The Bristol 411 was built from 1969 until 1976 and was the fifth Bristol model to feature a Chrysler V8 engine, however the 411 introduced a much larger 6277cc, V8. It was more powerful than the previous models and boasted a top speed of 143mph. A limited slip differential was fitted to cope with increased power. Over the seven years it was produced there were a number of changes; the Series 2 came with self-levelling suspension and the Series 3 introduced a new design for the car with the four headlamp design. A lower compression ratio was introduced too.
