Volvo Adds 'Crawler Gears' as Option on 2017 I-Shift

摘要

Volvo Trucks' 2017-model power train products include "crawler gear" options to its I-Shift automated manual transmission that are aimed directly at the vocational market. Crawler gears add one or two low-low ratios to aid starting on upgrades for heavy combination vehicles and vocational trucks, making the 12-speed transmission into 13- or 14-speed gearboxes, said Wade Long, product marketing director. The 13's crawler ratio is 17.54:1 and the 14's are 19.38:1 and 32:1.
