Combustion cars tend to be more efficient in highway driving. But with EVs, that picture can be inverted. Electric vehicles perform well in stop-and-go city driving, where they idle efficiently and replenish their batteries with regenerative braking. It’s on the highway where some (but not all) EVs struggle to hit their range numbers. For example, the Kia EV9 GT-Line AWD is rated for 270 miles but earned just 240 miles in Car and Driver 75 mph highway testing.
