Mini has reworked its range to boost engine power and efficiency, while a One Convertible is also being offered for the first time.
Other additions to the range include a new Minimalism trim level, which aims to offer fuel economy and low CO2 emissions without denting on driver involvement.
The biggest engine changes can be found in the Mini Cooper S model. Power in the turbocharged 1.6-litre unit has been increased by 9bhp to 181bhp, with peak torque of 177lb ft arriving at just 1600rpm. CO2 emissions have been cut by 13g/km to 136g/km and fuel economy is up to 40.6mpg. The Cooper S can get from 0-62mph in 7.0secs and reach a top speed of 141mph.
These power and efficiency improvements have mainly been achieved by the addition of BMW’s Valvetronic system, which optimises the engine’s response within fractions of a second.
Efficiency and performance has also been improved in the Cooper model, while the Mini One’s displacement has been increased from 1.4-litres to 1.6. This results in power being increased to 97bhp, a 3bhp rise, with emissions cut to 127g/km and fuel economy improving to 43.6mpg.
