I work for a supplier to GM. I got a chance to test drive the LGX(3.6L) and LGW(3.0 Twin Turbo) and both vehicles were bad ass. The vehicles I tested both had active T-Cases on them, so at launch torque is ported to the front wheels instead of just frying the rear tires. I was thoroughly impressed with both engines. The 3.0L twin turbo, was my favorite among the two because it had more power. It makes a little over 400hp. Hopefully this motor will find its way into other affordable vehicles. The cost of the Cadillac is around $90k to $100k.
