Chevy G4500 Specifications

by DarienC

The Chevy 4500 is a cutaway truck in Chevy's commercial truck and van line and is used primarily as an ambulance, shuttle, school bus or recreational vehicle. A cutaway truck is basically a cab, chassis and frame to which companies add their own customized module. For instance, a shuttle company would buy the Chevy 4500 and add a module full of seats to the chassis.

The "G" in the Chevy G4500

Chevy refers to the vehicle simply as the 4500 or the Express 4500 Cutaway. However, many ambulance service providers and emergency vehicle dealers refer to Chevy 4500s with ambulance module upfits as Chevy G-4500s and apply designations such as "Braun Chief XL G-4500" or "Chief XL Chevy G4500 Type III." These are vehicles with customized modules added to the standard Chevy 4500 cab, frame and chassis, and the added designations are related to the customized upfits rather than the Chevy 4500 itself.


The 2010 Chevy 4500 comes standard with a RWD Vortec 6.0L V-8 with 323 hp at 4,600 rpm and a torque of 373 lb.-ft. at 4,400 rpm. A Duramax 6.6L Turbo-Diesel V-8 engine is optional. Either engine is paired with a Hydra-Matic six-speed transmission with Tap-Up/Tap-Down driver shift control.
