Is there still literally nothing else we know about the 4IS even in Sept 2019? Will there be a 2020 IS as the last model year of the 3IS? This wait (and lack of new info) is killing me.
It has been pretty tight lipped....

One likely thing to happen is for Toyota to adopt its (wardauto) award winning UX/infotainment in the RX to the 4IS and other models. Rather than getting criticized mainly for the current infotainment systems, at least, critics can focus on other elements of design or car features.

Just imagine planned obsolescence disappearing with CA/AA compatibility and future-proofing with next gen battery technology in the 4IS.

Daimler halted development of all future ICEs and will only focus on electric power. No more update to future Mercedes engines. They realized they are woefully underprepared for the electric revolution. Unfortunately for them switching to full electric right now is a path to disaster and a competitive hybrid needs a super efficient ICE which they don't have.

The hard truth is that TM3 is eating mid-size sedans for breakfast and the IS will be DOA if it doesn't launch with a competitive full-electric model.

Looks like the 2020 IS is showing on Lexus.com. Anybody with info on what's different between 2019 and 2020? The info on the website is so curated and controlled that it's really hard to tell what changed. I know the powertrain is still the same though.

We’ve got to give it to Elon, he really managed to put an entire industry in hyperdrive to BEV’s!

Maybe before Tesla a hydrogen car would make much more sense than now with the current state of battery development, but it’s still very good for us (the costumers) to have all of this choice and different technologies pushing one for the other.

So, only for MY2021 a new IS in the best case cenario?

^ I think so.

The problem I see is Toyota is bent on using the E-TNGA platform for the upcoming 10 electric cars (6 global models and 4 likely for China) by 2025 but the newer Lexus vehicles will be on the TNGA-L so now I'm kinda doubting that the 4IS will come in a BEV variant unless the holy grail of BEV -- battery technology -- makes leaps and bounds before 2025, permitting vehicles on the TNGA-L platform to be customized as BEVs.

@internalaudit , I want to believe it’s possible due to CHR has been announced as a BEV and it’s built on ‘normal’ TNGA’ and we even have a very good indication as the UX being the first Lexus BEV and it’s also ‘normal’ TNGA...

What we can see it’s how big of a deal the next couple of years will be for Toyota and specially Lexus due to several Model changes.

Almost every car maker now talks about getting many of their BEVs out by 2025. Even existing battery makers such as CATL is predicting lots of progress on current Li-on technology:

and many newer solid state batteries kinda have the same target but we know Toyota will announce its own SSB progress next summer.


Good thing my horizon can stretch that far, thanks to owning a Toyota and two Honda vehicles and because we know depreciation is the number one pocketbook killer and I can probably scoop up used BEVs (if need be) for a song if Toyota and Honda delay their BEV offerings to Canada. :)

There are no trademark filings for the next generation IS, so does this mean that like the case with the ES 350 and ES 300H that IS 350, IS 300, and IS 300h carryover with no power train changes for TNGA?

Nearly all new vehicles from Lexus that change Powertrain required trademark filings by Toyota attorneys 2 to 3 years beforehand. We are in late 2019 so by now they should have done that. I know now that the car is definitely not going to be a 2023 or 2024 model. According to a trusted member of this website at least for the United States it is one year away.

In the case of the 6th generation ES you had trademarks filed in December 2010 21 months ahead of launch. For the current generation, ES 250 was filed recently in July. That could easily be for a model year 2021 introduction, yet nada for IS.

Infiniti pulled something similar, the first model years of the Q50 still used the VQ37VHR engine, then they switched to the 3.0TTV6 for the 2016 MY.

True but at this point this should not be happening. The 2GR FKS needs to be replaced in such a vehicle and a better Dynamic Force 4 cylinder needs to replace the A25A immediately. Nissan at least maintained that engine for only 7 years and updated it from the original VQ35 before that (w/gradual increases). The 2GR has only increased 5 hp since 2005, 14 years ago!

Maybe the lack of trademarks doesn't mean anything, as once upon a time Toyota MC barely filed trademarks in March 2000 for the LS 430 that already made its debut at NAIAS 2000 and other 430 nameplates in GS 430 and SC 430 that month. Typically they would've been filed in 1998 or 1999 ahead of fall 2000 and March 2001 launch.

IS 300 was already trademarked in November 1997, ahead of July 2000 launch (IS 200 came earlier). Maybe it's about keeping it close to vest or indecision on how to market a new powertrain. It does happen.
