I wonder if you got the “better” engine, or the same engine with cylinder deactivation with a software tweak to make it so the CD does not kick in?
Mazda has to modify and add too many components in engine、transmission、and even the exhaust system to make the cylinder deactivation work properly. Due to the cost reason, Mazda won’t use more expensive CD engine with the feature totally disabled on the lowest trim model. Keep using an existing reliable and cheaper non-CD 2.5L engine makes business sense.

yrwei52 you are correct, the Canadian Kuro does in fact come with cylinder deactivation. It's kind of confusing the way the Canadian site lists cylinder deactivation for each model. Can't see it listed for both the CX or Kuro. It's definately listed for the GS. Under the Kuro it states "Skyactiv-G 2.5 L DOHC 16-valve 4-cylinder engine (187 hp & 186 lb. ft. torque)" and nothing about cylinder deactivation so it's a bit misleading.

Mazda sold many vehicles with the Skyactiv-G 2.5 L DOHC 16-valve 4-cylinder engine without cylinder deactivation. I don't think they would want to waste a single penny on parts that aren't necessary. I checked the parts at the Canadian dealership before buying mine and for 2019 Mazda sells a head and components for cylinder deactivation and one for without cylinder deactivation. The dealership thought I was carzy for not wanting cylinder deactivation because it saves fuel and was only available on the lowly GX model.

Today you can buy a USA CX-30 without cylinder deactivation.

What Engines Are Available in the 2021 Mazda CX-30?​

The base SKYACTIV®-G 2.5-liter four-cylinder engine delivers a class-leading standard horsepower rating of 186 horsepower and 186 lb-ft of torque. In most cases the standard engine delivers up to 25 city / 33 highway mpg for models with FWD, or 24 city/ 31 highway mpg with the i-ACTIV® AWD system. The exception to this formula is the Mazda CX-30 Premium AWD, which has a cylinder deactivation function and averages around 25 city / 32 highway mpg.
