Specifications of RAM 2500 Crew Cab II (DT) 2500 6.4 Hemi V8 (410 HP) Automatic
General characteristics of RAM 2500 Crew Cab II (DT) 2500 6.4 Hemi V8 (410 HP) Automatic
With so many available configurations, exterior dimensions vary across the range for the 2021 Ram 2500. Regular Cab models come only with an eight-foot box and have an overall length of 232 inches. For these models, the wheelbase comes in at 140 inches. Ground clearance is 13 inches or 13.1 inches for 4x4 variants. Width is 83.5 inches in this configuration, and height varies between 78 inches and 80.2, depending on the drivetrain.
Crew Cab variants can be had in either box length. With the shorter 6'4" box, the wheelbase is 149 inches and length is 238.8 in. These grow to 169 inches and 260.8 with the 8' box selected. Ground clearance ranges from 11.1 inches to 13.1, with either 4x2 or 4x4 drivetrains selected. Height maxes out at 80.1 inches. The Power Wagon variant shares the same dimensions, although it is slightly taller at 80.9 inches, and boasts a ground clearance of 14.2 inches.
The Mega Cab style is available only with the smaller box length, resulting in a 160.4-inch wheelbase and a total length just a smidgeon under 250 inches. Height and ground clearance are 80.1 inches and 13.1 inches, respectively.
The base weight across the range starts at 5,524 pounds for the entry-level model, and tops out at 8,069 lbs for the heaviest trim.
The engine options from last year carry over for this model year, namely a 6.4-liter V8 with outputs of 410 horsepower and 429 lb-ft of torque as standard, or a 6.7-liter Cummins turbodiesel inline-six with 370 hp and 850 lb-ft. Buyers can choose between 4x2 and 4x4 for most trims - only the Power Wagon is 4x4 exclusively as is any trim optioned with the Mega Cab body. Trucks are hardly expected to offer smooth engines that purr in refinement, and heavy-duty haulers such as this are designed to be efficient, functional and hard-working, with the capability to perform - not in terms of acceleration, but in terms of powerful hauling and carrying. As such, the Ram 2500 is pretty damn good. Towing up to 19,780 pounds is possible with the turbodiesel engine and the correct towing attachments, besting the GMC Sierra 2500 HD, but not quite managing the 22,800 lbs of the Ford F-250. Even the default powertrain can manage in excess of 17,500 lbs. Although the 2021 models have not yet been run through acceleration tests, the 2019 model in Regular Cab Tradesman configuration with the turbodiesel engine managed the 0-60 mph trial in 7.2 seconds - marginally better performance than its Ford Super Duty rival.
Carrying over from 2019's substantial upgrade, the five-link rear coil springs and the frequency response damping shocks have added immense value in one critical area: comfort. Big trucks are designed more for functionality and to work hard, so it makes a nice change to tangibly feel an improved ride quality and better handling, whether or not the cargo box is filled to the brim. In many comparisons with competitors such as GMC's Sierra or Ford's F-250, the Ram 2500 truck provides a much smoother ride with better road-holding and a confidence-inspiring sense of gravity. It also does really well in terms of isolating the cabin from rougher road surfaces. The Power Wagon trim is worth a special mention for its added off-roading prowess, and is exclusively available in 4x4 configuration with more than 14 inches of ground clearance. As further testament to Ram's commitment to passenger contentment, there is also an optional air suspension which can be fitted to 4x4 models to further enhance comfort levels.
Steering is light for the express purpose of making it easy to maneuver this large lump around, and it does so admirably in low-speed settings. At higher speeds and on the highway, there's a rather numb sense to the wheel, but it tracks straight and responds to input, albeit a little slowly.
Like all heavy-duty haulers, the new Ram 2500 isn't rated by the EPA, and pinning down an exact figure for gas mileage is almost impossible. Buyers of a car like this have varying uses for these trucks, and, depending on what you do with it daily, and how you drive it, your fuel economy estimates can vary greatly. Owners of Ram 2500 trucks report that the 6.4 liter V8 manages anywhere between 13 and 14 mpg combined, while the bigger diesel motor can achieve upwards of 15 mpg. The standard fuel tank size is either 28, 31, or 32 gallons depending on the engine and body style. With the V8 gas engine and the 31-gallon tank, the range won't be much more than 434 miles. Additionally, Crew Cab variants set up with the eight-foot bed can have a 50-gallon fuel tank optioned on - a new update last year - which will substantially improve the distance between fill-ups.
The most basic Ram 2500 model comes with a Black/Diesel Gray interior and heavy-duty gray vinyl as standard, although black cloth can be applied optionally. One model up, the Big Horn, allows for premium cloth bucket seats or bench seating in Diesel Gray, Light Mountain Brown or combination black and Frost Beige, while the mid-spec Laramie upgrades to leather in either black or a combination of Mountain Brown and Light Frost Beige. The Power Wagon trim features cloth with unique embossed tread as standard, with leather optional. The Laramie trim steps up the luxury offerings with standard leather trim and interior colors in either Mountain Brown/Light Frost Beige or Black. The top-end Limited trim can be had with black leather, or an Indigo and Frost leather duo.
