Vuosi 1936 Saurer yhtiö kehitti tämän panssaroidun ajoneuvon Itävallan armeijalle yleisnimikkeellä RR-7 tykinvetäjäksi.
Testit saatiin loppuun ja vuosi 1937 näistä traktoreista tehtiin tilaus ja ensimmäinen 12 vaunu sarja valmistui vuosi 1938, juuri ennen kuin itävalta liitettiin natsi-saksaan

The Sdkfz 254 was a fully tracked armoured scout car employed by Wehrmacht during World War II.
From 1936, the vehicle was developed under the designation RR-7 by the Saurer company as an artillery tractor for the Austrian army. Testing was completed and in 1937, an order was placed for the tractors and they were manufactured in 1938.
About 12 vehicles were made prior to Anschluss (the annexation of Austria by Nazi Germany in 1938).
Manufacture of the vehicle continued after the Anschluss. Records indicate that a total of 140 units were built with the new designation RK-7 (Räder-Kettenfahrgestell), although they were named as SdKfz 254 by the Wehrmacht. The vehicle featured a wheel-cum-track layout and a diesel motor.
The wheels were lowered when it was used on roads and retracted for tracked movement cross-country. A number saw service with the Afrika Korps, serving as artillery observation vehicles after being fitted with a radio and rail antenna.
