Natural gas options expanded for Peterbilt models

Peterbilt expands natural gas options for Class 8, vocational vehicles

Peterbilt Motors Co., in its 75th year, announced new powertrain options for several of its natural gas vehicles that provides customers with an automated transmission and 100% natural gas engine that can be powered by either compressed natural gas (CNG) or liquid natural gas (LNG).

The Eaton UltraShift PLUS and Cummins Westport ISX12 G are available for Peterbilt Models 579, 567, 384 and 365.

This news follows the company’s announcement at the Mid-America Trucking Show, where Peterbilt announced natural gas configurations for the on-highway Model 579 and the vocational Model 567.

“North America is trailing the world in CNG technology. There’s a $1.50 difference between CNG and diesel,” said Peterbilt Market Segment Manager of Vocational Product Charles Cook. Explaining Peterbilt’s stand on natural gas, Cook said that Peterbilt has a 40% share of the natural gas vehicle market. Last year, the company sold around 1,500 trucks, he noted.

The Eaton UltraShift PLUS is available in the 13-speed MHP and 10-speed LAS series and the 11.9 Cummins Westport ISX12 G is available up to 400 HP and 1,450 lb.-ft. of torque.

According to the company, the automated transmission features intelligent shift selection software that optimizes performance and efficiency, as well as tailored shift logic that enhances braking performance.

Making this option available for the Model 579 and the Model 567 allows Peterbilt to better serve new markets with natural gas options.

Jeff Dillon of Dillon Transport, a bulk liquid and dry carrier, made the case for CNG saying that he felt “out of control with diesel prices” and that by making the switch to CNG, he has seen a $2 savings when compared to diesel.

Two suggestions Dillon offers to those considering the switch is to find a good fuel partner and a good shipper.

Peterbilt showcased a CNG version of its Model 579 at its 2014 Commitment to Class event in Denton, Texas where the company is headquartered. The vehicle, which can be seen below, was equipped with Quantum Fuel Systems Technologies back-of-cab storage system. The Model 579 was also equipped with Cummins Westport ISX12 G engine and the Eaton 10-speed transmission.
