2006 Cadillac STS-V
information on the new STS-V
http://media.gm.com/events/autoshows...0overview.html from motorsportscenter.com "The supercharged Northstar V8: 4.4 liters, 440 hp, 430 lb-ft of torque - 90% of which is available from 2200 to 6000rpm, and VVT. This supercharger is worthy of special note - engineers were happy to tell us that this blower operates with some 30% less drag than the Ford GT's supercharger, and the intercooler has 50 cooling fins per inch length of the pipeline."

2006 Cadillac STS-V now rated at 469 hp
2005-07-28 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.

I think that the V-Series (STS, CTS and XLR) are good, but not good enough for the worlds largest automaker top of the line brand.
I still don`t understand why the sixteen and cien didn`t make it into production. Ford has his GT some Jaguars and the whole Aston Martin Brand, BMW had the F1 and now the M5 and M6, Mercedes got the SLR McLaren and many other AMG cars and we better not start with the italians. My point is why GM can`t make a true supercar, many other smaller brands have done it, and there was a time when I started to think "why they can`t use more than 8 cylinders".

BMW didn't make the McLaren F1. They built the engine for it.
Perhaps Cadillac is waiting to see how the new STS-V and XLR-V sell around the world before they make a production Sixteen or a Tweleve (for V-12). I didn't get to sit in the new STS-V at the L.A. auto show, but I was impressed with the new XLR-V when I sat in it.
