The new certifications, which bring the company’s total number of EPA certifications to 40, cover approximately 200 2010-2012 General Motors Chevrolet and GMC light-duty trucks and SUV platforms with 4.8L and 5.3L engines. The EPA certifications allow Icom to convert these fleet vehicles in the U.S. market for propane/autogas bi-fuel use.

The Chevrolet-brand vehicles include Silverado, Tahoe, Express vans, Avalanche, and Suburban. The GMC-brand vehicles include Sierra, Yukon, and Savana vans.

Icom’s EPA certifications now cover approximately three million vehicles, primarily Ford and GM fleet vehicles. The company soon expects to receive additional certifications for Ford, GM, and Dodge vehicles.
