ATLANTA (July 19, 2016) – Gray Line Worldwide, the world’s largest provider of sightseeing tours, selects cleantech innovator NG1 Technologies as an Allied Partner to bring TechFlo Exhaust, NG1’s aftermarket exhaust system, to Gray Line licensees. As an Allied Partner, NG1 joins a select group of brands whose products and services are available to Gray Line licensees, providing these companies with access to the advanced fuel savings of NG1 TechFlo Exhaust.  Gray Line Worldwide’s Allied Partners include several established and respected transportation industry companies, such as ABC Companies-Van Hool, Bridgestone, Detroit Diesel, Motor Coach Industries and Prevost.

Gray Line Worldwide selects companies to be Allied Partners that offer products which add value to local Gray Line licensees’ delivery of experiences. NG1 Technologies’ business development team, Art Meissner and Chic Childs, developed the partnership with Gray Line Worldwide’s Vice President of Strategic Programs, Dale Berridge, based on shared family-like business values and respect. The companies have developed joint short and long term marketing plans, aiming to build a lasting business relationship.

Through the partnership, NG1 TechFlo Exhaust will be introduced to key decision makers from a broad range of companies. Gray Line licensees are currently installing NG1TechFlo Exhaust systems at select locations across the U.S., with plans to roll out the product to all U.S. locations in the coming months and eventually international sites.

“Gray Line Worldwide seeks companies with the newest technologies to better strengthen the company as an operator, and we are thrilled to be selected as an Allied Partner,” says NG1 Technologies CEO Cynthia O’Donnell. “Preliminary results on both motor coaches and school buses are very promising, and we look forward to providing Gray Line licensees with the opportunity to increase fuel efficiency and improve their bottom line by utilizing our exhaust system.”

The system provides an average of 10 percent fuel savings, while also improving torque and horsepower and lowering emissions and sound pollution.
