528i MPG? (F10) or any one with a "28i" engine

[Yadizzle1]

Is there anyone on pistonheads who has an F10 528i?

I'm considering getting one for myself to replace the F10 520d that I have at the moment and was wondering what kind of MPG I can expect or hope to achieve.

That would depend on whether you are looking at a 2010/11 3 litre six cylinder 528i or the later 4 cylinder turbo 528i.

Sorry, forgot to mention. Im looking at the 4 cylinder turbo model

I have an F30 328i m sport auto. It does around 25 mpg around town or upto 38 on a long run

Driving it quickly and in sport mode it can be quite thirsty but driven carefully it can also do some impressive mpg's

It also has Eco pro mode if you are that way inclined

I know you said you're looking at the 4 cylinder, I've got the 6 cylinder version and on a steady 80mph run on cruise, it gets around 37. It has improved as the weather warms. Overall, around 30.

I would have thought the 4 cylinder would be slightly better.

Would you say that it would be worth getting the 28i engine. Fuel works out at about £20 a month extra which isn't really too bad. How do you find the car drives?

[Lozw86]

Yes I would recommend the engine. I have it in a 3 series which is slightly lighter than the 5 obviously, but it is very quick. Power delivery is strong and smooth and it'll keep up with a lot of bigger engines. It also cruises comfortably and has been completely reliable for me so far.

I prefer the 528i to the 530d, I know the 530d is quicker but the 28i feels like a proper BMW imho.

Even with a turbo 4cyl?.

I hear these new engines are good, economical, powerful etc, but I have to admit I am struggling to understand how the engine configuration can be masked...even with copious sound insulation.

The 28i engine is a bit lighter in weight than the 30d unit I believe and in the F30 3 series this offers better weight distribution. I'm not sure if this is true of the 5 series. The power outputs are not dissimilar either; 245hp vs 254hp and in the 3 series 0-60 in 5.9 vs 5.6

The 28i engine sounds a bit heartless at idle but under load and when pressing on it sounds nice enough

The 28i engine model cars are cheaper than the 30d too I think. The only thing it lacks over the 30d in my opinion is the torque.

Does it feel (power delivery) or sound at all like a 4 cylinder?. I don't think I have ever seen a -28i in the wild.

Given its a turbo, IME it doesn't feel NA of course. Its a fairly refined power delivery. BUT, you can tell its a 4 pot via the slightly thin noise and at idle it sounds like a diesel, a slightly dull tick from each injector.

Having said that, I'd have it, given I don't do the miles to warrant a diesel, the 28i engine offers performance, good for short trips, good economy, albeit not as refined as a 6 pot (though not that far off).

Can you tell the difference sat in it at idle, yes (well, if start/stop hasn't kicked in). Can you tell when overtaking or using it day to day, hardly.

Thanks for the info. I will have to keep an eye out for one and see if I can get a closer look and listen.
