I don't think the 2000-4000rpm is really a rule you need to follow. The more important thing during break-in is just to try to vary the rpm's. Don't always drive at one single rpm, which means using the shifter at times could be good. Of course I also don't follow the 55mph rule because it's ridiculous to drive that slow on a freeway.

I bought an 09 Limited V6 with the navigation system option about three weeks ago. Totally loving this car.
 
As far as the break-in suggestions, that 2K to 4K rpm bit is for manual transmission cars, obviously not the automatic. Even though Hyundai doesn't specify that, it's pretty easy to figure out, as bringing the engine to 4K rpm's in the auto would mean completely flooring the throttle, and that's not good during engine break-in. I'm actually surprised how many miles Hyundai suggests for break-in. 1,200 miles is much longer than other manufactures, but I'm following it just the same.
 
And to moocow1, actually driving faster than 55 MPH on the highway with today's ~$3,70 a gallon gas prices (and rising daily) is "ridiculous." I'm absolutely amazed at being the slowest car on the freeway driving 55 MPH. People are blowing by me like I'm standing still. I guess no one has made the mental leap that the faster you drive the more gas you burn. This is especially true at anything over 55 MPH, where gas mileage plummets. People bitch and complain about high gas prices but they do absolutely nothing about changing their driving style to help mitigate the pain. They still floor-it as soon as the light turns green like they are in some kind of race, they still drive 80 MPH plus on the freeway like they're taking a pregnant wife to the hospital, and they still break at the very last instance like they're testing their breaks to make sure they work. That is ridiculous, not driving 55 MPH, not taking off very slowly from stops, and not slowing down and breaking way in advance of a stop. That is smart driving, and it seems to me there are very few smart motorists on the road these days.
 
I can't do anything about the ridiculous price of gas, but I'm sure not going to be hypocritical about it like everyone else by bitching and then not do a damn thing to change.
 
Slow down people, what is your darn rush?!

The difference in gas mileage between 55 to 70 isn't really that much for most cars with decent aerodynamics. Losing a few mpg isn't the end of the world. And the rush is that sitting there driving for an extra 20% longer on the freeway is pretty silly. The speed limit is 65, why would you go under that? And time really IS money, it's the key to investments. So you lose money by either wasting time, or wasting gas. Pick one.

In IL you would get a ticket for impeding traffic. Drive the speed limit, or get off the road.

I have to disagree with that as a general statement. My 2004 Elantra AT is quite aerodynamic for a compact car. There is a significant difference in mpg at 55 vs. 70. At 55, the engine is loafing at around 2000 RPMs, and can easily get near 40 mpg on level ground at that speed. At 70, the RPMs are around 2700 (I forget exactly how fast) and mpg drops to around 35 mpg on level ground. I have found similar behavior on every other car I've owned over 30+ years.
 
There is discussion in the press about resurrecting the 55 mph national speed limit, to save gas. Already some states are dropping their speed limits.
 
On a long trip, I can see the benefit of going 70 vs. 65. On around-town driving, I think the gas savings in slowing down far outweigh the little bit of time saved. I did a test once. I drove a route I frequently travel across town, mostly on an urban freeway but with some city streets and stoplights too, about 7 miles total. On the way to my destination, I drove the speed limit (55-65 range) on the freeway and tried to use as light a foot as possible on the gas, considering conditions. On the way home, I drove much more aggressively, went 5+ over the speed limits, didn't pay any attention to how hard I was pressing on the pedal, and sped away from stoplights. I got about 24 mpg. I also saved a whopping 1 minute on my trip.

The sonata's gearing is built for higher cruising then because 70mph = 2k rpm or so. And I've been getting 30-35 mpg on freeways so there's definitely no complaint about fuel economy so far.

Have you tested the FE at 55 and at 70 mph, on level ground? I'll bet you'll find there's a significant difference. Maybe with that 5-speed it'll run 1500 RPMs at 55.

When the 55 MPH national speed limit was forced upon us, my car at the time was a '71 Volvo 1800E, 4 speed + electronic overdrive. (4 cyl, 121 cid, 130 hp). Engine revs were the same at 71 MPH in overdrive as they were at 50 MPH in 4th gear. At 55 mph I couldn't use overdrive as the revs were too low and would foul the engine (had to keep the revs 2K when maintaining speed).
 
I think your example of an aggressive driving test is more an example of accelerating, braking, accelerating, etc, rather than driving at a relatively steady speed.
 
Back to my great old 1800E, on a highway trip of 350 miles (notwithstanding wind resistance) it just seems that 5 hours at 70 mph vs 7 hours at 50 mph would result in better mpg at the higher speed in the higher gear.

"In IL you would get a ticket for impeding traffic. Drive the speed limit, or get off the road."
 
Well I don't live in IL, I live in TX and the speed limit here is 60 mph. Driving 5 mph under that limit is hardly impeding traffic. It's called a "speed limit" for a reason, meaning it's the fastest you're legally allowed to drive. It doesn't mean you have to drive that fast. I wouldn't care if the speed limit was 65 mph, I would still drive 55 mph. As far as I'm concerned as long as I'm in the far right lane, if you don't like how fast I'm driving then go around me. I'm not going to speed up and waste my money to accommodate some impatient motorist behind me in a big rush to go nowhere.
 
Hey, if people want to go flying around at 80 mph wasting gas that's their prerogative. However for every mile per hour faster than 55 mph, fuel economy drops by about 1 percent, and the drop-off increases at a greater rate after 65 mph. So with gas prices dangerously close to $4.00 a gallon I will take every bit of gas savings I can get. And if it means driving 55 mph instead of 80 mph and taking a little longer to get to my destination, then so be it. Unless you work in a job that requires you to drive, then time does not equal money. My priority now is to save money on gas, and I will do everything I can to make that happen.

I honestly don't believe and I hope the 55 limit does not come back. Montana is a big state with lots of road between cities.
 
Pray people.....pray to the gas gods.
