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.
An entry-level Mini One Convertible is joining the range for the first time, which is powered by the same 97bhp 1.6 as its hatchback sibling. In Convertible guise, the One can get from 0-62mph in 11.3secs and reach a top speed of 114mph.
The final addition to the Mini range is the Minimalism trim level. This is only available on One models and is available with the 1.6-litre engine mated to a six-speed manual with either 75bhp or 98bhp. In either guise, the Minimalism has emissions of 119g/km and fuel consumption of 46mpg.
