Thanks for the review.. But I'm referring to diesel.. Prior to this, used to pump mostly Petron and later Petronas (cuz cards purchase savings) for my previous car and both fared okay. Petron fared better in terms of performance and fc. Bare in mind, this was with an extra tuned car..so I believe that the engine plays a part too.
Because if you can tahan the 2.0 GLS power delivery, then no point getting the 2.5 as both share the exact same specs.. Just engine different. You get the 2.5 if you can live without the extra specs of diesel and or its engine, but want significantly better power delivery than the 2.0. Another would be that others come with 19" rims and tires that IMO, looks better. Of course, replacing the tires will cost mor later over the 17". Non-issue here.
Went for the 2.2, not for FC..but this helps as previous car had an avg range of 350km.. So getting twice that is already a plus. Got the diesel purely for its power and additional features (which IMO, worth the extra cost..the difference between it and the 2.5 is..what.. RM4k?)..Even the full circle color LCD was important to me. I'm sorry but my mini-OCD won't be able to stand looking at that rectangular screen daily for years. Coming from a rev happy fast car that only struggled on certain hills climb and overtaking. We wanted something close to the power delivery and driving dynamics of the 5 series MS, but in the practical SUV form. The CX-5 is no match but comes damn close. Plus it's Japanese (more reliable than conti on avg) and is recognized as the best diesel engine in the world. So far, there hasn't been a hill climb or overtake where it struggled.. With or without full load. Just last night, even managed to overtake a "struggling" 2.5 that graciously gave way on the right-most lane. You would be surprised how many cars don't think it's a fast car, only to watch me pull away.. Can go toe to toe with an AMG (forgot the exact model) some more..
Lastly, with the diesel, I don't have to deal with the incessant droning and whining of the petrol engine as it tries to power up.. Even at 150km/h, you'll see the needle hover around 2K RPM and you'll barely hear the engine. Step on the pedal some more and it'll still pull with little effort and remain stable. At such points, I become concerned about surprise road bumps than the car itself..

As you can see, we wanted power first.. Always.. Doesn't mean others don't have sufficient power for your needs. Just for ours, we wanted
effortless power delivery and handling. That was our top criteria for purchasing a new car that trumps the older one. Would have gone German or Swedish, but you know, I know, what people say about conti cars and expensive repairs.
