The BMW ActiveHybrid 5 is the only model in the BMW 5 Series line-up
to be available in the exterior paint shade Bluewater metallic, and it also
stands out visually from all other 5 Series variants with door sill strips
bearing "ActiveHybrid 5" lettering, an aluminum plate on the center console with
the same ID, a custom engine cover and the visible "ActiveHybrid Power Unit"
inscription on the special casing for the high-performance battery integrated in
the luggage area.
