HEALDSBURG, California — When the Audi E-tron debuted in 2019, you could count its direct rivals on one hand, the Tesla Model X and Jaguar I-Pace chiefly among them. But Audi's first electric vehicle came out of the starting gate with immediate handicaps: It was slower to charge and offered just 204 miles of range vs. 325 for the Model X at the time and 234 for the I-Pace.
