Peterbilt has updated the Model 220 cabover with new design features and options that result in weight savings, better performance, and improved serviceability, according to the company.

New features include a redesigned vertical exhaust and lighter-weight battery box that's more corrosion resistant, said Peterbilt, which made the announcement at the NTEA's Work Truck Show in Indianapolis.

The new vertical exhaust is a single-canister aftertreatment design that replaces the former dual-canister design. The new exhaust reduces weight by up to 100 pounds per unit and increases the Model 220’s cab-to-axle distance by 6 inches. The battery box in this exhaust configuration has also been reduced in size, resulting in a combined weight savings of up to 165 pounds.

The standard battery box cover on the Model 220 has also been improved and is now made from a  lighter-weight aluminum instead of steel. The aluminum battery cover has better corrosion resistance and improved aesthetics.

The company also announced a new frame layout on the Model 220 that features better clearance for PTO installation through the left-hand rail. This design tweak allows for faster and easier PTO mounting and serviceability. The new design is standard on Model 220s ordered after January. 

The 2017 enhancements are available for immediate order. Peterbilt launched the Model 220 in 2014. It's available for multiple applications including urban pick-up-and delivery, refuse, landscaping, street sweeping, and striping.
