The rear end reminds me of the Mazda3 hatchback, but more upright. The CX-3 has a slightly higher ride height and, presumably, a bit more hatch space. Interestingly, the CX-3 is shorter from nose-to-tail than the Mazda3.
Sensors and cameras at the top of the windshield indicates that the CX-3 will be available with the automaker's i-ActiveSense safety technologies. This means lane departure alert, forward collision alert, adaptive cruise control, and active high beam headlamps.
