The revving is the specific thing newbies don't like about an eCVT. They find it disturbing because the sound of the engine isn't increasing with the speed of the car but just stays high. The engine runs at the best speed to generate the output it needs to move the car and actually provides better accelleration because all the power of the drivetrain is available at any speed.
The engine revving does not increase speed because it is part of warming the CAT for emissions. I've said many times now that Ford's patented warm-up strategy retards the timing and uses the traction motor and the battery during this mode to propel the vehicle.
Don the engineer thinks a pressure pump is needed to pressurize the gas tank when pressure is created when liquid gasoline becomes a vapor.
