The four-speed gearbox had synchromesh on second, third and fourth speeds and retained the traditional right hand change.

The Wraith featured an independent coil sprung front suspension based on Packard 120 retaining semi elliptical leaf springs on the rear axle.

[citation needed] The hydraulic dampers at the front had their damping rate controlled by governor and so varied with the speed of the car, making it superior to its predecessor, the 25/30 H.P.

The drum brakes were assisted by a mechanical servo driven by the engine patented by Hispano-Suiza and built by Rolls-Royce under licence.

Cars based on the Wraith chassis could reach 85 mph (137 km/h); this was very dependent on the weight and style of body fitted.
