Ever since Mazda made any mention of their SkyActiv-X engine, the Japanese automaker has been claiming that it will be a revolution. It's been almost two years since Mazda showed us how it works, but they haven't mentioned anything that's probably been on everyone's heads: what are the specs?

We were expecting to see some figures when the all-new Mazda 3 made its world debut, but none surfaced. There were also no specs shown during its ASEAN premiere at the Singapore Motor Show, and still, nothing was revealed in its local preview. After a long wait, we finally know how much power this "revolutionary" engine makes.

Here are the full specs of Mazda

The SkyActiv-X has a displacement of 2.0-liters, which sounds pretty normal these days. The horsepower figure is then rated at 180 PS, along with a torque figure of 224 Nm. Those are impressive, if not outstanding outputs. But what makes the specs impressive is the fact that it was able to get those numbers without the use of a turbo. Yes, the SkyActiv-X engine is all motor, and it doesn't even use spark plugs. Before you ask, the SkyActiv-X is a gas-fed engine.

With specs like that, it soundly trumps other naturally-aspirated 2.0-liter engines in its class. For example, the two-liter Corolla Altis has 145 PS and 187 Nm of torque, while the Hyundai Elantra makes 152 PS and 192 Nm of torque. This engine is also quite the leap from Mazda's own 2.0-liter SkyActiv-G, which made 155 PS and 200 Nm of torque.

It is then paired to a mild-hybrid system, which shuts off the engine when the vehicle is stationary. Because of the new engine tech and the mild-hybrid system, Mazda is boasting about its high fuel economy figures. According to them, the SkyActiv-X engine in the Mazda 3 can do up to 25.6 kilometers per liter when fitted with a six-speed manual. With the automatic, that drops to 21.2 kilometers per liter. This is hugely impressive for a non-turbo, gas-fed 2.0-liter engine, especially one with 180 PS and 224 Nm of torque.
