I am def just speculating rite now...but when i think about it it sounds like it could be pretty possibly. With the confirmed announment of the g37 and the new motor, i think its pretty inevitable that inifiniti will put that motor in the sedan by next year, following bmw's 335 steps. I wonder if infiniti will start offering mulptilpe engine choices the way beemer does, or even make the g35sedan come with the 3.5 in base trims, and the 3.7 in the S trims.

Like i said just speculating but sounds cool lol.

 

makes sense... but they did dump a ton of money into the 3.5 so they would need to find a home for it... im guessing in the rest of their product line (maxima,altima,etc)

something like this im sure they thought about, and changing an engine on the infiniti a year later , uh dunno. but yes on the S model I could see them adding the 3.7

unless they want to seperate the coupe substaintially from the 4dr... which is a possiblity also... slap a new set of springs do a few engine mods and the 4dr was faster then the coupe... they needed something to seperate it further.

ppp

 

Engine mods aren't really necessary. Apples to apples, the sedan is faster out of the box.

 

Marginally so, the difference being almost imperceptible.

As for the engine, I will bet good money that the 3.7L will wind up in the sedan some time after the coupe is released. The names FX37 and M37 are already trademarked, so I believe the 2008 models of each will receive the new VQ37HR while the VQ35HR will stay in the Altima and the 2008 models of the Maxima and Murano. Just speculation of course.

 

It does seem logical that they would offer the 3.7L in the Sedan Sport model. I've always thought it was kinda lame that the differences between most sport models & non-sport is mostly aesthetic.

On the other hand, it also makes sense that Infiniti would want to completely differentiate the coupe engine from the sedan.

 

How so? I can agree with the differentiation of appearance -- coupe owners want their car more dramatic and sport-car oriented. But, the whole point of the G is a good mix of sport and luxury. By only having the 3.5 in the sedan, that would lead people to believe that it is slower than its own coupe brother and hurt the cars perception of being sporty (to average buyers). So, Infiniti would have to make it markedly cheaper than the coupe (booo, no expensive coupes!!! ) to explain the "weaker" engine.

If they are trying to up the ante and stay close to the 335i (which everyone loves to talk about), it would make sense they would dump the 3.7 in the sedan as quickly as they can. After all, the sedan owners what the same performance, just with a bit more practicality. Why not give it to them?

Now, having two engines in the line up (ala the M) makes some sense as well. Especially if the G35 starts around $31.5k and the G37 $33k. The only reason not to would be if the difference in power wasn't all that "noticeable." 20-30hp isn't perceived to be that much for a 3500# car.

Besides, I can't imagine it costing all that much more to produce the 3.7 over the 3.5 (though I could be wrong), so why not?

 

^+1

why not...

1. they wont have to tweak 1% more HP out of the coupe engine to make it show faster on paper
2. 3.7 may consume more gas then the already thirsty 3.5. the 4dr is a sport/family car and getting better gas mileage is slightly more important then power.
3. changing the engine 1 year later will alienate the 2007 4dr owners
4. the 2007 will be the red headed step child = resale hits the floor
5. infiniti parts will be limited.

I'd like to see them produce better gas mileage with the new 3.5 and offer an option of the 3.7. this would keep both engines in the lineup while providing what the customers ask for luxury with gas mileage and luxury with performance.

ppp

 

hope the 3.7 will have direct injection!

 

I hope too...

but would bet against it every time .


ppp

 

Im pretty sure it will to keep the gas efficiency in the 3.7. Direct Injection improves gas mileage a lot

 

What's the obsession with naming the car after the engine size? Why not just call it the G35, a well-known name, and put a 3.7L engine inside and call it a day?

I guess I'll never understand why they do stuff like that.

 

I agree, G37 doesn't sound right... I guess I have to get used to it. I believe the G Sedan will get the 3.7 in 08 and the Maxima, Altima, Murano, FX, etc will get the 3.5 HR.

 

The names FX37 and M37 were tradermarked at the same time as the name G37, as stated in my above post. The 35HR will likely remain in the Nissan line, and the 37HR in the Infiniti line.

 

It gives people more of a reason to buy a newer car, and is an obvious indication that the new car is more powerful.

I know it sounds ridiculous, but most people are ignorant about displacement and all that stuff. But, they know 37 > 35.

Heck, that is probably the one reason they put the 3.7 in the first place -- to combat the perceived "reduced" performance in comparison to competitors.

It's all marketing.

 

It may not roll off the tongue very eloquently, but rest assured people will be singing its praises after some time behind the wheel....
