Rendered: The Next-Generation Lexus IS Sedan

Posted by Kevin on October 5th, 2018

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.

GS4 has a 5cm longer wheelbase than IS3, yet is almost 20cm longer overall. It means the remaining 15cm happen at the overhangs. Overhangs are what make a car huge and difficult to drive in tight spaces, because it is harder to estimate the overhangs, that to feel the wheelbase. If the new IS gets a slightly longer wheelbase, where all to added space goes to rear seats, but overhangs remain short, it would remain a 'compact' sporty sedan, with rear seats good for long trips.
This is why the LWB 3-series gets much more rear space than SWB 5-series despite being much shorter; in fact the sub-4.8m 3-Series L has more legroom than full-size SUVs like the GLS or Range Rover. It's ridiculously space efficient.
However, for the IS a lot of wheelbase stretch will be used to allow a FMR layout (if they keep doing it for the IS). I'm expecting at most 50mm/2in longer interior cabin to make the rear usable but definitley not spacious. But usable is all they need.
To me a 4GS with 50mm shorter overhangs and front axle moving forward by 20mm is a perfect size for 4IS. The side profile of the 4GS looks very compact for its actual size. I don't think maneuvrability is a concern for sedan shoppers since they are already sacrificing maneuvrability by choosing a sedan in the first place. The only place where a 4800mm IS could have major difficulty moving is Japan, but the compact-size 3IS is a whale on Japanese roads already.

They are not going to make IS 4.8m... doesnt make much sense. They will make it similar size with larger wheelbase, like many of TNGA vehicles.

The Infiniti Q50 is in the same class as IS, it is compared to A4, C Class and 3 Series. Yet is has the same wheelbase of 2.8m and an overall length of4.81m (4cm shorter than GS4). While the Q50 has no low powered hybrid, it has a high powered hybrid version, equivalent to GS 450h, hypothetical IS 450h, that I see being replaced by the 500h used in LS and LC. New IS should have a more powerful hybrid. Just as you can choose from different power ICE, so you should be able to chose from different poyer HEV and BEV.

sure, but Lexus will not have 3 large sedans... IS needs to be small sporty sedan, or else whats the point?

Q50 is not a great vehicle, it should not be what Lexus IS targets.

Hint: 7ES is huge. It's not mid-size; it's full-size.

4800mm was the upper bound I assumed for the 4IS, of course they can build it smaller, but anything smaller than the Mark X would be a problem.

Lexus GS3 and GS4 wheelbase remained the same at 2850 mm. The IS3 wheelbase grew by 70 mm to 2800 mm from the IS2 wheelbase of 2730 mm.

Lexus IS is the smallest in this class, and as Lexus does not have any compact FWD sedan (Toyota takes care of that space), and the ES takes care of the entry (real) luxury space, the IS will likely remain in the compact sport space.

Japanese publication Mag X has a rough sketch of the 4IS:



https://www.mag-x.com/shop/products/detail.php?product_id=109

It looks as though styling will be fairly evolutionary. Also something is mentioned about an "expansion" of the IS body along with demand of GS disappearing. I can only assume this means the 4IS will get bigger, but I don't speak Japanese so cannot confirm. It matches some rumors though that the GS may disappear, and the IS may grow physically/get an expanded lineup. A new 2.4L turbo engine is also mentioned for the IS.

Maybe the IS might be the first to get the 2.4L TT in the TS050 (who knows...)
