The bZ4X is Toyota's electric crossover at about 3 mi/kWh, often cross-shopped against efficient gas crossovers and Toyota's own hybrids. Against a 27-mpg gas crossover the per-mile fuel cost is clearly lower on home charging; against a 40-plus-mpg hybrid the gap narrows, which the calculator will show you directly.
It's one of the more affordable EVs here, which keeps the price premium — and the payback time — manageable. Home charging is where it makes the most sense; frequent public fast-charging erodes the advantage.
What to keep in mind
- Efficient crossover (~3 mi/kWh) with a lower sticker than most rivals here.
- Comparing to a hybrid? The fuel gap is smaller — check both in the calculator.
- Home charging delivers the cheapest cost per mile.
