How many "boy-racers" see the turbo label and go out and buy one with too high expectations..? And then begin "modding" it with CPE CAI's, Hondata reflash and such and then question why the turbo fails taking the engine along for the "ride".

I would choose the EX35 hands-down. Why? Well let me tell you a little thing that irks me about Acura.. When you buy an Acura you are basically buying a gussied up Honda... Don't get me wrong, I love Honda, I drive a 2007 Honda Civic SI. Anything Acura is based off a Honda platform. The RDX comes from the CRV and the CRV comes from the Civic. Now I know what you are thinking, the Infiniti is a gussied up Nissan... Well i'll tell you why it is different. All of Infiniti's new cars are all truly sporty(except the QX56) because they are derived from the 350Z platform... So the EX35 comes from the G35, which comes from the 350Z. Seriously, I dont think the RDX is the same value as the EX35. And besides the EX35 is faster, gets better MPG, handles better, best safety rating in the segment, and I know someone will bring up Honda reliability but the EX35's engine has been a top engine across segments for the past 14 years. In the end where is your money best spent? A crossover derived from a RWD sports car or a crossover derived from an economy sedan?

Toyota, Nissan, and Honda all share a huge % of components between their regular and lux brands. No question there.
However, just to pick a nit, the RDX was designed first with the CRV inheriting many of the components, etc in its redesign.
Now, if you really think that all the Infinity models are "derived from the 350Z platform" then you have a world of disappointment coming your way. They pair up with their Nissan counterparts just like Acura and Lexus cars do.

I am not sure what RDX you drove but the one I drive is not under powered at all. Once you take some time to learn how the systems work together in real world driving you get a smooth, powerful, and very responsive SUV that drives like a TL. It corners like it is glued to the road and can play on the expressways with the best of them.
That said, I don't expect the RDX to drive like a sports car not do I often have the need to 'floor it' so if one is expecting that you might have a different take on the RDX.

All that you have said is very true but the really important point you missed was that Infiniti's are traditionally RWD or at least, for R/AWD, built on a RWD "base". I have heard that at least one of the upcoming Acura sedan is to be RWD....
Acura is current trying to climb one of the last steps on the ladder to being a fully upscale (read: knowledgeable and/or experienced buyer/driver) automotive manufacturer.

What I actually said was that the RDX is UNDERPOWERED until the turbo boost comes on line.
In order to accomodate the turbo boost pressure level once it "arrives" the engine is detuned/derated (<10:1 CR) from the "norm" for non-turbo DFI engines. A normal I4 with DFI (12:1 compression ratio) of this displacement could probably "loaf" along at a much lower RPM, fewer frictional losses. Another aspect of the detuning/derating design is it puts more "WASTE" energy in the exhaust manifold....notice how quickly the turbo spools up....and KILLS your MPG. RDX and CX-7 "turbo" equals POOR engineering compromises. Therefore the abismal hwy MPG.

I did misread then. My bad.
However, I don't consider 22 MPG (what I get in real hwy driving) on an SUV of that size and performance to be 'abysmal'. If it had the normal 2.4 making 170HP or something then I would be looking for more MPG. But for a 240HP/260ft/lb engine I think it is doing OK. Not amazing but not at all abysmal.

Abysmal in the sense that the larger V6 in my '01 AWD RX300 easily gets 22 hwy. And I understand the newer RX350 does even better than that.
I would have thought the smaller I4 would (should..??) do better since most hwy use would be off-boost.

I will give you that the Toy 3.5l is an amazing engine. I recall when they replaced the 3l in the Avalon with the 3.5 the power went way up but so did the MPG! It is smooth and enjoyable under all conditions.

Read ANY major automotive press review of any Infiniti except the the QX56 and it will say they share platforms with the G coupe and sedan, both of which share the same Front Mid ship Rear wheel drive architecture as the 350z. Only exception is the addition of All Wheel Drive in certain models. Take a look at the vehicle specs, their wheelbases and widths are nearly identical only different by a couple of inches. No Nissan other than the 350z shares any of the architecture with the Infiniti cars. Even the engines on the Nissan cars use the VQ35 while the Infiniti cars use the dual intake VQ35HR not to mention the engines in the Nissans (Altima, Maxima, Murano) are mounted horizontally and they are all front wheel drive.
