Is the 3IS 250 mileage really different from a 2IS? My 2010 250 gets crazy good mileage. It's not a fast car at all, but I can sometimes get 33-35mpg on long trips, and it's extremely easy on brakes and tires due to less aggressive driving. Plenty of oomph for passing, etc... I've had fast cards and I don't miss the power. Fuel savings in real world driving is much more than advertised because of the way a 350 makes you feel like you need to drive.
Again that's a 2IS though. I know the 3IS is a little heavier but I wouldn't think it would make a huge difference in gas mileage.

Thanks for making me feel better about the decision, but sorry to hear your not that happy.
For me, when i broke it down, I figured its a small price to pay to have a car with 100 more HP and a very slight difference in gas mileage. Coming from an audi, i figured its like the difference between an a4 and an s4, however an S4 has a HUGE price premium to pay compared to the 250 vs 350. It was a hard choice to move from audi, but even though I don't have the car yet, I feel really good about going with Lexus. My a4 has not been reliable at all, constant oil issues, either engine drinking too much or oil pressure too high. And to be fair, I dont think the B8 style A4/S4s are that nice (2009 + models). #1 I see way too many on the road (a4s) and #2 unless its the S Line package, the rims they come with are hideous #3 they dont have the LFA inspired gauges which I loved during the test drive. Big step for Lexus doing this. I've read several negative reviews about Lexus' choice in the 2.5 and 3.5 L engines without turbos or supercharges, however if I told you how many times I had oil pressure problems and how much money I spent on my A4, i guarantee its directly linked to the turbo.
+1 for Reliability

I do not think I will upgrade to 3is unless they bring a new engine. it is not worthed to me

[QUOTE=corradoMR2;8141751]Congratulations. The IS will gain several new "conquest" buyers as yourself who have been loyal to the A4 or 3-series. A+ to you for putting any pride aside and making the switch to the IS. Congrats, you will have years of fun troublefree driving. ![Thumb Up](https://www.clublexus.com/forums/images/smilies/thumbsup.gif)
There was a time when I wouldn't have dreamed of buying anything but a German car. I was set on the Mercedes CLA until I went to test drive the IS 350 F Sport. Completely impressed, and the 34.2 foot turning radius sealed the deal!

+1 on getting the 350. The IS250 is frustratingly underpowered for daily driving. The IS350 is slightly overpowered for daily driving (which is what you want), although eventually you'll get used to it and it'll feel "normal" (until of course you step into a 250 or a 150 HP econobox rental and then go back to the 350).
Every time I drop off my IS250 rental and get back into my IS350, it feels like a rocket again. I'm still incredibly pleased with the 350's power 4 years into ownership.

A good friend of mine has an IS250. Her rationale is that she commutes daily in Los Angeles and is always stuck in bumper-to-bumper traffic! No opportunity to accelerate

It's not the case. I think the reason why they use turbo is to get an optimum balance between power and fuel efficiency. Most of them have better performance and get better gas mileage so I guess they like to go that route. New 335M is one full second faster than IS350 and still has better mileage.

The 350 isn't offered over here, and the 250 will not sell so much because of the fuel consumtion. The 206hp 250 uses more fuel than the 330hp Audi S4 on paper.

No the upcoming regulations for emission is forcing them to leave naturally aspirated engines. Lexus will also need to do this in time. Most likely in the mid cycle makover.

Look at the Ford Ecoboost stuff. The escape SUV for example. It's a 1.6L Turbo yet its slower and uses more fuel than the N/A 2.4L & 2.5L Honda & Toyota SUVs.
Also the Germans all use stop/start, cylinder deactivation, 8-gear ratios and lugging the engines on 8th gear doing 40kmh to obtain their paper fuel consumption.
My friend has a 328i and it uses an average of 13-14L/100km in fuel. And it's only a 2.0L 4-cyl

Here more proof..
ICCT found the worst offenders to be Germany luxury car makers. According to the study, BMW's vehicles spew about 30 percent more carbon emissions than stated by the automaker during real-world driving. Audi wasn't far behind with a 28 percent disparity, followed by Mercedes-Benz with a 26 percent difference.
On the lower end of the study, Toyota missed its stated emissions by 15 percent while PSA Peugeot Citroen's figures were about 16 percent below what drivers in the real-world would experience.
"This means that the actual fuel consumption experienced by the average driver is typically 25 percent higher than what is printed on the sales sticker," Peter Mock, managing director of ICCT Europe, told Reuters

A turbo engine is more sensitive in how you drive it. It takes a more delicate foot to keep the consumption down. And what else to expect? High power requires more fuel. However, i drove my A4 2.0Tq just a tad over stated consumption, and that engine is comparable to IS250 both in power and consumption. But the A4 is more than a second faster in 0-62mph, even though it has about 200lb more to move. It also has a lot more torque.
Still turbo is the only way to go in the future, if you don't want a hybrid. For the IS the 300h is just slightly slower in 0-62 compared to the 250, but you get almost twice the MPG.

The reason you're getting dismal mileage on the 250 is probably from gunning it too much. Do you drive it in power or normal mode most of the time?
