Detroit, Michigan – General Motors has announced that the 2011 GMC Sierra heavy-duty pickups have increased towing and payload ratings, making them the most capable and powerful heavy-duty pickups in the segment. The ratings have been increased to 21,700 lbs (9,842 kg) of towing and 6,635 lbs (3,009 kg) of payload.
“When developing the Sierra HD, our focus has consistently been to deliver customers the most capable heavy-duty trucks in the market, along with premium features and styling that distinguish GMC amongst the competition,” said Rick Spina, GM full-size global truck vehicle line executive. “Our first set of capability tests confirmed that the team had exceeded the payload and towing targets by a significant margin. Ongoing testing demonstrated a clear opportunity to increase the true capabilities of these trucks.”
For the first time ever, GMC will offer the exclusive Denali line in heavy-duty pickups with the Sierra Denali 2500 and 3500 HDs. The Denali version includes a four-bar chrome grille, body-colour bumpers, chrome door handles and accents, and 17-, 18- or 20-inch polished forged aluminum wheels.
Production of the Sierra HD begins next week in Flint, Michigan.
