Rendered: The Next-Generation Lexus IS Sedan


Renderings of the next-generation Lexus IS are a favorite of the Japanese automotive press — this attempt by (a currently unknown) magazine was posted yesterday by a Lexus fan on Instagram:

Lexus IS Rear Next-Generation

The differences between this photochop and the existing model are minimal — the only changes are with the front and rear bumpers, making this rendering seem more like a mid-cycle refresh. That said, the design of the current IS sedan has never been a weakness, and maintaining some consistency across generations would not be a bad move.

The magazine mentions a 2021 release along with some preliminary dimensions:

Lexus IS Dimensions Next-Generation

Compared to the current model, the next-generation IS length and wheelbase would grow by 4cm, with all other measurements staying the same. Also mentioned is a 2.5L engine with 181 horsepower, which makes absolutely no sense and I’m choosing to ignore.

Maybe I'm thinking a little too simplistic here, can't they slap in the TTV6 from the LS into the IS as an IS350 successor and voila? Then a V8 for the IS-F again? Upgrade the turbo 4-cylinder to have better NVH and a slight increase in power/torque? Lastly implanting the genius multistage hybrid system for a hybrid model?

An IS 450 makes perfect sense to me. IS 350 should NOT be the range topper anymore. Either a detuned V35A-FTS or a 3.0L Dynamic Force TTV6. ISF V8? Nah. It will be V35A-FTS or similar with added improvements.

I had been looking forward to replacing my G35 with the V38 Q50, but since that car just got Ghosned, I’m very interested in the next IS.
Most important want: stick to the GA-L rear wheel drive platform! If one is going to pay extra for a luxury/sport sedan, it should be the real deal, not a gussied-up Camry or Altima. Toyota doesn’t seem to have the management or financial issues of Nissan, so hopefully the IS won’t suffer the same fate as the Q50.
Other wants: make F Sport a real competitor to M Sport, Red Sport, etc.; not just visual and suspension upgrades. The days of making a 200hp entry level car, 300hp top “normal” car, and a 400-450hp bonkers car to fight the M3 are over. Bonkers is already 500-ish hp, and we’re talking about three years from now. There’s a hole in the IS lineup now.
Styling should be more aggressive than the LS or ES, but too much. A sport sedan should get its looks from good DNA (restart RWD platform rant here). To me the 2IS nailed it.
Apple CarPlay and Android Auto. Smartphones are no longer a fad, and automakers with few exceptions, are bad at making UIs. People are gonna use their phones, automakers should concentrate on how to safely integrate them, not replace them.
My two cents, FWIW.
Well, thank you. I appreciate that my man. Here is an early look at a proposal by designer C. Lee from 2016 for it, at Design Centre Atsugi in 2016. Things have wrapped up now, with major changes along the way. This was during ideation sketching.

Well I think it makes sense to skip 300 directly to 350. With 260 and 300h at the bottom, a 300 won't make much sense in EU or China, while it will be underpowered in the U.S. when competitors move up to the 200kW/270hp class by then. Also with a 2019 debut, would they even bother with the 2GR-FKS, an engine near EOL?

A 450 will only happen if they want a mirror image of the 43AMG-Lite/63AMG duo strategy. So it will become a V35A-FTS (doesn't even need to be detuned, competitors will be in the 300kW/400hp class in 2020) and a V35A-FTS hybrid duo?

One thing they could take advantage of is the compactness of the V35, which allows a front-mid layout. This leaves enough space to put a pair of torque-vectoring motors in front of the front axle, making the next IS-F AWD with electric boost.

It is difficult to know what the IS should be if we don't have a full image of the Lexus model portfolio. Before sportscars could be had in all sizes and prices, now only in big size with a lot of power and high price - prestige (GT86 and MX5 exception). Same thing might be (is?) happening with sedans. Ironically Mercedes, BMW and Audi make A Class Sedan, 1 Series Sedan and A3 Sedan, but we should remember China is the driver here. For how long?

If lexus plans to upsize the IS, that's fine, as long as they keep the weight as low as possible.
I've always been a small-car guy and opted to keep my 2nd-gen IS as opposed to replacing it with the longer 3rd-gen. Nonetheless, I see the Chinese writing on the wall. In the West, the Lexus IS is no longer the rear-legroom runt of its class, a position taken over by the Cadillac ATS and the Jaguar XE. But ATS and XE either already offer stretched "L' versions in China or will do so shortly. Lexus IS, on the other hand, doggedly sticks to a single shorter wheelbase.

