Another Kind of CVT

Greetings:
With the Wagon Queen Family Truckster in the shop for its Million-Mile Maintenance, the Subaru dealer graciously comped me a loaner- a 2012 Outback. This is one of a growing number of cars - from Japan, mostly - equipped with a Continuously Variable Transmission.
In the Outback, punching the pedal through the floor results in a little pause, followed by a rapid rise in engine RPM to 6200, where it stays as the car gathers speed. I looked up the tranny Here. (OOoh, shiny!) It's weird not to feel/hear the engine shifting down as I accelerate, except the Honda does the same.
Instead of a Contra spring and selectable rollers, the tranny is controlled by the Engine Control Module - which puts a priority on gas mileage. 75 MPH seems to produce a steady 2050 RPM from the mild-mannered LC Boxer 4. Paddles on the steering wheel allow the selection of six "virtual" gears that in turn permit the engine to reach its 6500-RPM redline. Pretty cool, but this beast needs at least a 6. The tranny isn't particularly well-suited to pulling heavy loads, either. Lots of fail-safe devices all aimed at preventing overheating...
Shooot, maybe while I have the Outback I oughta ...
Dude! Swap in a Dio!!
