Confirmed by a spokesman for the brand, the ever-popular supermini was previously available with two 1.5-litre four-cylinder TDCi units putting out 84bhp and 118bhp.
However, both have been taken off sale to coincide with the introduction of the Fiesta MHEV, a 48V mild-hybrid version of the 1.0-litre Ecoboost turbo petrol.
At the launch of the current, eighth-generation Fiesta in 2017, Ford predicted diesel variants would account for around 9% of the Fiesta’s UK volume. The UK spokesman confirmed that volumes are indeed “very, very low” and have been declining steadily in line with market trends.
Sales of diesel cars in general have been declining for the past half-decade across Europe, with blame laid at the door of the Volkswagen Group Dieselgate scandal and subsequent shifts in public - and government - opinions on the fuel.
From a 50% market share in 2014, the fuel made up just 18.4% of sales in September 2020 as hybrids and EVs continued to gain ground.
Manufacturers are slowly killing off diesel variants of existing models; for example, Mazda confirmed last week that its 6 saloon and estate (a company car favourite that used to have a diesel-heavy mix) will become petrol-only later this year.
