The Nissan Terranaut is purely a design study, created as a research vehicle for scientists and to promote the exploratory possibilities of a four-wheel-drive vehicle. It features just three seats – one each for the “pilot, co-pilot, and lab technician” – leaving space for a laboratory in the rear of the vehicle, which includes refrigeration for a week’s worth of groceries. The Terranaut is also equipped with run-flat tires mounted on 19-inch wheels for crossing rugged terrain, and a rear bubble top that can double as an escape hatch. Don’t look for this one to hit the streets of Los Angeles and Duluth real quick.
