Minis will sneak beneath 100g/km of CO2 emissions when the facelifted range gets BMW’s own 1.6-litre diesel engine this autumn.
Designed to bolster BMW’s baby in the face of increasing competition fromthe Audi A1, Fiat 500 and Alfa Mito, the revised Mini focuses on improving fuel economy, reducing CO2 emissions and extending the buyer’s scope for personalisation.
The chief technical change is the switch from a PSA-sourced oil-burner to a smaller-capacity version of the engine already used in the BMW 116d.
Available in two specs — the 89bhp Mini One D and 110bhp Cooper D — it returns slightly improved economy of 72.4mpg and cuts CO2 emissions from 104g/km to 99g/km, making the car road tax-free under current VED rules.
The Cooper D has 199lb ft between 1750rpm and 2250rpm. It can reach 62mph in 9.7sec and a maximum speed of 122mph. The new diesel powerplant is also available in the Clubman and the Convertible, the first time an oil-burner has been offered in the drop-top model. Its CO2 performance is blunted slightly in both cars, though; it emits 103g/km in the Clubman and 104g/km in the Convertible.
