Newest update: What I posted before may be wrong and IS is all-new on a TNGA platform. I don’t know which platform, but that’s what I was told more recently. I think 2GR is carryover though.

Y’all can light me on fire now.
whew!!! (relieved)

Thanks for the update we can't blame you Lexus has been slacking lately. my hope is we get concrete information about the power trains that will be on offer before I pull the trigger on the RC-F. Last thing I was told is the next IS will be done properly (fingers crossed)

Now that we can all dream again with a all-new IS, my powertrain wish-list would be:

->2.5L A25A-FXS Hybrid as a IS300h
->2.5L A25A-FXS PHEV as a IS400h(?! I don't know what to expect since "e" it's for electric... Maybe capital H?)
->3.5L 8GR-FXS as a IS500h
->TT V8 as a ISF

2 of them are already sold on the Crown, on GA-L... An IS-BEV seems asking for too much...

I hope it looks good. Also hope there is an IS 500h. But IS 300h will probably the only engine in Europe.

Although I would like a BEV for my next car, I think I will be extremely satisfied with a sporty enough AWD IS hybrid car as long as it can do 0-100 in 6 seconds or less, get 50 US MPG, have a touch screen CP and AA infotainment system and hopefully have torque vectoring ( but highly unlikely since only non-hybrids have the Lexus TVD or Toyota torque vectoring).

On a side note, I watched the above acceleration video for the 2018 Toyota Crown 3.5L Hybrid (8GR-FXS) and I'm shocked at how fast it can move; it does 0 - 100km/h in 4.7s. I wouldn't mind at all if the next gen IS was on a similar TNGA platform with that engine + 10 speed auto + AWD.

Never mind the V35A-FTS twin turbo V6, put that 8GR-FXS in with 354hp and you can have your cake and eat it too.

Any chance this will be a PHEV?

The 2021 RAV4 PHEV will do 0-100 in 5.8s. I think it only needs to lose weight, height and have torque vectoring to surpass the current IS300h performance.

Current 300h performance is...well...adequate (?) for a sports sedan... 0-100km/h:
6,2seg -> RAV4 Prime
8,1seg -> RAV4 HSD AWD
8,4seg -> IS300h/Rav4 HSD 2WD
8,9seg -> LandCruiser V8 TurboDiesel/ES300h

So, a IS Prime with the exact same powertrain would be killer. This being said, I'm starting to get really curious about what's coming...

I already stated my powertrain "wish-list", but, when I think about it:
->A25A-FXS/PHEV, it's a FWD powertrain, would they made it RWD with longitudinal engine just for one car?
->8GR-FXS, it would touch the heals of the big brother (LS500h), even Crown's size it's quite bigger than the IS (GS size), would be a lot of fun a IS500h...

Hoppefully, they won't turn IS to FWD... Even this redesign/new platform debate, all option makes sense (financial/technical/offer)...

I always loved the IS, every single iteration of it, even being as old as it is I still think why I'm waiting for something better when it's so uncertain if there will be another sports sedan (BEV/PHEV even more uncertain) at current prices (It's cheaper than a UX...)

Same here. I will wait for the 4IS specs, what BEVs will be available out there (and their pricing) and see if I have to revert to picking a used 2017+ (includes adaptive cruise control) 3IS350 AWD F Sport. We don't have the 300h here in Canada or even the States.

Double wishbone front suspension on the IS is a plus, except when it comes to suspension repairs and replacement. We have it on our 11 Accord coupe and it handles decently well on stock tires/suspension. Only found out about the advantages after going through a few youtube videos such as this. Most race cars have either double wishbone or some multi-link set up up front.

FWD IS, no need to bring it, the ES covers both IS and GS in that case.

A turbocharged I4 HEV or PHEV would be enough if no V6 HEV (500h). Of course nothing can be more reliable than IS XE10 or XE20 with 3GR-FE, but Lexus still does fine with high-tech, not that I am interested in it. I wish cars came with just electric windows and mirrors and a/c. Don't need more.

I’m expecting to see what’s coming up, but a Atkinson cycle engine does have lower exhaust pressure which isn’t a good thing for turbochargers... Miller cycle perhaps makes more sense?

Tell me all about it. My 02 Civic is my daily driver and it doesn't even come with power mirrors or windows and the a/c compressor just died last summer (it was already replaced a few years ago). It doesn't even have ABS and comes in manual transmission. Engine and transmission reliability (some suspension components about to give due to age and neglect) are paramount to me. That's why I would rather get a nice Lexus for my next car.

I know in a newer car I want better safety features like higher crash safety rating, electronic stability control at the very least, but auto high beam and BSM? Just turn the high beam on when necessary and adjust the side mirrors so there is very little to no blind spot and of course shoulder checking will be helpful too.

Most interesting/useful normal car for me. Can't wait to see what it gives.

A lifted wagon version (a la Audi Allroad), called IS SportCross, is too much to ask for.
