Ford's new active wheel shutters in the closed (left) and open positions on the Atlas concept pickup.
Ford’s Atlas
concept pickup, unveiled Jan. 15 at the 2013 North American
International Auto Show in Detroit, provides a glimpse at some key
fuel-efficiency technologies engineers are readying for the 2015 F-150.
Besides the shift to high aluminum
content in the front end and cab, aimed at reducing the 2015 trucks’
curb weight by up to 700 lb (317 kg) versus the current F-150, and a
next-generation EcoBoost powertrain featuring auto stop-start, Ford is
putting a serious focus on reducing aerodynamic drag, said Raj Nair,
Group Vice President of Global Product Development.
The Atlas shows a few of the results of “our extensive aero development” on the next-generation pickup, Nair told AEI.
An unexpected feature on the Atlas is
active wheel shutters. The shutters are in at-rest position behind the
wheel spokes when the vehicle is stationary and at up to moderate road
speeds. As vehicle velocity increases to above 60 mph (97 km/h), its
wheel-speed sensors signal a dedicated battery that powers the shutters.
They deploy in a fan-like pattern (think of a Chinese fan being
opened), closing off the openings between the wheel spokes and thus
enabling smooth airflow across the wheels.
Active grille shutters and an
automatic-deploying active front air dam work in conjunction with the
active wheel shutters, Nair said. The Atlas concept truck also features
power running boards that tuck in close against the truck’s body at
speed, also helping reduce drag.
Ford’s simulations and early testing
indicate the aero package as shown on Atlas is capable of providing a
fuel-efficiency gain of more than 2 mpg (0.85 km/L) at highway speeds
without diminishing towing or hauling capability. Full-line automakers
Ford will have to improve their light-duty trucks’ fuel economy to
approximately 32 mpg to comply with the new U.S. CAFE regulations that
require a 54.5-mpg fleet average by 2025.
The 2015 F-150 also is expected to
feature a 10-speed planetary automatic transmission, currently under
development, according to Ford and supplier engineering sources. As
previously reported by AEI, Ford and General Motors
are in discussions on sharing advanced transmission technology as they
have done with the highly-successful six-speed transaxle program.
Other technologies revealed on Atlas
that have potential for the 2015 production truck include a 360°
point-of-view camera that provides the driver a “bird’s-eye” view of the
vehicle; driver-controlled trailer-backup assist; dynamic trailer-hitch
assist that helps line up the hitch with the trailer coupler; a
dual-purpose tailgate step/cargo cradle; and LED headlamps and
taillamps.
