Chevrolet has just updated its commercial fleet specs including Silverado and Express.
Chevrolet has announced a new engine for the Express and Low Cab Forward trucks, as well as a host of improvements for the Silverado 4500 HD, 5500 HD and 6500 HD chassis cabs. Express will have 24% more torque and Silverado has a 23 percent higher gross combined weight rating.
“Our commercial fleet sales growth is a result of excellent product and an even better team,” said Ed Peper, U.S. vice president, GM Fleet. “The changes for Express, Low Cab Forward and medium-duty trucks are great examples of the team’s commitment to helping customers with their fleet vehicle needs. With the product changes for 2020, we are on track for another year of strong commercial growth.”
A new 6.6L V-8 gas engine for 2021 in the Express configurations and Low Cab Forward is the big news. The engine option arrives this summer. The engine is the same basic package now offered on the 2020 Silverado 2500 HD and 3500 HD. The 6.6 direct-injected engine generates 401 horsepower and 464 lb-ft of torque for the Express. That’s a healthy 17 percent more horsepower and an impressive 24 percent more peak torque than the outgoing 6.0L. The 6.6L output available in the Low Cab Forward is rated at 350 horsepower and 425 lb-ft of torque, which is nearly 18 percent more horsepower and 14 percent more peak torque than its outgoing 6.0L. Demand has been robust for the up-powered V8 Express with about 70 percent of current Express owners opted for the 6.0L V-8 option.
Chevy offered this list of updates to the Silverado 4500 HD, 5500 HD and 6500 HD chassis cab trucks:
