Specifications for the 2006 Chevrolet Kodiak C4500 include four-wheel drive, a Vortec 8.1-liter V-8 gasoline engine or a Duramax 6.6-liter V-8 turbo diesel engine, and an Allison 1000 automatic transmission. The 2006 model year is part of the third generation of Kodiak vehicles.
Chevrolet manufactured third-generation Kodiak C4500 trucks from 2003 until 2009 in its Flint, Michigan, assembly plant. These vehicles feature a more spacious cab than those of previous generations and include factory-installed, four-wheel starting in 2005. The Vortec 8.1-liter has 325 horsepower, and the Duramax 6.6-liter engine has 300 horsepower. The trucks have solid front axles rather than independent front suspensions. Buyers can use these vehicles in the forestry, construction, snow plowing, agriculture and utility work industries, among others.
Chevrolet introduced a special Kodiak C4500 at the 2006 Chicago Auto Show that included premium audio and navigation systems. Chevrolet intended the truck to compete with the market for the International RTX. The C4500 had higher horsepower, but the RTX had higher towing capacity. The base price of the vehicle was $70,000.
The Presidential State Car of the United States, commonly called Cadillac One, is built on the Chevrolet Kodiak C4500 chassis and powertrain. The 2009 armored vehicle is the first presidential limousine that is not entirely based on a production vehicle. It also includes parts from the Cadillac Escalade and STX.
