Welcome jazabo! We presently own a hybrid, a 2021 Highlander, and love it. As a person who studies such things in detail, the drivetrain is a marvel of engineering and simplicity. However, the future of battery technology and chemistry is a concern for a vehicle (GX) that I will consider a "keeper". Also, the hybrid system that will be incorporated into the GX will essentially be a "boost" system, and will not gain much in the realm of MPG, well, possibly 6 or so, as it will be the turbo 4-banger system as in the LC. Another consideration is the V6 can live with regular fuel per Lexus, but will the GX 4-banger hybrid? So many variables to consider!
