The Chevrolet Silverado and GMC Sierra got off to a slow start but General Motors is hoping to fix things with a series of updates.

Speaking at a recent press event, GM's executive chief engineer of global full-size and midsize trucks said the Silverado and Sierra will be updated for the 2015 model year and we can expect even more changes in the future.

Jeff Luke declined to go into specifics but hinted the upgrades will likely include styling changes, improved transmissions and updated technology. As he explained, “You’ll see some neat updates on the trucks and [full-size] SUVs, you’ll see them coming, I’d say in short order."

While Luke was coy on details, he did confirm the company is considering engine start/stop systems for their full-size trucks and SUVs. This change would help to improve fuel efficiency which is becoming increasingly important to truck buyers.
