Toyota building new twin-turbo V6, to appear in GS, LS
The current 4th-gen Lexus GS started with the 2013 model year and went on sale back in 2012. Counting the 6-year life span for a typical Lexus model, the all-new 5th-gen GS will debut in late 2017 or early 2018 as the 2019 model. The 3.0L twin-turbo V6 will also appear on the redesigned 5th-gen Lexus LS, slated to bow to the audience early next year.
According to the Japanese auto media Mag-X and also some of our sources, the biggest news for the new GS will be its powertrain:
According to the Japanese auto media Mag-X and also some of our sources, the biggest news for the new GS will be its powertrain:
- The 2.0L turbocharged I4 (8AR-FTS) engine will get a power bump, and peak torque will be raised to around 270 lb-ft;
- A newly developed 3.0L twin-turbo engine (Toyota internal code: 943F) will join the Lexus family, with maximum output more than 400 hp, torque over 300 lb-ft (a source said the exact number is 325 lb-ft);.

i'm sure i'll get a barrage of replies detailing all the benefits of a TT V6 vs a N/A V8, but so far any TT V6 that i've encountered just doesn't sound like it belongs in a full size flagship luxury car. i have a rich indian friend who just got a quattroporte and it honestly sounds worse than my moms MDX (great sounding engine btw haha). granted the majority of owners want as little noise as possible so from a business standpoint i'm sure toyota made the right decision (as they almost always do) but the response, sound, and power delivery from a naturally aspirated engine can't be replicated. no replacement for displacement lol... i'm sure i'll be the only one disappointed though so whatever. i'm not exactly in the market for a new LS anyway.

I would take the rumored HP/TQ specs of the V6TT engine with a grain of salt as the original Japanese source (Mag-X) mentioned that this motor would be used on the next-gen GS-F which makes no sense at all.

Lexus Enthusiast also posted an article earlier this year about the same rumors of the 5th Gen GS that were derived from the Mag-X source and based on the disconnect of mentioning that this V6TT motor will be the one used for the next-gen GS-F, it made this speculation less than believable:

The rear-wheel drive front-engine TNGA platform will be adopted in the next-generation Lexus GS released in 2018. The current GS F is running a 5.0L V8 engine, but the new 2018 model will use a newly developed 3.0L V6 twin-turbo engine with a maximum output of more than 400ps/394hp.
The new engine has been given a designation of 943F, and will have a maximum torque is expected to longitudinal 45.0kgf-m (translates to 325lb/ft). This downsized engine will also be available in the next-generation LS released next year.

yes that's my point, the TT V6 is too quiet. and when i say too quiet, i mean the noise that comes from the engine itself, not the exhaust. anything can have a loud exhaust.

I wouldn't worry about noise levels- too quiet or too loud. All that can be controlled through insulation or artificial sound enhancements.
Well, I'll just say it's about time. Better late than never. I also hope to see this filter into the IS.

The use of a V6 would mean that the Supra could potentially rival Nissan’s GT-R, which swapped to a twin-turbo V6 from its tradition inline-six engine with the R35-gen model.
