Ram's most capable pickup truck boasts 930 pound-feet of torque.

Ram has made the 3500 Heavy Duty pickup truck even more capable for the 2018 model year.

Power still comes from a 6.7-liter Cummins straight-six turbodiesel engine, but it now generates over 385 horsepower and 930 pound-feet of torque. The latter figure is a record in the segment. The Chevrolet 3500 HD boasts 910 pound-feet of torque from a 6.6-liter Duramax turbodiesel V8, while the Ford F-Series Super Duty is equipped with a 6.7-liter turbodiesel V8 whose torque rating checks in at 925 pound-feet.

The company explains its engineers squeezed out an extra 30-pound-feet of torque from the Cummins by making tweaks to the turbocharger and to the fuel delivery system. The oil-burner continues to channel its power through an automatic transmission.

The updated turbodiesel engine lets the Ram 3500 tow 30,000 pounds when it's equipped with a special fifth-wheel hitch. The hitch was designed by Ram Engineering specifically for the 3500, and it's priced at $1,395.

Buyers who would rather stick with a conventional hitch can tow 20,000 pounds. Alternatively, installing a gooseneck hitch raises the towing capacity to 31,210 pounds.

The 2018 Ram 3500 will begin arriving in showrooms nationwide before the end of the month. Pricing hasn't been announced yet.
