Exclamation Loud engine?! *

Hey guys proud owner of a 2016 mazda cx-3 (US version 2.0L skyactiv gas awd)

I was wondering if you guys knew why the engine sounds so loud especially when accelerating... I own many cars including ones with direct injection (2016 honda civic) and it is nowhere near as loud. Do these cars sound particularly loud when cold? Any known engine related issues that I should be aware of?
I am currently using 87 octane, I have less than 10,000 miles on the clock. Car drives fine otherwise, the sound itself is emanating from the engine itself...not wind or road noise...

Thank you for any and all input!

It was noted in another thread but long story short the engine when cold will sound loud for the soul reason that the engine is trying to heat up the catalytic converter as quickly as possible. The noise is normal as all skyactiv engines will do this as well.

I noticed this as well right from the first drive. In my case the engine drones rather loudly when you give it the gas whether cold or warmed up. I actually rather like the sound!

My uneducated guess would be because of it being skyactive. They cut weight everywhere including sound damping/absorbing material? I noticed that versus my 13' focus, there's no material under the hood itself, that probably cuts a good part of the engine sound. Or maybe it's completely for another reason...

I haven't seen material under the hood for the last 6 or 7 cars I have bought over a thirty year span.
IMO the cx 3 is very quiet compared to the cars I have owned in the past.

The CX-3 has little sound insulation, that's the main reason for the loud engine.

I don't find the engine to be loud at all but I have never gone full WOT. I don't mind hearing some engine noise, keeps me in tune to what the vehicle is doing.

I still think the extreme 13:1 compression ratio requires significant de-tuning under extremely cold conditions.

Which is to say, my CX-3 prefers to be thoroughly warmed up before moving off ... if still cold, I drive as slowly, as gingerly as possible.

Compared to some cars I have owned, I do not think it is all that loud. A bit perhaps, but not excessive. Since I came from an Acura V6, I expected more noise from both inside and outside the car. Actually it is no louder than the Nissan Sentra SE-R I had in the early 1990s. That SR20DE engine could really scream.

Just got my CX-3 and was about to post about this. I like to warm my car up a bit before going anywhere and when it is sitting overnight for example, I start her up and it seems the engine is quite loud even when idle. Is this normal. As she warms up, she gets quieter.
