These cars are pretty similar in many ways: Scion tC: Mazda 3s hatch: The bodystyles are different, yes. I will be referring to the 3s model from here on. The Mazda, especially in hatch form should be more usable. Both have MacPhearson setup up front and double wishbones in the back. The Mazda has a 2.3 liter I4 making 160 horsepower and 150 ft-lbs of torque. The Scion has a 2.4 liter I4 making 160 horsepower and 163 ft-lbs of torque. Both have A/C, regular power stuff, and ABS standard. Both come with 17 inch wheels (standard on the tC, optional on the 3) with tires of a similar size. I'd guess they'd cost nearly the same. So which would you want at the end of the day?
