    7.3L OHV PFI GAS V8

    Design a gas-powered V8 built for strenuous duty, hauling heavy loads day in and day out, with commercial-like durability, performance and efficiency. The answer: the port fuel-injected 7.3L. This big-block “pushrod” V8 utilizes variable-cam timing to produce high end power low in the rpm range to provide the responsiveness and efficiency commercial applications require. The 7.3L size was chosen due to its ability to perform optimally under heavy load, which further adds in efficiency. And for the durability also required, the 7.3L features a new cast iron block with four-bolt and cross-bolted main bearings plus a forged steel crankshaft.

FORD TORQSHIFT® -G 6-SPEED AUTOMATIC TRANSMISSION

The standard 6.2L gas V8 in the F-250 is teamed with the Ford TorqShift® -G 6-speed automatic. Experience responsive power delivery and seamlessly smooth shifting. The SelectShift® feature includes Progressive Range Select (for overdrive lockout) plus Full Manual. Tow/Haul minimizes gear hunting uphill; downhill, it prevents upshifting and gaining speed, and reduces reliance on brake pressure to slow the vehicle.

DIESEL ENGINE-EXHAUST BRAKING

The available 6.7L Power Stroke® Turbo Diesel incorporates a driver-activated engine-exhaust brake. It restricts the turbocharger’s exhaust flow to generate back pressure and slow the vehicle, providing greater control while travelling downhill, regardless of vehicle load or road grade. Also, because the engine brake helps minimize having to apply pedal pressure, brake fade and lining wear are reduced, lowering the cost of maintenance. Three settings are available: On, Off, and Auto. The Auto setting modulates engine braking as needed to help maintain the speed you want based on accelerator and brake pedal use.

OPERATOR-COMMANDED REGENERATION WITH ACTIVE INHIBIT

Some operating conditions, such as long idling, don’t generate enough engine heat for the diesel to automatically burn off soot in the diesel particulate filter. That’s where available Operator-Commanded Regeneration with Active Inhibit (diesel only) comes in. When the warning light comes on, pushing the activation button raises the exhaust temperature to burn off the soot, after which the exhaust temperature reverts to normal. The Active Inhibit feature allows delay of regeneration when the vehicle is sitting over combustible materials such as dry leaves or grass. Once in a safe place, the driver can manually start the regeneration process. Recommended for commercial applications.
