Critchley-Norris was better known for bus chassis than for cars. They were designed by J.S. Critchley who had been with Daimler and had designed the first Crossley. Both car and bus chassis by Critchley-Norris used 40hp 4-cylinder Crossley engines, with 4-speed gearboxes and chain drive. Critchley also designed the front-drive Pullcar which was made at the same factory.
