The stunning all-new Mazda3 sedan and hatchback made their global debut last week at the LA Auto Show and already we can't wait to get behind the wheel. However, we didn't know at the exact time launch which engines will be offered to US buyers. The only thing Mazda said was that the new 3 is compatible with a 1.5-, 2.0-, and 2.5-liter engines and a 1.8-liter diesel. Will all four of these be in the US? No. Which ones?

According to Autoblog, at launch the 2019 Mazda3 will be available with a naturally aspirated 2.5-liter four-cylinder, nearly the same unit found in the CX-5 and larger Mazda6 sedan. Power is also nearly identical, coming in at around 186 hp and 186 lb-ft of torque. Fuel economy is rated 27/36/30 mpg city/highway/combined for front-wheel-drive models, but since the new Mazda3 sports all-wheel drive, figure those figures to decrease slightly.

The second engine will be the 2.0-liter Skyactiv-X, available later next year, which is predicted to make around 188 hp and 170 lb-ft of torque. Though these power outputs are nearly identical, expect the latter to offer better fuel economy. So forget the diesel or the smaller 1.5-liter gasoline engine. Those will likely be Europe-only. However, Autoblog also learned from Mazda that, technically, it's possible to add a turbocharger to that 2.5-liter four. Will that ever be offered? The truth is that it's up to customers. Mazda emphasized that it listens to its customers, hence the reason why there's a new turbo engine or the Mazda6 and CX-5. Owners wanted more power, Mazda listened, and soon delivered. If 188 hp or so isn't good enough for new Mazda3 buyers and if they ask nicely, the automaker could offer a solution.

Meanwhile, both Mazda3 engines can be paired to either a six-speed manual or six-speed automatic. Power will be distributed to all four wheels via the automaker's improved i-Activ AWD system that works with G-Vectoring Control Plus to better control torque distribution between the front and rear wheels. We expect we'll be driving the all-new 2019 Mazda3 sometime early next year, so stay tuned for a full review.
