The Ford Zephyr engine was a line of automotive OHV internal combustion engines that were designed for and unveiled with Ford of Britain's Zephyr/Zodiac and Consul models.

With its standard compression ratio of 6.8:1 it produces 47 bhp (35 kW) at 4400 rpm.

This engine continued in the Mark III car, which dropped the Consul name and was now called the Zephyr 4.

Displacement was 2,262 cc (138.0 cu in) in early versions that had the same bore and stroke as the 1.5-litre 4 cylinder.

The six cylinder grew to 2,553 cc (155.8 cu in) in the 1956 Mark II when its bore and stroke were increased to match the 1.7-litre inline four.
