That's not true, the 2GR was a winner from the very beginning. And actually, Toyota V6 were all pretty damn good with the 3VZ-FE (not the 3VZ-E in the 4Runner, different engine) to 1MZ to 3MZ. It was just unfortunate that they let the 2GR languish for that long as it had an almost 20 year run with minimal updates.
Complain about the trombone, but the later VQs were also decent motors, same with the Honda J35/37. They all made over 300hp in later guises but at the expense of fuel economy.

Now, Ford 2.3T IMO is the best 4 cyl turbo: strong all the way from idle to redline.
330hp/385lbft from 2.3T is really close to the Acura 3.0T
466hp/554lbft from 3.5 Ecoboost now looking a little weak next to S58 ("503" hp) and Hurricane (510/510)

Ford took quite a few years to get the Ecoboost right. My honor of a world beating 4cyl goes to the VW/Audi EA888.

The ZF is a RWD tranny, Most of Mazda's lineup is still FWD, only the Miata and the CX70/80/90 (which is on the exact same platform) is RWD.
That said, from what others are saying about the tranny, Mazda has one of the better ones despite being old. There really isn't a lot of choose from on the market as the most prominent one is the Aisin 8sp, but that's a terrible product. Honda has a not very good 10 speed which they most likely won't sell to Mazda. BMW has a DCT which I don't think they'll sell to Mazda, and Mazda won't package and sell a CVT unless they have to.

they built their own to support their custom PHEV.
that said there was even a PHEV version of ZF8 they could've used.
probably a combo of packaging issue and Japanese pride.

The ZF8 PHEV isn't that efficient, ask me how I know

. Toyota's planetary gear or the standalone rear iAWD setup is significantly more efficient than the ZF8, but it seems like their iForce MAAXXXXXXXXX isn't that great on fuel either. I don't know of any other RWD setups out there, everything is FWD based.
