Frequently Asked Questions about Natural Gas

Thanks to natural gas engine technology you can lower fuel costs, improve fuel economy, and lower incremental maintenance costs—all while doing the right thing for the environment.

 

How does natural gas compare to diesel?

CNG LNG

Available in compressed natural gas (CNG) or liquefied natural gas (LNG), with near-zero emissions, natural gas engines are not only quieter than their diesel counterparts, they’re also decidedly cleaner. Switching to natural gas translates to potentially significant fuel cost savings: As the price of diesel continues to rise, the cost of natural gas remains relatively lower and stable. Federal and state vehicle tax credits—as well as infrastructure tax credits available to green fleets—can greatly reduce acquisition costs.

Is natural gas better for the environment?

By implementing Freightliner’s natural gas-powered products, you’re doing your part to help the environment. The Cummins Westport ISL G engine, for example, isn’t just one of the most dependable and economical engines on the road today, it also reduces greenhouse gas emissions (GHG) up to 20%. By investing in a natural gas-powered Freightliner vehicle, you’re greening-up your bottom line and the environment.

What kind of engines are used by natural gas vehicles?

Cummins Natural Gas Engine

Freightliner’s natural gas vehicles, including the Business Class® M2 112 and 114SD, are powered by the Cummins Westport ISL G 8.9 liter engine. Offering horsepower ratings of 260, 300 and 320 and torque ratings of 660, 860 and 1000 lb ft, the spark-ignited ISL G is the only factory-built, dedicated natural gas engine available in the commercial vehicle market. It’s built on the same assembly line as ISL diesels. The ISL G offers advantages including a maintenance-free aftertreatment system with a three-way passive catalyst, reducing complexity.

The Cummins Westport ISX12 G offered in the Cascadia 113 features horsepower and torque ratings of 400 hp/1450 lb ft and utilizes the same stoichiometric cooled EGR combustion technology with spark ignition as the ISL G.

What kinds of transmissions are used by natural gas vehicles?

The M2 112 and 114SD natural gas vehicles feature the 3000 series HS and RDS Allison automatic transmissions. The ideal transmission for alternative fuel vehicles, Allison transmissions include patented torque converter technology that results in improved startability at the launch of the vehicle, full power shifts, and better performance. The Cascadia features the Allison 4000 HS automatic, or an Eaton manual transmission.

Methane Detection System

Is natural gas safe?

The Freightliner M2 112 and 114SD natural gas trucks offer the standard product advantages of superior maneuverability and visibility. But they also are the only natural gas-powered trucks and tractors with OEM factory-installed and warranty-covered natural gas fuel tanks and components, including a standard methane detection system.

The CNG tanks Freightliner installs at the factory are Type IV plastic composite tanks wrapped in carbon fiber and feature an expected life span of 20 years, while the LNG tanks are constructed of stainless steel. The CNG and LNG tanks featured on Freightliner products are engineered to meet or exceed all applicable safety standards. In the rare occurrence of a CNG tank puncture, the fuel will simply vent into the atmosphere, rather than pool on the ground.

Are Freightliner’s natural gas Trucks drive-ready?

Bottom line: Freightliner Trucks offer the only turn-key, natural gas conventional truck solution in the industry. These versatile, hardworking trucks and tractors are perfect for regional haul and vocational applications including construction, refuse, food and beverage, pickup and delivery, utility and municipal applications.

The M2 112 and 114SD natural gas products can handle GVWs up to 66,000 lbs, but can be spec’d to handle GVW/GCW up to 80,000 lbs depending on application from Freightliner, Cummins, and Allison. The Cascadia 113 Day Cab with natural gas is a true Class 8 vehicle that can handle your regional haul and LTL needs.

Is natural gas cheaper than diesel?

Switching to natural gas can lead to significant fuel cost savings. As the cost of diesel continues to rise, lower cost natural gas prices remain relatively stable, making natural gas an economical choice to meet your short-haul and vocational needs.
