Chevrolet confirmed today that it will reveal its new Class 4 and 5 Silverado chassis cab trucks at The Work Truck Show in March.

Powered by the venerable Duramax hooked to an Allison transmission, Chevy's new heavy pair are set to be available in regular and crew cab models, with both two and four-wheel-drive capability on offer. Additionally, the brand is promising an expansive suite of industry-leading connectivity features like 4G LTE Wi-Fi and telematics offerings which will be a boon to fleet managers across the country. 

"The Silverado 4500HD/5500HD trucks are the flagship of our full-line commercial truck portfolio and we've designed them to be among the best in the industry in maneuverability, serviceability, visibility, quietness and comfort, diesel fuel economy and more," said Ed Peper, U.S. vice president, General Motors Fleet.

"At GM Fleet, we are determined to deliver on our three pillars: Great Products, Innovative Business Solutions and an Exceptional Customer Experience, and I'm confident that with these new trucks, we'll exceed the expectations of not only our fleet customers, but the drivers and upfitters as well."

Additional technical specifications for the new Silverado 4500HD/5500HD will be released at the reveal in March. The trucks are expected to begin production in late 2018, making early 2019 deliveries most likely.
