19 MPG is not bad. The 135i can get much worse. Like 6 mph at WOT on the Autobahns. I usually average around 22 mpg. IF you use the cruise control and do not go faster than 65 mph you can get 28 mph. I have.
You best bet (besides making sure your air filter is clean and your tire pressures are ok) is to hyper cruise. Coast as much as possible. Don't step onto teh gas pedal hard. Try to press it ever so lightly. Put the board computer into instanteous MPG and use that as a gauge as to how hard to accelerate/drive. It doesn't take that much difference is pressing the pedal down to go from low MPG to decent MPG. It is all how hard you press down on the loud pedal and how high you rev(speed, mph) that engine. |

Oh, I see now....I shouldn't use my Zune nor radio since I wont get that extra .00005 mpg that I need, because that puts soooooo much strain on the engine. And I guess drafting a semi is a good idea, you get a 1MPG increase in fuel economy. Thats cool, I guess I'll always slipstream a semi and then pay for a new windshield because I get great mileage!

I actually get better MPG with my catless downpipe and JB4 BUT that is only if you never ever punch it or anything of that sort. If you do then you get worse MPG. But if I leave it in D all day and never shift myself or gas it hard then I get better MPG.

I hate comments like this. Yes, I bought an expensive car. You know why I can buy an expensive car? Because I'm smart with my money. I save money where I can. Just because I have this car, I shouldn't care about money anymore?? It's a stupid comment. Saving money now means I can buy even more expensive things in the future.

No, it's a stupid rationalization to say you're smart with your money so you bought a 300 hp convertible. You made an emotional choice to buy a very unpractical vehicle which you are trying to make economical.

My average MPG is between 21-22. Your vert is a good deal heavier, so 21mpg ain't bad if you're hitting the loud pedal on occasion. You could increase your tire pressure by about 3psi front and rear since you do mostly highway driving. But, that will net only so much. It's not like you'll see 24-25mpg average, mixed driving, from where you are now. I've seen 25-28mpg on the computer on long, flat, and straight highway, going steady 80mph. But, play a bit with that and hit 90mph with hard accel to pass and mpg quickly drops back to 21-22mpg. Throttle input/control and wind drag/speed has the biggest effect on MPG on the highway.

I drive 50 miles per day, roughly. I get 22 mpg. I don't drive like a doofus. I punch it when I can (aka close to WOT every highway onramp and red light.. hey with the traffic around here I gotta have fun somehow), and then settle into a nice cruising speed of about 75-80 mph on the highway.
If I drove like a lot of people that I commonly see on the road, I can easily get 5 mpg less (17 mpg). If I drove like a prius driver SHOULD drive (nevermind that I see them going 80+ mph in the left lane pretty often.. definitely doing the whole hybrid thing wrong) I could probably get more along the lines of 26 mpg as Dackel mentioned. But lets say I drive those 50 miles for 5 days a week for 48 weeks a year. In reality I drive a lot more, especially on weekends. Let's say gas prices stay at around $3.50 for 93. They're more than that right now and will likely stay more than that for a while. By NOT driving like a dick and getting 17 mpg I can save close to 600 dollars a year. By driving like a saint and getting 26 mpg, I can get another 500 dollars. Conservative estimates here too. Does this make a HUGE impact in anyone's total money stockpile? Probably not. But if anyone thinks 600 free bucks for NOT driving like a dick is something to put down (not even hypermiling and everything.. just driving like I normally do), then you either have a lot of money to waste, or you're just very unconcerned with money. If Allstate offered the "not a dick driver" discount and you got 500 bucks a year discount for not driving like a dick, I reckon a lot of people would jump on the offer. Don't see this as any different. How you drive plays a pretty big role in your fuel economy, especially on this car which has the potential for both frugality and abysmal economy. Also, most people are aware of this, but some are surprisingly not. 55 is the ideal speed for fuel economy. Any higher, and the mileage drops too quickly in relation to your speed. Any lower, and yes you're getting better economy, but you're also going slower and taking more time to get to your destination, thus spending more time burning fuel. 55-60 is the sweet spot that balances speed and consumption.

After driving 10 hours yesterday to Vermont and back I ended up averaging 27.6mpg according to the computer. I had 22 average between the drive there and spirited back-road driving, then drafted a 18 wheeler most of the way home which bumped up the average a lot.
Like others said, I think changing driving habits will save the most gas and therefore money. Spending money on mods to save money on gas doesn't make sense to me. |

this is an aside, but i'd argue that most 2000+ cars are safer at 70 than most 1975 cars were at 55, so the safety concern, which is obviously the biggest counter-argument, is really nothing more than politics and perceptions. like clarkson said... speed doesn't kill; it's suddenly becoming stationary that's dangerous! so you should also speed Last edited by fourtailpipes; 10-13-2011 at 08:48 PM.. |

Can't comment on city because I can never keep myself from aggressively driving since it is just to tempting with my mods. Most likely I get worse city just because I drive more aggressively to hear my burbling on downshifts and exhaust. |

Yep, 21 mpg isn't bad...I'm still laughing at the fact someone has a Zune

A 128i convertible might have been a smarter choice if gas mileage is a concern. It is less expensive and gets better mileage. But if you want more performance it comes at the expense of gas mileage. I just traded a 500Hp, 480tq, 6.2L V8 monster for this car. I get marginally better gas mileage with the 135i. Maybe 3-4 MPG better is all.
