GM Announces Interim Model Year Pricing for 2007 Medium-Duty Lineup

August 23, 2006

DETROIT – General Motors has announced interim model year pricing for the 2007i lineup of C-Series and T-Series medium-duty trucks (base models and select options), effective first quarter of the 2007 calendar year. The medium-duty lineup includes a broad range of the C-Series and T-Series trucks, available with either gas or diesel engines.

The diesel price increase, ranging from $2,950 MSRP to $7,600 MSRP, is necessary because of more stringent federal diesel emissions standards for 2007, resulting in additional equipment, hardware, and software.

2007i C4500 and C5500 models equipped with the optional 6.6L Duramax turbo-diesel engine receive more horsepower and torque than ’06 models; the C6500, C7500, C8500 and T-Series models equipped with the Isuzu 6H engine also feature more standard horsepower and torque.

The prices for GM medium-duty diesel models are competitive with other manufacturers, because all 2007i diesel-equipped vehicles require new or revised equipment to comply with the new federal emissions standard.

“The changes with diesel-equipped vehicles are the direct result of GM’s compliance with the new federal emissions standard,” said Mark Karney, General Motors director of marketing for commercial trucks and vans. “GM’s pricing is competitive, as all manufacturers have taken similar actions to comply with the new emissions standard.”

Along with diesels, GM offers a gasoline engine for all of its Class 6-8 conventional 6500-8500 trucks for customers with local, low-mileage operating requirements.

To comply with new emissions standards, in the first quarter of 2007, the Duramax 6.6L and Isuzu 6H engines include enhanced exhaust gas recirculation (EGR), variable-geometry turbocharging systems (VGT), closed crankcase ventilation, revised calibrations, and new diesel particulate filters (DPF). The DPF traps diesel particulate matter and turns it to ash during a regeneration process. GM medium-duty diesel engine trucks also include a patented exhaust gas cooler to reduce exhaust gas temperature during the regeneration process.

The new emission systems require ultra-low sulfur diesel fuel to reduce NOx emissions by 90 percent compared to the current standard.

The Duramax 6.6L turbo-diesel is offered with increased power and torque available for medium-duty applications. Versions are available with 300 horsepower and 520 lb.-ft. of torque, as well as a new 330 horsepower with 620 lb.-ft. of torque option. Duramax applications include both standard and vertical exhaust systems.

The Isuzu 6H diesel engine returns as a 7.8L workhorse that is offered with five horsepower and torque outputs. The base rating increases to 215 horsepower and 560 lb.-ft. of torque – a 7.5-percent increase in both horsepower and torque over 2006 models. It is the base engine in T6500 and T7500 models. The 6H engine is available with a maximum of 300 horsepower and 860 lb.-ft. of torque.

All 6H engines feature an integrated oxidation catalyst, diesel particulate filter, and GM’s patented exhaust gas cooler. Higher-output versions of the engine feature a higher-capacity DPF. The exhaust routing remains on the left side on C-Series models and the right side for T-Series; an optional driver-side, cab-mounted vertical exhaust is available on C-Series. Also, the exhaust brake option is available at a reduced price of $200 MSRP.

GM offers the Vortec 8.1L gas V-8 as an economic alternative to diesel engines, for customers with lower-mileage requirements. The Vortec 8.1L engine is rated at 325 horsepower and 450 lb.-ft. of torque or 295 horsepower and 440 lb.-ft. of torque in C6500/7500/8500 models.

The C4500/5500 with the base (gas) engine is mated to a standard Allison 1000 Series five-speed transmission, with a six-speed available.

The C6500/C7500 with the base (gas) engine comes standard with the Allison 2000 Series five-speed automatic transmission and an optional six-speed. C6500/7500 models equipped with the optional diesel engines feature a standard Allison six-speed automatic transmission.

The T6500/T7500 is powered only with an Isuzu 6H diesel engine and comes standard with an Allison 2000 Series six-speed automatic transmission.

The T8500 is powered only with an Isuzu 6H diesel engine and comes standard with an Allison 3000 Series six-speed automatic transmission.
