Oshawa, ON — Dec. 26, 2001 — The Chevrolet Silverado and GMC Sierra are the industry’s first full-size pickup trucks which will be available with the option to operate on ethanol (E85) fuel, General Motors has announced.

E85, a renewable fuel made from starch crops such as corn, helps reduce air pollution. In addition, E85 vehicles meet mandates for alternative fuel-powered vehicles.

The E85 Silverado and Sierra are suitable for moving cargo and crew on rough terrain, in adverse road conditions and up severe inclines. The E85-compatible models are additions to GM’s entire E85 compatible truck line-up. GM also offers the Chevrolet S-10 and GMC Sonoma compact pickups, and Chevrolet Tahoe and Suburban and GMC Yukon and Yukon XL sport-utility vehicles with E85 compatibility.

The E85 compatibility feature will be offered as a special equipment option on select 1500 series Chevrolet Silverados and GMC Sierras equipped with the 5300 Vortec engine. Vehicle production is expected to begin in early 2002.

Small industrial engine announced

In another announcement, General Motors has made available a 1.6-litre, single overhead cam, inline four-cylinder engine for the industrial market. Called the Vortec 1600, it widens GM’s industrial engine range from 1.6-litres to 8.1-litres.

Design features of the Vortec 1600 include a 79 mm bore by 81.5 mm stroke, 9.4:1 compression ratio and cast aluminum cylinder head with valve seat inserts. An iron block is used. The Vortec 1600 also features a distributorless ignition system which reduces maintenance and increases reliability.

The Vortec 1600 will be adaptable for use with gasoline, liquid propane (LP) or compressed natural gas (CNG). Each fuel type has different applications. Gasoline is good for higher output mobile equipment. Liquid propane versions will be preferred by indoor material handling vehicles. CNG is a favourite of gen set manufacturers.
