Oops. With the lineup you listed I was thinking it was some GM model that I just couldn't think of.

What I think that Pontiac needs to go is to stop recycling all these antiquated FWD platforms and develop or borrow a RWD chassis, much like Cadillac has done with the CTS and is continuing to do with the rest of its line. People who buy Pontiacs want to have a little fun; if they wanted a cushy ride, they can go across the street to the Buick dealer. At the same time, these people are likely to have families or some need for practicality, hence they need a sedan, but want that sedan to perforn well.

When you look at the numbers, the 4.6L Northstar in the GXP is a little bit of a letdown. 4.6L is a significant amount of displacement, yet it only delivers 275HP - that'* 59HP/L. That would be acceptable if the car got phenomenal mileage, but it doesn't. It fairs only marginally better than a 400HP/369lb-ft 5.0L BMW M5. GM definitely has superior powerplants in their lineup: the LS1 and LS6 (and soon, LS2 and LS7, but reserved for the 'Vette). Granted, the LS V8s aren't as smooth and refined as a Northstar, but if a Cadillac customer can accept an LS6, a Pontiac customer should eat it right up. Also, if you read my post in the GXP/Northstar forum, I noted that the 4.6L Northstar in the GXP already makes a decent rumble, so I gather that an "opened" Northstar would produce the same amount of noise as a "damped" LS6, yet the LS6 would produce far more power and get far superior fuel economy.

GM has the tools to do it right, and they've pulled it off before. If they took the CTS-V chassis, dressed it up Pontiac-style and dropped the price ten grand below that of the Caddy, I would be the first person in line at the dealership. I understand there is also name-brand exclusivity, so heck, I would even go as far to say, let the CTS-V keep the LS6 and this theoretical Pontiac RWD sedan can have an LS1 or something. I'd still hit that.

I would, but I want four doors (despite being a single male just graduated from college ). The GTO is also curiously slow for how many ponies it packs.

Ummm... the above mentioned Jag?!?!?

Not to mention the Lincoln LS and others.

One of these days, Ford will re-introduce the Cleveland block, and shut ALOT of mouths...

A supercharged Jag with 390hp weighing over 3900lbs averages 18/28 vs GXP'* 17/24. I know! There is a huge difference in price (35Gs) but COME ON GUYS! Achieving a more competitive gas mileage rating shouldn't be asking too much for a $35G+ price tag! 17/24 with a supercharged GXP would be more understandable. I could definitely live with that because of the extra testosterone boost in torque and horsepower. Maybe it is just me, but what do you all think? I want better gas mileage like the SSEI with the V8 and I want a supercharged package to be offered. That would warrant my SSEI going back home to the Pontiac lot. If you don't believe the Jag'* numbers just check it out on www.edmunds.com under large sedans. UNREAL!!!
keep in mind the price tag for the Jag versus the GXP. I would say the GXP has good hp/$ compared to the Jag.

actually just to pick a nit here, the BMW M5 has a 4.9L (302 cid) V8.

The one biggest thing that GM MUST overcome if it is to be anything competitivie is to beat the awful resale value on their cars. Its so bad it almost makes buying a GM car a waste of money.While some GM cars do get decent resale( corvette, Esclalade, certain other Cadillacs and Chevys) the latest numbers on Pontiacs haven't been spectacular. The problem? If i bought a brand-new GXP ( i wish i had the money!) for 38 large, by the time it has about 25 or 35K on the odo, it would be worth only, maybe $17 or $16K . In my case, it wouldn't matter because I'd plan on keeping the car until the wheels fall off, but a lot of people look at GM cars and think ,hmm, great deal, yeah , V8..... but the (insert forign car maker here) is still worth something after 5 years. Jeez, this weekend i saw a used 2004 GXP with less than 5000 miles , and it was selling for $24,000! That'* a long way from $35 large or more new! Don't get me wrong, the GXP is a great car. Just .... dont want to see them waste away on used-car lots.
