Finally GM has released it's next generation Northstar variable valve drivetrain with the cool new constant shift transmission and electric overdrive for efficient highway cruising. For someone like me that wants the low end torque for off road and towing there has only been one option (Truck = Low Mileage). Thanks to Cadillac for the option now available so that the engine will "switch off" SIX of the cylinders and add the electric assist at highway speed to get astounding efficiency while cruising. The around town numbers are not nearly as impressive, but an acceptable 19 MPG. This new luxury, cutting edge truck from GM's flagship is the perfect option for those of us who want to have our "Cake" and eat it too... April fool's day cake that is.
