At the Mid-America show Peterbilt launched a new set-forward front axle configuration for its flagship vocational Model 567, calling it ideal for mixer and other weight-conscious applications.
The Model 567 SFFA (set-forward front axle) is said to be a low-weight leader that will let customers take full advantage of that through optimized weight distribution.
It’s available in both 115- and 121-in. BBC lengths. The former has a bumper-to-front-axle distance of 29 in. and the longer model’s equivalent dimension is 31 in.
Both configurations of the Model 567 are standard with the PACCAR MX-13 engine with up to 500 hp and 1850 lb ft of torque. Both are available as a day cab or with Peterbilt’s complete lineup of detachable sleepers.
The Model 567 SFFA is available for order now through Peterbilt dealerships. Production is scheduled for June.
For weight-conscious short- and regional-haul operations, Peterbilt is also introducing a new 58-in. sleeper for its Model 579 in both low- and mid-roof configurations.
The new sleeper, which won’t go into production until the fourth quarter, reduces weight by up to 100 lb (versus the 80-in. sleeper) while including all the amenities found on Peterbilt’s larger sleepers.
The new sleeper includes a full-length door to help facilitate loading personal gear and belongings from outside the truck. Additionally, full-length, integrated extenders to minimize trailer gap and improve aerodynamic efficiency.
Other features include a full-length mattress, “abundant” storage, a television mount, refrigerator, and microwave shelf.
Anticipating and responding to changes in terrain – such as accelerating ahead of hills and coasting on the decline – Peterbilt’s new predictive cruise technology automatically optimizes engine and transmission operation when in cruise control for maximum fuel economy. It includes a neutral coasting feature that uses the truck’s momentum to save fuel and engages the engine brake to manage downhill speeds. The gain in fuel economy is said to be as much as 3%.
Predictive cruise and neutral coast work together in five steps to maximize the truck’s kinetic energy:
1. When approaching a hill, the system uses onboard maps and GPS data to accelerate to the optimal speed and adjust for the increasing road grade;
2. Before the peak of the incline, the vehicle curbs its speed before proceeding downhill;
3. Neutral coast engages as the truck rolls downhill;
4. If necessary, the engine brake engages to avoid over speeding; and
5. Cruising speed is maintained as the vehicle continues onto level terrain.
Predictive cruise also integrates with Peterbilt’s Driver Performance Assistant, which coaches drivers with fuel-saving tips.
It’s available factory installed for both the Model 579 and 567 and plans are to expand to other products in the near future.
