We've established the ZR1 can accelerate and decelerate, but to ignore its handling capabilities is to miss where the ZR1 excels. The ZR1 pulls more than 1g on the skidpad, and by the time the massive tires do break free, rear first of course, the ZR1's controls have already offered ample tactile warnings that the end of the road is near. Also, GM/Delphi's Magnetic Selective Ride Control is standard. It's an ingenious device that uses shocks filled with metallicized fluid, whose viscosity can be altered by adding or subtracting an electrical charge. That means the dampers can be adjusted on the fly, within milliseconds of the car's bank of sensors sussing out road conditions, g-forces and whatever the driver had for dinner over last year's holidays. The ZR1 isn't the only GM car that gets this system, but it's tuned specifically for the ZR1. To one's backside, it means a startlingly supple ride quality that makes the ZR1 the best long-trip supercar ever built.
