Prius C will be unveiled at the Tokyo Auto Show

It's hard to keep anything secret in the automotive world, and Toyota has had its fair share of leaks over the past few months. First there were leaked brochures of the Yaris-sized Prius C and most recently, the lightweight, RWD Toyota FT-86/Scion FR-S. Last month, we covered the leaked pictures/specs on the Prius C, but Toyota is just now officially confirming the arrival of the tiny hybrid.
As expected, this will be Toyota's entry-level hybrid in the U.S. market and should be priced thousands less than the standard Prius. Toyota says that the five-seat Prius C is aimed at "youthful shoppers seeking fuel efficiency, technology, and spirited driving dynamics" -- the latter characteristic has never been used to describe a vehicle wearing the Prius badge.
Toyota also claims that the Prius C will deliver over 50 mpg in the city (we're hoping that it edges closer to 60 mpg), will feature nine airbags, Bluetooth connectivity, and will be available with the Entune infotainment system.

Per the leaked specs, the 157" long Prius C will be powered by a 1.5-liter gasoline engine that generates 74hp and a single electric motor that provides 61hp.
Toyota’s Prius C will makes its first stateside appearance at the Detroit Auto Show in January.

You're not too clear on the concept of a hybrid drivetrain, are you?

Downsize the gas engine so it has lower losses, and can spend more of its time operating in its efficient zone. Use the batteries and electric motor for accelerating away from stoplights and up to highway speed.

74 hp is easily enough to maintain highway speed up any interstate grade in the country... and that's all it has to do.

That's all well and good, but the electric motor is only 61 hp.

But if both motors are working at the same time for quick acceleration as the poster above mentions, for going up to highway speeds (maintaining isn't the issue), then I could see it working fine. That's what I was wondering about this design, if it does that or not, instead of just one motor or the other when both are sub 100 hp.

Also realize I was thinking about this car when talking about the new ones being released with very low horsepower. And that car is -not- a hybrid.

A few notes:

#1. Toyota uses an oversized electric motor in thier Hybrids. I doubt that the electric motor is really capable to output more than 30 hp due to Battery limitations. I expect the combined number for the Prius C to be ~100-105. Pretty much the same ballpark as the similiarly sized Rio you mentioned. The instant torque of the electric motor should help, but 0-60 times should be in the 10s range.

#2. The Spark is an "A-segment" car. It is significantly smaller than this Prius C which is a "B-Segment" car.

#3. One way to "save" gas to prevent people from being able to "waste" it. Lower maximum HP=lower maximum gasoline consumption. Lower displacement also often means lower consumption during idle/coast... but lower displacement without turbo = low horsepower.
