Why did the LS4 have to go away? I was wondering why the 2009 Chevy Impala SS was the last year for the LS4.
The Impala soldiers on pretty much unchanged into 2011 until it gets redone. Did the market not justify it's existence? Did the downturn in the economy coupled with a sour taste for ANY GM product lead to its demise?
If you think about it, a 303 HP V8 is not really that competitive when you see V6's with 312 and up as commonplace and I'm not even including the VQ's that are in Nissans and Infintis. One thing the V6 engines do lack is torque and that's what gets it done at the end of the day.

It lasted a year less than the LS1 right? '97-'02 and '05-'09. The death of the Grand Prix and the birth of the G8 didn't help nor did the woes of GM. It was also a niche interest engine, how many people actually know it exists?

actually the government didn't kill it specifically, it just didn't allow it in passenger cars anymore due to it's fuel consumption. The engine is still alive in the G.M. pickup truck models.
I think one of the truck engines is LSx derived but not an official LSx monikered engine. Trending Topics

Silverado and Sierras all get iron block/aluminum head 5.3s.
Two wheel-drive Tahoes and Yukons get all aluminum 5.3s.
Four wheel-drive Tahoes and Yukons get the iron block/aluminum head combo.

Cruising at 80 from NorCal to SoCal I got 26 mpg. I got 27 mpg cruise set at 73. Peddling it myself between 62-69 depending on the slope of the road I got 29 mpg.
