Sure, the turbo engines may perform differently, but the E89 20i is much less powered then the 28i. That's my thinking anyway, although have to admit I haven't driven either.r

Prices range between 12K and 22K from 2012 to 2016 mileage varied from 33k to 88K.
Mmmmm... might go test drive a G29![]()
Or I might just go get another X3 :?
Im sure if you search BMW used you'd find a lot more options![]()

Theres no question the 28i holds a whefty price premium ( used) over its 2.0i sibling but its nothing more than shrewd marketing in my eyes.
I'd wager a good number of would be owners actually think they are buying a engine size between the 2.0 & 3.0 which isn't the case.
If the margin was a few hundred £ I'd understand the kudos appeal in the 28i badge but often its more like £2500 & I don't grasp that at all

Apologies if I'm wrong! :roll:
DR-Z said:Surely, apart from badging, there's some technical/mechanical difference between the 20i and the 28i? Or are you saying that BMW just change the turbo boost (i.e. map) the same engine to get more power?
If that's the case I'd absolutely agree with what you say.

So the rumor goes, nothing i have seen or read has confirmed this myth but either way they cant cope if you start pushing the car IMO and experience. They are good enough for day to day "normal" road use but start pushing it or take it any where near a track and id reckon you would need to upgrade them![]()

Agree plenty with what your saying but not every one will want to mod their car.
My choice (Nearly 4 years ago now) was either a 35i/35is or the (what i saw as) the next step down from the range topper. I had to weigh up the running costs (Use it as my daily 80 mile round trip) and fuel consumption and service cost (Plus any major costs such as turbo issues, one v two etc) and struck the happy compromise of the 28i.
Spent 6 months researching before buying, spent 6 months after looking at mods. 28i can be mapped up to 310BHP, one example: https://www.br-performance.be/en-be/chiptuning/1-cars/5-bmw/707-z4/5703-e89-2009-2019/5706-28i/?stage=4656
I do not think an 18 or 20 variant can but i stand to be corrected.
Strangely after the 6 months id spent looking at performance enhancements id decided its more than capable with the 245BHP so treat is as a touring car and I am happy to leave it alone.
After dumping the run-flats and cracked rims (afflicting the majority of the 19`s) by fitting new wheels and non run-flat tyres, apart from a sticking rear brake caliper ive had trouble free 4 years.
Paid my money took my chances and have not regretted it one bit, in the spirit of Easter id go as far as to say I have been one happy bunny with a 28i. Averages 39MPG and I don't drive like miss daisy to get it![]()

Otherwise it is my understanding too that the only differences between the 4 cylinder models are the badges and the slightly larger brakes of the 28i.

The 2.0i can easily be mapped (without issues) for around £250 to exceed the output of the 28i yet sell for approx £2500 less on like for like vehicles :?
I see little logic in holding out or seeking out a 28i then paying a premium for it over the 2.0i![]()
