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.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.
