Well, I might as well jump in, too. The 4 cyl which I have in my 2006
Sonata is MORE than adequate to merge into traffic and pass on the
expressways. I confess that for 40 years I absolutely loved the 'kick in
the pants' of a 427 or 390 cubic inch engine and owned vettes, Camaro's,
Cougars, and Mustangs with those engines. Sure the 6 cyl has more 'kick'
but with all the cars on the roads today, who really and truly needs it.
Don't forget even IF the 4 turns more RPM's per mile (which hasn't been
proven), your 6 cyl will have more parts wearing out and needing
replacement...... It's an age old question with two groups agruing for
their side. No easy answer. I just got back today from a 703 mile trip
from Georgia to Pa and got 32.0 mpg up 85, 77, and 81. That's at 70 -80
mph. ) and loaded with gifts and 3 people.

Not proven? Prove it to yourself. Just look at the specification on the
web page for final gear ratios and do the math.

Which web page? I don't find this information at the Hyundai site.

Also, comparing the final drive ratio doesn't tell you anything. You
need to know the transmission ratios in high gear as well as the tire
overall diameters.

Under the specifications.

At 70 mph, my V-6 is running 2200 rpm. Yours?

I see the final drive ratio, but not the overall drive ratio or the
ratio of each transmission gear so as to calculate the overall drive
ratio. The final drive ratio is very close for the manual that I have
(3.44) vs. the automatic (3.33), however, I suspect that the overall
drive ratio is not nearly so close.

I haven't been to 70 in some time, so I'm not sure. I believe it runs
about 2200 at 55 which would be about 2800 at 70, but I'll try to
remember to check next time I'm on the highway.

I just got back from a short trip and here are the figures roughly
(within 50 RPM or so).

55 MPH = 2300
60 MPH = 2500
65 MPH = 2750
70 MPH = 2950

Basically, it is one tick on the tach for each 5 MPH increment from 55
through 70, but at 55 it is maybe a needle width above the 2250 tick
mark and at 70 it is maybe a needle width below the 3000 tick mark.
This is in 5th gear with the manual transmission and I-4 engine.

For comparison

55 = 1800
60 = 2000
65 = 2100
70 = 2200
80 = 2450
100= Did not keep a steady enough speed long enough to be accurate
