www.fueleconomy.gov has 1-series MPG numbers now

[jraymond]

Sorry, BMW's engines in my humble opinion are some of the best in the world for the Buck.

I have taken a 328i on a 100 mile drive on lonesome highway, avg'd somewhere in the 80mph range and got like 29mpg.

I don't care what any #'s say, I know what I will get with a bmw engine. I also cannot get over the noise the bmw engines make, like a damn symphony to me at least.

www.fueleconomy.gov has a calculator for estimating the conversion. Here are the numbers for --> city/hwy based upon the old EPA test:

135i coupe (Manual): 17/20/25 --> 19/27
135i coupe (Auto): 18/21/26 --> 20/28
135i convert (Manual): 17/20/26 --> 19/28
135i convert (Auto): 17/20/26 --> 19/28

128i coupe (Manual): 18/21/28 --> 20/30
128i coupe (Auto): 19/22/28 --> 21/30
128i convert (Manual): 18/21/28 --> 20/30
128i convert (Auto): 18/21/27 --> 20/29

Yep, you will still get your same old MPG on your same old lonesome highway route.

The new numbers don't reflect any change in the actual cars, just a change in the test they are put through. You can expect the get the same gas mileage that you got before.

If you were able to achieve the old EPA ratings in real life driving your car, you will beat the new EPA ratings by a few MPG. If you buy a 128i coupe manual, you will probably see 20/30 mpg on your lonesome highway route.

However, most folks never achieved as good gas mileage as the old EPA ratings. These people will probably see real life numbers very close to the new EPA ratings.

Here are the '08 source numbers the EPA uses to computer the window sticker values. Includes decimal point:

There isn't a 1 series in there yet though.

I will be using mine as a company vehicle and probably putting 20-30k miles/year on it. Thank god mileage is at 48.5 cents/mile and only going up. Nate

[mjovic]

17/20/25 = Stock
15/19/22 = Stage 2
13/17/20 = Stage 2 with a LEAD FOOT!

Do what you want of course, but do realize driving a brand new vehicle that many miles/yr will have it's resale value wrecked in no time, and were talking a relatively spendy car too, not a Ford Focus.

>>135i coupe (Manual): 17/20/25 --> 19/27

That's actually slightly better than the 240hp & lighter E36 M3 got in 1999. 19/26 EPA rating for that. I used to own one and got about 28, sometimes 29 mpg on the highway if I didn't lay into the throttle.

Even with the newer EPA tests resulting in lower MPG estimates, the 128i mpg is too low to convince me to buy one. If the city mpg had been in the 20s and the hwy in the 30s the story would have been different. The 2008 128i numbers match the 2008 328i numbers exactly, so in this case, buying smaller is not saving gasoline at all.

So for now I will stick with keeping my current two car configuration - a '97 328i for fun and a Honda Civic hybrid for saving fuel. I was really hoping to be able to get back to one car.

Eventually BMW will have to make higher MPG cars because of the CAFE laws recently passed. So I will just wait until BMW decides to introduce the technology they already have to their US cars. If BMW used start/stop technology, a smaller I-6 engine on this car (w/ turbos) and put in direct cylinder fuel injection, the 128i could post some excellent MPGs without sacrificing performance. Of course by then Honda will probably have a plug in electric vehicle with limitless torque that will noiselessly skunk an any internal combustion engine...

Neil

doesn't the 128i have direct injection? i know the 135i does.

but yeah ... it's only a matter of time before bmw brings diesels to the US as well ... i bet they will start those higher up the lineup first though.

The N52 has regular PFI, not DI. All things equal DI will return better fuel economy, however being that the N54 is turbo charged and makes ~100 more horsepower, fuel economy figures look very similar. It still takes more fuel to make more HP. that will never change.

thanks for the clarification!

how is driving the civic hybrid? i would really like to hear from a typical car enthusiast. what kind of mpg do you average?

<--fellow very environmentally conscious car enthusiast. i think im going to end up with two cars before too long. hybrid for the commute/hustle/bustle, rocket for the weekends. but then i just tell myself ill take the bus to work etc and drive the fun car when need be.

[jonack]

I always thought that manual transmissions got better gas mileage????
I am disappointed in the mpg figures; was hoping for mid-twenties...

[jonack]

AND, two different salesmen from different dealerships both told me that the 135i should at least match the 24 ave mpg I presently get with the 330 xi. I thought they had some insight; I believed them. What a dope!!!

The 135i's stats on fueleconomy.gov are almost identical to those of the 330xi. AT is 18/25 for the 330xi (2006) and 18/26 for the 135i, MT is 17/26 for the 330xi and 17/25 for the 1er.

The new EPA estimates very close to real-world mileages, so I'll bet you'll be extremely close to your 24 mpg avg with he same driving habits & routes.

for last year, add the numbers and divide by 2 and you get 31 mpg, they probably finally figured that you were supposed to divide by 3 and called it the "new rating" :biggrin:

[abc]

these numbers are really lower than hoping for. any semi/quasi off the beaten path and get lost kinds of weekend "discovering america" is gonna be expensive. local driving and A/C on could be very thirsty.

[JoMo]

Doh! One of the reasons I was looking at the 128i, was that I thought it would get good gas mileage. I'm pretty disappointed. :-(

[MikeT]

These numbers are totally fine. I only get around 22 mpg with my non-hybrid '06 Civic.

[abc]

MikeT, is that mostly local driving you do for 22mpg? is your civic 100% stock, hauling alot of weight?

As for the 135i, it's pretty much as I expected. The car is extremely close to being as wide as a 335, but has a higher drag coefficient because it's more upright.

Thanks mucho for finding and posting!!

Larry you mean the honest calculations
