I noticed that the 2.0 turbo is now standard for all models in 2021. However, the horsepower and torque have been reduced. Does the 2021 still want premium gas? I would assume that is doesn’t to appeal to the masses and it maybe why they retuned the engine.

The '21 2.0 does not require Premium, thus partly why they have gone more broad on its use. That said, I believe it is the same XT4 2.0L Turbo engine that has had some people miffed about cylinder shutoff and a failure to shift into top gear. I have already seen a couple comments from new '21 Envision owners on that. The old 2.0, Premium gas and all, at least mated to the 9 speed pretty well.
According to the EPA: "The EPA also points out that the new Envision does not require regular premium fuel like its predecessor. So basically, less and cheaper gas at the expense of 19 horsepower." They did this to improve the fuel economy substantially over the previous year which had the same powertrain. The 2021 Envision AWD will return 22/29/25 mpg city/highway/combined. This is two better in the city, four better on the highway, and three better overall. You do lose about 1 second in 0-60 mph acceleration - going up from 7.1 to 7.6 seconds but that is fast enough to merge onto any highway anywhere.

The engines are alot different.
This is the new LSY Engine.
A successor to the LTG debuted in the 2019 XT4 and the 2019 CT6 The LSY adds active fuel management and a start stop system putting more priority to fuel economy than performance. Peak output is lower than the LTG, but is achieved at lower rpm for both power and torque. Bore is 83.0 mm (3.27 in), and stroke is 92.3 mm (3.63 in).
