The Autobahnen are the nationally coordinated motorway system in Germany. They are officially called Bundesautobahn (pl. Bundesautobahnen), which translates as federal motorway. They are sometimes referred to as "the last refuge of the high-speed drivers" since they have no general speed limit (though about 55% of the total length is subject to local and/or conditional limits) -- the maximum recommended speed is 130 km/h = 80.8 mph.
