While the British car industry in the shape of BL was producing such crap as the Morris Marina, Ital, Austin Princess, the Allegro, the Maxi, the Ambassador, Morris 1100, and.........the Austin Metro, the French were producing icons such as the Citroen DS and Peugeot cars that you still see in everyday use in France, North Africa and the Middle East. The Peugeot 205 was to burst onto the scene in the early eighties. The Germans were doing ok with the Beetle the Golf was just coming into production. In the 1960s going into the '70s Ford were producing the likes of the Cortina Mk 1 enter the Lotus Cortina.......and the Escort cue the long line of successful RSs and Mexicos. The only jewel in BLs crown was the Mini but the management successfuly succeeded in destroying this icon to be resurrected later by the Germans.
The Brtish car industry was symptomatic of a very poorly managed industry producing lots of cars that people were reluctant to buy as they new they were crap. It didn't help that the workforce was much like the cars they produced. Poor designs, costly to manufacture, poor value for money, terrible performance and handling, unreliable and that frequently stopped working and would not last 5 mintues in the real world which proved to be case when the Japanese manufacturers flooded the UK market with cars offering far better value.
In 1970's Britain it was a lottery whether a British car would start in the deep mid winter and not have rusted into the ground by the Spring.
Fuel injection coupled with ECUs became widespread for car engine management systems in the mid late 1990s making cars so much more reliable and efficient. Prior to this cars were dependent on carb techology which is pretty crude in comparison.
