Official Lexus Future Product & Powertrain Megathread

[internalaudit]

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 the cons out weigh the pros thus Torsen & eLSD all the way or in BMWs case a TVD that is coupled with a more balanced chassis and more power.

The most important part is you enjoy what you have and with that enjoy. Im happy Lexus provided a TVD & a Torsen to its owners.

Cheers!

Their postponing/delaying it thats very interesting! Good read!

I guess the IS gets to live a little longer if this is true.

I wasn't talking about the RCF as I didn't mention that specific vehicle in my last post as we all know that has the Torsen differential (optional TVD in the past).

I guess my argument about track times made sense to and resonated with you because the advantages TVD or Torsen diff imparts are not enough to win races, there's more factors to track times than just added traction and control, and even over and beyond driver skills or it would be the same driver winning, race after race.

I'm not complaining that Lexus vehicles don't have these advance differentials. I can always take my business elsewhere. I'm just one consumer and Lexus couldn't care less what I want. Lots of potential choices out there. TVD wasn't very common anyway but I think it will be available on more vehicles the next few years.

Perfect. Maybe it will come with performance solid state batteries.

Postponement likely to coincide with battery strategy and waning interests in expensive EVs that are not that much better than ICEVs or HEVs.

Update:
Oh, this will come with the performance batteries.

Oh, I guess Toyota is pushing out its battery implementation strategy half a year out. I think even if the roll out is delayed by one year, no one is really going to care as long as the batteries are superior to what's currently available in the market.

Curious on how this eventually translates to the consumer product love these lines.

It seems like where brands are struggling globally toyota is strategizing their different brands and still making bank. I mean lexus isn't globally doing so well aside from the US and the lineup reflects that cause there is an onslaught of cuvs and suvs. Also toyota as a whole isn't invested in elctrification as much as lexus cause aside from western countries others aren't interested in evs well aside from china anyway so they are just using lexus as a test bed and a halfway point just in case someone decides to enforce strict emissions standards they have something respond and their delaying tactics are more than likely due to them knowing the market won't respond well rather than resource issues cause if that was the case they would be struggling with hevs which for most parts of the world they aren't so going foward we might see a lineup like this
- toyota branded cars
- crown lineup (global lexus replacement more or less)
- century (ultra luxury)
- lexus (relevant to a few countries mostly America)

I totally don’t like it. Redeeming quality is that it is not another CUV.

If it looked like the current IS with some modifications, a redesigned tail lights, it would be be great.

That long rear tail light seems to only look nice on all Porches and Lexus SUVs.

 

[Randen Montalvo]

After watching the "LF-R" track footage i wonder if the engine is a stroked 5.4 2URGSE with a hybrid assist. Anyone have better info on it?

 

[Falcon]

Wrong. Lexus is the hottest luxury brand in the middle east.

I guess the IS gets to live a little longer if this is true.

Isn't it supposed to get 1 more ICE/HEV generation before going fully BEV?

yaayyyyy we have dinosaurs! :^)

I am with you. I realize it's a concept and we need to wait to see what the production car looks like, but the IS has been one of Lexus' best looking vehicles in every generation, and one of the most attractive vehicles in its class as well.

If Lexus scraps the IS legacy for some sort of weird electric "part coupe, part CUV" blob with no personality, that'll be... um... not great.

"Not great" is an apt descriptor for Toyota's handling of Lexus these days.

Whenever I see Lexus floundering I just look at upcoming stuff for GR and Toyota to make me happy lol.

 

[Randen Montalvo]

Facts, TMC def could use some more push with again engaging Lexus i agree, i wish i was excited about GR stuff but folks like myself didnt leave M cars for Toyota branded GR compact sports cars. I do hope to your point TMCs breathes more racing life into F as they did when Yaguchi san was active. Lets see indeed.
