Particular attention has been paid to promoting superior handling stability through the structural rigidity of the bodyshell. The Lexus CT 200h's torsional stiffness has been enhanced and vibration minimised throughout by a high density of optimised weld points, comprehensive cross-bracing, extensive reinforcement to both suspension and steering assemblies, and unique lateral stabilisers to the front engine mounts.

Torsional rigidity has also been enhanced in the upper body through the use of a fully closed cross-section around the entire circumference of the back door opening, and reinforcement on the backside of the rear side member and to the rear wheel housings.
