Nat G CNG Solutions Delivers First Bi-Fuel GM Pickups with 5.3L DI Engine

On Wednesday, Nat G CNG Solutions announced that it has delivered the first natural gas half-ton pickup trucks with GM’s 5.3L direct injection engine. The 2015 GMC Sierra and Chevy Silverado trucks were purchased by local Houston company NewTex Plumbing and San Antonio-based Pioneer Energy Services. The trucks feature the new DuraDrive DI natural gas system supplied by Utah-based AGA Systems. During EPA testing, the DuraDrive DI set a record for efficiency on an eight-cylinder natural gas truck, achieving 23 miles per gallon highway. The half-ton CNG upgrade from Nat G comes standard with a 24 GGE cylinder. Nat G has pre-orders for more than 50 units of the DuraDrive DI, which will be delivered to customers in Texas and Louisiana before the end of the year. “Customers have been looking forward to getting a high-quality natural gas option for the new direct injection engines from General Motors,” said Bob Lukefahr, co-CEO of Nat G. In addition to the 5.3L engine, AGA Systems has also started shipping the DuraDrive DI for GM’s 6.2L direct injection engines, which are used in the Chevy Suburban, GMC Yukon XL and several larger pickup trucks. Nat G is offering an underbody cylinder system for the full line of GM full-sized SUVs.
