I've gone through most of the reviews and articles about the new Supra and am very excited to hear that practically all reviews are coming back positives with some negative feedback on some things such as light steering/lack of better steering feel or interior feeling small and cramped and being a little difficult to see out of. I guess it could have been worse. I also recall though that someone from Toyota mentioned that they want to also adopt the strategy of something similar to Porsche and BMW as well where they release incremental updates through the model years to keep interest going and sales going. It seems that if they follow the Porsche model, which has a base model, the S model, the Touring model, and the GTS model, it seems that we're in for a treat with the Supra. I guess the 4 banger is the base model even though the US isn't confirmed to be getting it so far as I've read. If the current configuration of the Supra is the S model, it seems that we may be getting an available tune for the Supra to bump power up and I thought that I read somewhere that could be a possibility. It seems that we don't have to look to far for these answers as I'm guessing they're just going to follow what BMW has done in the past. As BMW has done in the past with their 3.0 litter in-line 6, they usually release a tune to bump the hp up a bit but still not close enough to the M version. I'd guess they're going to do the same with the Supra and then the GRMN version will use a detuned version of the next gen m3/m4 engine. It's also possible that when this does happen, we'll see the manual and dual-clutch in the car with the m engine int he GRMN version.
