"the STS-V is certified at 469 horsepower, significantly more than the 440 estimated at the car's world debut earlier this year."

Yes, we know the numbers now, but it's a brand new article worth a post....

The 469 horsepower is confirmed in the supercharged Northstar project engineer's blog regarding his vacation with one of the first STS-Vs. There are some great photos of the car. See http://smallblock.gmblogs.com/archives/2005/07/supercharged_no_1.html#more

Very good report and 8820 miles in 17 days - excellent!!!!!!!

Thanks

That's a big boost in power over what they originally said it would be. Is the XLR-V going to remain at 440 HP as well? 469 HP, makes my N/A Northstar seem like a go-cart motor!

Now thats a road trip. Nice read. I wish the pics were a little bigger.

The XLR-V will be 443hp. However, since it only weighs 3100 lbs or so, it should go like stink. ;)

I bet that was the car one of the CTS-V drivers reported seeing in NY or NJ, I forget. said it was black, clear fogs and directionals...

nice link. here are some photos I've linked before.....

I wonder what the CTS-V guys think about all of this? I would think the STS would be faster. One problem I see is that the Corvette engine is a lot easier to work on and do performance mods. I bet the NorthStar will be to technical for us to work on.

Good points. Since the N* will not be mounted sideways maybe it won't be too bad? :duck:

I bet this engine will not be messed with too much. Except maybe boost level things, exhaust, etc..

If it's like the 3.6VVT you won't be able to touch the ECM. This is becoming pretty exotic stuff.:yup: That's why I think I'd prefer the small block Corvette engine of the V. They're getting 505HP out of that engine.

How much is the STS-V going to weigh? Any estimates yet?

Hi Ralph,
the weight of the CTS V is 3850 lbs, 400 lbs diff. to the STS V, but 69 horses more!!!

proabably more torque both peak and under the curve.

not 3100lbs. regular xlr weighs right above 3600lbs. With all that supercharger hardware i doubt it will hit 3100lbs rather it better be no more than 3800lbs

All I know is that ....that STS-V is a GREAT Looking Car. May be next for me!!:thumbsup:

I like everyting about the STS with the exception of the Bling Bling chrome headlights. I'm waiting until 2007 to see what the new CTS looks like with it's sheet metal changes. I hope they don't screw it up.:mad:

Holy CRAP. These horsepower wars between the US and Germany are getting ridiculous, and I LOVE IT!!!!!

Hmmm, thanks Harry! Are you concerned you might have to trade in for a faster car?

:hide: ;)

this would be the wrong thread to mention a Bugatti. :(

:sneaky:

soon brands like lexus is going to jump in with their hybrid motor to show up power and efficiency. (Toyota does have a few racing engines they can transfer over to the cars)

In retrospect the 3.6 is every bit a racing engine by design.

I meant an engine actually brought over from their race car. 3.6 isn't used in any races yet.

Not really, thats a whole differant motor than the 350-405 hp. It's 427-505 hp, with cnc ported heads, dry sump, and the list goes on. I think that this will be a good baseline motor, a little pulley change and 500 plus is just around the corner!

I'm talking about the design of the 3.6. It has dual overhead cams, variable valve timing, 4 valves per cylinder, aluminum engine parts, etc. Things that were only found in retrospect race cars. The 3.6 is a very high tech engine.

it's a very high tech without a doubt but technology found on the 3.6l is pretty much found everywhere else

list goes on and on and on. I think the reason LSx motor doesn't have one is because
1. it doesn't need one
2. adds cost
3. makes the engine package size big
4. adds weight
5. adds complexity

When I come back from Iraq and retire from the USAF and get a job that pays me $$$ and I get my wife's permission...well you see where I'm going with this, then I will get one of these:) WOW great article and pics of the STS-V it looks awesome. I'd take it over a CTS-V any day.

Anybody know if the 469HP NorthStar will come with an automatic? That's why I wouldn't get a CTS-V.:yup:

Anybody know if the 469HP NorthStar will come with an automatic? That's why I wouldn't get a CTS-V.:yup:

Yes, there'll be 6 speed automatic.

But does anybody know why are the power ratings higher for Europe? Look here (http://www.theautochannel.com/news/2005/08/22/141067.html) and you'll see this:

"European horsepower ratings are 476 hp (PS) for STS-V and 448 hp (PS) for XLR-V"

Is it because there is something different in the car or is it just the difference in measuring the power output in Europe and USA?

different measurement unit and different emission laws.

