JGard18, how spirited do you drive the car and how often are you in S+ mode?

Most of my daily driving is in stop and go traffic, so it's not very spirited then. When I go to hockey (once or twice per week, about 15-20 miles each way), I'll be in S+ mode, but manual shift. Certainly during those drives I'm more aggressive in how I get onto the highway and depart from stoplights.

Overall I'd say I'm not super heavy on the accelerator, though.

I'm driving from LA to Phoenix and back this week, which should be a very good optimal MPG test.

The biggest noticeable difference between IS250 & IS350 is from dig.

Once moving the difference isn't as much. But I felt that the previous gen IS350 accelerated noticeably quicker than the new IS350

What about in Sports mode? Eat's up a crap load of gas though.

I've only done a couple of hundred miles so far but, round the town in my IS300H, I'm getting an average of 35.4 miles per UK gallon. Which equates to 30MPG in US gallons..

It's also surprising that the 250/350 are often within 2-3 mpg of each other. Makes me feel okay that I ordered the big engine this time around.
Yeah, the 300h is great in lower speeds. Below 45 mph it really shines.
The down side is highway driving since the petrol engine is constantly in above 45 mph. I get about 38 mpg at 70 mph. That's more normal for a 2.5 litre, 4 cyl petrol engine.

Well, of course there comes a point where it has to be all petrol operation, but it's still a very quiet car, much more akin to my GS than to the CT200H I tried last year.
And a steady 35-38mpg , irrespective of road, is pretty good! Round town my GS used to do around 22mpg.

well, it is atkinson cycle with D4sS... it should be as efficient as possible for petrol engine.

what do you guys get at 100 mph? (l/100km?)

Shure, it's still pretty good, but i was hoping for about 42 mpg on my daily commute that consist of 6 km city driving and 90 km highway at 70 mph.

Still happy though, since the EV mode feels very luxurious. Soundless driving is the best.

I don't drive ever 100 mph since that would cost me my license. I'd imagine you'd get around 30 mpg in that speed.

So what’s the verdict here, Gentlemen? Have your mpg’s improved after ‘break-in’ (after the 1,000 mile mark)? I’ve done 700 miles and have been averaging 12 mpg’s with 50-50 city-highway driving. Dealer claims they were able to get 22 mpg’s, so I asked to go on a road test with a tech to see for myself and according to his laptop, we were getting 14 mpg’s on a short, 10-minute city drive.

Then, when waiting for my car to be washed, I saw another IS350 AWD F Sport, the owner of which said he’s done 1,700 miles and is averaging 15.6 mpg’s with 50-50 city-highway driving, who added that he’s surprised too, as his GS350 AWD gets 19 mpg’s. Also saw two IS250 AWD’s, one with 700 miles and the other with 2400 miles, which were averaging 20.5 and 20.6 mpg’s, respectively.

Insight and suggestions are welcome.

Thanks!

None of those numbers sound right to me. The worst I get is 22-23 MPG when I drive in Sport all the time. I get better than 27 MPG in Eco mode.

What accounts for the range of differences here!?

How many miles do you have, enoren?

Thanks.

After 500 miles, 24.5 mpg on normal mode driving 50/50 city and highway miles. Use to driving a hybrid and using some hypermiling techniques, but I'm really ready to just drive the car and have fun.
