: V-6 Vs V-8?

09-25-06, 11:34 AM
Many a good posts here regarding the STS. IF the cash incentives are trumped back up to the $7K+ range I'm considering a V-6 STS. Obviously the V-8 has more power but for a women (who has a lead foot) the wife might be better off in a V-6. She would be forced to keep the speed at a reasonable rate. I don't if the mileage would be that much better but there are MANY V-6's out there on the lots and my thinking is after Sept. dealers will be forced to deal. Any input on how much difference there is between the 2 engines would be appreciated. For I have NOT driven a V-6 powered Cadillac before.

I had the 3.6 engine in a 3500 lb. CTS and it was a great performing car. I currently have the 3.6 in a 4164 lb. RWD SRX and it is adequate. I also test drove a 3.6 in the 4130 lb. AWD STS and found it adequate. I found the 3.6 in the 4300-ish lb. AWD SRX to be lacking, but the V8 was fine.

THANKS c5. I too have been told the STS V-6 responded better than expected.

I have a 2006 V6 with 13K on it. I have been very satisfied with the power under all situations. Great low end performance around town and I have made a trip to Florida, 1600 miles each way. Still very good at 80mph and I got about 25.5 mpg. Not sure what the v8 will get.

I haven't driven the V8, but we've hard our V6 STS for a few weeks and I'm very happy with the power. The 8 might be a rocket, but the 6 ain't bad.

One vote here for the V-8. I already have another V-8 (1992 Mustang GT) and have been extremely happy with it, no problems in 100,000 miles, drives like its brand new, and gets 20 MPG city/hwy. Before I purchased the STS I was originally looking at the CTS V-6 Sport, test drove one, then noticed a certified pre-owned 2006 STS V-8 on the lot, test drove it, and there was no comparison. My grin stretched from ear to ear when I punched the V-8. I can understand your thoughts about your wife driving it, my wife has a lead foot as well. She currently has a 4 cylinder. By the way, 15K off the price of the 2006 STS V-8 because it was Cert Pre-Owned.

If I ever sell my truck, I'm also thinking CPO STS V8. AWD if I'm feeling "practical".

rb92gt: If you don' t mind me asking what was the sticker on your 06' STS and how many miles when you purchased it? THANKS. I think a 4 banger would prove to be the demise of our marriage however.

Take her out to test drive a Pontiac Vibe, then a Chevy HHR (tell her they are both popular wife-shopping-garage sale cars), and then a V6 STS. If she hasn't killed you after the HHR, the V6 STS will be a no-brainer. Or, maybe she will want a cheap mini-wagon and will spend the savings filling you house with OPJ - other people's junk.

GMBuyPower is currently showing $0 of incentive on an 06 STS. Am I missing something here? I'm talking new not CPO.

But you're correct. GM.com (GM incentive website) lists $0 cash incentive on the 06' STS. Somebody is wrong here.

I own a V6 since last November and recently had the opportunity to take the dealer's V8 on a day-long test drive. Summing things up: I'm more than happy with the V6. There's not much of a difference in power and the hefty price-premium for the V8 (at least here in Europe) all in all just isn't worth it. Besides, the V8 is about 10-15% worse when it comes to fuel economy...

Thanks straitcad. Sounds like the comparisons between the two engines favor the V-6 unless your into power.

Compared a V6 AWD STS to a V8 AWD STS (both '06s). V8 is faster, but the V6 is far from being a slouch. As others have said, nice low end torque. Shift it into the performance mode and it's a fast car. About a $10K difference in price over the V8 similarly equipped, too. That was enough to push me to the V6.

When I got my 05 STS V8 I recall the EPA BS mileage numbers were slightly better for the V8 than the V6. I wouldn't base my decision on mileage alone. I can tell you that even while cruising at 75 or 80, there is lots of room left and 80 to 100 is effortless.

For my 2006 STS V8 with Lux Pkg and sunroof paid 40,500. Had 9500 miles, certified pre-owned. Dealer put decklid and V mesh grill on for no charge. Being a certified pre-owned, I have a 6 year/100,000 mile warranty. If I would have bought a brand new 2006 at the time I purchased mine, only would have received a 4 year/60,000 mile warranty.
