I recently got a 4th gen 2021 is350 and have been looking at mods for the car. I come to this forum a lot as there are many lexus owners with plenty of experience here. However, all of the 4th gen lexus post have been made on the 3rd gen sub because there’s no 4th gen sub. I don’t want to have to filter out previous gen posts when browsing for mods or discussions for my car lol. Maybe there’s something I’m missing and there’s a top secret 4th gen forum that I haven’t found yet. Anyways, can someone pls make a 4th gen sub?

 

There is no 4th gen. There was a thread a ways back that coined the term "3.5 gen." The current IS was a "facelift" redesign mostly skin deep, not a redesign from the ground up. There was an article today from lexus enthusiast that the next gen IS is likely to be coming in 2025 as an electric only powertrain.

 

In think this case was closed last year..

The chassis designation and powertrain are still 3rd Gen

Although there have been a few revisions since 2014, it’s mostly the same since then, with improvements made.


2021 IS revised / N-platform / original 2014

I went back and pulled out the photos released about 9 years ago now.. March 2013

Hi, congrats on your new iS!

We aren't adding a standalone 4IS subforum, here's are a couple of previous discussions on this topic with why.

I'd encourage folks to add model year to your thread title (or 3.5IS) if there is a specific question that's on an feature or part that's different in your newer model
