Official Lexus Future Product & Powertrain Megathread

BMW uses eLSD instead of TVD.

100% to either rear wheels sounds like TVD to me. Older BMWs did come with LSD. LSD is max 50/50 and that's not how the M Sport Differential is described.

You can check BMW's description on its configurator page. Code is 2T4. It's standard on the M340xi, M240xi, X3 M50 and other M-lite products and you can find the description is of a TVD and not a LSD

I already said in races the tracks are perfect and weather is usual permitting.

I seriously do not expect the best race car drivers to beat traction afforded by TVD in inclement or bad road conditions. Sure, it's doable by maybe the top 2% of drivers.

Drivers cannot control traction as well as a computer can. Sure they know when the mass shifts but tell me how they can control distribution of torque between wheels or even between front and rear?

Race car is almost perfect driving condition where traction may not be the most important factor to win.

The point is Torsen less weight better track performance and times then TVD heavier weight worse times.

For weather issues a predictable read end is easily controllable. I guess if you never been on track never done performance driving then sure TVD helps and is for you. I can agree with that. It makes it easier for people to drive the car.

My point is better track time doesn't mean better traction and control, which is what TVD is for.

I think that's what's confusing you and a few others.

You are pointing to racing , where ultimate traction and control does not necessarily guarantee winning. Lots more elements/factors than just those two. I can think of luck, brashness, strategy (like maybe blocking cars behind).

I never claimed TVD allows for the fastest lap times. I don't even care about lap times as I have no intention of tracking. I said I want TVD because of its benefits of imparting maximum traction depending on how the vehicle is traveling/moving.

To me at least, there's no point shelling out $60K or more on a vehicle with an open differential. That's like 19 century technology? TVD is like a $1500-3,000 option and doesn't break the bank account.

Ahh if its not about track times or performance on a track. I shall exit out of this convo. I am solid on why Lexus removed it.
I do however appreciate its use case in adverse weather and i think thats its biggest benefit.

There is a reason on TVD cars you have a "SNOW" button lol.

Note: A Torsen is not a Open Diff you may want to correct that , Whereas an open differential always has to split it's torque split 50/50 between each wheel, the Torsen differential is capable of directing a greater percentage of torque through one wheel depending on the ratios of the gears.

Two different things my friend That is probably why where all a bit confused here with your traction framing is kind of confusing sir.

Note the LFA has a Torsen LSD and is praised for its handling and newer cars many opt for eLSDs and avoid the penalty of TVD provides its just the way things are going performance-wise. For adverse weather i would say TVD makes total sense over a eLSD or a Torsen but for track performance wise the cons out weigh the pros thus Torsen & eLSD all the way.

The most important part is you enjoy what you have and with that enjoy.

Cheers!
