My Ride: 2007 525i Black/Black Sport, Prem, 6M, Sirius
![Default](https://5series.net/forums/images/icons/icon1.gif)
I have a US Spec 525i. Lately, with some highway and some stop and go New Jersey traffic, I've been averaging about 26-27 MPG, which I am quite happy with! I'm pretty fuel conscious (Thus my decision to purchase the 525) and light on the gas pedal.
Here is something I don't get though, the US-Spec 525i gives a 20/30 mpg rating, which seems pretty accurate in my few weeks with the car.
However, the UK-Spec 525i gives a "combined cycle" mpg of 38.2!!!! To my knowledge it is the same exact engine, and I know for sure that getting close to 40mpg out of this engine in stock form is NOT POSSIBLE! Am I missing something on the definition of "combined cycle"?
Could someone please explain this to me? It's frustrating to think that my English colleagues can be getting nearly 40 while I'm sitting at 27

My Ride: 2006 525XI, Jet black on Dakota beige. Premium and winter packages. I consider myself a purist and intend to keep my car absolutely stock and shiny.
2008 328I Convertible, Sapphire black on beige interior. Premium package, NAV, iPod adapter.
Retired: 2002 325I, Titanium silver on black leather. Premium package. Absolutely stock and proud of it.

This might be slightly OT, but I have a 523i (2.5l) and im getting 19/20mpg in the last 8weeks or so I've had it ![Frown](https://5series.net/forums/images/smilies/imported/sad.gif)
99% of my driving is Urban & I dont drive like an idiot at all.
Worth Investigating?

My 07 525xi gets 24 around town and 28 or better on the highway. Actual mileage depends if I am driving in the mountains or on the straight and flat.
