Question Why has BMWNA not revised the 2013 328i MPG ratings back to 24/36?

?? Anyone have the inside scoop? It seems a little odd they haven't at least revised the highway mpg rating up an mpg or two. Did they goof it up so bad in the beginning that the EPA was totally correct in their testing?

Unfortunately, we cannot compare steady-state cruising at speed with EPA highway figures. The EPA test protocol for high includes a great amount of speed variation with the concomitant braking and accelerating. This is why everyone in every car does better on the highway than the EPA figure.

Fair point.

Loving the efficiency of the N20 tho. Hope the N55 is close.

The best I have experienced is 36 MPG @ 70 MPH for 160 miles and 34 MPG on the return trip two hours later. While not as good as the N20, it is closer than I would have predicted.

i'm averaging 17.5 on an N54 with PPK.... 80/20 city/highway. i can only hope the n20/n55 does better when i get my F30...

My N54 was a gas guzzler too. 18mpg. My n20 gets 28mpg. Hoping the N55 gets 25.

As best as I remember from the EPA video the highway cycle includes mostly steady speeds with no braking.

EDIT: just checked the testing. They do two highway tests now and combine the results somehow, but they don't specify how. They do a steady rate test with no braking and they do a congested freeway type test with four full stops.

Thats a tough one man. The N20 is an awesome motor, provides plenty of power, incredible fuel efficiency and slightly better handling due to reduced weight up front. Dont really think you can go wrong with either engines.

that's exactly my quandry. i've read that the bmw engineers and test drivers say that the N20 and n55 F30 turn in almost identical lap times on a given course-- the N55s are faster in the straights, the N20s are faster in the corners.
tbh, there is very little opportunity to go to full power on my current car in NYC--rather amusing, one of the roads i routinely drive has the lights sync'ed at 21mph. any faster and you hit reds.

I think that depends on the course, but it sounds like you would be perfectly fine with a 328i msport, in estoril blue of course

So, I'm still wondering. Did BMW retest the 328i and end up with the same results the EPA did?

Eco pro. But I use cruise control so I would get the same in comfort mode.

Absolutely. Check out the EPA highway testing speed versus time curve below. Average speed is about 48mph. But consumer Reports does accurate measurements of steaty state highway cruising (I assume at 65mph) and they list 40mpg for the 328 with the 8-speed transmission. That's the beauty of turbocharged engines: when boost is not on, you get the efficiency of a small displacement engine.

I'' take your word for this statement (though obviously things are course dependent), but I wonder whether the 335i is "under-tired" (made up word ). It weighs almost an extra 200lbs - I assume mostly at the front - yet it has the same rather skinny 225mm tires as the 328i. For comparison, the lowest trim S4 has 245s, 255s being optional.
