Bigger and better: BMW reveals all-new Mini Mini claims that the car's increased dimensions make it much more practical. As well as its increased overall size, the wheelbase is 28mm longer than the current car's, while the front seat bases are also 23mm longer for improved comfort. Boot space has increased by more than 30 per cent to 211 litres. Is the BMW Mini true to the spirit of the original Mini? The all-new interior includes the latest interpretation of Mini's familiar large central speedo and information display. There are also circular dials behind the steering wheel, while higher-spec cars gain new "controller" devices on the centre console to operate the satnav and entertainment systems. At launch three models will be available. The Cooper is powered by a new 134bhp three-cylinder, turbocharged petrol engine that replaces the current model's four-cylinder unit. The Cooper S has a turbocharged four-cylinder engine that develops 189bhp, while the Cooper D has a three-cylinder turbodiesel engine that develops 114bhp. All versions have a six-speed manual gearbox as standard; a six-speed automatic gearbox is an option for all three. Fuel economy has improved and CO2 emissions have been reduced; EU fuel economy for the Cooper rises from 52.3mpg to 62.8mpg, while CO2 emissions drop from 127g/km to 105g/km. New Mini in pictures CO2 emissions for the Cooper S have dropped from 136g/km to 133g/km, while EU Combined fuel consumption for the Cooper D has risen from 74.3mpg to 80.7mpg and CO2 emissions have dropped from 99g/km to 92g/km. Mini says the car's new suspension system is aimed at "intensifying the Mini's handling responses"; Variable Damper Control is a new option that allows the driver to choose between suspension settings biased towards either comfort or sportiness. New features available for the car include a head-up display, a Driving Assistant option that uses car-mounted cameras to control the distance to the car in front and warn of an imminent collision, a rear-view parking camera and a self-parking function. Prices start at £15,300 for the Mini Cooper, a 2.61 (£400) per cent increase over the current model. Cheaper models are expected to be introduced later in 2014. A Cooper S Works high-performance model is also likely to join the range. Mini is also expected to expand the new Mini family. Spy shots suggest that a five-door version of the hatchback is due, along with a longer estate version that will replace the Clubman.
