The most powerful versions in the Mini range have been equipped with new exhaust filtration technology to conform to Euro 6d-TEMP requirements and get through WLTP emissions regulations.
The alterations to the 2.0-litre, twin-turbocharged four-cylinder engine haven’t affected the car’s performance.The JCW produces 231bhp and is capable of 0-62mph in 6.3sec in hatchback guise, 0.3sec quicker than the convertible.
Fitted with the standard six-speed manual gearbox, the hatchback produces 158-157g/km of CO2, while the convertible is rated at 162-161g/km, depending on spec. The optional eight-speed automatic gearbox brings emission levels down to 142-140g/km and 148-145g/km respectively.
Mini claims the new particulate filter has been integrated into the exhaust system in such a way that allows for “a characteristic sound inside and outside the vehicle.”
