What's the difference "strong" horses and otherwise? U mean having flat tq curve at lower rpm? Please explain.

Thanks

1. 335i surprise surprise!
2. G35
3. IS350 (VDIM, too quiet blah blah blah)

time to get a new car now.

Yep, the VQ is a great engine, but it's long in the tooth. Time for a new one, imo.

Ya, that'll be interesting. The 335is is dead flat from 1300-5000rpm. The graph is sick.

RE: fuel economy, I think the 335i will be better, but it's a guess at this point. It'll be close but I think the 335 will have 1-2 mpg better real life, we'll see. Won't be a huge difference anyway.

He means that BMW typically under-rates their engines, like they'll say an engine is 255/230, and it'll dyno 235/205, which is less than 12% drivetrain loss, or they'll say it'll do 0-60 in 6.5, but in real life it'll actually do 6.2. Lexus is often right on the mark (they'll rate 306 and it'll dyno 260, so 15% loss), they'll say 5.3 and it pulls 5.3's. Infiniti is kind of up in the air, some of their cars pull the numbers they say, and some (most) are a little less, like the 298hp G's that pull 230hp dynos.

Edit: got the graph:

WOW, that is some crazy torque curve right there. So flat.

That would be kinda odd if the new g35 only has 306hp. I remember reading somewhere that this g35 would be faster than the competition or something.

The VQ is getting old, but it's still one of the best out there. It is still very competitive with the new engines from other manufacturers. Just goes to show how advanced this engine was when it came out over 13 years ago.

Remember, the VQ is getting 300+ hp without the benefit of direct injection, which should add at least 20 hp. I'm not really sure why they didn't give it direct injection, since the 2.5 VQ in Japan already has direct injection.

with a 1000 higher redline and 80% new parts after making 298 hp, Id be disappointed if it didnt make 330ish hp

GFerg

Yea, I can understand why some people would be disappointed in that power ratingt, but IMO I think thatis fine. We all know the IS350 is damn fast for its class. Its kinda crazy that shortly all entry level luxury cars will be running mid to low 13's in the quarter mile(maybe even high 12's).

What I don't get is Nissans offer CVT and everyone has a 6 speed auto. If they auto had more gears, it would be more luxurious and faster.

I don't understand how this brand new car can have a 5 speed auto in 2007 when 5 speeds were introduced 10 years ago

As I predicted(and people burned me at the stake again), Infiniti is going to really push the "value/HP" proposition. Read here

I just completed the Synovate Research test/review of the new 07 G35 and let me say it is a very impressive car. I was invited to test the new G35 against the A4 2.0T Quattro, 325i, IS250 and TL. We drove each car and were asked many questions about the interior and exterior of all the cars. They were also trying to gauge the price point and option packages from us. Towards the end we tested the old G35 to compare it with the new one.

The interior of the new one is more upscale with much better materials and ergonimics. The location of the NAV screen is near perfect. The power from the V6 is amazing it made the TL feel slow and unresponsive. It also had very comfortable seats a bit better than the Audi.

Overall a good way to spend 3.5 hours and get $150 in cash for your time.
So
G35 vs
2.0 Quatrro, not the 3.2
325, not the 330 (or upcoming 35)
IS 250 (not the IS 350)
TL



Current G35 Base: $31,850
IS250 Base: $30,580
IS350 Base: $36,030
325i Base: $30,900
330i Base: $36,600
A4 2.0 Base: $28,240
A4 3.2 Base: $34,490
TL: $33,325

Those are the cars they tested based on price. But in the comparos that car and driver, road and track, etc will do, they will likely battle out the IS350, G35, 330i or 335i.

Manufacturers like to do this type of event based on different factors, sometimes it's price, sometimes it's power.

It seems that the purpose of this comparo was mainly to determine price points. There will be few changes to the car itself based on the opinions of the testers.

Infiniti knows that the volume sellers are the 325i, IS250 and the A4 2.0. Since there is no other smaller, engined version of the G35, these buyers are very important.

Clearly, the mags will test the G35 vs the equal power V-6 cars.

When automakers fight, consumers win

" Strong " horses, the way I understand them, is real-life HP that actually, from dyno testing, equals or exceeds the claimed figure. It can be either HP at the engine's output shaft behind the flywheel before it goes into the transmission or actual HP at the drive wheels. For most driving purposes outside of actual top speed on roads without speed limits like the Autobahns, torque is actually a more important figure, as it determines the amount of acceleration you will get. HP is more important in overcoming air resistance at high speeds and is more of an indication of a vehicle's ultimate top speed than what its dragstrip times will be.

oldcajun

When you consider the rumored 306 hp for the new G35, remember that Infiniti rates the auto engines lower than the 6 speeds. If the 306 hp is correct for the auto, than expect 326 or so with the 6 speed. If the 2007 weight is not up a bit, the car will be fast!
