The Jeep Wagoneer S Trailhawk Concept is a more rugged version of the all-electric Wagoneer S the automaker revealed in New York on Thursday. Capable of rock-crawling and deep-water fording, it’s designed to take on the same sort of challenges as gas-powered Trailhawk models do today. A production version is likely, Jeep officials said. But it’s by no means the only automaker exploring a potentially big market for off-road-ready EVs.
