Michael Fisher (AKA Mr. Mobile) says the Kona Electric could make it, if there weren't so many mountains. The trip from Los Angeles to Las Vegas is a popular one and especially useful for EV range tests.
If you take the longer route past Joshua Tree National Park and through the middle of the Mojave National Preserve, you're looking at some 326 miles and well over five hours. Fisher chose the more common, shorter route, which takes you 270 miles in about four hours.
According to the EPA, the 2019 Kona Electric has an estimated range of 258 miles. So, clearly 270 miles is pushing it, especially when factoring in the hills. However, there are many other factors that impact range. Fisher says he plans to perform additional tests to get a better idea of the Kona Electric's range.
