2019 Ram HD Debuts With Cummins 6.7-Liter Turbodiesel

2019 ram 2500 for sale – Engines: 6.7-liter Cummins High Output Turbo Diesel reaches 1,000 lb.-ft.
With a long list of upgrades, the new Cummins 6.7-liter I-6, high output Turbo Diesel delivers up to 1,000 lb.-ft. of torque @ 1,800 rpm and 400 horsepower @ 2,800 rpm. Changes begin at the core, with a cylinder block made from compacted graphite iron. Overall, the new Cummins Turbo Diesel weighs more than 60 lbs. less than the previous-generation engine, yet delivers more power and torque. A new cast-iron cylinder head builds on the new block with changes that include new exhaust valves and springs, and new rocker arms. Lighter and stronger pistons include new low-friction rings and connect to the crankshaft via newly design forged connecting rods and new bearings. An all-new exhaust manifold is the mounting point for an improved variable-geometry turbocharger with laminated heat shields, delivering boost pressure up to 33 psi.

The second variant of the Cummins Turbo Diesel also gets a performance boost with 370 horsepower @ 2,800 rpm and 850 lb.-ft. of torque @ 1,700 rpm.
The standard engine in the 2019 Ram 2500 and 3500 Heavy Duty is upgraded to the proven and potent 6.4-liter HEMI V-8, delivering class-leading 410 horsepower @ 5,600 rpm and 429 lb.-ft. of torque @ 4,000 rpm to handle the payload and towing requirements of the heavy-duty truck user.

Transmissions
Ram 3500 Heavy Duty models equipped with the 1,000 lb.-ft. high output Cummins 6.7-liter Turbo Diesel employ the Aisin AS69RC electronically controlled six-speed automatic. This transmission is engineered to handle the colossal torque of the Turbo Diesel engine and increased vehicle weight ratings while delivering improved shift quality. Along with hardware upgrades, the Aisin AS69RC uses a new transmission controller with double the memory of the previous controller and a dual-core processor. This delivers faster, more precise shifts under all driving and loading conditions.

Ram Heavy Duty trucks powered by the standard output Cummins 6.7-liter Turbo Diesel are equipped with a significantly upgraded version of the 68RFE six-speed automatic transmission. Changes designed to improve the electronically controlled transmission’s shift quality include new variable-force solenoid controls for the torque-converter clutch. A new reverse accumulator improves shift feel when placing the transmission into park from reverse. Drive-to-park shifts were also improved through refined hydraulic control.

In a first for the Ram Heavy Duty, the 6.4-liter HEMI V-8 comes mated to the proven and smooth-shifting TorqueFlite 8HP75 eight-speed automatic. There are more than 40 individual shift maps to optimize shift points for fuel economy, performance and drivability. The transmissions use shift-by-wire technology, eliminating a mechanical linkage between the transmission and the gear selector. The 2019 Ram Heavy Duty uses an innovative rotary e-shift dial mounted on the left side of the instrument panel’s center stack – freeing up space traditionally occupied by a console- or column-mounted shift lever.
