Originally shown at the 1953 Earls Court Motor Show, then at the 1954 show, 
the new 541 model was delivered to customers in early 1955. 
The power unit was the same Austin 3993cc six-cylinder that was being used on the 
current Interceptor model. 
A unique feature of the 541's styling was the front-hinged bonnet flap that could be 
opened or closed from a control mounted under the dash. 
Including prototypes, 173 standard 541s were built.
