This week, Ford said its Bridgend plant in Wales has built its 20 millionth engine, 37 years after the first was made in September 1979.

A new family of technologically-advanced, fuel-efficient petrol engines has been confirmed to be built in Bridgend. With an initial investment of GBP100m, production is planned to start in late 2018.

Ford recently announced it would axe GBP81m (US$107m) from that programme's initial budget of GBP181m for engine development at the Bridgend plant but stressed this would not involve job losses.

The first engine produced in Bridgend was a CVH petrol engine for the third generation Ford Escort.
