Though official figures have yet to be released, the manufacturer is predicting both 120 and 143bhp variants of the revised 2.0 TDI CR engine will drop below 129g/km, including ST models, offering large savings for fleet buyers.

Cars with a Multitronic gearbox (only available on the 143bhp engine) fall from 153 to 146g/km, while the 170bhp diesel will emit 142g/km instead of 148g/km.

The new Exeo has also had a subtle but complementary facelift, introducing optional bi-xenon headlights with LED daytime running lights, plus new wheels and revised upholstery.

A sub-120g/km Ecomotive model is also planned for later in the year, with start/stop technology for the first time in the Exeo, giving a competitive rival to eco-badged offerings from the D-segment’s biggest sellers.
