The 2009 CTS-V will use the “LSA” motor. This is another new supercharged, small block V8. This new blown V8 will be good for at least 500hp.
A number of 515-525hp may even be possible, and even higher numbers have been rumored. The CTS-V will feature a supercharger integrated into the intake manifold. This is the same setup the upcoming Corvette SS / Blue Devil will have with its LS9 motor.
However, while the Corvette SS motor will be hand built at the Performance Build Center in Wixom, MI, the Cadillac’s LSA motor will be built in a conventional motor plant. Automatic and manual transmissions will be available, and an optional paddle shift feature is also anticipated. Production on the new CTS V-Series will start in September of 2008, and will be limited to about 7000 units annually. Internally, GM is referring to the car as “GMX322 V S/C.”
In the past, the current CTS-V has suffered from rear-end problems. Specifically, wheel hop. The 2009 CTS-V will feature a completely re-done rear end with a much better rear axle. Sources say this has eliminated the wheel hop issue altogether. The ‘09 will continue to utilize a massive set of brembo brakes up front and in back. While the wheels on this prototype are not production spec, the wider tires and larger exhaust pipes certainly are. Bob Lutz has been quoted saying the 2009 CTS-V “will be at a power level only described as unexpectedly high.”
Then referencing the current BMW M5, Lutz said the CTSV “will suck the doors off” the competition if the new M5 isn’t significantly better. After driving a prototype, Lutz said “flat-out incredible. I’ve never driven anything like that.”
The reason for the "freakout" on the wires is simple:
If the new diff is electronically controlled, there's no retrofitting it unless someone manages to write the necessary software to control it and make it compatible with our PCM.
Clearly I understand that we are talking about an electronic Differential and it's not just "wires". My simple statement here is that if people have been investing large amount of time and money to engineer custom subframes, and mounting Diffs that were never intended for the car, which in my opinion are pretty risky and involved procedures, then the statement that it will bolt in, but require some electronic customization to work is still a reasonable retrofit. Hell we don't know if it just operates in some default mechanical fashion if the harness is cut or fails(Which it must, as I assume if there was a failure it's wouldn't stop you dead. All I am saying is it would be nice, and seems like a reasonable option, as opposed to hacking the subframe and diff.
The engine is everything I could hope for in this new iteration. Hopefully, the powertrain is a significant improvement over the current configuration. The interior finish of my '04 will need a serious makeover to compete with the likes of a M5 and RS4 if that is the intended target.
