Why a New Crop of Electric SUV Batteries Are Coming Up Short

First it was the Jaguar I-Pace. Researchers studying electric vehicle performance at Carnegie Mellon University were surprised last fall when the sporty electric crossover received a disappointing range rating from the EPA.

That difference might not seem like much—until you’re stranded on the side of the highway. Now it’s an Audi crossover’s turn to disappoint. The company’s electric E-tron SUV, which goes on sale next month, just received its own EPA rating: 204 miles from its 95-kWh battery.
