Thanks for the replies guys. I'm in a tough spot...I like the IS but I want the power and the 350 puts me into the range of the 3.2 Quattro A4, and 335i.

Is there a point in time which you sometimes wish you went with a 350 for a bit more power? One thing I hate is having to wind a motor out to get going. Kind of defeats the purpose of a small motor for mileage.

 

I assume that's mostly high driving right? Getting 26-29ish, I have the AWD which shouldn't have a big impact on MPG. But will never get that mpg you guys listed

Edit: 204 horse is more than you need in NY...

 

Mostly highway, yes. 160 miles round trip a day on the GSP.

 

400+ holy smokes .. i get 350miles on a good tank more or less....are they mostly freeway miles? cause i commute from san mateo to san francisco 5 x a week. whats your driving pattern? at what rpm do you shift at ? i get around 24mpg

and too the other replys of course at times i wished i opted for a 350, and of course its great to have more power, but i could use cost difference on other things. is250 is very practical for me. with gas prices over $3.50 a gallon. but otherwise the power is sufficient.

 

I do 140mi round trip, granted I have the AWD model 2IS, I still get about 30mpg. There are many threads about ppl wanting more power, but if ur commuting that much, its gonna cost u a lot in gas $$$. just IMO.

 

160 mile round trip? get a hybrid..!!!!

 

wow 400 and even 300 is crazy, i dont have the MT, but i get about 200, mayve thats cause i drive it harder or i sit in traffic.

 

omg im getting 19.4 avg mpg..... wtf... i have a 6mt and i try to keep it below 2000 rpms... yea rarely i punch it to pass traffic but not all they way....

 

I'm getting 25 mpg ...75% highway...@75 miles per hour
If driven about 5 mph above speed limit @65 mph...I can get into 27 and 28mpg range.

 

If there aren't any traffic on the freeway then you can achieve 26+ easily, I am sure there aren't much difference between MT and AWD in term of mpg. My life time mpg is about 19.6 which isn't really that bad because I do lotta local driving. I drove about 70 miles from Brooklyn (BQE to LIU exit 72) and I hit up to 35mpg on my guauge without stopping (reset trip setting when I was near BQE).

 

i also commute to and from work... (roughly 7-9 miles each trip) but im not in heavy traffic but theres times i get traffic

 

i see at least 300 on every tank. thats including some wot and high speed freeway driving, but i havent seen 350 since i broke her in.

 

My wife drives the car to work, 650km/tank doing 80km round trip on the highway even 20-30% of that trip stuck in traffic.

 

I am driving from SF to Richmond, CA everyday....about 30 miles one way
(mostely freeway)

I shift @3000-3500....

I think 204HP is good enough for a commuter car.....

Will post a pic later this week when I get the fill-up. The computer says I got 418 miles for a whole tank......

 

I get avg 380-400 mi/tank at around 26-27mpg w/ 15gal fill and I fill it up bi-weekly...my MTA bus handles the passing power
