Mini, which is debuting at this year’s Great British Fleet Event, has unveiled two new petrol-powered Cooper models to join the all-electric version of its three-door hatch.

The new petrol-powered Mini Cooper models but bear the same “minimalist design, traditional brand values and iconic go-kart handling” as the Mini Cooper Electric

Priced from £22,300, the duo aren’t built on the same platform as the electric model but bear the same “minimalist design, traditional brand values and iconic go-kart handling”.

The petrol line-up starts with the Cooper C, featuring a 156hp 1.5-litre three-cylinder engine with torque of 230Nm and capable of completing the 0-62 mph sprint in 7.7 seconds. CO2 emissions stand at 133-146g/km with fuel economy of 36.2mg-39.9mpg.

Sitting above it is the Cooper S, priced at £26,700 and equipped with a 204hp 2.0-litre four-cylinder engine that delivers WLTP emissions from 138-150g/km, economy from 35.1-38.6mpg and takes the 0-62mph sprint down to 6.6 seconds with max torque of 300Nm.

Three trims are on offer – Classic, Exclusive and Sport – with each grade offering an array of exterior and interior personalisation options. Standard equipment includes a circular OLED display and seven Mini Experience Modes.

Boot space stands at 210 litres, rising to 725 litres with the 60:40 rear seats folded.

The pair are being built at the Mini plant in Oxford, which is also being kitted out to produce the electric Mini from 2026.

Stefanie Wurst, head of Mini, said: “At Mini, ‘Power of Choice’ means that in addition to all-electric Mini models, we also offer models such as the new Mini Cooper with petrol engine. The car is ideal for all those people who want to drive a classic Mini three-door and appreciate the traditional performance and characteristic sound of a combustion engine.”

First deliveries start spring 2024.
