A battery-electric powertrain is a good solution, but it's not the only one.
BMW is looking at multiple methods of electrification that can live alongside one another, and its latest development vehicle shows that they can all work together in harmony.
BMW on Tuesday unveiled the i Hydrogen Next fuel cell development vehicle.
Based on the current-generation X5 SUV, this vehicle previews the automaker's future efforts in hydrogen power, the next iteration of which will debut in 2022.
Eventually, BMW hopes to have fuel cell vehicles on sale by 2025, but as it notes in its press release, "the timing very much depends on market requirements and overall conditions."
BMW made a few key modifications to the X5's exterior to help it stand apart from other, more traditionally powered X5s.
