Slow and steady wins the race

Cadillac's approach to cutting weight out of its vehicles reminds me of the diet plan, Weight Watchers, which advocates a slow and methodical approach to weight loss unlike some other plans that look for bigger, more immediate results. I think Cadillac's commitment to cutting mass in the ATS by reexamining every facet of the design, down to the fastener level, can't help but be the more effective way to ensure a lighter, yet still highly stable and high performance vehicle. Chuck, obviously new material choices and close attention to customer requirements played key roles in its redesign effort, but what about use of CAE software? I'm assuming that FEA played a key role in the weight reduction redesign operation.
