In the context of BMW, SAV stands for Sports Activity Vehicle. It is a term used by BMW to describe their line of SUVs (Sport Utility Vehicles) or crossover vehicles. BMW SAVs typically combine the features of a traditional SUV, such as higher ground clearance and all-wheel drive, with the performance, handling, and luxury associated with BMW cars. The SAV designation is used to differentiate BMW's SUV offerings from their traditional car models.
