Diesel-powered versions of the Chevrolet Silverado and GMC Sierra Run may run out due to a gap in production. GM is set to halt producing the current version of the Duramax in mid-December and it will be about four months before a re-engineered 2010 Duramax will begin to be built in late April, says Autonews.
GM's pickup inventory lean is already lean but since analysts predict that sales will soon pick up, it becomes more likely that supplies will be depleted.
During the 4-month gap, GM will retool the Moraine, Ohio, plant where the engine is built, and GM engineers will tune the 6.6-liter turbocharged diesel V-8 to meet tough new emissions rules that take effect Jan. 1.
GM revised the engine and added a system to inject urea into the exhaust periodically. The result is that the chemical reduces oxides of nitrogen or NOx.
Drivers will be prompted to refill the urea tank through low-fluid alerts. Scott Brasher, general manager of Brasher Motor Co. in Weimar, Texas, said that it just received a notice that the Duramax regular cab is no longer available for orders.
Brasher's last order for extended-cab diesels is expected to come in next month. To pad his inventory, he has been purchasing diesel trucks from other dealers.
