Peterbilt Package Saves Fuel

Peterbilt Model 579 EPIQ

Peterbilt’s new EPIQ package for the Model 579 provides an optimized combination of technologies and components that can improve fuel efficiency dramatically. Announced during the Mid-America Trucking Show, the EPIQ package can improve the 579’s fuel efficiency by up to 10%, the company says. It uses an enhanced drivetrain – including Peterbilt’s new combination of the PACCAR MX-13 engine and Fuller Advantage UltraShift transmission – all available aerodynamic options, and optimized spec’ing across the board.

The EPIQ tractor includes the complete aerodynamic package, with all the fairings and aerodynamically enhanced components available for the 579. The fairings include 18-in. sleeper side extenders with 8-in. rubber flares; full chassis fairings with rubber skirts from the quarter fender to the front of the tandem axle with rubber closeouts under the sides of the cab and sleeper; and roof fairings with an exclusive rear wall closeout.

The single horizontal exhaust further increases aerodynamic performance, the other EPIQ option being a single right-hand back-of-sleeper exhaust configuration.

Other features include SmarTire Tire Pressure Monitoring System, which monitors the pressure and temperature of each tire and will warn the operator of tire-related problems. Low-rolling-resistance tires are also part of the mix

Peterbilt and its dealer network use a proprietary spec’ing software system to optimize vehicle performance, and it’s been enhanced to complement the Model 579 EPIQ by recommending the most fuel-efficient rear axle ratios and engine settings, among other options.

As well, Peterbilt now offers compressed natural gas configurations for its two newest vehicles – the on-highway Model 579 and the vocational Model 567. Both will be available with the Cummins Westport ISX12 G motor, Peterbilt announced at the show.

The Model 579 exhibited there was equipped with Quantum Fuel Systems Technologies’ back-of-cab CNG storage system. It uses Quantum’s compact Q-lite tank technology and can store 123 DGE (diesel gallon equivalents) of fuel and is designed for easy “drop-and-go” installation. The back-of-cab system can also be installed with Quantum’s single or dual frame-rail-mounted systems to reach 170 or 216 DGE combined.

Both vehicles comply with all EPA 2013 and CARB emissions regulations and will be available with several ratings from 320 to 400 hp, 1150 to 1450 lb ft of torque.

CNG configurations of the Models 579 and 567 will be in production later this year.

At Mid-America Peterbilt also introduced an all-new Model 220 to its medium-duty COE lineup. It will be equipped with a new electronic braking system (EBS) that provides quicker response and an improved braking feel, the company says.

The all-new cab features a completely redesigned interior that was engineered to improve productivity and driver comfort. The new curved dashboard features easy-to-read instrumentation and an interactive, 5-in. color display module that provides information on vehicle and driver performance.

The Driver Information Center display in the Model 220 (also available in other trucks) keeps operators abreast of all vital vehicle and engine functions. It also features advice for the driver on ways to improve in areas like increasing fuel efficiency and reducing brake wear by modifying driving behavior.
