#2 of 36 07 LTZ Power by vanman1

The 07 Impala LTZ has a little less HP than the 06, anyone know if the 0-60 times have been affected? I am a little disappointed in this change for an extra 1 or 2 MPG.

I would guess that 0-60 times will be similar to '06 models. Most comments on '06 Impalas indicate that the 3.5L and the 3.9L have very similar 0-60 times (the '06 3.5L has 211hp and the '06 3.9L has 242hp). The 3.9L, of course, has more punch for passing and climbing hills.
 
For '07, the 3.9L has dropped to 233hp, only losing 9hp from last model year (torque is only down 2lb-ft for '07). The power-to-weight ratio only changes by a little more than half a pound (14.68lb/hp vs. 15.25lb/hp). In my opinion, that alone shouldn't be enough to significantly change the acceleration time.
 
Unfortunately, car magazines tend to bypass the mainstream Impala trims (LT, LTZ) in favor of the SS when they do reviews and instrumented testing. It would be nice to see one of the major publications perform road tests of the top selling trims instead of the performance variants.

Thanks for the thoughts.
 
I like the LTZ best, it's a nice compromise on power and features. Torque is more important than hp but every one looks at hp.

#5 of 36 100,000 mile warranty by kw5kw

Having driven the '06 and an '07 I preferred the new 100,000 mile warranty that the '07 now has.

The new warranty is a 5yr or 100,000mile (whichever comes first) powertrain warranty. Most people will not drive 100,000 miles in 5 years. Average is 60,000-75,000 miles. So, you would most likely only be gaining an extra 24 months of coverage.
 
I would rather just take the savings on a leftover '06 with the 3yr/36K warranty. If the car turns out to be problematic, you could always buy a GM sponsored extended warranty before the 3/36 ends and still come out ahead versus paying more to start with for the '07 model.

Here are two cool links for all the baby boomers out there:

The old 409's were fast for their day (early '60s) but were also very heavy and had two four barrel carburetors that had to be kept carefully tuned. Today's Impala SS has electronic fuel injection that's much more efficient. The result is a faster car (0-60 less than 6 seconds) delivered from a small block V8 engine, although purists won't acknowledge a FWD car as a being muscle car.

Just muscle in a different application. Torque steer is a challenge to overcome just as positraction inducing the rear-end drifting to the right was a challenge to correct for. However, there is something to be said for the torque flexing through the entire frame of the car and the sensations of having the front end lifting and the rear end dropping, full-throttle power shifting with or without the clutch, and the guttural lumpy rumble of a long-duration high-lift wild overlap cam trying to find an rpm to idle.

Hi clark & jpstax...
 'Ya, I guess I'm considered one of those good 'ole rear wheel muscle car purists that you are refering to. But, you know, I'm not going to get all in a flap about this here and go on and on about this like some do...Wow, maybe there's finally some maturity here... Hey, although different, I feel that today's '06 /'07 SS Impala, and all that it intales, is one mighty-fine piece of performance machinery!!
Ohhhhhh Memmmmmmmories..!! Yes sir reeeeee bob... I can definately still remember sitting at those stop lights in my machine feeling that lumpy long duration / high lift solid lifter cam...Oh boy..!!
          Thanks for taking me back....!!
