Grand touring comfort meets Mercedes-Benz performance in the New 2026 Airstream Interstate 24GT, a luxury Class B motorhome designed for travelers who want an upscale living experience without stepping into a larger motorized RV. Measuring 24 feet 6 inches long, the 24GT is built on the Mercedes-Benz® Sprinter 3500 Extended AWD chassis and powered by a 2.0L high-output turbo-diesel engine producing 208 horsepower and 332 lb-ft of torque, paired with a 9G-TRONIC Plus automatic transmission. With an 11,030-pound GVWR, 15,250-pound GCWR, and towing capacity up to 5,000 pounds, this touring coach combines confident road manners with serious travel capability.

Inside, the Interstate 24GT prioritizes living space with an inviting rear lounge that transforms from a comfortable daytime gathering area into a generous 70"" x 82"" sleeping space using the power rear sofa and ottomans. Premium Ultraleather® seating, power day/night shades, signature aluminum trim, two smart HDTVs, overhead storage, and a built-in workstation create an upscale environment for relaxing, working, or entertaining on the road. The spacious galley includes a 6.6 cu. ft. 12V refrigerator/freezer, 1,000-watt induction cooktop, 1.2 cu. ft. drawer microwave, solid-surface countertop, stainless-steel sink, and dedicated pantry, while the onboard wet bath provides a shower, toilet, sink, and articulated mirror.

The 2026 Airstream Interstate 24GT is equally impressive when traveling beyond traditional campground hookups. Airstream's Advanced Power System provides 10.3 kWh of heated lithium battery capacity, 400 watts of solar, and a 3,000-watt pure sine wave inverter, while the available Advanced Power Plus upgrade increases battery capacity to 17.2 kWh for extended off-grid stays. A 13,500 BTU soft-start air conditioner, diesel-fired hydronic heating and hot water, heated fresh and gray tanks, air-ride suspension, and available hydraulic leveling jacks further enhance comfort. With 23 gallons of fresh water, 24 gallons of gray water, and 11 gallons of waste capacity, the 24GT brings together luxury, advanced technology, and self-contained touring capability in one refined Class B.
