The 2017 GMC Sierra 3500 is part of the model's third generation that started in 2015. It's a heavy-duty truck that offers serious towing and hauling capabilities. The Sierra 3500 comes with two engine options: a 6.0L V8 producing 360 horsepower, and an available 6.6L turbo diesel V8 engine that churns out a hefty 445 horsepower and 910 lb-ft of torque. Both engines come mated to a 6-speed automatic transmission, with rear-wheel drive standard, and four-wheel drive is an option. Available in 4 trim levels - base, SLE, SLT, and the upscale Denali, there's a wide choice depending on your needs and budget. Notable features include a standard 7-inch or optional 8-inch color touchscreen, OnStar with 4G LTE and built-in Wi-Fi hotspot, Apple CarPlay, and Android Auto. Plus, optional safety features like forward-collision alert and lane-departure warning are appreciated modern touches on this capable workhorse.
