We don't know much about the new model, though it does look like the hatchback will carry over. That's no surprise given the Chevy Cruze, Honda Civic, Toyota Corolla, and Hyundai Elantra all offer five-door variants. You can include the hatch-only Volkswagen Golf on that list, too. The sedan is a given considering how popular the body style is in America. Expect the design to draw a lot from the Mazda Kai concept we saw last fall.
It's harder to say what Mazda might stuff under the new 3's hood. Skyactiv-X would be great, but the compression-ignition gasoline engine likely won't be ready in time for the Mazda3's debut. That's a shame, as the engine shows a lot of promise and would be a good and unique feature for Mazda. Until the EV infrastructure improves and the associated costs go down, more efficient internal-combustion engines will still have a place in the market.
