PRO ADVICE

“The Sierra 2500 goes straight to the point. You get a very effective 6.6L V8 that delivers 401 horsepower and 464 lb-ft, paired with a 10-speed automatic transmission. But if you tow heavy often or drive over long distances frequently, the 6.6L Duramax turbodiesel V8 gives you the muscle you need, with 470 horsepower and especially 975 lb-ft. It really depends on your use.”
