Exterior
The Grenadier Fieldmaster makes an immediate impression with its bold, upright stance and classic expedition‑inspired lines. Its premium 18” alloy wheels and BFGoodrich tires add stability and presence, while the generous ground clearance gives travelers the confidence to take on winding mountain roads or unexpected weather. Wide windows create an open, panoramic feel from every seat, and the signature roof windows bring fresh air and sunlight to make scenic routes even more memorable.
Interior: Comfort That Elevates Every Drive
Inside, the Grenadier is crafted to make long drives feel effortless. Premium leather seating for five, and heated front seats welcome you with comfort in any season, while the cabin’s tall roofline and generous legroom offer a relaxed experience for every passenger. Technology is thoughtfully arranged, blending a modern touchscreen with durable physical controls and an overhead switch panel that keeps key functions within easy reach. Whether you're navigating a road trip or daily travel, the interior is designed to feel both refined and ready for anything.
Storage: Space Designed Around Real Travel
The Grenadier understands how people actually travel—with luggage, gear, and plenty of essentials. Large door pockets, a deep center console, and smart interior compartments keep everyday items organized and within reach. In the back, more than 71 cubic feet of cargo space provide room for everything from multiple suitcases to outdoor equipment, all easily accessible through split rear doors that make loading simple even in tight spaces. Built‑in tie‑downs help secure belongings, keeping trips smooth no matter the destination.
Performance: Power You Can Trust
Under the hood, the Grenadier’s 3.0L BMW straight‑six engine delivers smooth, confident power that shines on highways, hills, and everything in between. With strong torque at low revs, it handles inclines and heavier loads with ease, while its quiet, refined character makes long stretches of driving more comfortable. It’s engineered for reliability and consistency—ideal for travelers who want capability without complication.
Technology & Entertainment: Power You Can Trust
Every essential piece of driving information is displayed clearly on the central screen, which you can navigate through touch, the multifunction steering wheel, or a rotary dial. Apple CarPlay makes it easy to bring your favorite apps and navigation along, while multiple USB ports in the front and rear—and 12V outlets in both the cabin and cargo area—ensure everyone stays powered up throughout the journey. It’s technology that supports the trip without adding distraction.
