If you want cheaper, you are going to take a serious hit in battery capacity. Much of the cost of a hybrid/EV is the battery, and having enough battery to give a vehicle, especially a huge, honking 4WD SUV, any sort of range or performance isn’t cheap. There is a reason most EVs and hybrids are mid-sized or smaller. To give you an idea on cost, for converting a normal car to an EV with a 60-mile range (or about as much battery as a hybrid full-size SUV would use to get 20 MPG), expect to pay $25–30k, much of that for a battery and the suspension mods required to handle the weight. I think that shows why factory-built hybrids/EVs are so pricey.
GM seems to be the only one that offers them (and not for long). If you want an EV/hybrid that is even close to the price of a gasser, you are going to have to go smaller. The Highlander hybrid starts closer to $41k, but is only a mid-sized.
There used to be a hybrid version of the Ford Escape (probably too small for your tastes) closer to $30k, but the simple fact is that those who are interested in the MPG savings of a hybrid/EV generally drive vehicles that aren’t huge. It’s inexpensive and easy to take a 2500 pound vehicle and make it go on batteries, but doing the same to a 6000 pound vehicle is more than twice as hard…. and anybody who builds one for you will charge you both for the difficulty, and for the fact that they won’t sell enough of them to make it up on volume.
