The GMC Sierra 3500HD is a heavy-duty truck featured in Need for Speed: The Grand Finale.
Oddly enough, the GMC Sierra and Chevrolet Silverado are the same truck - but the Sierra was chosen. If this were a Chevy, it would be the Chevrolet Silverado GMT900 Heavy Duty. As well, several of these, called "Milverados", have been purchased for Canadian Forces Use. But with 353 horsepower in the engine, the Sierra may simply be the fastest truck out there.
Damage Resistance: 10/10
