Bundesstraße
One distinguishing characteristic between German "Bundesstraßen" and "Autobahnen" is that there usually is a general 100 km/h (62 mph) speed limit on federal highways out of built-up areas, as opposed to the merely advisory speed limit ("Richtgeschwindigkeit") of 130 km/h (83 mph) in unmarked sections of the autobahns. However, a number of "Bundesstraßen" have been extended as expressways (dual carriageways) (colloquially called "Yellow Autobahns"). Many of these have speed limits of usually 100–120 km/h, others have only an advisory speed limit like autobahns. Most sections of the federal highways are only single carriageway with one lane for each direction and no hard shoulder pull-out area.
Bobby Car
The "official" German speed record of a Bobby Cars was set on 28 April 2003 by Marco Fischer from the Bobby Car Club Coburg, who achieved a speed of 108.2 km/h. On 5 August 2018, Dirk Auer set a new record of 119 km/h at the Race at Airport event, which took place at the Bottrop-Kirchhellen airfield.
