One of the first operational armoured cars with four wheel (4x4) drive and partly enclosed rotating turret, was the Austro-Daimler Panzerwagen built by Austro-Daimler in 1904. It was armoured with 3–3.5 mm thick curved plates over the body (drive space and engine) and had a 4mm thick dome-shaped rotating turret that housed one or two machine-guns. It had a 4-cylinder 35 hp 4.4 litre engine giving it average cross country performance. Of note, both the driver and co-driver had adjustable seats enabling them to raise them to see out of the roof of the drive compartment as needed.
