Hi guys, I own a F30 ActiveHybrid 3 at the moment, great car, awesome power, very quick off the line and sounds great as well. Car is a bit of a "Sleeper" until you floor it. Hybrid power is very noticeable on acceleration. In traffic batteries will drive car for about 20 mins, and on the open road the car will coast on batteries up to about 130kms/h. Don't think this car was meant to be a Hybrid but more designed to be a performance car with additional electric power.
Cheers for now.
