I tend to agree, however the VQ is so much more rewarding then the VH, because of its ferocious midrange power. That is something the VH always lacked.

That's why the VK is the best of the three, it had the best of both worlds.

You must have been driving a sick VH. Mid-range to high end is where it dominates, and the VH45DE matches the VK powered F50 on the highway.

I have often wondered what a OBDII managed VH45DE would do.

The VH is good at top end. It's virtually dead before 4,000 and the 90-93 esp is really good from 5-7k

The Z has much better mid range that is 3-5,500 or so.

The VK will easily outrun a VH unless the VH has JWT

Go drive a M35. Two tons and still has much better low-to midrange, but yea the VH is good on the real top end of things.

The 94+ not so much, but the 90-93 with the twin hp peaks comes alive after 5,000 rpm

5,500 is not midrange that is top range. Mid of a 7,000 RPM car would be 3,500.

The VQ has a much more user friendly powerband, you don't have to rev the hell out of it like the VH.

It's much more rewarding then any Q ive ever driven including the one with the modifications

Ryan I think we're comparing apples and oranges. I do agree that the VQ has more midrange power, but it also, worst case scenario has a 5 speed aut. The Q has a 4 speed granny box...

Put a 5 or 6 speed behind the VH45 and tell me it wont outrun the VQ or even maybe VK!

I think its more then a simple transmission. I love the VK, the few times ive driven something with it in I've had much more enjoyment then the VH

Just ask an yone on here who owns that has also driven a Q. I'm sure Z would say his M is far more rewarding, do you think it's just a simple transmission issue? It's more efficient lighter engine with full VVT, better ecu, etc etc.

I like higher revving engines. The new Audi RS4 V8 revs past 8k rpm, but has most of its torque after 2,000.

Or of course the last M3 engine, a thing of brilliance.

Just like the VH the VK is wasted because its never been mated up to a manual or put in something lightweight and sporty.

The real-world situations where you want the V8 are towing or carrying extra people and luggage. Driving by yourself to and from work, it all boils down to sensations -- many drivers notice; some don't.

What about packaging issues, weight, and space efficiency? I too would like to see a new 450Z.

hmmmmm, $7000 I would take the v6 since more aftermarket parts are avail and eat the v8 all day.... I like the v8 but I like Mods, not much mods for the vh or vk at the present moment..... imagine a twin turbo m35 sounds sweet....

The Audi V8 is an undersquare design, good for torque and emissions, not so good for top RPM revving ease. The Gallardo V10 and the RSX and S2000 fours are also undersquare designs, but champs of piston speed by necessity. I prefer a nice over square. My favorite domestic V8s were the Ford and Chevy 302, 4" bore, 3" stroke.

New M3 will be a 4L V8. Probably a screamer that will challenge Ferrari/Maserati.

Reprogrammed 5 speed automatic and ECM/VK45DE is drawing rave reviews from test drivers and owners over GS430 with 6 speed automatic.

I'm talking about the new RS4 V8, which is not really the same thing at all as the reg v8. that's like comparing the m5 v8 to the 540i v8.

The new V8 going in the RS4 is an absolute monster, and it's a high revving one at that.

That it is, but still undersquare, I bet. Haven't seen a technical break down yet. I think they finally went to chain drives on the camshafts.

Fellas, you know much more about engines than I do....all I can say is I got the V8 today, and OHHHH YAAAAAA!!!

Gas milage is gonna hurt though...averaging 12 mpg so far...

Well the AUDI RS4 V8 makes its peak horsepower at about 8,000 rpm or so. It's definately a high revving engine, and enjoys being such.

350zQ45a wrote:Look the V6 is a great engine, and you really won't notice much difference unless you're applying wide open throttle.

Sorry, can't disagree more here. The V8 is not about wide open throttle. It's all about the torque, the gobs and gobs of low end torque.

Even at a light throttle tip in while on the freeway or around town, the M45 scoots even before downshifting, and that's what makes the car so much fun (along with the superb handling).

It's like comparing a literbike to a 600cc bike. The 600cc bike is mad mad fast at WOT, but what I like about my Yamaha R1 is the torque that's available at any RPM, that I can be cruising in 6th on the freeway, flick the wrist, and it just effortlessly rockets to 100mph without even a downshift.

Sure, it's nice to have the increased WOT power, but you're only talking about 45hp or so? Not a huge difference in a 4000lb car, especially with the increased weight of the V8 (100lbs or so?)

It's all about the Torque!!

(BTW: Picked up an M45 Sport for my wife on Saturday, drove it from SoCal back up here to NorCal, over 1000 miles on it and loving it already. I'll post my review/comments once I get the bugs off and get some pictures taken).

Wow guys, just read every post in this thread... You guys own beautiful cars - congrats. I only dream of one day driving a vehicle like that.

Look how far Infiniti has come from my 93 J30 Haha, who would've thought!

it seems alota people are sayin the 3.5L is not worthy in the M cause it doesnt have the TQ or upper range. To someone who actually wants to mod his M35, say bolt ons at first since so much is available, wouldnt it vastly improve the 3.5 motor pushing its numbers over the 300HP/TQ mark if not close too ? and with the 100 or so lbs difference (not much) both cars would be pretty damn close even though the M35 would be tryin harder ? I mean theres wat $7000 (?) difference between the 2 cars, I think 3.5 motor with $5000 in mods would be as fun if not more fun than the V8 ($2000 would be spent on dropping it...) but thats just my opinion...

There is no doubt that the M35 could be brought close to a stock M45 in power and torque, with enough add-ons, or even exceed it. Yet, it is the smooth availability of power in the M45, with a sense of unlimited power on tap (of course, this is not true, but it just feels like it ) that leads many people to splurge on the V8!

The engine simply feels less strained and concerned about things. Rushing to high velocities becomes that much more fun.

Note that I would happy with either car , but, if I had my 'druthers, I'd get the M45!

I would have purchased a M45 if they had offered AWD as an option. It snows here so we decided the safety factor was more important than "gobs of torque". Maybe when our lease is up there will be a M45x (I hope...)

Clearly, that is a definitive and good reason for your choice! My wife is also considering the M35x as one of the alternatives for when we replace her car (we keep saying "soon", but her current car is still running well, so we have been putting this off for three years now!)! For her, the power and torque in the M35 six-cylinder is way good enough.

That would indeed be very, very nice
