GM Unveils Sixth-Generation V-8 Engines for 2027 Trucks Amid Recall Scrutiny
General Motors has introduced its sixth-generation small-block V-8 engines, designed for the 2027 Chevrolet Silverado and GMC Sierra. The new L76 5.7-liter and L78 6.6-liter units offer increased power and efficiency, with the larger engine producing 481 horsepower. GM emphasizes advanced quality controls and a new architecture to address concerns following recent engine recalls. Production begins at the Flint, Michigan plant, with expansion planned for facilities in New York and Canada. This move signals a renewed focus on internal combustion engines for full-size pickups, despite ongoing investigations into previous engine failures.
