The 2015 Ram 4500 is a commercial-grade, ultra-durable chassis cab truck. Perfect for heavy-duty tasks, it's hard to beat the 4500 when it comes to towing capacities and overall strength. It is powered by a 6.4-liter HEMI V8 engine with 370 horsepower, 429 lb-ft of torque or an optional 6.7 liter Cummins diesel engine that touts 325 horsepower and a massive 750 lb-ft of torque. Both engines come paired with a best-in-class 6-speed automatic Aisin transmission. In terms of technology, it includes features such as a multiview display and Uconnect® Access System to enable comfortable, well-connected hauls on the road. Its blend of raw power, advanced technology, and robust design made the Ram 4500 a solid choice for those in need of a capable commercial vehicle in 2015.
