The epa has a 2 mpg difference between the Sonata and the Accord, which admittedly isn't huge, but some independent tests seem to find something similar. For instance, this AutoGuide comparison had the Sonata getting 27.4 mpg while the Accord got 29.8, a difference of slightly more than 2 mpg. We actually did hit 40 once on a hwy trip with the CVT Accord, and so I think it does still have a small but significant edge of about 2 mpg over the Sonata in real world driving.
But some tests show that the Accord is beaten by about 1 mpg by the Altima and Mazda6. So those cars might set standard for mpg right now in midsize. But this AutoGuide test shows the Accord, Altima, and Mazda6 all tied at c. 29 mpg.
The 2008 Accord isn't impressive for mpg, but neither were other cars back then. It was rated 31 on the highway, and sometimes we get that at 65-70, but that's about it. That 30 number I mentioned was fully loaded with 4 people, luggage, and the AC on full blast. Back in 2008, however, most midsize cars were similar, including the previous generation Sonata. The 2008 Sonata was, in fact, rated at 30 on the highway--and so 1 mpg lower than the Accord of that year.
Here's the AutoGuide test:

Yes. With eloop the Mazda6 is hands down the winner. And even without that it seems to win some of the mpg comparison tests that I've seen.
The new skyacitiv Mazda6 seems to be the winner in some key areas, including handling, steering feel, sometimes mpg, and, although it's very subjective, maybe looks as well.
For me with a family the larger back seat and better visibility of the Accord are key features, along with the more widely available service and better navi.
But right now most comparison tests looking at most midsize cars seem to give a strong vote to the Mazda6, and I expect sales to increase at a good clip for the next several years. Mazda appears to be on a roll. They really have some engineering excellence on their side.
Having owned both Hondas and Mazdas I still prefer the Accord.

I think it is very useful to know which tire. I drove 400 miles on vacation with 4 new tires, but at 280 my TPMS flashed, and so I got off at the next exit to check it out. It was off by 3 psi, and was due to heat and the pressure variance that happens with high speed driving on hot pavement.
In other words, normal. It would have saved me an unscheduled stop if I knew which tire and how much it was off. When you have your most precious cargo in the car (my 3 kids), you can't just blow it off.
On the way back, it happened again. After slowing to 50 mph through a town for 20 miles, it shut off on it's own.
I have to give kudo's to my Turanza tires. They are fantastic in heavy rain, and I noticed a big difference in tire noise too. Very quiet, confidence inspiring tires, and very resistant to hydroplaning.

Heat would cause the pressure to go up, not down. Does your TPMS give a warning for pressure that's too high? What does it consider to be too high? You won't normally get more than a 3-4 psi difference when hot and that should already be figured into the TPMS algorithm.

Yeah backy I checked it out. Both the 2014 Sonata and the Optima are reporting horsepower reductions to 190 and 192 depending on single or dual exhaust.
Makes you wonder if our cars ever really produced 198 and 200 that I am so proud of.
After seeing many comparo's in many magazines I always noticed that our Sonoptima's were not generating performance figures commiserate with the stated horsepower and weight of the car. Seems like F/E was not the only thing being exaggerated at Hyundai-Kia.
****I got the figures directly from the official Sonata and the Optima web site. Car and Driver still report 200 and 198.

I didn't say down. I said "off". I don't remember really how much or which one. I had 3 kids screaming for food and a bathroom break. I know I evened them all out, and then on the way back TPMS flashed again, but shut off after 20 miles through town at reduced speed.
It has never come on since. I check my tires all the time.

"Heat would cause the pressure to go up, not down."
He didn't say it went down and insinuated by the term heat/speed induced that it was up. Anyway, I think most TPMS measure both ways and will give a warning whether too high or too low but that is an educated guess on my part. I would agree that 3lbs seems to be way too touchy. My Acura shows each tire pressure and when I leave the garage they are at about 30 and after a few miles on the expressway they are up to 34. I would have lights going on all the time if it measured only a 3lb variance.

So what pressure do you normally run vs. what the vehicle sticker recommends?

My tpms used to come on with my Accords, which was annoying. I replaced the regular air with nitrogen and that seemed to fix it. I'm sure you probably already know about that possible fix.

The law only requires a warning for under-inflation. I've not heard of systems warning for over-inflation. The under-inflation mandate is 25% based on the car placard recommended pressure. Since there is no mandate for overinflation it would be up to the mfr on the threshold.
