As chance would have it, I was planning to drive to a baseball game in Milwaukee last month when General Motors called to send over a Chevrolet pickup that runs on gasoline and compressed natural gas (CNG). The road trip became a good opportunity to test a bifuel truck over long distances.
Equipped with a 6.0-liter V-8 engine, six-speed automatic transmission, 4:10 rear axle and four-wheel drive, the 2015 Chevrolet Silverado 2500 crew cab behaved much like a standard three-quarter-ton pickup. Rated to tow up to 13,000 lb, this truck also included a $9,500 CNG option that, according to GM, gives the truck a combined range of 650 miles.
