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.

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.

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

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.

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.

Replying to: cnw (Mar 13, 2007 4:33 pm) '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....!! Frank
