The new trucks offer a slight departure from the previous CT models, based on customer feedback.

Dave Schultz, vocational truck product manager for Cat, said many owner-operators and fleets think a truck’s looks should reflect pride of ownership and reinforce a companies brand.
The CT680L features a three-piece Metton hood, three-piece chrome bumper, three-piece chrome stainless steel grill surround, composite halogen headlights and incandescent parking and turn lights.
The more subdued CT680LG sports a one piece fiberglass hood, three-piece black bumper, integrated fiberglass grille surround, sealed beam halogen headlights and LED parking and turn lights.
The CT680 base chassis, on which both the LG and L versions are built, is set forward with a 124-inch BBC, which makes it Cat’s longest truck by 10 inches. Combined with parabolic taper leaf suspension the far-forward front axle and long wheel base improve driver comfort levels especially for all day driving.
The new trucks are also available in both tractor and truck configurations, and a glider kit is expected in mid-July. A Cat CT series 13-liter vocational truck engine with dual sequential turbochargers powers the CT680.
