The 2013 Chevrolet Silverado 3500HD is a heavy-duty pickup belonging to Silverado’s second generation. It comes in three cab styles: a regular cab, an extended cab and a crew cab. Power is delivered by a 6.0L V8 engine making 360 horsepower, or by a 6.6L turbodiesel V8 delivering a massive 765 lb-ft of torque and 397 horsepower, both coming with an automatic transmission and available with rear-wheel or four-wheel drive. It comes in four trims: the WT, LT, LTZ, and The Work Truck being the base. A highlight for this model year is the addition of a bi-fuel option on the 6.0L V8 engine, that allows it to run on either gasoline or compressed natural gas (CNG). Key safety features include a StabiliTrak stability control system, antilock brakes, and for the inside, OnStar. Tech elements include Bluetooth, a USB port, and available options for navigation and a rearview camera.
