Ram Truck has released information on the 2014 Ram line of vehicles. Here are the changes, by vehicle.

2014 Ram 1500

As we have reported in the past, the Ram 1500 is getting a 240-hp, 420-lb-ft, 3.0-liter light-duty EcoDiesel engine backed by the eight-speed TorqueFlite automatic. The regular 1500's base price with the 3.6-liter V-6 will be $25,295 (including destination); opting for the diesel adds $2850 above the price of a similarly equipped Ram with the 5.7-liter V-8. With the 5.7-liter and the six-speed automatic, the price goes up to $24,605. (Yes, you can get the V-8 for less than the V-6, but without the TorqueFlite automatic.) For the 5.7-liter with the eight-speed, it's $26,945, and the starting price of the diesel is $30,180, but the EcoDiesel isn't offered in short-wheelbase regular cabs. This price is for the regular cab, rear-drive long-wheelbase truck with the eight-foot bed.

New for 2014 is the front park assist system, which uses four sensors in the front bumper to detect objects that are as much as 47.2 inches away. In addition, the Ram uses a capless fuel filler. Plus, the 2014 Ram will be the first in its class to use F1234yf refrigerant in the air conditioner, which is said to help reduce greenhouse emissions. The 2014 Ram 1500s go on sale in the fourth quarter of 2013.

2014 Ram 2500/3500 Heavy-Duty

The Ram 2500/3500 will be available with a larger gas engine starting in 2014. The optional 6.4-liter Hemi, the largest-displacement V-8 in 3/4- or 1-ton trucks, puts out 410 hp at 5600 rpm and 429 lb-ft of torque at 4000 rpm. It features VVT with Fuel Saver cylinder deactivation. The 6.7-liter Cummins returns, now using Diesel Exhaust Fluid to improve emissions. It's still backed by either a manual or automatic transmission. Other new features include new gooseneck/fifth-wheel capability for the 2500, dual alternator systems (up to 440 amps), and new 18- and 20-inch wheels. The Power Wagon benefits from the new 6.4-liter V-8 and unique three-link front suspension, in addition to getting the new rear suspension in the rest of the 2500 line. That includes a five-link coil setup with the option of air suspension on 2500s. The 3500s add the option of supplemental airbag suspension. Max towing capacity for the Heavy-Duty trucks is 30,000 pounds, max payload is 7320 pounds, and max GCWR is 37,600 pounds (all with the 3500). A new option on Crew Cabs, a flat load floor uses fold-out panels that create flat surface across the floor. The Ram 2500 Heavy Duty starts at $30,695; if you want the 6.4-liter Hemi, add $1495 over the price of a similarly equipped Ram with the 5.7-liter Hemi. Production is scheduled to begin in the third quarter of 2013.

2014 Ram 3500, 4500, and 5500 Chassis Cab

For the commercial side of things, the Ram Chassis Cab boasts best-in-class GCWR, plus new engine availability. With the 3500, GCWR is up to 30,000 pounds, with a max trailer weight of 22,750. Those numbers go up to 32,500 and 24,650 with the 4500, and 37,500 and 29,600 with the 5500. Ram 4500 and 5500 Chassis Cabs are now available with gas or diesel engines, with the new option of the 367-410-hp, 429-lb-ft, 6.4-liter V-8. The 3500 comes with a choice of two gas engines or the Cummins with a manual or automatic. With the gas engine, there is left- or right-side power-takeoff capability with the Aisin AS66RC automatic transmission. In PTO mode, the Fuel Saver and cylinder-deactivation systems are activated for improved fuel efficiency. A 440-amp dual alternator system is also available. The Cummins comes with a "smart" exhaust brake, and the Chassis Cabs offer an exclusive front-axle disconnecting system.
