The Automatic design ensures comfortable, predictable operation in city and highway driving, with an emphasis on efficient utilization of the B47B engine's characteristics.

• Integration with vehicle electronics (engine control unit, driver assistance systems),
• Mounting geometry in the engine bay and drivetrain of the specific body style.

Such adaptation translates to stable starts, predictable downshifts, and comfortable driving under various loads. For the user, this means maintaining the typical BMW driving character, without the need for modifications to factory solutions.
