Next-Generation Lexus IS Sedan to get Twin-Turbo V6 F SPORT?

Posted by Kevin on July 4th, 2018

The Australian website Driving Enthusiast is claiming the next-generation Lexus IS sedan will be available with the 3.5L twin-turbo V6 engine from the LS flagship:

The rumoured 2020 Lexus IS 400 isn’t set to be a full-cream performance model by F division, but more of a sub-performance version by its F Sport sector. It’s believed it will feature a range of performance-inspired features, such as large wheels hiding big brakes, sports suspension, and the usual F Sport treatment for the interior.

As for that engine. Lexus introduced its first turbocharged petrol engine, codenamed ‘V35A-FTS’, with the LS 500. The 3.5-litre twin-turbo unit essentially comes in to replace the naturally aspirated 3.5-litre V6.

Let’s just be upfront — this news is coming from an unsubstantiated source, there’s nothing to back up these facts. However, the V35A-FTS twin-turbo V6 makes perfect sense in the next-generation IS sedan.

That said, 416 horsepower seems excessive in the standard model, and Lexus has yet offer serious performance upgrades with their F SPORT models. If the rumor is correct and the TTV6 is not meant for the next-generation IS F, then what powers that car?

(We could stack rumors on top of each other, and suggest a detuned version of the much-hyped twin-turbo 600-horsepower V8 for the IS F. Also, the image above was a rendering of the next-gen GS F and unrelated to the IS at all.)

Well, not exactly. I just was referring to company developments, since everything else has been redesigned or killed off. The RX is 760X, but at times I question the intense similarity of the LF-1 Limitless to the RX and if upscaling the RX family to GA-L isn't a bad idea against X5 and GLE? Then NX on GA-K?

650b is the actual program code for that LF1



Actually, the IS might look more like the LS+ concept, so Triple LED implementation might not be necessity with such a design.



While RC nameplate could easily remain, instead of a new IS parallel coupe (IC?), an SC just isn't going to happen again in this market, when the LC exists.
Lastly when do you think the LCF and LSF might come out? Second gen LFA?

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?
