Official Lexus Future Product & Powertrain Megathread

Could we see enthusiast friendly powerplants come back?

I mean, we know they're coming back on Toyota models with the new i4s, doubt it for Lexus.

Don't forget if these are global products it'll likely be more affordable to make them all Euro 7 compliant despite potentially lax US regulations.

I assume the EPA will get more relaxed over the next 4 years with their mpg requirements. Could we see enthusiast friendly powerplants come back? Or still full steam ahead on EVs?

100% the former. I guarantee Canada will also start relaxing their laws as well.

The EPA 2027 regulations are already easier on high-end powertrains because the emission limits scale with power (mg/hp-hr). A 1000hp car gets 10x the emissions allowance of a 100hp car. This is to make it easier for pickup trucks to pass new emissions and performance cars benefit from it as a nice side effect. I think this is also why Toyota doesn't seem rushed to updating the V35, as the vast majority of the products using it are sold in US or other markets with much easier emission laws.

By comparison Euro emissions intend to encourage people to buy tiny supermini cars so their emission limits are fixed for any passenger vehicle. In most parts of the world pickup trucks are strictly commercial use so they use different regulations. The EPA rules were made like that because pickup trucks are mostly used as passenger vehicles in US.

Mazda developing new SkyActiv-Z engine to replace SkyActiv-G and SkyActiv-X - to surface in 2027 - paultan.org

Mazda has revealed in its latest financial report that it is developing a new SkyActiv-Z four-cylinder engine that will replace SkyActiv-G and SkyActiv-X when it debuts in 2027. The new engine will use the “lambda …

paultan.org

I guess more and more engines moving forward will be like this, no more fuel enrichment during high load and high rpm to reduce the amount of fuel particulates being emitted out of the exhaust.

Wonder what sort of approach Mazda would take compensate for the power loss from tuning the engine to always run like this. The engine in the 911 GTS T-Hybrid is also like this, and Porsche had to bump up displacement from 3.0l to 3.6l, slap on a bigger turbo and crank up the boost from 19 psi to 26 psi just to squeeze out an extra 5 hp over their previous 3.0l TT flat 6 in the GTS.

The only solution is increasing the proportion of electric power in the hybrid system. Toyota is going to nearly 50% electric contribution in the next generation.

That is not what COO Jack Hollis said.

What he said is that there is not enough demand for BEVs and PHEVs (which is happening right now, causing automakers to change EV roll-out plans), and California's EV mandate would just flood the market with vehicles nobody wants.

He also is asking for a nation-wide rule which would make it easier for automakers rather than having to maintain one inventory list for California and a different one for the rest of the nation.

 

[Flagship1]

I could be mistaken here but this seems more like we dont have enough batteries to go around to build phevs?

September electrified vehicle sales up 22.4 percent; represents 48.4 percent of total sales volume
YTD electrified vehicle sales up 56.0 percent; represents 41.1 percent of total sales volume

Neither the article nor the Toyota COO say that. They say that California's mandate would be "[an] 'unnatural' move [that] would 'limit a customer’s choice'" -- it would flood the market with vehicles that there is no demand for.

Haha, i guess when you contribute the majority of sales you have the most to say.

Theyre the biggest economy and force in america. They nearly single handedly kept the USA relevan through the 2000s.
These "Americans" need to smarten up unless they want the "northerners" who read above a 6th grade level to come down to rural areas and teach civility again 🤣.

Again, i ask toyota your biggest market is literally handing you the phev market dominance...why not take it?

You are obsessed with this but I don't know where you get the idea that Toyota refuses to sell PHEVs. Where's the beef?

Greeting! LE's friends!
2024 Guangzhou Auto Show is being held, and I visited last week, I had talked with staff of GTE (GAC-Toyota Engine).
A disassmbled A25D is displayed on GTE's booth with undisassembled local production M20 Series(M20C/M20F hybrid).

During the communication with GTE staff, I asked about whether domestic engines such as M20/A25/M15C will be replaced by the new 1.5T engine released in June. The staff replied that the current M20/A25 two machines only deal with the current national 6B emission regulations. If stricter emissions regulations are implemented, these machines will be replaced.

As for the local mass production plan of the new engine, it can be learned from the vague answer of the staff that the 1.5T machine will be made by GTE, and the 1.5T may be exclusive to the Chinese market for a period of time, while the new 2.0T engine may still not be implemented domestically, that will continue to be imported from Japan.

But what would that mean for the v35 surely they aren't going to replace it with a phev 2.0l turbo and call it a day. I guess if they don't spend on developing a newer engine the only 6 cylinder option left to them would be mazda but given the stringent tesing land cruiser has to go through they must have tested and developed something to comply with stricter emissions

 

[Randen Montalvo]

This is a dope post. Kudos.

V35 products will only be sold in markets with less strict emissions laws.

National 7 will go into effect 2028-2030, so the 1.5T will probably be 1-3 years later than EU/NA.
