A
dune buggy is a recreational
motor vehicle with large
wheels, and wide
tires, designed for use on sand
dunes,
beaches, or desert recreation. It is called a "Beach Buggy" in the
United Kingdom,
Ireland and many other English speaking countries. The design is usually a modified vehicle and engine mounted on an open
chassis. The modifications usually attempt to increase the power-to-weight ratio by either lightening the vehicle or increasing engine power or both. Dune buggies designed specifically for operation on open sand are called
sandrails.
