Pontiac, Michigan – General Motors announced that the 2003 Chevrolet TrailBlazer EXT and GMC Envoy XL extended length SUVs will be available with an optional all-aluminum Vortec 5.3 litre V8 engine, GM’s first Vortec V8 truck engine featuring an aluminum block. The standard engine in both vehicles is a 270 horsepower 4.2 litre inline six cylinder engine.

The new Vortec 5300 V8 will offer more than 280 horsepower and more than 320 lb-ft of torque (official ratings will be released later). It will be mated to the proven Hydra-Matic 4L60-E four-speed automatic transmission.

The Vortec 4200 inline six-powered models will be available for sale this spring and the optional Vortec 5300 V8 will be available this fall.

“By offering the Vortec 5300, we’re providing a V8 engine that will deliver outstanding performance, especially for those customers who require more towing and hauling capability,” said Chris Meagher, GM Powertrain assistant chief engineer for Vortec V8 engines. “The aluminum block reduces mass and has great thermal characteristics, giving customers improved performance and fuel efficiency.”
