As well as the vocational SD model introduced a couple of weeks ago, Freightliner has also shown a new on-highway version of the glitzy Coronado. Its main claims to fame are enhanced aerodynamics, as well as some of the same mechanical and other updates seen on the SD.
 
Wind-tunnel development did things like smooth out the chrome-plated hood handle to enhance airflow over the truck. That sort of thing may sound small but it can make a significant difference. Further enhancing aerodynamics, the curved shape of the Coronado’s two-piece windshield is sloped for better air flow around and over the cab, decreasing wind resistance and lowering fuel consumption.

Freightliner says every element on the Coronado — from the hood to the fender and even the mirrors — was tested in the wind tunnel.

The truck’s updated design includes new headlights made from a strong composite material with a single reflector. And, no small deal, the headlight uses just a single bulb readily available at any auto parts store for replacement without any special tools. 

The truck’s hood tilts almost 90 degrees for easy engine access and daily fluid checks, and a special spring helps open and close the hood, reducing lift effort to 40 pounds.

Noise abatement materials include noise panels in the floor, front wall, sides and back panel to keep the truck as quiet as possible. Double-sealed doors and well-sealed windows further reduce noise.

Inside you see an updated dashboard, formed as a single piece to minimize fasteners and rubbing points that create rattles. The dashboard’s controls, valves and air switches are front-loaded and located within easy reach, says Freightliner, and all switches are backlit by LED lights for non-glare
night-time viewing.

The truck is available with Detroit Diesel DD13, DD15, DD16 and Cummins ISX engines.
