I don’t think the Sienna has enough power, but clearly that’s not a common concern because they sell incredibly well. I wouldn’t buy one, but I wouldn’t buy one with a V6 either.

Unless someone actually likes the sound of an engine winding out, all that does, IMHO, is to add unnecessary RPM, wear, fuel-consumption, and emissions. The small turbo engine in my Encore GX, for example, has its torque peak around 1600-1700 RPM, not much above idle, so you don't have to make noise and RPM to get moving.
The down side to that, of course, is that, with the computer-fast idle set to just around that on a cold or lukewarm engine (1500-1600 RPM), it means that, unless you let it idle for about 15-20 seconds back down to a normal 900-1000 RPM or so when starting up, it means a lot of tugging at the transmission and brakes when you first shift it into gear.

No problems offering a I4, they always did. No issue with turbo, it’s the less downsizing of engine size that some members object. And I agree with that.

but it rattles. Doesn’t improve MPG and requires more maintenance. This is not progress IMO …the new I4 is progress over a I4 not a V6… not everything new is always superior. What it needs is a V6 replacement for a V6 that they sunsetted

Like it or not, engines are being downsized...nothing we can do about it.

It improves mpg by 10%. That is very significant, especially in a price-conscious family segment. We are in a world where manufacturers are switching to zero-weight oil to improve economy by ~0.2%. 10% is a massive win.

I don't have any issue with turbo 4's replacing V6's, but the 2GR was a great naturally aspirated V6 while the new turbo 4 is mediocre compared to other turbo 4's. Not as efficient, not as powerful, and much more rattly than say a BMW or VW I4. Toyota is spending a lot of money on its hybrid components to compensate for its deficiency in designing modern turbo engines.

I haven't driven any 2GR's, but I'd heard people complain that they are anemic as hell below 3,000 RPM's. I remember people complaining about it when the 3rd gen Taco came out and the 3.5 replaced the 4.0.

You have to rev the hell out of the 2GR to get power out of it; it shines best on freeway speeds. The turbo 4 would be better for cruising around town.
