LOUISVILLE, Ky. — Peterbilt added to its traditional truck lineup at the Mid-America Trucking Show, with the introduction of the Models 389 and 388. The new trucks feature improved aerodynamics, styling, durability, serviceability and forward lighting, the company said.
“Improving fuel efficiency is also a concern for customers of our traditional truck models and the new Model 389 and 388 can help them achieve more miles per gallon,” said Peterbilt general manager, Dan Sobic.
The new trucks feature all-new durable, yet lightweight, aluminum hoods, chief engineer, Landon Sproull told reporters at the Mid-America Trucking Show. The hoods open to a full 90-degree position and feature a new proprietary anti-blow-down locking mechanism to prevent them from being closed by wind or accidental contact.
The chassis of the 389 and 388 have been simplified to improve access to service points, Sproull said. The new tractors also feature a new lighter-weight cooling system that boasts the increased cooling capacity required to cool higher horsepower engines.
The new traditional trucks also feature new high-grade aluminum headlamps with complex-reflector technology the company says increases forward lighting by 226 per cent. Bulb life has also been extended by 600 per cent, Sproull said. A durable, impact-resistant lens cover protects the new lighting assembly from damage.
The mirrors have been retooled to improve airflow, with the enhancements reducing drag by up to 40 per cent over the previous design, Sproull announced.
“The design and styling of the Model 389 and 388 achieve both form and function,” he added. “The results are improved aerodynamics and fuel efficiency, as well as enhancements to overall performance and durability.”
Both models can be spec’d with a new Fuel Efficiency Package which can further reduce fuel consumption. The package includes a new contoured roof fairing, an oval-shaped cab-mounted exhaust, aerodynamic air cleaners, streamlined tool and battery boxes and contoured bumper and underbody fairings.
Sobic said the long-length Model 389 will be preferred by owner/operators and image-conscience fleets while the shorter BBC Model 388 will be the truck of choice among fleets and O/Os in length-sensitive operations. Both tractors will be available in early 2007.
