XM808 Twister armoured vehicle: We want one.
Between 3 and four prototypes had been built by Lockheed by 1970 including a mobility test-bed and an amphibious version. It never made it to full scale production.
This vehicle had two connected hulls with four wheels each. Each hull had its own engine and transmission. The hinged hulls could pitch and yaw independently from each other, giving the Twister a very high degree of agility and all-terrain capabilities.
It was also pretty fast on road. It was lightly armoured (6mm aluminium body) and lightly armed with a 20mm automatic canon.
