During World War II, Invicta company has allowed William Watson (its designer) to continue the work on the creation of cars. So, in 1946, a new and very sophisticated car named Black Prince appeared. He was aimed to provide competition to the car of Jaguar company. However, for such small company it turned to be a pipe dream.
The moddel Black Prince had a chance to become popular and well-sold car, if the company had had the opportunity to bring the structure properly and had significantly reduced the price. The transmission of this model had proved to be very unreliable. The car received a steel frame with fully independent suspension at wishbones and longitudinal torsion bars. New Meadows engine with dual overhead camshafts and the complete supporting crankshaft had the working volume of 3 L. The Achilles heel of this vehicle was the torque converter Brockhouse that allowed to raise the ratio from 4.27 to 15.0. The first problem - the endless torment caused by a reverse gear, the closing solenoid together with bad throttle response.
For building the body of the car were invited the Charlesworth company, though after the bankruptcy the order was given to Airflow Streamlines and Jensen.
The car was equipped with P6 power unit with two overhead camshafts. It had the working volume of 2998 cubic centimetres that can provide the maximum power output of 120 horsepower and the top speed of 145 km / h. The model had only automatic transmission. Invicta Black Prince was available in two versions: 4-seater 4-door sedan and 2-door convertible.
To the problems of the car can also be ranked its big own weight (1770 kg) and a very high price (3890 pounds). However, it was planned to collect 250 cars a year. Incomplete car with the price of Rolls-Royce did not attract buyers. This interesting and noteworthy model was at low demand.
The Invicta Black Prince model with fault-prone transmission with torque converter unfortunately tried to challenge the British automotive high society.
