For the first part, you're right on. The EX35 has the VQ35HR. The EX37 has the VQ37VHR. That second V makes a big difference. It signifies the presence of Nissan's highly advanced VVEL (variable valve event and lift) tech. The 3.5 gets traditional CVTC (continuously variable valve timing) which actually works alongside VVEL as well in the 3.7. But the 3.7 has a very advanced valvetrain...one of the most advanced designs in the world. The 3.5 is much simpler and more traditional.
As for the second part, there is indeed a reason, but I don't think it's the one you're implying. The M kept the 3.5 because it was not an all-new model at the time the 3.7 was introduced. Integrating the new 3.7 would have meant a lot of re-engineering. Keeping the 3.5 was simpler and cheaper. And the all-new M next year WILL abandon the 3.5 in favor of the 3.7. It'll be M37 or M56 (VQ37VHR or VK56VD). Even the gas-electric hybrid M will get the 3.7, not the 3.5.
The FX and EX I have no idea. Europe also gets the FX37 rather than the FX35. I wonder if it's related to CAFE and fuel economy?
if you take it from a marketing stand point it's pretty sound logic i think.
Infiniti and Nissan has had an established image in the US. on top of that, with the introduction of the VQ35DE in the 350Z in 2003, this engine has gained immense popularity.
Truthfully, the CUV segment lacks in the direction of displacement + power...i mean what's the next closest? RAV4 v6? well for 2010 it's the SRX 2.8T @ 300HP, 3HP more than our current mill, so you can say the USDM has just caught up to the EX in the CUV segment in terms of power.
second, i mean, if u were nissan, wouldn't u milk all u could get out of a cookie cutter mill? why introduce something new when old works? when "new" can be put aside for later?
on top of that, Infiniti as a namebrand has not been very well established in Europe, so they tried to be competitive, through in the VVEL 3.7 and branded infiniti on par with Bimmer, Benz, etc. Unfortunately, if you ever read the british reviews of the EX37, the design is so....NOT european, that they actually didnt pick up as well as intended. - to them, cookie cutter is Q5 design, which is elegant, albeit not beautiful.
Right now Infiniti in the UK is pushing so hard, i wonder if they are losing more money than making currently in their marketing strategy. some of THEIR Perks include any service that is due, the dealership COMES to you to pick up car and provide loaner, you have a personalized sales associate who exclusively works with you during the duration of ur ownership (i think the small letters also mean as long as the stnd warranty applies LOL)
so it's not hard to see why they threw in the 3.7 powerplant. alot of cars in EU end up with better performance and options vs. the american version....look at FORD in the EU, the Focus RS? seriously?!!? or better yet, the Audi TT RS vs the American Audi TT S
now those are different segments in the field, let's just look at the CUV segment...we have almost no competition. let's be realistic, not from a buying standpoint but from actual comparable data. (meaning things like the CR-V, RAV4, CX-7 dont get to play because even though their price points are very close they don't come close ....ALTHOUGH the CX-7 does have alot of the amneities that the EX offers too) - other branded CUVs like the Edge and Subaru are simply a lot bigger and really are small SUVs not compact UVs
the real competitors of the EX35 are the SRX, RDX, Q5, GLK, X3 - all with the EX35 with the second most powerful powertrain, and also being on the market longer than the SRX that beats it with 300HP. If you look at it this way, i'd say infiniti is ahead of the game. SRX is 2010 model, let's just say end of 2010, or EVEN 2011, right around a Model year cycle refresh for the SRX who continues with the 2.8T powerplant, Infiniti throws in the EX37.....even without a model update (for looks etc etc) it woudl still outclass the models in its class (the only contendter is a GLK AMG or a Q5 performance variant Q5s? lol) or X3 M...god forbid
so with that point of reference i believe infiniti has a few options available, vs well their competitors
and then we look at the EU market again...they have the X1!!!!! and X6 (which we do too) the EUDM is simply oversaturated with options from US, EU, and Asia, vs the USDM.....esp for a market like the CUV where space has been scant in EU while in the US it's been a economic/preference/trend thing
just my $0.02
