Hello all, I'm finally posting after reading this forum for a couple of weeks. Can anyone tell me what gas mileage you're getting on your IS(250, 250AWD, 350)? I'm in the market for a car in this class, and after test driving them, it has now come down to the Audi A4 2.0T Quattro and the IS250 or 350. I still have to test drive the AWD IS250 but most dealers here in socal don't have them. I know it says it on the sticker but it's not realistic...thx

 

I have a 350 and just got up to 19.9 mpg as the avg. I would say i do about 50/50 highway / city

 

22-24mpg with mostly HWY driving (75%)

 

IS350 here. I'm getting about 18.5MPG when I'm doing 90 local and 10 freeway. Once in awhile I'll use the freeway more often and my MPG goes up to around 19.5-20ish.

 

IS250 with 750 miles im getting 26mpg with Chevron 91 octain 80% Freeway but traffic all the way, Does that count as Freeway or Street driving?

Dont get Audi This Lexus will hold value more in the long run

Goodluck

 

My IS350 is getting about 20-21 mpg with about 1,300 mi. on the odo. That's mostly city driving (including in-city freeway driving with traffic) and mostly with the ECT Power setting on. On a recent roadtrip, mostly with ECT Power off, my car was reporting a 23.9 mpg average.

Between decent gas mileage and slow depreciation, I would say the Lexus is the better long-run financial bet. But I'm very biased.

 

IS250 RWD. So far, with about 1200 miles on the odometer, I am getting an average of 26 mpg on daily driving (about 40% interstate and 60% urban/suburban roads). I usually use the ECT PWR mode, having seen little difference in gas mileage between it and the regular setting.

 

IS350. Last week, for the first time since owning the car, I spent much of the week commuting to a training center about 50 miles from home, and actually got a tad over 23 mpg for the tank. That was mostly highway, albeit with a few spots with LOTS of traffic. I wonder how well I would have done if I didn't have to pass through Rt. 18/Rt. 287 (near New Brunswick) during morning rush hour?

That's much better than I normally do. My usual commute is under 15 miles, with many short trips lunch time, evenings and weekends. With the shorter trips, I struggle to break 20 MPG.

 

I get 15-16mpg.when i drive 100% city. If i do 80% city / 20% highway i get around 17-18. I drive it like I stole it, all day everyday, anytime I jump in the car.

 

approx. 1500miles odometer
rush hour commute in CA average 22mpg at average speed of 35mph
no traffic, around 24mpg average speed of 62mph

 

1,400 miles, averaging 20mpg. That's about 50/50 mix of drving, but I do drive the car hard.

 

IS250 RWD --- about 60% city/40% hiway....getting a solid 27 mpg....
In the city, I think the key to good mileage is looking ahead and anticipating.

 

yep the moment i see a red light i just let off the gas and coast, no point in keeping on the gas, unless you want to be to the red light first for whatever reason Mom keeps on the gas even though a red light is getting close and she ends up braking at the last second Annoys the hell outta me

 

IS350 with 1600miles getting about 21mpg 50/50 city/hwy. The god awful Northern VA traffic kills my mileage.

 

IS350 with 800 miles, mostly city driving and average 21-22.
