A DUAL clutch automatic transmission is being introduced by MINI on its three and five door hatchback and convertible models.

The new seven-speed Steptronic gearbox is claimed to give faster changes enabling a sportier drive.

It replaces the six-speed automatic option on the three cars and comes with a new-look gear lever and a shift strategy that is based on navigation data to optimise efficient changes.

Other fuel efficient features included stop/start with an engine coasting function.

The Steptronic box can allow drivers to move through the gears in race track fashion by keeping the accelerator depressed while the transmission control sets the shift points precisely to ensure a continuous increase in speed.

Alternatively, it can be left in an automatic drive mode or operated manually by moving the gear lever fore or aft once the car's sports setting is engaged.

Prices for the new models are no different to the current automatics which cost from £15,910 for a three-door MINI One.
