# 2015-2018 BMW X5 xDrive40e The X5 xDrive40e was BMW's first plug-in hybrid SUV, pairing a turbocharged 2.0-liter four-cylinder with an electric motor for 308 combined horsepower. It offered approximately 14 miles of all-electric range—modest even for its era. Reviewers praised its refined driving dynamics and typical BMW luxury, but criticized the compromised cargo space (battery placement reduced trunk capacity), underwhelming electric range, and premium pricing. The system added complexity without delivering compelling efficiency for most users. It's best suited for urban drivers with short commutes and home charging who prioritize the HOV lane access and tax incentives once available. The X5 xDrive40e appeals to environmentally-conscious luxury buyers wanting BMW's badge without committing to full electrification, though purely gas or newer plug-in models often make more practical sense today.
The X5 xDrive40e combines gas and electric powertrains, requiring both conventional maintenance and battery system care. Expect premium BMW service costs, with potential high-voltage battery degradation over time. The plug-in hybrid system adds complexity and repair costs. Insurance runs higher than non-hybrid X5s due to expensive electrical components and overall luxury vehicle status.
