With BMW EfficientDynamic, BMW has assumed a worldwide leading role in implementing measures for reducing fuel consumption and CO2 emissions. More than one million BMW new car owners have profited from BMW EfficientDynamics since Spring 2007. Nevertheless, BMW EfficientDynamics is more than just High Precision Injection, Automatic Start/Stop function or Brake Energy Regeneration. In the long term, BMW EfficientDynamics strives towards emission-free driving with hydrogen while, in the medium term, it encompasses BMW ActiveHybrid, the drive that combines the internal combustion engine with electric motors.The first production BMW ActiveHybrid models was BMW X6 and BMW 7 Series.
The ActiveHybrid X6 is so-called full hybrid car while the ActiveHybrid 7 is a mild hybrid. Both models offer outstanding efficiency and maximum dynamics in the competitive field. High-voltage system are used in both ActiveHybrid models.
The technical design of the system ensures that the high voltages do not pose a direct risk for these persons. Such systems are referred to as intrinsically safe.
