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.

Also, is it just me, or are these new slew of cars dropping the horsepower ridiculously low? 74 hp on the combustion engine? My little plastic Kia Rio has enough trouble accelerating to highway speeds and it's around 104 hp.

Not just you, many people can think so, but the first thing that I thought was that the Prius C is overpowered. That maybe means that the Prius C is not as well at weight optimization than the Audi A2 3l.

Max power on combustion engines is only peak power. You can't get the maximum power (except with continuously variable transmission) even on highest acceleration. Also, trying to get maximum power ruins efficiency. Electric motors have nearly maximum power at all rpms and at nearly maximum efficiency.

Power at constant speed doesn't matter because with 74hp the Prius C should go at 260km/h (162mph) (assuming same aerodinamics than audi a2 3l, a rolling resistance coefficient of 0.01 and an engine to wheel efficiency of 80%). So:

1- You don't get 104hp with your car.
2- You shouldn't want to use near peak power with your combustion engine.
3- The power on acceleration of Prius C should be about 35% higher than your car's (so 35% more acceleration with the same weight).
4- The Audi A2 3l is limited to 41bhp in ECO mode, and Prius C has 74hp+61hp.

In the end I still think the Prius C is overpowered for an eco car.
