2026 Airstream Interstate 19GT with Advanced Power

The 2026 Airstream Interstate 19GT is proof that great things truly do come in compact packages. At just 19 feet long, this touring coach fits in a standard parking spot, navigates city streets with ease, and still delivers every bit of the luxury and craftsmanship Airstream is known for. Built on the Mercedes-Benz Sprinter 2500 Extended AWD chassis with a 208-horsepower turbo diesel engine producing 332 lb-ft of torque, the 19GT drives with confidence whether you are heading downtown for the weekend or exploring a remote mountain pass.

Inside, the thoughtfully designed floor plan makes the most of every inch. Belted seating for up to four passengers, a power sofa that converts into sleeping space, a fully equipped galley, a wet bath, and premium finishes throughout give you a genuine home-away-from-home experience without the bulk of a larger coach. A push-button sliding door, power seats, and advanced in-dash Mercedes-Benz technology make every entry and every mile feel refined.

The standard Advanced Power System brings 10.3 kWh of heated lithium battery capacity, a 3,000-watt pure sine inverter, an induction cooktop, and dual-input charging all working together so you can run the air conditioning, cook a full meal, keep the refrigerator cold, and power your devices without ever needing a hookup or a generator. Single-fuel diesel architecture means no propane to manage and no complexity to deal with, just clean, efficient power wherever you go. For those who want even more capability, the Advanced Power Plus upgrade bringing 17.2 kWh is available through your dealer. The 19GT is backed by a 2-year Airstream warranty and a 5-year Mercedes-Benz chassis warranty, giving you the confidence to go farther and stay longer.
