I vote TTV6 from Lexus. It has more torque than the rest. But in reality I wouldnt be shocked if they threw in a BMW I6 to save on R&D.

does anyone else recall that interview with a Lexus executive where he said Toyota wants to farther differentiate future Toyota & Lexus by not sharing platforms and powertrains? if true than maybe the LS' V6 TT will just be exclusive to the Lexus line up?

that would make me laugh as it would be quite hypocritical for Toyota to share their halo car with BMW but separate their own technology from their luxury lineup...not sure how that logically would make any sense for shareholders...the Lexus 2GR is now in the Highlander, Tacoma & the new Camry and I'm sure the boosted 4 cylinder will come as well..

Of course, I chose the Toyota TT V6, because I love Toyota. But, I honestly haven't the slightest clue what engine will be in this car.
All those years ago, when we initially found out about the BMW-Toyota partnership, many of us were of the understanding that Toyota wanted to co-develop a chassis, and that Toyota also needed an engine. Since then, Toyota has announced the TT V6 for the LS, and there is speculation of a TT V8 for the LCF. Both very potent engines, whose development has already been underway.
Surely, Toyota was developing this new TT V6 around the time that the BMW partnership was announced, so they knew that it would be a fairly ideal candidate for the new Supra. So, my questions are, is there something about this new V6 that Toyota doesn't want for the new Supra? Or, is the partnership with BMW solely for the chassis? Surely, Toyota could have developed this chassis on their own with the vast resources they have, especially if they already developed the motor.
These are the questions that keep me up at night.

Isn't the 'new' TTV6 just the same old 2GR but with some turbos added? I can't find much info on it.

i get the argument, but that would be a hilariously tough ask to get through the boardroom especially when they couldnt agree to do the supra project on their own..relatively speaking though the lexus powertrains have usually been a generation ahead of the toyota ones, so technically there are only a handful of examples where toyota/lexus share powertrains during the same time (usually land cruiser & toyota's other trucks/suvs). i think the NA 2GR will be going away at least on the lexus side especially now that the camry has the same v6
there ain't too much info yet, but while it shares same displacement as the 2GR, this one has completey different bore/stroke..

As HKz said, there isn't a huge amount of information on it. While it is supposed to be a similar 60-degree V6 to the 2GR, it's supposed to be 85.5x100, as opposed to 94x83, which is a relatively huge difference. A 100mm stroke is crazy long, so it's likely going to be a torque monster. Lexus stated 414hp/443lbft but doesn't specify at what RPM. In addition to that, it's a Hot-V configuration, so the exhaust ports are on the inside of the V. This usually results in great turbo response due to short runners and relative compactness, but usually involves some cooling hurdles as well. Overall, it looks like a V6 that's set up to provide torque characteristics more similar to a V8, which makes sense for the LS platform. So, while it may be loosely based on the GR engine design, it most certainly will be a unique engine in the Toyota lineup.
This doesn't mean it'll be appropriate for the Supra, however. With such a long stroke, it's most certainly not going to be revving very high, so I'm not sure if it fits in with what Toyota wants for the Supra. Granted, that can be changed, but of course, we have no clue where the engineer's heads are on that one. Like I said before, it keeps me up at night!

This one is saying something about a 400hp TT V6. The second pic with the article is low quality so the details are hard to make out.

Here is a larger version. However it just sounds like the same recycled info. A 240hp 4 cylinder, 400hp turbo V6, and something about a turbo V6 hybrid (there is a page missing). It also says they are testing at Toyota's private test track near Mount Fuji.

I have read a lot of reports that states BMW is replacing the N55 and S55 for the B58 and next gen M cars will be powered by the new S58 that will make between 450 and 460 horsepower.
