O.K. this is to be taken with a grain of salt. I question this source greatly. These 3 links show weights and 0-60 times for 3 cars and goes as follows:

1. 1997 Pontiac Bonneville SSEi http://www.edmunds.com/used/1997/pon...av..6.Pontiac*

2. 1997 Oldsmobile LSS supercharged http://www.edmunds.com/used/1997/old....6.Oldsmobile*

3. 1999 Pontiac GTP http://www.edmunds.com/used/1999/pon...av..6.Pontiac*

Acceleration (0-60 mph): 7.4 sec.

Not tooo shabby for a 3700 lb car(although I personally think it is a little faster than that)!!!

Yea, but the reason I question it is the LSS is an h- body. So how can it weigh almost 200lbs less!?! If its true, then thats cool i'm almost as light as a GTP. It just always confused me why Bonny owners say their cars weigh 3700lbs when my LSS only weighs 3500lbs. :?

Final drive gearing have any effect on this? :?:

You might want to consider options weigh alot. There are alot of thing that your LSS dosnet have that a Bonne does. 12 way power seats, all of the extra electronics, ELC and pump.

IT all eventually adds up

Y'know the Bonneville isnt' the only car with all those options. If I were to venture a guess I'd say the LSS might have moreoptions than the average Bonneville because more things were standard.

You sure the LSS didn't have ELC and such? I remember seeing air shocks on a dead 88-91 Olds equivalent in the junkyard, so newer models not having it would slightly surprise me. And, being the top dog LSS, I'd be surprised if it didn't have power seats. Power seats are heavy, regardless

Yup, the LSS has more standard options as I suspected. It makes sense, Oldsmobile and Buick are/were the conservative luxury brands of GM. Pontiac is more of the "extreme" sporty brand. The bonneville combines both sportiness with luxury at the same time (as far as the lower brands of GM go anyway. They reserve the best for cadillac.

Ok.... I'm going to have to take those #* with a big grain of salt.

7.4s for a 0-60.... is anyone thinking that'* really really high?
Maybe for the NA, but an SC.... should be more like 6.5s

Using this timeslip from an 99SSEi
http://www.dragtimes.com/Pontiac-Bon...slip-4312.html
(btw... this was a members car... he sold it for a gold sse... see if you can name who it is)


and this online calculator....
http://www.wallaceracing.com/0-60_equation.php

It yields the 0-60 time to be 6.2seconds.... give that a 1/3 of a second for error, and you're still only at 6.5seconds.

The times for that 99SSEi are slower then my 97SSEi, which I ran stock.
Sorry to say my timeslips do not provide me with any 1/8 data. :(

actually... hate to say it, but 7.4 seems kind of fast. STock our 00' SSEi was 7.6 seconds and I know GTP'* and Regal GS'* are 6.5-6.7 and they're a lot lighter than a Bonneville is and also have more aggressive PCM programming. Stock I also ran mid to high 7'*.
