Wrong again. Autocars is third rate magi that said the Prius did 21mpg.
Yes, that is what they said. The lunatic then believed them.

You can't even get that right. 23 mpg overall, including performance
testing. And that's a disgrace for such a slow car.

23mpg, when most are way into the 50s mpg. And he believes them. At 10
secs to 60 it is NOT slow. Zips along, and not CVT or gears.


So please explain to me the following taken from the FAQs on the
Toyota web site:

9. Is Prius available with a manual transmission?

No. Prius' Electronically Controlled Continuously Variable
Transmission (ECVT) comes standard and in fact, is an integral
component to the amazing performance of Hybrid Synergy Drive.® It is
so important that we often refer to it with a new name: the Power
Split Device.

Glossary

Continuously Variable Transmission (CVT)

CVT is a type of transmission with an infinite number of gear ratios
that are always changing depending upon the relative speed of the
vehicle and the engine rpm. There are several types of CVTs. Hybrid
Synergy Drive® uses an electronically controlled CVT (ECVT) which
integrates a planetary gear set into the drivetrain.

The ECVT allows the engine and motors to operate at their most
efficient points regardless of the vehicle's speed. This provides
higher fuel economy and a very smooth acceleration experience, as
there is no "shift shock" associated with conventional transmissions.
Further, the transmission requires no hydraulics or clutches (reducing
maintenance requirements), and is such a vital component to Hybrid
Synergy Drive’s amazing performance that it is often referred to by
its new name: Power Split Device.
