3.7L for G sedan and EX

So now the base engine in the G is more powerful than the upgraded engine in the 3-Series, and nearly as powerful as the V8 in the Audi S5, which costs nearly 30% more  :o  Speed junkies, your brand has arrived.

A G37 sedan is a really awesome package with surprisingly good reliability and a shockingly low price.  Still, something about the car lacks a certain je ne sais quoi for me.

An engine upgrade 2 years after the new 2007 G35 was introduced is reasonable.

EX37 right after the 2008 EX35 just hit the market?  ???
Is Infiniti pulling a "CX-9 engine trick"?

BMW introduced the E90 3-Series in 2006 and upgraded both engines in 2007.  It's been done before.

True only for North America, the E90 was introduced in Europe as MY2005, so technically it was still 2 years before the upgrade.

It's like saying the Fit was redesigned after just 2 years of introduction (in North America).

Yeah, me too.

As powerful as it may be, I just have a hard time getting excited about a V6. I've never driven one, but from all I've read, I'm left with the impression than Nissan's VQ-Series engines are a little rough around the edges.

For the money, I think I could put up with a fair bit of V6 blandness, but I wonder if I might regret not shelling out for the sublime smoothness and silky power of a BMW I6.

But Infiniti has, like, two engines, and the V6 goes into four different vehicles.  So no matter when they upgrade their V6, one of the vehicles is going to get it immediately after a redesign.

The VQ may not be silky, but it's not "bland."  I see the IS350 as "bland."  Great numbers, but not a lot of character IMO.  The VQ is harsh, but it certainly has a character all its own. 

And for the record, V6s can be awesome.  Ever heard the narrow-angle V6 in the R32?  What an amazing sound.  Put a nice exhaust on an A4 or A5 3.2, and you should get something equally beautiful-sounding.

My lack of excitement about the G isn't the engine.  It's something else, and I can't put my finger on it.

I'm willing to accept that not all V6s are bland, but please don't use VW's narrow-angle six as an example.

As far as I'm concerned, VW's engine is really just a slightly squished inline-six.  ;)

Then the real question should be, "Why didn't Infiniti just start off with the EX37?"
They had the 3.7 in the 2008 G37 coupe.

For someone who hasn't driven the G35/350Z, how would you know if it's less bland than the IS350 powerplant?  The IS350 sounds better, is smoother, and rips a bit more than the VQ.  I have driven both.  Multiple times.

What are you basing your opinion on? Just wondering...

No surprise here.  Love the sound the the VQ makes mated to the G35's exhaust.  :drool:  That said, I got some seat time in the G37 coupe at the autoshow and was underwhelmed.  Not much change from the G35, and I've no reason to think the sedan is any different.

I was much more impressed with the Caddy CTS, and although it might be down a couple HP, GM would likely get my money before Infiniti.

All reviews I've ever read of the VQ agree it's raspy, has very aggressive response to initial throttle openings, that it vibrates a lot at high revs, and in general is a bit of a bull in a china shop.  Now, that may be a character you dislike, but I don't think you can call that bland.

Likewise, reviews of the IS350 focus on smoothness, isolation, etc.  I've experienced the same engine in a different state of tune in a RAV4 and I've experienced quite a few different Toyotas over the years, being the progeny of two Toyota fans and married to one.  Like every Toyota engine I've ever experienced, the 3.5L is a smooth pussycat, but seemed very "distant" to me.  The 3.5L is a lot more powerful than other Toyota engines I've dealt with, though it doesn't get in your face while catapulting you forward.

Don't misread my post.  I'm not saying that the VQ is a "better" engine.  That's pretty subjective.  But the VQ is, by pretty much any objective standard, more "in-your-face."  And that's not bland.  You may prefer to have Clive Owen as a roommate instead of Axl Rose--and I certainly wouldn't argue with that--but that doesn't mean Axl Rose is blander than Clive Owen. 

Remember how this started.  I objected to V6s as a whole, and the VQ in particular, being called "bland."  It's like the guy who called the E46 3-Series styling "plain."  He may not like it, that's subjective and pretty hard to argue with, but it's not "plain."  If anything, it's complex to the point of fussy.  Now, the A4, I think that's pretty classy too, but that design (before the gaping maw grill) was very "plain."  Plain and fussy are not inherently good or bad, nor are bland and raucous.

Mits..Don't get me wrong, the engines are pretty close and both sound sweet....but the IS350 is smoother...less industrial than the VQ.  If I could make a weird comparison...the VQ is like an American V8, whereas the IS350 would be like a Euro V8.  Smoother, a bit more shrill sounding.  The VQ seems lower in tone.

I like the G35 (particularly the new G37 coupe), but I have NEVER been able to get comfortable in the drivers seat.  Whether it was the coupe or the sedan.  The seats just don't work for me....:(

Is the Nissan V6 60deg or 90deg?    for proper balance V6s should be 60deg ( or 120 but that would not fit into most engine compartments)

I notice that the M-B V6 is 90 degrees... may make for cheaper tooling but one would hope that M-B would make a proper engine.

Even thought it is rated at 330hp vs the 300hp for the BMW, the BMW has still been significantly faster in testing (than the G37 Coupe), to the degreee of .6 second in 0-60mph.  Thats pretty huge if you ask me.

True, but it'd be interesting to pit a G37 sedan against a 328i sedan again (the way Car and Driver has twice done in the past) and see if the Bimmer STILL comes out on top for a third time or if the newer engine makes enough difference. 

Didn't the Nissan-folks 'smooth out' and refine the 3.7 a bit versus the old 3.5?

328 vs. G35, pricing aside I think I would take the 328 (having driven both). The VQ was just a bit too in your face for me and didn't seem like it enjoyed being driven around town, whereas the Bimmer was happy to do whatever you wanted.

Put price into the equation and I would save the bucks and live with it. Would have to consider the A4/A5 though (interior and AWD).

Turns out that the G37 Sedan and EX37 are just for Europe:

http://www.leftlanenews.com/infiniti-g37-sedan-ex37.html

What I didn't realize was that the 330hp 3.7L actually has less torque than the 306 hp 3.5L.  Given that, I think that the 3.5L is better suited to the sedan and EX than the 3.7L is.

Are you sure?  At least with twin-cylinder engines, the opposite is true.  Ducati and Suzuki sport-twins have 90-degree Vs and are known for their perfect balance, whereas the Aprilia 60-degree V-twins require twin counter-balancer shafts.
