Ford UK's Zephyr/Consul cars used a new family of engines. The Zephyr engine included both straight-4 and straight-6 OHV engines. Production began in 1951 and lasted through to 1966, when it was replaced by Ford's Essex V4 and Essex V6 engines.
The straight-4 engine started in 1951 at 1505cc. In this form it had a bore and stroke of NaNmm. With its standard compression ratio of 6.8:1 it produced an output of 47bhp at 4400 rpm. It was enlarged in 1956 to 1.7L engine for the Mark II Consul by increasing both the bore and stroke to NaNmm, putting the power up to 59bhp. This engine continued in the Mark III car, now called Zephyr.
