It looks like the next hybrid model coming to BMW dealers will be the just-introduced 5 series sedan. Photos have leaked out showing an ActiveHybrid 5 concept that is expected to debut next week in Geneva. Like the already-available ActiveHybrid 7, the 5 will likely use the mild hybrid system, but it appears that the 5 will get a more powerful motor. The 7 has a 15 kilowatt motor that doesn't allow electric-only drive. The hybrid 5 will probably have a 40 kW motor that would yield substantially better fuel efficiency in combination with an inline-six cylinder engine. The ActiveHybrid 5 should hit the streets in 2011.
