We just did our first road trip with the CX-90, all five of us. We did not go that far - Burlington VT area. First off, interior is really small next to our Odyssey, to the point that 2nd row passengers complained about leg room. And good thing we were travelling light, with two small carry-ons for our overnight stay.
It cruises just fine on gas, but the adaptive cruise sometimes freaked out on sudden elevation changes, or when going over a narrow highway bridge. Our avg was 8.6 l/100 km and we did not charge up at the hotel - a Level 2 EVSE was available, but that required installing an American app and linking my credit card to it - not worth the hassle, and getting some ICE exercise will do the Mazda some good.
The factory copy nav card won't take manual inputs on the go, and voice commands don't offer any US options as far as destinations go. Once in VT, I could manually enter American addresses though - weird.
Lifetime fuel economy went down from 2.3 l/100 km to 2.7 l/100 km, still pretty damn good!
Oh and on the morning of departure, a new recall notice came into the mail. A spring in the steering system may suddenly make the steering very hard to turn while at speed - fun. Have to book the procedure, a part replacement and lube.
