2019 Ram 1500 Dyno Test

Legendary HEMI power: 5.7-liter V-8 delivers 395 horsepower
The brawny 5.7-liter HEMI V-8 combines the muscle of 395 horsepower and 410 lb.-ft. of torque – in a smooth, broad power band that avoids the hesitation and peakiness of turbocharged engines – with performance-enhancing and fuel-saving technologies that include variable valve timing and cylinder deactivation.

With Fuel Saver Technology (cylinder deactivation), the engine control computer turns off fuel and spark, and closes the intake and exhaust valves on four of the engine’s eight cylinders during light load operation, such as highway cruising when full power is not needed.

Variable camshaft timing helps maximize fuel economy by reducing the engine’s pumping work via a delayed closing of the intake valve, which increases the expansion process of the combustion event.

The HEMI V-8 in the 2019 Ram 1500 benefits from a new 850-watt electric cooling fan using Pulse Width Modulation to tailor the fan’s energy draw to the cooling demand. Eliminating the traditional fan blade mounted to the front of the engine helps improve fuel economy by reducing parasitic losses and fan noise.
