All-new Volvo VNL - Aerodynamic Features

A. Wedge-shaped body

The VNL’s body spreads out from the narrow nose to the A-pillar of the frame, which is slightly inset. The cab then widens to the B-pillar. This unique wedge form helps air travel effortlessly along the body of the vehicle. 

B. Hood

Curvature at the front of the hood has been increased. The hood shape reduces turbulence as air begins to move over the vehicle and eventually back to the trailer. 

C. Cooling package

The cooling package has been designed to efficiently work with the more aerodynamic hood. The hood cowl is now virtually shrink-wrapped around the engine. The recirculation shield forces air through the radiator, not around it, for superior cooling. 

D. Wrap-around windshield

The windshield is raked and curved. At the A-pillars, the glass is bonded directly to the cab’s steel body and capped at the edge for a seamless transition to the door.

E. Mirrors

The door and hood mirrors* feature an all-new shape and reduced surface area. The door mirrors are designed with a single arm to decrease wind resistance and airflow disruption around the A-pillar and door surfaces.

F. Camera Monitoring System

The soon-to-be-available Camera Monitoring System (CMS) replaces traditional door mirrors. The CMS features rear view monitors inside the cab, mounted to the A-pillar. By removing the traditional hood and large door mirrors, the CMS offers improved fuel efficiency.

G. Roofline

The angular roof features an optimized centerline. The new design eliminates an exterior sun visor, while clearance lamps are now flush-mounted to optimize air flow over the cab.

H. Roof extension

The angled roofline is further optimized by the “ski-jump” style roof extender that helps air stay attached as it travels over the cab and on to the top of the trailer.

I. Side deflectors and aero extender

The cab side air deflectors and aero extender are designed to guide airflow to the trailer. The upper and lower deflectors are affixed to the cab. The durable and flexible aero extender is longer than ever. The improved extender can also fold out for better access to the back of cab.
