Or so I thought until I spoke on Monday with Dr. Wolfgang Ziebart, technical design director for Jaguar Land Rover . He believes that the auto industry’s feverish race to increase the size of electric car battery packs—to thereby pump up driving range—will soon be over. More about the I-Pace “I believe that 90 to 100 kilowatt-hours is the peak,” said Dr. Ziebart, pointing to the Jaguar I-Pace and its 90-kWh battery pack, which is officially rated to go 240 miles on a single charge. “In the future, it won’t make sense to install bigger batteries.” We caught up with Dr. Ziebart last week in Redwood City, Calif., a day before the kickoff of the Jaguar Electrified Experience , a multi-city tour to introduce the I-Pace to American consumers. Dr. Ziebart is not saying that capable EVs—like the 90-kWh Jaguar I-Pace or Tesla’s 100-kWh vehicles—will have less driving range in the future. Not at all. But he believes that EV batteries can get smaller while […]
