I'm not even sure why cars like the Maxima & Altima are in this discussion

Back to the topic, the new G37 Sedan looks like it has little upgrades that are good enough for the wait.

.

 

G37 in Europe as the only engine platform offered is a big mistake. With gas prices nearing $6/gal and more, not many Europeans can afford that type of a car. Infiniti, should have offered a lesser version. Perhaps a V6 2.5L as well to cater to those who like but can't afford.

My 0.02

 

That is we are assuming it will be here,

FX is 35 not 37 as suggested/implied/speculated
So if you wait for 09 for 37 or even 7 sp auto, there 'is' a chance that it may not materialize

and on the max, it looks like the front is like the previous gen accord or even s2k minus the side slit on the headlights and the rear is the current gen accord

 

The 3.7 is the same engine as the 3.5 just with a slightly bigger bore and variable valves. My friend has the 08 3.7 coupe and I have a 08 sedan. And we have compared them, even putting them up on his car lift. There are hardly any differences between them. Every part of the motor is the same except the variable valves. SAME MOTOR DIFFERENT HEADS. And under the car the only different is the exhaust. I don’t think it’s worth waiting for the changes in 09 if there is any. Epically with the deals you can get on a 08 now. And the low 2.9% fin.

 

Will the the 09 sedan reintroduce the ip/graphite option? That is the major ? for me.

 

true that brotha. how could they get rid of this?!?!? i actually think i may have the only non-sunroof Ivory Pearl G35S 6mt on graphite interior in the United States. bring it back infiniti!!!

 

If you were buying the manual tranny, I agree 100%. Might as well buy now. The 3.5HR is a great motor.
That said, the 7-speed Auto should be a huge improvement over the 5-speed. If I was going with the auto, I'd wait.

I'm driving an 08 loaner at the moment. I'll be interested to see how the 3.7 liter feels compared to this 3.5. Will there be that much of a difference? The current one sure feels quick.

As for the new sport brakes, those brakes have been getting hammered by the various mags (C&D and Edmunds) for the their lack of fade resistance. Not sure if that's a major issue or just bad examples.

 

personally, I really don't care about an automatic regardless of how many speeds it has or how much faster it can shift over a human. I definitely don't want my left foot to get bored and hate giving up another skill control to a manufacturer...... the manual is the only way to go.

what matters to me is if the '09 3.7 makes more power/tq than the current 3.5 and the car itself is in the range weight wise as the RWD g35 sport 6mt is today. if it underwhelms on the manufacturer power spec versus reality, or the car weighs in like a g37 coupe or gtr, forgetaboutit. I'll keep my '08.

 

lol it be funny if nothing is changed for the 09 although all signs point that it is....

on my other R6 Forum, it had a dvd player, ac, and bunch of ther coo stuff LOL but obsioulsy it wasn't ..... = )

 

The G37 sedan will have more HP, but less torque

 

I dont believe so. History repeats itself. The sedan was rated at a lower HP in the earlier years, but many owners dyno'd their sedans and they were achieving roughly the same WHP as the coupe counterparts. Infiniti may advertise the 09 G37 Sedan as having less power, to have some sort of excuse as to charge more for the coupe, but we all know the 3.7L motors in both the coupes and sedans will be identical.

 

If they keep it de-tuned like the european model it will. Right now the G37 sedan has 258ft torque. Compared to 268ft for the G35 sedan. Is it capabile of more? Yes! Will they up the ponies and torque? Maybe. I don't know why they would hold it back. The only reason would be for better fuel efficience.

G37 sedan specifications in Europe are 310ps(305.75HP) and 350Nm(258ft torque)

 

10 less crank rated tq with .2 more displacement than the '07-'08s 3.5s? thats a head scratcher. how do the current '08 g37s 6mt coupes dyno versus an '08 3.5 6mt sedan?

 

I recall when the 1st dynos of the G37 coupes arrived. They showed a flatter torque curve and stayed higher longer, thus the extra horsepower. The gear ratios remained the same, so nothing gained and nothing lost there. The problem with the G37 coupe was that its weight jumped up too much so the difference between the G37 coupe and the G35 Sedan (306 HP version) was minimal if any. I imagine the G37 sedan will end up weighing a hundred punds less than the coupe so the performance will be similar, maybe a tenth or so difference. Infiniti needs to concentrate on getting the weight down on these cars. 3,700 lbs on the coupe is ridiculous. Even a couple of hundred pounds would make them so much better.

 

Here's one comparing the G37 to the G35 Coupe (not the same as the HR in the sedan which has 306 HP).

Being careful comparing different dynos.....here you can at least see the "shape" of the HR dyno. There is a relative dropoff at 7k rpm of the HR (210 lb-ft at 7k from 250 at 5k rpm. Still pretty flat. G37 dyno above shows a drop to 212 from 236). So, slightly flatter. It also seems to hit max torque earlier. Again, not looking at absolute values, just relative shapes.
