Take the uninspired underpinnings of the Toyota Yaris and mix with it an even less powerful version of the Prius hybrid powertrain and you get the Prius C. The C rides on a shorter wheelbase than the regular Prius, and the C’s combined horsepower, at 99, is less than the 134 hp of the Prius. The EPA rates the C at the same 50 mpg combined as the bigger Prius, but coaxing that level of fuel economy will drain all driving pleasure from the equation.
