MINI has improved the engine fitted to its John Cooper Works models. Maximum power is unchanged but responsiveness is said to be better, combined with reduced fuel consumption and emissions. The new power units will be available from July.
The 1.6-litre engine uses BMW's Valvetronic system, direct petrol injection and twin-scroll turbocharging. Power is 211hp at 6,000rpm with peak torque of 260Nm produced between 1,850- and 5,600rpm. An overboost function raises maximum torque by 20Nm for short periods. For the John Cooper Works Countryman maximum power and torque are 218hp and 280Nm respectively.
Standard transmission is a six-speed manual but a six-speed automatic is now offered. The automatic comes with a Steptronic function allowing manual changes with the lever or steering wheel paddles.
Manual models come with Shift Point Display to advise on the most economical point to change gear. A stop-start system is also fitted along with Brake Energy Regeneration and electric power steering to cut fuel consumption. Economy figures depend on the model but the regular MINI JCW manages 42.8mpg on the combined cycle - giving three more miles per gallon of fuel. Clubman, Convertible and Roadster versions use slightly more petrol and the larger, all-wheel drive Countryman returns 38.2mpg.
Carbon dioxide emissions range from 155g/km for the hatchback to 184g/km for the Countryman automatic.
