Mazda has a unique solution to road trips for their new MX-30, a fully electric compact SUV.
They can usually go between 25 and 35 miles on battery power, but then you have an engine to take you from coast-to-coast if need be. Several models of plug-in hybrids, or PHEVs, are available, like the Ford Escape and Hyundai Santa Fe plug-ins. They're in the sweet spot of vehicles that most people are buying anyway, compact SUVs.
Shop for a bargain at a dealership that will offer a warranty on the battery and electronic components.
