The transmission offered for the MINI is an continuously variable transmission that also contains control. This means the driver can choose between automatic mode, which driving in city traffic and a more sporty driving with a six-gear semi-automatic

Although the continuously variable is still heavier than transmission, it is lighter than a automatic transmission.

Continuously variable transmission is different than a conventional transmission. Where conventional need a torque converter, the CVT an oil bath multi-disc coupling is electronically controlled. The transmission uses a fixed-length steel belt to connect two double belt pulleys which the drive output from the essentially offering infinitely transmission ratios.

The Powertrain Controller continuously the position of the belt pulleys and that the most suitable is provided for current driving Because the trans-mission ratio can be endlessly and infinitely, this adjustment is carried out smoothly any steps in the transmission.

The CVT gearstick has for park, reverse, neutral and mode. The letters P, R, N and D indicates settings, and an LED next to each shows where the selector is at the time.

The CVT also has a Sports driving engaged by moving the gear from position D leftwards to S. Sports mode contains a tuning of the continuously variable Within the CVT Sports mode, the can also select Steptronic for involvement in gear selection.

The automatically changes from mode to the Steptronic mode the driver changes gear by moving the gear lever or back. The shift status in transmission is also shown on an LED integrated into the speedometer. In mode, the main differences D or S mode are the fact that six transmissions are provided.

These gears are created by the that the CVT transmission is limited to six pre-determined ratios. The Steptronic offers a more agile feel, since the engine can run at up to rpm.

Failsafe protective switching errors that could the engine or transmission.

A steering with Steptronic control is as an optional extra, with the on the front and rear of the steering spokes. The switches on the front of the wheel change the gears up, and the on the rear change down.

from standstill is particularly with CVT and Steptronic, since the controlled coupling does not the full power until an speed of 2,000 rpm is reached; the power produced is restricted and evenly, resulting in rewardingly acceleration. Both operating – CVT and Steptronic – Kickdown, Fast-off and Downhill The Crawler function, familiar to of a conventional automatic transmission, is provided electronically for the CVT and Steptronic

Improved acceleration values with conventional automatic are a further advantage of CVT and Steptronic
