If you research other posts about the sx4 you will see the same complaints. I guess its just the nature of the beast.

As an SX4 owner, my answers to your questions would be "no" and "no."

Although I do not own a SX4 (but am looking at purchasing), calculating using top gear, final gear, and tire diameter results in 4,008 RPM 70 with the AT, and 3,290 RPM 70 with the MT.
Top Gear 1.000 AT 0.815 MT
Final Gear 4.380 AT 4.411 MT
Tire Dia 25.7"

others blog user asked me, did I use the gear "3", because the gear "3" is very close to gear "D". I told my wife mention on this. This morning she drove again on gear "D", she told me 70mph is around a bit more than 3000rpm.
let me check it again on my own the next day

I found those gear ratios at media.suzuki.com. Considering the AT gets better gas mileage than the MT, that does seem high. I double checked by using an online RPM calculator and came up with the same result. Must be an error on Suzuki's specs.

I've had an SX4 Sport AT for a few weeks now. After I saw this post, next time I was on the interstate I found that: In "D" 70mph = 2700 rpm, while in "3" 70mph = 3900 rpm. Stock tires and wheels. Hope this helps.

I think it's real close to 3400, maybe a hair above. That's with the manual transmission. I was going to suggest that you weren't running it in overdrive, but it looks like you found that out! On mine, driving 70 MPH cuts the mileage quite a bit. If my average on the readout is above 28, it will slowly drop to about 28 or below if I drive 70. If I slow down about 5 MPH, the average mileage will start to climb above 28 again.
