Mazda CX9 4-Cylinder Turbo Engine Explained 

Ditto to your points. Already a dedicated Mazda buyer with strong respect and appreciation for Mazda's true and innovative technology culture, this presentation by Mr. Coleman has me now leaning toward purchasing a CX-5 with the 2.5 turbo (GT Reserve) instead of the normally aspirated standard GT which I was previously planning to buy. Coleman is an impressive ambassador for Mazda.

Yamoto86 have you driven out yet? I did, and there only negative was the harshness of the engine during acceleration. So, I prefer to stick with my 2.5 n/a engine

FrostyCoug Thanks for the input. I currently have a 2016 CX-5 with 178,000 miles (not a typo). I've had zero mechanical problems with the car, so from my experience have very strong confidence in the durability of the 2.5 n/a and it's FWD. I'm impressed with and very interested in Mazda's engineering features of the 2.5T, but I don't have a strong need for the extra power and AWD, thus at this point I also will likely stick with the non-turbo (lighter weight, fewer moving parts and complications, etc.) for my upcoming purchase. Your input helped with that decision.

Yamoto86 I think you made the right choice. Fuel economy is mediocre on the 2.5t also.

It won't fit, sorry

When have they made a piston engine or any engine unreliable? The rotary engine just needed maintenance at a very early amount of miles on it, due to the nature of the engine and the seals that wear as they slide across the combustion chamber rather than metal rings. The turbo 2.3 engines had no issues, so long as you understood direct injection engines and did their maintenance, which was a pioneering effort [that I applaud] by Mazda (not to mention BMW and VW/Audi). Those engines and all engines since them, that have been direct injection, must have an internal cleaning done every so often due to buildup from no longer having port injection which took care of any buildup before direct injection came along. Cleaning could be done by hand, with a media blaster, or with the most friendly cleaner in a bottle, seafoam or similar product. I personally have over 250K miles on my 2.3Turbo Mazda which has had a bottle of cleaner run through it at every oil change. No issues, ever! Unfortunately, and to be truthful, Mazda never informed their customers of the required cleaning, although BMW did. So, I took it from the BMW guys, and mastered it. Shame on Mazda for not telling their customers, and letting us figure it out for ourselves... but they did swap out many engines under warranty without any hassles... unlike Honda and their failure to inform the customer of their nearly 100 thousand faulty engines & transmissions that they would fight teeth and nail to not warranty, yet they knew about it and still won't come clean (19years later)... hide it under the rug is Honda's motto. Never again will I buy a new Honda. I've learned my lesson.

@@copperkeyracing6167 Toyota Highlander 3.5l vs CX9 2.5l....which will last long in terms of miles or kms?

@@nikhilgaba1 Immediately, my mind quickly jumps to Toyota being the better engine... BUT, the reason I say that is because when you go to a junk yard you see sooo many Mazda engines blown-up/locked-up (connecting rod going through the side) due to carbon buildup issues, which come from poor maintenance on direct injection. [How do I know its carbon buildup that caused them to blow up? Because when you take the intake manifold off, the ports & valves on the head are sooo gunked up with this nasty black pasty stuff that you can barely put a pencil through the ports, let alone your finger. NASTY!] The Toyotas at the junk yard, all have good engines, clean ports, and the cars are there because of an accident, major one. So, naturally, you can quickly conclude that Toyota engines are better. They are not. Its all about maintenance. In fact, Toyota will not produce a car that has solely direct injection, they will require both port and direct OR just port. Never has, nor seems like will they, put a direct injection only engine into their vehicles. Same reason why they won't put floor mats that will slide and hit the pedals. Because, people are plainly not willing to do the maintenance and pull up on that floor mat, or do the liquid carbon cleaning method of maintenance to a direct injection engine. When the maintenance isn't done to Toyota vehicles, their pedal issues won't be a problem (not anymore atleast), nor will their engines blow up. So, with proper maintenance of the liquid carbon buildup cleaning on the Mazda engines, the Toyota engine and Mazda engine will last the same. 300k miles and above. Could be a million miles, could be half that, but 300k is the minimum with a well maintained Mazda/Toyota engine... and yes, I have seen Toyotas with half a million miles, and stories of some going to a million. Mazdas... well, half million... again, older Mazda, abused car=> broken engine. So, what Toyota does is very smart, they make sure it will last even if you are too lazy, so no matter what, their reputation holds. Mazda, smart to give you more power, better fuel economy, at a lesser price, but yeah, you better do the maintenance to have it last like a Toyota, even unmaintained. Conclusion: Toyota, but not really, kind of the same.

@@copperkeyracing6167thanks bro. Yesterday I was looking for the used 2018 CX9 2.5l turbo gasoline and same year Highlander 3.5l gasoline and was shocked with the price gap. The cx-9 touring was for 27500CAD and highlander base model LE was for 39000CAD and I am getting inclined towards CX9 for 27500cad which will save 12000-13000cad if I drop highlander for 39000. Obviously anybody will go for 27500cad cx9 even diehard fan of Toyota like me will drop plan for highlander when cx9 at such good price is available. What are your thoughts on this? Presently, I own Corolla 1.8l gasoline and the one thing for which I am worried is its cvt engine which has 109000kms and Toyota dealership says that cvt has lifetime fluid which doesn't need to be changed and this is undigestable to me.

@@nikhilgaba1 CVT transmissions are not good. I would be worried. They don't seem to last with any manufacturer. A normal automatic last longer. I don't know about specifically Toyota CVTs though... Between the CX9 and the Highlander, I would go with the CX9. Good luck
