Toyota a few years ago, with inauguration of TNGA-L (RWD-wide) and TNGA-K (mid-large FWD) in 2017, released this diagram, showing all of their petrol powertrains and hybrid motors incoming over the next set of redesigns.
For awhile, I had gotten quite familiar with what I believed to expect in orderly fashion by power output, but then I noticed something.
Toyota says, we should expect 9 Dynamic Force new powertrains and 17 variations. Great question is, what are they?
Toyota per this chart, likely considers the TTV8 as part of the incoming engines above V35A-FTS in LS 500.
V35A-FTS is in a multitude of TMC vehicles in LS, Land Cruiser, and Tundra. Soon to be Sequoia as well
Below V35A family, there is an empty spot there. Was that supposed to be the NX 350's T24A-FTS or a mystery V6 engine, or high displacement I4 yet to be revealed?
Below it is the A25A family, known as the 2.5L I4 in the Camry.
If based on displacement, is this engine supposed to the T24A-FTS in NX 350? Or something else based on output kW, such as the GR Yaris's G16E 1.6L turbo Inline 3?
M20A family, is the Dynamic Force 2.0L I4, which is NA and not FI.
It gets so confusing. Of the 9 petrol ICE engine families, this is confirmed/semi-confirmed so far in order of displacement:
TTV8
TTV6 (V35A)
NA I4 (A25A)
I4T (T24A)
NA I4 (M20A)
NA I4 (M15A)
I3T (G16E) (In GR Yaris)

Is Toyota possibly developing a smaller V6 turbo or NA replacement for 2GR? Another powerful engine above TTV6 (3.4L)?
I posted about this diagram a few years ago. The fellas over at Lexus Enthusiast had a discussion about the powertrains. Trying to figure out what the new 'Lexus work horse' will be to replace the GR series. The conclusion was the new 2.4L turbo.
Between the naturally aspirated A25A and V35A-FTS there is one engine what this forum calls the 'main workhorse engine' (though it kind of isn't), a long overdue replacement for the now over-a-decade-old GR series. Two possibilities exist: the preferred solution is the six cylinder V30A-FTS while the less desirable (but financially more reasonable for Toyota) solution is the four cylinder A25A-FTS. Either design could fit perfectly in the 225-270kW(300-370hp) range, the former benefiting from a bigger displacement and the latter capable of using twin-scroll turbochargers. Regardless of the final choice, this engine is crucial for Lexus' performance models.

I think the two engine choices below the 2.0L are the M15A (1.5L) and I assume an upcoming M18A (1.8L). GR Yaris uses the G16E-GTS engine code and I can't find evidence that it's a Dynamic force engine per se.
Between the 2.0L and 2.5L should be a 2.0 turbo, which could receive a fairly heavy workload as well since it could go in many models here and abroad. Current 2.0L turbo in the NX300 is the 8AR-FTS engine.
The two above the 3.5TTV6 are still unannounced. I think it's safe to say one was a TTV8. The other I'm not so sure. Maybe a NA version of the rumored 4.0L V8, but I can't see that being feasible, even back in 2017.

Lexus had mentioned there are other F cars coming. They also said there will not be any V8s in any car under 100k (if I recalled correctly).
So if there is going to be a new ISF or RCF and it won't be V8 then the only known engine that could be a possibility would be the 3.4TT.
The current output of the 3.4TT wouldn't be competitive although I am sure it could be tuned for more power. What I think, apart from the other engine likely being the V8TT, could the other engine be a inline 6 TT? There was always a rumor about Mazda developing a rwd chassis and inline 6 to share with lexus...although i believe Carmaker1 said this isn't true? (Correct me if I'm wrong).
Nothing really makes sense why there is 2 engines above the V6TT and these plans probably have already changed.
yeah I know but even back in 2017. I see no need for them to have an engine slotted between the v8tt and v6tt.
Unless they were planning to do a LFA rebirth.
We'll never know. Unlike other automakers Toyota/Lexus have always been good at keeping their cards close to their chest. That is one thing they do well and it drives media and enthusiasts crazy
Since the company is an a expert in making durable engines, I would have liked to have seen Toyota/Lexus attempt to make a rotary engine with durable/reliable apex-tip seals for the rotors....the mechanical Achilles-heel of rotaries. The apex-seals are the equivalent of piston-rings in conventional ICEs...they seal the tips of the rotors against the inside of the rotor-housing as it spins....and that is also one reason why a rotary uses oil as well as gasoline in the combustion process. No manufacturer seems to have been able, as of yet, to produce a rotary with seals that can last as long as conventional piston rings that are installed correctly. Mazda, to date, has produced most of the rotaries, but a few have also been developed by other automakers....mosly for experimental use. The Mercedes C-111 was one of the most well-known outside of Mazda.
