Going off memory I think the tachometer reads somewhere between 1500-1800rpms at those speeds with an unmoving throttle position on level road. How about yours?

Pretty sure I don't see those RPMs till I'm doing around 70-80mph when the wind resistance really starts to negatively affect acceleration and mileage. I have an FWD model though, so no idea if your AWD model has a different drivetrain or options that would cause higher RPMs like that. You're sure about that RPM at those speeds?

Great informarion on this topic here. Please read this thread:

You must realize your gas engine is NOT connected to your wheels in a hybrid.
Thus engine speed can be all over the place at any wheel speed within limits.

That's a good point worth mentioning, which is why I stated my RPMs on straight and level roads at constant MPH. OP, I've verified it a couple times since reading your thread, and I am indeed under 2k RPM between 55-65mph on straight and level roads, and at constant speed (i.e. NOT accelerating). Hope this helps, and let us know your outcome.

Mine read 2000rmp at 62mph on a straight road. There might have been a tailwind or headwind, the road may not have been perfectly level, and there may have been a drafting effect from other traffic, but 2000 would be pretty close.

Exclamation Re: rev and mph

Yours is normal.

There is no correct rpm for a given speed.

Only two rules exist:

The gas engine may never spin faster than 3,000 rpm at zero mph.
The generator will over spin and self destruct.

The gas engine may never spin SLOWER than 2,000 rpm at top speed of 104 mph. Same reason as above.

There is no neutral. The N position is just pretend. Simulated.
The gears in this car are always in mesh. There is no L gear. There is no Reverse gear either.

That thingy you put your hand on to move is basically a computer joystick.
This car is drive by wire.
