Chronology
Successor Essex V4, Essex V6

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.

Consul/Zephyr 4

The straight-4 engine started in 1951 at 1.5 L; 91.8 cu in (1,505 cc). In this form it had a bore and stroke of 79.3 mm × 76.2 mm (3.12 in × 3.00 in). With its standard compression ratio of 6.8:1 it produced an output of 47 bhp (35 kW) at 4400 rpm. It was enlarged in 1956 to 1.7 L (100 cu in) engine for the Mark II Consul by increasing both the bore and stroke to 82.5 mm × 79.5 mm (3.25 in × 3.13 in), putting the power up to 59 bhp (44 kW). This engine continued in the Mark III car, now called Zephyr.

Automobiles using the Consul engine:

Zephyr 6

The straight-6 Zephyr engine was used widely. Displacement began at 2.3 L; 137.8 cu in (2,258 cc) when it shared the same bore and stroke as the 1.5 L; 91.8 cu in (1,505 cc) 4-cylinder engine. It was produced with two standard compression ratios of 6.8:1 and 7.5:1 with outputs of 68 and 71 bhp (51 and 53 kW). It grew to 2.6 L; 155.8 cu in (2,553 cc) in the 1956 Mark II.

The Ford Pinto engine was the unofficial name for a four-cylinder internal combustion engine built by Ford Europe. In Ford sales literature, it was referred to as the EAO or OHC engine and because it was designed to the metric system, it was sometimes called the "metric engine". The internal Ford codename for the unit was the T88-series engine. European Ford service literature refers to it as the Taunus In-Line engine. In North America it was known as the Lima In-Line (LL), or simply the Lima engine due to its being manufactured at Lima Engine in Lima, Ohio.

The Ford Essex V6 engine is a 60° V6 engine built between 1966 and 1988 by the Ford Motor Company in the United Kingdom and until 2000 in South Africa although mostly in the Ford engine plant of Dagenham, Essex, which gave the engine its name. It is closely related to the Ford Essex V4 engine produced in displacements of 1.7 L and 2.0 L. Both engines share many parts since the Essex V6 was directly derived from the Essex V4; the 2.0 L Essex V4 and the 3.0 L Essex V6 in fact have exactly the same bore and stroke and share various components.

Originally, the Cologne V6 was installed in vehicles intended for Germany and Continental Europe, while the unrelated British Essex V6 was used in cars for the British market. Later, the Cologne V6 largely replaced the Essex V6 for British-market vehicles. These engines were also used in the United States, especially in compact trucks.