Also it's going to be available with 6spd auto only

The Northstar V8 Supercharged engine is the same for both Euro and American models. There is no difference in output.

An example of the conversion to PS is 469 x 1.0138697 = 475.5.

See http://www.onlineconversion.com/power.htm

When you see 476 hp or 448 referred to it has been converted from the SAE certified numbers.

Holy CRAP. These horsepower wars between the US and Germany are getting ridiculous, and I LOVE IT!!!!!

I'm not a big fan of Mercedes, but the S65 AMG has an ungodly 604HP and 738 lb/ft of torque. Still very shy of 469hp. (Then again, I don't expect the STS-V to top the $85k mark, so that puts it at about 1/2 the price of the S65.)

Now if Cadillac finally releases the sixteen, thats a different story.

Isn't the S65 around 180,000?

FOR RELEASE: 2005-07-28

2006 STS-V Reaches New Performance Level

Supercharged Northstar boosted to 469-hp


DETROIT, MI - Cadillac's upcoming 2006 STS-V not only enhances the performance of the current STS sedan, it also has eclipsed the goals set during its development. With testing now complete, the STS-V is certified at 469 horsepower, significantly more than the 440 estimated at the car's world debut earlier this year.

Performance testing for the STS-V has been completed at the Nordschleife circuit of Germany's famed Nurburgring, widely recognized as one of the world's most demanding tracks. The STS-V clocked lap times of approximately 8:30, a blistering pace for most any production vehicle, let alone a luxury sedan.

With production scheduled to begin this fall, the STS-V is the latest edition of Cadillac's V-Series, the growing family of vehicles expressing the full extension of the brand's performance and luxury credentials. The STS-V features the new 4.4-liter Supercharged Northstar V-8 engine and GM's new Hydra-matic six-speed automatic transmission.

The official power ratings for the 2006 STS-V -- 469 hp at 6,400 rpm and 439 lbs.-ft. of torque at 3900 rpm - are certified by the Society of Automotive Engineers (SAE.) SAE's new voluntary power and torque certification procedure (J2723) ensures fair, accurate ratings by allowing manufacturers to certify their engines through third-party witness testing. GM was the first auto manufacturer to begin using this procedure to certify power for its new engines.

The Northstar V-8 supercharged engine represents the most output ever for a production Cadillac. In the final stages of development, GM Powertrain engineers found more opportunities to push the boundaries of the Supercharged Northstar engine.

"Cadillac's V-Series is founded on the idea of taking the strong performance and luxury of our core vehicles and reaching even higher," said Jim Taylor, Cadillac General Manager. "The result is that Cadillac's V-Series family will consist of three serious performers, all going zero-to-sixty in under five seconds."

The Supercharged Northstar V-8 will also power the upcoming V-Series edition of the XLR luxury roadster slated for production in early-2006. XLR-V is certified at 443 hp at 6,400 rpm and 414 lbs.-ft. of torque at 3900 rpm. The Supercharged Northstar generates more peak power for the STS-V, compared to the XLR-V, due largely to the greater underhood space of the STS that allows more induction and exhaust capacity. On the other hand, the XLR-V will be a quicker car than the STS-V, given its superior power-to-weight ratio.

Cadillac is a division of General Motors (NYSE: GM). General Motors, the world's largest vehicle manufacturer, designs, builds and markets cars and trucks worldwide, and has been the global automotive sales leader since 1931. Cadillac products include CTS sport sedan, SRX luxury utility, STS performance luxury sedan, DTS, XLR luxury roadster, Escalade full-size SUVs and the high-performance V-Series (CTS-V, STS-V, XLR-V) three cars that go 0-60 in under 5 seconds.

If they picked up 26HP that easily the aftermarket upgrades should be impressive.

500HP and more torque should be a joke to achieve with the STS-V.

500HP and more torque should be a joke to achieve with the STS-V.

And 500 seems to be the magic number to achieve if they want to really earn respect among the automotive world, and media, etc.

Hey Ralph,
I just added to your reputation meter and here's what it's saying in FireFox:

Ralph is a splendid one to behold
:histeric:

After I hit refresh it went back to your normal meter bar.

LOL, I don't know dude, I haven't heard a girl tell me that in a long long time, LOL.

Don't worry, that "Road to distinction" is a lot more distinctive with a CTS-V!!:thumbsup: ;)

The points will be returned!
