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, to reply to this thread, if the next IS will remain RWD based, new generation GS or not, if the IS does grow in size closer, I really want it to have more rear seat space mostly. If not, the current IS 300h does not lack anything at all.

The cost of quad cams on a V4 engine kills it. Same for B4. Subaru and Porsche only do B4 for legacy reasons.
This then also applies to V6 vs I6. After BMW remaining committed to I6, Mercedes is replacing their V6 lineup by I6. JLR is also to follow suite, and so for Aston Martin (Mercedes engine). All other car makers have abandoned NA V6 for FI I4, Toyota is the only to use NA V6 (with Honda). Toyota needed BMW to put an I6 into their new Supra.

With conservative Lexus, I could see the TTV6 being the IS-F engine.
This is, precisely, what I'm expecting. It could be tuned for more power than LS 500, though, since IS would surely be lighter than LS. As I've said time and again, Lexus makes its cars as powerful as possible without incurring a U.S. EPA Gas Guzzler penalty (LFA excepted).
