Volvo Trucks North America is rolling out a bevy on new enhancements for the 2017 versions of its D11 and D13 engines, along with a new "crawler gear" package for its I-Shift automated manual transmission (AMT) and a new "one box" exhaust emission aftertreatment system. The OEM showed off those new offerings at its Hagerstown MD powertrain factory, highlighting how its production processes are being tweaked to incorporate those new offerings.
