Is that for the automatic? My manual isn't a big fan of anything below 50 mph, but I don't live in a fairly hilly area.

Yup, that's for auto;
Here's for manual transmission (page 492);
1st to 2nd > 17 mph (28 km/h)
2nd to 3rd > 27 mph (44 km/h)
3rd to 4th > 36 mph (58 km/h)
4th to 5th > 41 mph (66 km/h)
5th to 6th > 44 mph (71 km/h)

In a 3G, the min. was 38 mph. Just wondering if it is different in the 2012's.
Also, based on what Stew reported (70 MPH = 1800 RPM, 75 MPH 2000RPM.. 80 = 2200 ) the 6th gear really is a lot more efficient than the older 5 speed autos. Especially since the engine is larger than mine.
My 3G 3.2L with stock 17" wheels and stock tires tach'd at just about 2000 at 70 mph.
Just looked up the gear ratios for the new and the old:
old new
1st 2.7 vs 3.36
2nd 1.61 vs 2.10
3rd 1.07 vs 1.49
4th .69 vs 1.07
5th .49 vs .75
6th na vs .56
Rev 1.89 vs 2.27
final axle 4.31 vs 3.73
That explains how the 12's get such good mileage
