The Power Stroke Super 600, which powers the Mighty F-350 Tonka concept truck, is a turbocharged 32-valve OHV V-8 beast that produces an estimated 350 hp and 600 lb-ft of torque, thanks in part to a new turbocharging concept called electronic variable-response turbocharging (EVRT). This system employs a set of vanes inside the turbocharger housing that automatically adjust their pitch to optimize airflow within the turbocharger. This engine is mated to an all-new five-speed PowerTorq automatic transmission that features First and Second gears with low ratios that will make it easier to launch a truck that’s loaded with cargo—and also should work well in four-wheeling situations. No word on when this new powertrain might actually make it into production though we suspect it will appear sooner rather than later. For now, Super Duty buyers will have to make do with another new engine announced at the show: the Power Stroke 525, which develops 250 hp and 525 lb-ft of torque. Availability of that engine began in January. View Related Article
