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

300 hp and 25 mpg?

I'll take it. You guys are getting greedy!

With the gears as long as they are, the engine appears to be strong enough for a taller 6th though.

Yeah, it's about 75% local driving. I'm in San Francisco, so a lot of my driving involves short stop-and-go trips. My '06 Civic is 100% stock, and I'm not hauling anything significant.

For those who have the 135i already, what fuel economy numbers are you actually seeing? Is the EPA on par?

If I get 20mpg I will be happy!

[BMW Dreamer]

Heck, I have been averaging 17-18mpg, 70% city, 30% highway with my 07 Civic Si. BUT the needle is usually close to 8,000 rpm's. Highway doing 80mph=29mpg.

20 average is good for a rocket.

My 07 Civic Si sedan gets 17-18 mpg mostly city. But its new and we have had alot of snow this winter. I usually warm it up for 2-3 minutes. Plus I rev the crap out of it 75% of the time. Highway doing 80mph I get 29mpg.

Mine is settling in to the 20-25 bracket quite nicely (adjusted for US gallon).

Although at first I was shocked at how quick the fuel guage would plummet towards the "fill me up!!" area I have noticed a couple of things.

1. 300+hp does not make for a economic car - live with teh power, live with the fuel economy

2. The tank is smaller (just) than the 3 series, so will appear to be more thirsty

3. The "fill me up!!" tone chime sin very early. I would say that you have as much as 1/4 tank left.

Taking that into consideration, it appears that the car is thirstier than it really is.

Ultimately, I am very happy with it. If you wanna a fuel efficent car, buy a Prius:biggrin:

I am getting about 17 in the city and 22 on highway..

135i coupe (Auto): 18/21/26
135i convert (Manual): 17/20/26
135i convert (Auto): 17/20/26

128i coupe (Manual): 18/21/28
128i coupe (Auto): 19/22/28
128i convert (Manual): 18/21/28
128i convert (Auto): 18/21/27

These are according to the new EPA test which hand out lower MPG's across the board for all vehicles. By comparison the 2008 numbers for the 335i are 17/20/26 (auto and manual).

Not on the EPA web site is the 123d, that is estimated at around 36 city, 45 hwy (give or take a few mpg). Considering these numbers, a chipped 123d with mid-6 second 0-60 times sounds better and better to me.

123d in stock form goes 0-60mph in 6.6sec. So chipped should go sub 6sec. (http://www.autozine.org/html/BMW/1er.html)

"This four-cylinder diesel engine enables the 123d Coupe to do 0-60 mph in an unbelievable 6.6 seconds"

Thanks for the new info! I've seen numbers all over the place on the 123d. Everything from 0-62 mph in 7.1 seconds, now down to a 0-60 mph in 6.6 seconds. I've also figured out that the 0-60 time includes 2 shifts for the 123d, vs only 1 shift for the 128i and 135i. So it isn't the best comparison. A better comparison would be 0-50 (all cars doing 1 shift) or 0-75 (all cars doing 2 shifts). Or in-gear 50-70 runs.

I'm now even more convinced than ever that I could get similar acceleration to a 128i with a chipped 123d, while getting nearly double the mpg. Without a sunroof, power seats, Nav, and other options weighing the car down, the idea of a sub-6 second car that gets Hybrid-like gas mileage sounds very possible!

The heck with the Prius. It can't corner, it can't accelerate, it loses power and mpg in cold weather, it doesn't have a turbo to make up for high altitude power/mpg losses. A 123d sold in the US for a price similar to the 128i would be a complete no-brainer for me if I could chip it to be a sub-6 second car. I want a high performance driver-oriented car that can still get great MPG. Not a limp-slug Prius. Is that too much to ask?

Just when I was starting to soften to the idea of settling for a 135i...

Now I'm even more fired up to get a 123d instead. How high does the price of fuel have to go before buyers DEMAND manufacturers import their high mpg models that they will only sell to the rest of the world?

I've been getting barely a hair over 18!! Oh well, it's fun at least.

[jraymond]

I'm getting 20 since I'm being a spirited break-in granny so far...I don't care what I end up getting in this. The lower the mpg the more fun you will be having.
