Default really impressed by my IS350's mpg number

i'm averaging 24mpg on a full tank of gas since i got this car couple months ago. that translates into about 330 miles on a tank before the light comes up, which is almost the same compare to the IS250 i traded it. same driving condition and i don't drive like grannies either. i'm really impressed.

Same here. Been averaging 24mpg over the life of my ownership (2+ years.) I recently did a long highway trip and averaged 30mpg for the 200 miles. Tank average after that trip was 27 mpg. For the life of me, I can't understand why anyone would buy a 250 instead of a 350?!?

Not too surprising. The automatic IS350 has the exact same city and combined mileage ratings as the IS250 manual. (The IS250 auto gets a few MPG better, but hardly night and day)

anthrax144,

Not quite sure about that. With my IS250, I can pull 650 km / 400 miles+, and for sure the IS350 would not pull that off with the routes I take. My route, work/home, and driving between Vancouver and Seattle area often. My average tank reading is around high 26 or so with 0 on the fuel remaining at that distance.

Just on the note, I tried the 350. Sure, it's amazing on it drives as I can feel the surge of the acceleration. It's definitely a nice car to have, but for want I use it for as a distance / daily driver car, the I did not need a 350.

If I were to get a leisure car in the late future, sure the 350 is something to consider.

I used to drive the 250 AWD and I sold it to my dad since I wanted a more sporty ride but I also did not want AWD (more mpg); it was harder to pull off 400s consistently. Making the switch made a difference. Before I considered the 250, I was trying to find a comparable Toyota/Lexus car which provided about 200 HP because used to drive a 99 Toyota Solara Camry XLE which was 3L V6 which was 200 HP.

I can get well north of 400 to a tank (closer to 450) if it's all highway and I run it to 0 miles left on my IS350... mostly city driving it's more in the 330-350 range.

The 250 does better, but only about 10% better on average, for a 50% hp drop.

Now, if you care not a bit about power, the 250 still gets you from A to B and offers everything else the 350 does.... but the mileage difference really is pretty small compared to the power difference.

Same here, n my MY2012 IS250. My daily commute includes highway and city and I drive all city on weekend. The avg showing is 8.5l/100km. Tank average usually start at 9.2 but end up settling at around 8.4. On a trip to Waterloo, On. I ended up getting 7.9l/100km. I fill up at 600km, and put in 48l (29 mpg) consistently.

I understand the 250 has improved gas mileage, but IMO, the trade-off is no where near worth it. If the 250 got significantly better gas mileage (2 mpg is not significant IMO) it would be a tougher decision. It would need to be more like 32mpg vs 24mpg.

A friend of mine once asked me about my gas mileage. I explained to him I got 23-24mpg but that if I babied it I could get 26-27. He's like "well that's a 10% improvement, that's pretty good!" My response - "A 10% improvement in gas mileage but a 99% decrease in fun factor." That's pretty much how I'd describe a 250 in all circumstances.

I think more about distance over the amount of refill of tanks which would show the difference show the amount you pay in your gas bill over time. It's more like 3 mpg as opposed to 2 depending on where your traveling (my route also includes uphill). Every certain amount of tanks, one would pay one extra tank to make up the same distance the 250 went.

Yes, I like the fun factor too but really didn't need it for my purposes since I use soft/baby throttling anyways. As I mentioned, I would consider the 350 in the future for leisure. I occasionally get the joke from my co-worker who owns an M3, telling me to get that F, (IS-F)!! lol, as he knows I'm fully capable of purchasing one.

On the family side if I were to get the 350, they would ask me, why do I need 300+ HP? One of them especially said, a car is mainly for point A to point B, all you need is a Corolla; this was at the time looking for a replacement for the Solara Camry which was on its last legs and was considering the 250 as a comparable car for the HP in Toyota/Lexus line when I was asking them for advise. I was like no, I'm not going back to a Corolla when my mom gave me her 95 Corolla back then before I got the Solara from my dad when he switched to Lexus.

I've averaged about 24 mpg over the past two years and 30k miles on my 350. Mixed city/highway of close to 50/50. Very happy.

250 gets around 10-15% better mileage than the 350 under a given set of driving conditions. But it is totally up to you whether that means anything, which is mostly about where your priorities lie on fuel economy vs power.

Yes there are people like me who have no interest in power. That's why I have a 250 and my lifetime average is 30 mpg, 70% hwy/30% city. And that's why hybrids are popular. It is not a financial thing at all, because these people are willing to pay more for a hybrid that gets better mileage, just like most of you people pay for performance mods to get more power. No need to argue. Just get whatever suits your needs.

Agree, it's really depends on ppl's need on choosing a 250 or 350.
In my condition, I do not need the 300+HP while I'm in traffic during rush hour, and I'm doing 70% city driving.

I hope you're kidding because not everyone need or want to pay $4-5K just for extra power.
