The power that now ensures a truly unique racing feel when driving with the top open is drawn from a 2.0-litre 4-cylinder engine developed on the basis of the latest engine generation with MINI TwinPower Turbo Technology, with a peak output exceeding that of the predecessor model by 15 kW/20 hp. There is also an increase in the lead over the new MINI Cooper S Convertible. The additional output of the top athlete bearing the John Cooper Works logo is now 29 kW/39 hp. The new engine also generates a maximum torque of 320 Newton metres and accelerates the MINI John Cooper Works Convertible with standard 6-speed manual transmission in 6.6 seconds from standing to 100 km/h – 0.3 seconds less than the predecessor model. In conjunction with the new generation of the optional 6-speed Steptronic sport transmission, the same sprint takes just 6.5 seconds (minus 0.6 seconds). Elasticity has also been improved by about 10 per cent. 6.1 seconds is all it takes to accelerate from 80 to 120 km/h.
