Variable Torque Motors - American Made Efficiency. One of the largest down-sides to electric motors is their inherent efficiency range and, in hybrid systems, the drag they can create on the drive train.
In lighter-duty vehicles, the 6.4 Hemi is rated at 410 hp at 5,600 rpm, with 429 lb-ft of torque at 4,000 rpm. Variable valve timing uses a hydraulic cam phasing system under computer control (developed by Chrysler). The camshaft has oil passages in front to drive the cam phaser sprocket.
