The 2015 RAM 3500 is a heavy-duty pickup truck offering impressive power and towing capacities. Available in six trims: Tradesman, SLT, Big Horn/Lone Star, Laramie, Laramie Longhorn, and Laramie Limited, each proposing distinct packaged features. The RAM 3500 is equipped with either a 5.7L V8 engine with 383 horsepower, a 6.4L Hemi V8 with 410 horsepower, or a robust 6.7L Cummins turbo diesel engine that cranks out 350-385 horsepower depending on the transmission choice. Speaking of transmission, there's a 6-speed manual or a 6-speed automatic transmission. It also offers two drivetrain options, either a RWD or 4WD. This model comes with key safety features, including antilock disc brakes, front and side curtain airbags, stability control and a tire-pressure monitoring system. Inside is an available Uconnect infotainment system with an 8.4-inch screen, satellite radio, and Bluetooth. However, 2015 brought no significant changes to the RAM 3500.
