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.

If I recall correctly, LC wheelbase is almost identical to the current IS. The V8 would be theoretically heavier than an I4 or V6, but with all of the focus on rigidity and safety, it may be true that GA-L is just a fairly heavy platform... at least in the versions we've seen so far.

LC is generally around 4,300lbs I think? IS would be 2 more doors, probably less sound deadening, less premium materials, no V8. It won't surprise me to see the IS around 3,900-4k lbs.

8AR-FTS with new transmission and revisions might fit GA well... i dont think it or GR are going anywhere as base engines.

As to the weight, who knows... i doubt it will be significant loss if any.
I agree with this. Revisions might happen but overall - the 8AR and 2GR are going to stay.

I think people complaining (especially the people at ClubLexus) about the power within the 8AR Lexus IS300 don't really understand the point of the Lexus IS300.
The Lexus IS300 has always been a competitor to the Infiniti Q50 2.0T, BMW 320i, and the Audi A4 FWD Ultra. Its pretty much the "cheaper" entry-level model to their RWD luxury sedan. The Lexus IS300, within that competition, is the better car out of all of them. It doesn't need a power upgrade nor much. It just need to relatively stay in cheaper end in terms of price.
If Toyota up the power of the Lexus IS300 too much, it'll push the vehicle into 330i/Audi A4 Quattro competition, which is where the Lexus IS350 competes.
Toyota needs to keep the Lexus IS300 low on power to stay the entry-level model - especially since - within the Lexus IS line - the Lexus IS300 is their money maker for the car.

Secondly - the Lexus IS350 - competes with the 330i, Audi A4 Quattro, Infiniti Q50 Silver Sport and the C300. I do find it odd people keep comparing the Lexus IS350 to cars like the S4, 340i, Q50 Red Sport and C43 AMG. The Lexus IS350 doesn't compete there. Within the competition the Lexus IS350 competes in currently, its the second fastest car. Its still relatively a competitive engine.

This is why I think - the TTV6 will either come to the Lexus IS in two ways. Either a new Lexus "IS400" or the return of the "IS-F". Giving the fact that Toyota is a bunch of bean-counters, they'll probably produce a Lexus IS-F before a Lexus IS400. I think this because people who buy a Lexus IS tends to buy the Lexus IS300 anyways. The Lexus IS400, much like the M340i, are a niche sale. They'll probably pull more IS-F sales than IS400 sales.

4k lbs is too heavy to compete in this segment. The new 330i weights just below 3600 lbs.
A smaller platform derived from GA-L is needed.
Just because the 330i weighs below 3.6 pounds doesn't mean the Lexus IS will. Didn't Lexus spokesperson say somewhere before they are planning to stop following the Germans and doing their own thing?
4K pounds is not too heavy to compete in the segment. The Infiniti Q50 is almost 4K pounds.

4K pounds is not too heavy to compete in the segment. The Infiniti Q50 is almost 4K pounds.
The IS, even sharing LC's length and wheelbase, will be considerably lighter because a) it's narrower b) it's going to use much lighter powertrain c) there won't be as much structural strengthening in the chassis d) there won't be as much sound insulation. It doesn't make sense to use a luxury GT's weight to estimate the weight of a considerably cheaper car.

We can instead use the Crown as a reference to estimate the weight of the 4IS. The 2.0T RWD weighs around 1,700kg (3,750lbs), or 100kg heavier than the previous generation (previous gen is smaller, and doesn't have TSS). The 2.5 hybrid RWD weighs around 1,750kg (3,850lbs), and the heaviest 3.5 multistage weighs 1,870kg (4,100lbs). I expect the 4IS, if the size is similar to the Mark X, to be roughly 50kg lighter than the Crown using the same powertrian. So the IS300 RWD will be around 1,650kg which is slightly heavier than the current generation. The multistage will be the only RWD model approaching 4,000lbs. Only AWD or PHV variants will surpass 4,000.

To lose 100kg the 4IS will have to use all-aluminum construction, which is obviously something Lexus will avoid. I think 1,650kg is about the optimum weight for a mid-size sedan with a good balance of ride quality and agility.

Also, a 2.0T, whether a Dynamic Force motor or the old 8AR, is definitely here to stay. The output will very likely stay the same at 180kW/245hp, while improvements will mostly be in efficiency, NVH, and responsiveness. The IS300 as is has a lot of low hanging fruits, as the 8AR/8AT combo is not optimally tuned for performance. I'm not surprised they could get at least 0.5s 0-100 while maintaining the output; their competitors are about that much faster with similar power-to-weight ratio.

FYI, anytime cars share platforms, weight goes up and the smaller cars get hurt the most. Also the next IS will surely add more luxury and that is never light.

I don't think the Lexus owner cares one bit about weight and most cars weigh a ton now anyway. What will matter is looks, price, interior and more engine options.

The elephant in the room is the Tesla Model 3 currently selling like mad and people are so enthused about the car its crazy. Lexus needs to offer hybrids with the IS next generation and some damn good ones as well as an electric option.
