The Terreno-ion AWD sits between the flagship Strada and the compact Turismo: it is built on the non-extended Mercedes-Benz Sprinter 3500XD 170-inch high-roof diesel chassis, so it keeps a roomy, tall interior and the brand's full electrical system in a body that is shorter and easier to live with than the 24-foot extended Strada. Like the rest of the -ion line it ships with GRECH POWER MAX — a 51-volt Lithionics lithium battery delivering 16,896 watt-hours, a 3,000-watt Victron inverter, and solar — enough to run the rooftop air conditioner for roughly fourteen hours off the battery with no propane or generator, plus air suspension with auto-leveling. The interior carries hardwood cabinetry, ultraleather seating, a solid-surface counter, an induction cooktop, and a private enclosed wet bath, in Tour and Twin Bed plans sleeping two. The honest trade-offs: it is still top-of-market money, fresh-water and counter space are van-sized, and the brand is young with a thin formal review record. For buyers who want the Strada's flagship electrical system and air-ride comfort but a more manageable, non-extended footprint, the Terreno-ion is the balanced choice.
