believe it or not, my 2004 Golf mk5 XD uses the same technique to mimic a front limited slip diff XD and I can even feel the rear inside wheel braking when cornering hard (btw it’s just the ESP system helping with cornering :)) So when VW uses it, it doesn’t want to spend on a limited slip diff but when Mclaren uses it it’s cool technology? the world is weird.
same do pretty much every non-M BMWs since 2008 (year might be wrong but i know the 1-series have this system ever since they were released)
So do Subaru on the newer models rear diff, I have heard.
There is a difference between fwd golf and rwd Laren
it’s a solution to a problem that literally shouldn’t exist…
All I hear is shorter brake life.
Carbon ceramics.
Correct me if I’m wrong, but in order to use the trick of braking the inside rear wheel to aid turn in you’d need an open diff. Using the analogy of a locked diff, applying the brake to inside wheel will also brake the outside wheel (as they are directly connected) discounting the desired effect completely. In the case of an open diff this wouldn’t happen and you will end up with greater torque at the outside wheel because the inside wheel is being held back (as explained in the video) and therefore simulating the non-50/50 torque split created by an LSD. With an open diff and this tech, not only does braking one wheel create a yaw rate (imagine coasting along then applying one brake - the car will turn even if the steering wheel is straight) but it also increases the torque at the outside wheel adding to this yaw rate when power is applied.
Indeed, and this is a technique used by EDL’s since at least 20 years now on various cars, and becoming more and more common, especially on FWD’s. Sadly, it has multiple downsides, one being high brake fade and very low control over the lock’s rate (lock being efficient only when brakes are cool enough to provide desired friciton). On a P1 obviously there is no problem, but on an Alfa Romeo, BMW or Audi, it does provide some help but doesn’t replace a real mechanical solution unfortunately.
Few differences there though. There are 1.5 LSD and 2.0 LSD. The 1.5 way diff only locks under acceleration while the 2.0 diff locks in both acceleration and deceleration. Ive owned cars with both. The 2 way diff is by far the hardest as while turning in it can cause the outside rear wheel (RWD) to slip and loosing you stability. Good for drifting bad for a daily car. The McLaren open differential is a little special as sensors read the diff rpm and each wheel rpm and adjusts grip accordingly through braking. The BMW M3 does something similar called ESC where it uses the brakes to keep the car straight in a slide where McLaren also went one further and use the individual wheel brakes to help turn the car. But what do i know right???????
I would like to add, that I can not imagine a good driver even considering adding throttle at corner turn-in point. So, basically, the single rear braking function is there to turn the car in only by braking, not by shifting engine torque. It does shift engine torque later on mid corner and exit phase.
I have this on my 2001 330ci, but its terribly clunky and just results in choppy cornering and massive power cuts. Id take an LSD any day and a lot of people get them installed. However im sure mclarens is 100000000x smoother. (sorry for double comment, i posted this as a reply as well)
In the Laren, it just eats the brakes. I am not fond of this solution. I maintain, that brakes should be used for braking only. But I do get the necessity. This is the only way you can shift torque left to right without extra parts.
Seems like the McLaren CEO loves the 1 tyre Burnout #OPENDIFFFORLIFE
Lotus loves open diffs too.
Yeah but… why??
A solution to a problem that doesn’t exsist
The real question: “How’s the burnout?”
You see 900hp so….imagine a burnout similar to the bmw m5 with the slip differential. It mens that it is not that crazy the burnout cause 900hp are really too much just for the tyres- drift car
