BimmerFile Review: ActiveHybrid 5 Series

BMW’s ActiveHybrid 5 Series is the first two mode hybrid from the brand. Unlike the X6 and 7 Series Hybrids (one was a learning tool codeveloped with Mercedes Benz and GM , the other is barely a hybrid) the 5 Series Hybrid follows the typical formula of two drivetrains that can work together or separate using a battery pack to supplement engine drive. There are some key additions to this formula that makes this a uniquely BMW solution.
