I currently drive the outlander PHEV as my company car (not through choice). My previous car was the BMW 330e, so can give a good comparison between the two.
Outlander
Mileage when running without charging average about 30mpg, but expect that to drop if you try to have a little fun. It does have a small fuel tank (about £45 to fill it), last month I did 2681 miles and put in £346 worth of fuel.
The gearbox (CVT) is horrible, if you test drive one, put your foot down and listen to it rev, it's embarrassing to hear.
The multimedia interface is terrible, mine is a 65 plate so the newer versions may be better. It's menu system is very badly laid out, you have to go through a load of screen presses just to get to the phone book. When you get there, scrolling through the list can be time consuming if you have a lot of contacts.
I don't charge mine, but have used the charge button in the car (watch your MPG drop when you use this), and it gives me about 18 miles of electric. Charging this way never fully charges it though, so more miles would be available if charged at the plug.
The satnav is poor. The traffic monitoring works via radio station RDS signal, so is very limited. It usually shows you traffic jams once your in them, instead of before you arrive. The voice of the satnav must've been recorded by the most miserable woman they could find (google "The Outlander’s
satnav is evil"). The maps were out of date when I got the car, but they wanted £140 for the updates. I could buy a Tomtom with better traffic monitoring and free map updates for this.
Drop the rear seats and you get a huge boot space. I put our push bikes in there without the need to remove the front wheel for example.
On long journeys, it is very comfortable. I'm actually taking mine round Scotland in a fortnight and to be honest I think the Outlander will be good for this (except the fuel).
330e
Mileage was averaging around 46mpg, even when not charged. I did charge this car though, and was getting about 19 miles of electric. Like the Outlander, it does have a relatively small fuel tank.
The gearbox is awesome, the 8 speed ZF box is IMO as good as the DSG boxes on the VW's.
The iDrive just works and is easy to navigate. The standard satnav (I upgraded to the pronav) has very good traffic monitoring and will get you round most traffic jams.
Boot space is only reduced by 30-35mm from a standard 3 series, so no great loss, but no comparison to the Outlander obviously. However, if you want the rear seats to drop, it is an option and not standard.
Both cars are/were company cars which are great from a tax point of view. If I was buying one new, I'd go for the 330e everyday with a view to changing after three years. Wouldn't consider a used model due to the potential battery issues that may arise over time. I'm sure the repair/replacement cost would not be worth thinking about.
If your going to charge it everyday and only do short journeys, with a few long trips now and then, a PHEV will be very good. If not, you won't see the benefit of a hybrid system.
Hope this helps
