 The original SandCat was designed around an approximate 4,000 kg gross vehicle weight (GVW) and four-man crew, although following feedback from early evaluations this was revised to around 5,000 kg and four- to five-man crew.The SandCat's then unusual and distinct trapezoidal side windows were optimised to reduce the mass of the heavy armoured glass, while maximising useful viewing angles.Now widely adopted, these were an early and distinct design feature of the SandCat, as was a feline theme in the design aesthetics.
