Just being discussed on GMI, there's a link to the Canadian International Auto Show that lists the 2009 Chevrolet Traverse, and has brief details:
Seemed like a possible flub, until then a senior member of GMI said this, after one person brought up that it would be awkward for the new cheapest Lambda to have this engine and not the others:2009 Chevrolet Traverse
Based on GM’s popular midsize crossover architecture, the Traverse delivers a robust and satisfying combination of power, efficiency, ride and safety. The driving experience is supported by a sophisticated, 3.6L DOHC V6 that features variable valve timing and gasoline direct-injection technology. It is designed to provide excellent power and efficiency that translates to usable, power-on-demand performance and is expected to deliver the best highway fuel economy in the segment.
So, looks pretty sure. We shall see, among the other small model year changes that should be released in March/April sometime for the entire GM line-up.All of the 2009 Lambda vehicles will have DI on the 3.6L.