The (TN)GA-L RWD architecture has, thus far, been released in 3 wheelbase lengths:
2870mm (113") for Lexus LC
2920mm (115") for Toyota Crown Concept / upcoming 15th-gen Crown
3125 mm (123") for 5th-gen Lexus LS

Conventional wisdom would've suggested a continuation of the Toyota Crown / Lexus GS platform relationship dating back to the original Toyota Aristo. With the GS now out of the picture, though, will the 4IS step up to the Crown platform-mate role? I certainly think so. Coincidentally (or not?), the Lexus LC sits on a 50mm shorter wheelbase than Crown15, just like 3IS sits on a 50mm shorter wheelbase version of the New N platform than 4GS. Yet, between the 7ES and 5LS growth spurts and the premium the Chinese market places on rear legroom, I don't think a 4IS on the shorter LC wheelbase would make sense or be particularly competitive.

And what will happen to the third Mark X? Would it be a third RWD sibling to 4IS and Crown15? Or a reworked FWD Avalon5?

But ATS and XE either already offer stretched "L' versions in China or will do so shortly. Lexus IS, on the other hand, doggedly sticks to a single shorter wheelbase.

The (TN)GA-L RWD architecture has, thus far, been released in 3 wheelbase lengths:
2870mm (113") for Lexus LC
2920mm (115") for Toyota Crown Concept / upcoming 15th-gen Crown
3125 mm (123") for 5th-gen Lexus LS

Conventional wisdom would've suggested a continuation of the Toyota Crown / Lexus GS platform relationship dating back to the original Toyota Aristo. With the GS now out of the picture, though, will the 4IS step up to the Crown platform-mate role? I certainly think so. Coincidentally (or not?), the Lexus LC sits on a 50mm shorter wheelbase than Crown15, just like 3IS sits on a 50mm shorter wheelbase version of the New N platform than 4GS. Yet, between the 7ES and 5LS growth spurts and the premium the Chinese market places on rear legroom, I don't think a 4IS on the shorter LC wheelbase would make sense or be particularly competitive.

And what will happen to the third Mark X? Would it be a third RWD sibling to 4IS and Crown15? Or a reworked FWD Avalon5?

2020 most likely.



An IS 450 makes perfect sense to me. IS 350 should NOT be the range topper anymore. Either a detuned V35A-FTS or a 3.0L Dynamic Force TTV6. ISF V8? Nah. It will be V35A-FTS or similar with added improvements.



Well, thank you. I appreciate that my man. Here is an early look at a proposal by designer C. Lee from 2016 for it, at Design Centre Atsugi in 2016. Things have wrapped up now, with major changes along the way. This was during ideation sketching.

I think:

IS 300 RWD Dynamic Force Turbo 4 Cylinder RWD
IS 300 I4 T AWD
IS 300h RWD/AWD THS
IS 350 RWD 2GR-FKS (LS 350 318hp)
IS 350 AWD
IS 450 RWD Twin-Turbo 3.0L V6
IS 450 AWD TTV6
IS F RWD High Output V35A-FTS 3.5L V6?

IC Coupe (replaces RC?)
IC Cabrio

IS SportCross in 300 and 450 grades.
Makes me sad for what could have been for the Q50. Lexus has an opportunity to poach some customers...

When it comes to engines, we have this powertrain official presentation from TMC... I doubt there will be other new engines aside from this.

I keep quoting this pic, but I think everyone needs to see it over and over again:

[​IMG]

So lets assume:

- IS450 - 3.5ltt - this is only one thats easy.
- IS300 - massaged 2.0t AR engine existing.

- IS300h or IS350h or IS450h? There is engine missing between 300h and 450h in the pic above. What is it and how does it fit? There is confirmed info that next gen Highlander will have 4cly hybrid. This cant be just standard 300h with 208-215hp - Highlander is too big for that in the USA. So it has to be some more powerful engine but it will still be 4cly. This will then likely go into IS and of course RX.

- IS350 - standard V6 for TNGA, base engine for USA.
and/or
- IS350 - new 2.5t that replaces V6 engine in other markets? 2.5t has been rumored for a while. I dont see US market preferring it over V6 though.
