The least surprising cancellation is the Pontiac G6 GXP, which will not see a 2010 model year. It sported a slightly more powerful V-6 engine than the G6 GT and a six-speed automatic.
Chevy takes the hardest hit, losing a number of its SS models, with the Impala SS, HHR SS Panel and Cobalt SS sedan cut for the 2010 model year. The Cobalt SS coupe will be cut later, at the end of calendar year 2009 or early 2010.The HHR SS will continue throughout the entire 2010 model year, ending in June 2010.
Cadillac will not be taking orders for a future STS-V, meaning no 2010 model either. However, the brand says with an ever-changing industry things could change.
