The Model 348 was designed to exceed the rigid demands of Class 7 and Class 8 specialty application markets that require rugged durability and a wide range of optional content. The Model 348 represents a multi-dimensional performer with a GVW from 33,000 to 56,000 lbs. and optional capacity ratings to suit almost any vocation. The 348 is also available in a specifically designed all-wheel-drive configuration. From construction and crane service to utility and delivery services in both Class 7 and Class 8 markets, the 348 is in a class by itself.
All Peterbilt natural gas platform vehicles are equipped with the Cummins Westport HD engine, which offers a 320-horsepower rating and 1,000 lb-ft of torque and provides an extremely efficient fuel-to-power ratio. Efficient and emissions compliant, the HD natural gas engine produces horsepower and torque comparable in capability and service to the diesel engines. These efficient and emissions compliant compressed (CNG) and liquefied natural gas (LNG) power platforms join Peterbilt’s family of SmartWay-certified on-highway vehicles and alternative fuel vehicles, forming the industry’s most comprehensive environmentally responsible lineup.
The heart of Peterbilt Medium Duty
Available with either the PACCAR PX-6 or the PACCAR PX-8, the 348 has the power to get the job done. The PX-6 is an in-line, 6-cylinder design with 4 valves per cylinder and a high-pressure common rail fuel system. Delivering the best power-to-weight ratio in its class, the PX-6 offers high horsepower and torque in a dependable, long-lasting package. The PX-8 delivers 1,000 lb-ft of torque for increased throttle response and acceleration. PACCAR PX engine options give customers in traditional Class 7, Class 8, vocational or specialty applications outstanding fuel economy, greater reliability and unsurpassed performance.
The Model 348 is constructed with an all-aluminum cab that is lightweight for fuel efficiency and corrosion-resistant for durability. The Metton® hood is lightweight but strong, and tilts open a full 90 degrees for easier access to key service points. The stainless steel grille surround is long lasting, and its durable design provides superior protection of the engine cooling system.
Where Form and Function meet.
The Model 348’s technology starts as soon as the driver sits behind the wheel. The LED backlit gauges readily communicate systems status and are designed to reduce eye strain. The standard driver’s in-dash display includes virtual gauges and truck, trip and performance information in driver-selectable English, French or Spanish.
The Model 348 is available as an electric hybrid with the Eaton Hybrid Electric System. This system features a hybrid drive unit, which includes a 340-volt motor/generator, an Eaton UltraShift transmission and an automatic linear clutch actuator. When the diesel engine is combined with the Hybrid drive unit, the power is boosted to 320 hp and a torque limited 860 lb-ft of torque.
Where Form and Function Work
The ergonomic dash features LED backlit gauges that are easy to read, a driver information display for critical vehicle data and rocker switches within easy reach. Power controls for door locks and power windows are conveniently located in the door panel, and a multi-functional turnstalk and easy-to-read driver information center provide a comfortable, ergonomic driver environment. An in-mold process embeds color directly onto the dash for a long-lasting finish, virtually eliminating fading, scratching and peeling.
