And Pontiac? Where do we begin? Take one look at the Pontiac lineup, and it's easy to see what's missing. Pontiac was always GM's "march to a different drummer" division with attitude to go and a lineup of hot cars that always offered something extra, something a little raucous and definitely outside of the typically staid GM solar system. As a matter of fact, Pontiac and Chevrolet frequently crossed swords over the years in a lingering dispute about just who was the performance division within GM. When Pontiac was really red hot, Chevrolet squawked - and loudly - but the intramural contentiousness was always good for GM because that was when they were building some of their most memorable performance machines. But now, Pontiac is hurting. The Vibe? It should have been a Chevrolet. It has absolutely nothing to do with the Pontiac brand image. The G6 has a shot with its expanding offerings, but it should be considered Pontiac's entry-level car. Period. The GTO at least is in the right direction philosophically for Pontiac and origins aside, it is the high-performance value in the North American market. The Solstice will be a one-off hit - if it's executed properly. But where is the kick-*** Pontiac rear-wheel-drive sedan that looks like nothing else in the GM lineup (or anything else for that matter) in terms of content, value and performance? It's MIA - and that's why the Sigma is so desperately needed for the car company formerly known as GM's "excitement" division. And one more thing, GM strategists need to get off this kick that Pontiac has to be something it isn't to succeed in this market. If Pontiac is to survive, let alone thrive, it will have to do it by being Pontiac - not some sort of weak-kneed BMW clone.
