What's Mazda's track record like with new engines?

Hello everyone,,
My wife isn't a car person but loves her M3 and the Skyactiv-X definitely caught her attention. I'm excited about it too, but I've always been very leery of the first model Appvalley CyberGhost ExpressVPN year for a new engine. I know they're already being tested, but we all know that's never the same as a proper production model. Trying to decide if it's worth waiting for a '19 or if we should start shopping now.

I'm still convinced you're a spam account but in the off chance you aren't (and because it's not a bad question to ask), I'll answer.

First, if your wife's M3 is an E46 or newer, she's probably going to be a little disappointed with a 3, regardless of motor. 333 HP V6 and RWD for the E46 makes it a completely different beast. Also, you don't have to get the Sky-X motor. The 3 will be available with the Sky-G 2.5L 185 HP motor (which is no slouch).

If you take the Renesis from the RX-8 out of the picture (and you should for many reasons*), it's pretty good.

The MZR motors (a.k.a. Mazda L-series, a.k.a. Ford Duratec series) are pretty good. Good enough for Ford to use as their primary 4-cyl motors for a long time. Same with the K-series motors.

Now, the Sky-X motor is a a very different design so it's tough to extrapolate their conventional MZR and Sky-G motor past to this new setup.

* The Renesis was created by Mazda's rotary enthusiast engineers in their spare time. I'm not kidding. Mazda wouldn't commit very much in the way of resources to the project. So, even though the engineers came up with some really cool ideas and got the power levels of the non-turbo 1.3L Renesis to equal the turbocharged 1.3L 13B-REW, they didn't do nearly enough reliability testing.
