Secret Technologies in Ram Engines
The engineering behind these engines includes several exclusive technologies developed to optimize output while minimizing consumption.
The eTorque Mild-Hybrid System
The eTorque system is not a full hybrid setup like those found in sedans. Rather, it utilizes a 48-volt battery pack to:
- Enhance "Start-Stop" shifts for smooth idling.
- Capture energy during deceleration (regenerative braking).
- Provide extra torque throughout the first half-revolution of the crankshaft.
Multi-Displacement System (MDS)
Fuel economy has actually typically been a powerlessness for large V8s. MDS permits the engine to intelligently shut down half of its cylinders when complete power isn't needed, such as during highway cruising. This allows a truck weighing over 5,000 pounds to attain surprisingly competitive highway MPG ratings.
Turbocharging and the Hurricane Architecture
The intro of the Hurricane engine series utilizes two low-inertia, high-flow turbochargers. This setup guarantees that torque is offered practically immediately across the RPM variety, removing the "turbo lag" that plagued older generations of forced-induction engines.
