Came up to the lights,had just turned red,looked to my left,traffic still stationary,and made the turn without stopping.Before I could get fully straightened out in the lane,this Caddie blows by me and keeps going.I only heard a slight roar just as he passed me.Those caddies are smokin' fast.The 556 hp supercharged machines have been comparing very favorably to luxury European makes.

The new ZL1 Camaro will have the CTS-v's 6.2L LSA engine...as well as the ZO6's tuned performance quad exhaust so bhp should be over the Caddies 556. I still like the Boss 302 though...its tough to beat.

some of those cars can give my cbr 600 a run for its money for a short time in a straight line for sure.

haha you wanna feel speed you should try being in one! My dada bought the 2010 CTS 4 in fall of 2009, which was his first car in like 20 years. He thought it was ok, had like 286 HP rollin in the v6, But he is quite the car guy so in the fall of 2010 he traded his CTS4 in for a CTS V, i can assure you its quite spectacular! he took me for a small ride just after he got it and i was almost sharting everywhere! haha cruising on the highway 100 then just giving it some gas and you watch 190 appear >_<

The CTS V runs the exact same motor as the Corvette ZR1, which makes the Z06 look like a toy. The ZR1 has 640 HP and lists out for about $160 000, so the motor has had a couple tweaks of the chip and it running 556. I have heard that in 2013 they are dropping the current v8 in the camaros and finally dropping that beast under the hood. From the last time i checked the V had ran the fastest track time of any 4 door sedan in history. I have watched so many video on youtube of this car, it smoke beemers like it was born to >_< haha the only issue they had with the car in any test is that it has so much power going to the rear that it tends to slide out a bit in very aggressive corners vs the beemers that had the front end wash out. Its got a fantastic interior as well, theres a cut out in roof for the back seat for those not so short people to sit very comfortable, and has all the usual, like air condition/heated leather, and one mean bumped hood which is 100% mechanical and not for astetics. (the motor would not fit in that motor cavity without it) if you get a chance to go for a drive or drive one it is well worth it >_< (i am still waiting to drive it, although i really don't think it will happen)

Actually the LSA is quite a bit different from the Corvette LS9 engine. Like the LS9, the LSA is an aluminum block 6.2L V-8 with an Eaton 6th generation two-rotor supercharger. The basic configuration matches the LS9 with the blower sitting in the valley of the block. An air to liquid intercooler sits on top of the supercharger. Differences between the two engines are primarily intended to give the Cadillac an extra air of refinement compared to the sports car and result in the LSA "only" producing 550 hp and 550 lb-ft of torque. The single biggest difference leading to lower output for the Cadillac is the supercharger displacement. While the LS9 has a 2.3L blower, the unit in the CTS-V only displaces 1.9L. Aside from the size, the blower is based on the same four lobe rotor design with 160 degrees of twist to the lobes. The design provides greater efficiency and thirty-five percent less power draw than the previous three lobe design in addition to much quieter operation. The maximum boost pressure is reduced from 10.5 psi to 9.0 psi. Since the CTS-V had a little more vertical and longitudinal space under the hood than the Corvette, the engineers were able to use a different intercooler. The LS9 intercooler has two separate heat exchanger units that are split on either side of the supercharger outlet. The LSA has a single heat exchanger that is slightly taller but has more efficient airflow. The other packaging difference is the use of a third drive belt dedicated to the supercharger rather than the two belt system used on the ZR1 engine. The pistons in the LSA are hyper-eutectic cast aluminum rather than being forged. The piston skirts are polymer coated for improved scuff resistance and reduced NVH. The sumped top design of the pistons is retained, which allows for clearing the valves without machined valve pockets. The continuous surface free of edges helps to avoid hot spots that can contribute to pre-ignition.
The LSA also gets the dual pressure fuel system used in the the LS9, but the top pressure is reduced from 600kPa to 450kPa. The LSA gets the same beefed up block casting, seven-layer head gasket and 12mm head bolts as its big brother. The improved lubrication system including the squirters that spray oil on the bottom of the pistons is also retained. In total, the LSA and LS9 have about 100 new part compared to the LS7 in the current Corvette Z06. Of those, about twenty-five percent are common to both engines.

Seven layer head gasket?I think I'm falling behind the times.That caddie is a hell of a deal but I'm sure they must screw you long and hard when it comes time for repairs.I sometimes wonder if they just don't generate a report from the computer and adjust your bill accordingly.

too bad all that american power comes with american styling and build quality :p

....because imports never have any issues. like the M3's subframes that fall apart. Or the VANOS system that works so flawlessly.

Domestics for life.

Some reviewers felt the German ergonomics were slightly better.I like the style.
