It's been a while since Toyota first unveiled the all-new Yaris, at least the one for the Japanese market. This thing is, the automaker didn't immediately release all the specs of it... until now.

Here's everything you need to know about the JDM 2020 Yaris in full detail.

There are three powertrain choices to choose from, which Toyota mentioned when they first showed it. There's a 1.0-liter, 1.5-liter, and 1.5-liter hybrid, all of which are three-cylinder. This time around, we now know how much power they all make. Also, there are a total of 12 variants to choose from so you're spoiled for choice...if you're in Japan at least.

The range starts with a 1.0-liter engine that makes 69 PS and 92 Nm of torque and the lone transmission option for it is a continuously variable unit. As for the trim lines, it starts out with the G variant, followed by the X but there is an X-B model which slots in between the two. Toyota claims the 1.0-liter can do 20.2 kilometers per liter in the real world.

Up next are the 1.5-liter variants and enthusiasts will be delighted that it still comes with a manual option, aside from the CVT. Despite only having three cylinders, the engine still puts out 120 PS and 145 Nm of torque. What's even more impressive is the fact that it doesn't use a turbocharger to extract that much power. In fact, that's more than the 1.5-liter mill in the ASEAN-spec Yaris and Vios which have one more cylinder.

The 1.5-liter range starts off with the Z M/T then Z CVT, followed by G M/T and G CVT and topping the range is the X M/T and X CVT. 1.5-liter models can be paired with all-wheel drive for as long as it's the CVT. Claimed fuel economy ranges from 19.6 (M/T) to 21.4 (CVT) kilometers per liter.

Last but not least are the hybrid variants and it's identical to the standard 1.5-liter range with Z serving a base, G for mid, and X for top of the line. No manuals here as the only way to shift the Yaris Hybrid is through a CVT. The hybrid makes 80 PS from its electric motor while the gas engine puts out 91 PS to give it a total system output of 116 PS. Fuel economy ratings are as high as 36 kilometers per liter, according to Toyota's figures.

With Toyota wanting to simplify their vehicle platforms, it is possible that we might get TNGA-B chassis Yaris in the future. It might even form the basis of the next-generation Vios as well. While there is a possibility that the Southeast Asia market could be a slightly different model, it is certain that Toyota will utilize their latest architecture as much as they can.
