On the face of it that might not sound like a significantly more, but I like most people don't run the tank to empty. The comfortable reserve is about the same on tanks of various sizes, so the increase would have all gone into increased range- about 100 miles on the highway of useful increase. So yeah, if the E90 could have gone an extra 100 miles on a tank, that would have been enough. And I'm expecting the F80 will provide that extra range. Not through a larger tank, but through the claimed 25% improvement in fuel efficiency. If not, well it wouldn't be the first time I've been disappointed between initial announcements and product reality. |

I am 17.4 right now with a mix of city and highway and I just had a 320i as a loaner and it only got 23.5 avg mpg. I cannot imagine the new M4 being mid 20s with mpg in mixed driving!!

I do think that for those long road trips where you blow through a whole tank (or multiple tanks) on the freeway, the car has the potential to do much better that the E9x M3 does today. |

Having owned both N54 and N55 cars as many others here I expect similar mpg for my mixed commute at around 18 mpg. Much worse when pushing the car, likely low 10s. The E90 M3 gives me 15mpg on the commute and single digits when pushed. I don't reflect over mpg for these cars, they are more than worth it, especially the E90 M3.

Using the standard L/100km to US MPG converter: Converter
8.3l/100km is 28.34 MPG (US) 8.8l/100km is 26.73 MPG (US)

According to BMW.com, 435i gets 8.1 - 7.9l/100km (6sp/auto), which translates to 29.04 MPG (US) and 29.77 MPG (US) - COMBINED, while the Highway numbers are: 6.2 and 6.1 (37.94 / 38.56 MPG US)

That are many 2014 model year economy cars that struggle to hit 35mpg highway (Even if they have a higher EPA sticker) |

They would be impressive indeed if they were EPA numbers. But are not. The "US" listed here is a reference to EU figures being converted to US units (miles/gal vs liters/100km), not that they are in anyway endorsed by the US EPA.

If the real combined number is around 22-24, I'll very happy.

http://www.bmw.com/com/en/newvehicle...UNxlYYHhlpsOUf Btw, I think it's normal that they are close to 435i numbers. Because with so much torque, only touching the gas pedal slightly would make the car move easily. Or at the highway speeds that they test the fuel consumption (Which is like 60 mph) this car would be at 7th speed and at very low rpms, thanks to the torque. So considering this car has loads of torque at low rpms, and that it's lighter than 435i or E92 M3, I think these numbers shouldn't be surprising. Currently, I have 17.4 mpg average on my trip computer. I would expect around 23-24 MPG from the new M4.

It's getting to the point where you cannot accept the numbers on the window sticker. This is especially true if the car has auto start/stop at stop lights/drive thru or if the car has eco modes.
I do not want auto start stop in this car nor will I use an eco mode unless I'm road tripping in it and I doubt that will happen very often. Even on a road trip you might need to have some fun doing highway pulls! |
