The 2015 Ram 2500 belongs to the fourth-generation Ram lineup. It is a sturdy heavy-duty pickup truck designed for both workhorse and comfort needs. The 2500 offers three engine options: a 383-hp, 5.7-liter V-8 engine; a 410-hp, 6.4-liter V-8 engine; and a 6.7-liter turbo-diesel six-cylinder with 350–385 hp. All engines are paired with a standard six-speed automatic transmission, and four-wheel drive is optional. Available in six appealing trims—Tradesman, SLT, Big Horn, Laramie, Laramie Longhorn, and Limited—the Ram 2500 features an infotainment system with Uconnect technology, Bluetooth, and optional navigation. Additionally, notable safety features include standard front-seat and full-length side curtain airbags, stability control, and a tire-pressure monitoring system. Though there were no significant changes from the previous model year, the 2015 RAM 2500 continues to be praised for its powerful engines, high-quality interior, and excellent ride quality.
