The chassis was constructed using a steel ladder frame with aluminum body panels on
early models, contributing to the car’s relatively low weight of about 2,900 pounds (1,315
kg). The suspension setup included independent front suspension with torsion bars and a
live rear axle with semi-elliptic springs, striking a balance between sporty handling and
ride comfort.
One notable aspect of the XK120’s performance was its top speed. Jaguar tested the car
