Seattle Firm Emphases Norm-Breaking Natural Gas Vehicles

An order for highly specialized Cadillac limousines, compressed natural gas-fueled, for luxury transport in Las Vegas has helped World CNG re-define itself as a provider of custom natural gas vehicles that aren’t available anywhere else. Liquefied natural gas trucks in Washington State constitute another key example.

CNG Cadillac limousines for Las Vegas and LNG-fueled F-550 utility trucks for Washington State are among the custom, nowhere-else-to-be-found NGVs helping Seattle-based World CNG redefine itself.

World CNG secured its own U.S. EPA certification of the re-flashed fuel systems for the Cadillac XTS limousines with 3.6-liter direct injection engines for MGM Resorts International.

“We’re applying our engineering expertise and calibration clout,” says World CNG president Garret Alpers.

‘Very High-End, Very Customized’

Close to home in Seattle, World CNG has made possible a fleet of LNG trucks for the Washington State utility Potelco, including first-of-a-kind Ford F-550 vehicles fueled by LNG (F&F, March 24).

“These are two very high-end, very customized natural gas vehicle products,” Alpers told F&F.

Supported by a new stable of calibration specialists, the World CNG strategy is to offer custom NGV designs for vehicles and fueling combinations that haven’t been available.

‘All the Major OEMs’

“We’re doing it across all the major OEMs,” Alpers says.

Beyond the Cadillac ECU re-flash, World worked closely with Royale Limousine in Massachusetts (which stretched the Cadillac XTS vehicles by 70 inches; F&F, April 7) on the design of a back-of-the-driver mount for the CNG limousines’ single Type IV fuel tank. The 21-by-45-inch Hexagon Lincoln cylinder holds 15 gasoline gallon equivalents. The World CNG engine system boasts efficiency of about 20 miles per GGE, Alpers said, allowing him to express range conservatively at 260 miles per fill.

The LNG-fueled Ford F-550s feature a World CNG-certified fuel system for the vehicle’s 6.8-liter, three-valve engine (suitable too for the F-650 and -750), “developed specifically for intense commercial work fleet use in challenging operating environments,” Alpers says, with “exceptionally clean emissions for vehicle class.”

The “LNG fuel system and excellent fuel economy,” he adds, “means 800 to 1,000 miles of range per tank.”

The World LNG fuel system includes 119-gallon LNG tanks from Taylor-Wharton, custom-engineered into the Potelco service body with proprietary cradle mount, integrated fill port, and electric fuel gauge with interior readout.

The LNG systems for the Potelco trucks were installed at World CNG’s facility in Seattle.

The CNG systems for MGM’s Cadillac XTS limousines were installed at World CNG Southwest in Las Vegas.

World CNG also has an installation center in Chicago and a development center in Detroit.
