Leading auto consulting firms are lowering their forecasts for U.S. auto sales in 2011. 

But it is unlikely to send automakers into a panic.

Some observers say the lower volume of sales means the U.S. is ripe for an incentives war among car companies.  

But Anthony Pratt with the auto consulting group R. L. Polk doesn’t see it happening.   He says a lot of the triggers that set off incentives wars in the past are missing. 

For one thing, U.S. car companies are making money at the lower volume of sales.
