A mid-year upgrade to the Ford F-Series Super Duty's diesel engine delivers a boost in horsepower and mpgs. According to a Ford press release, these upgrades add up to deliver the most powerful diesel engine ever installed in a heavy-duty pickup.
New 2011 Ford F-Series Diesel Engine
Debuting in April 2010, the 2011 F-Series initially came with a hefty 6.7-liter Power Stroke V-8 turbocharged diesel engine. This engine remains for the mid-year upgrade. However, a few tweaks have streamlined performance to maximize torque and reduce fuel consumption.
Add it all up, and the new diesel Ford F-Series specifications come in at a best-in-class 800 lb-ft. of torque and 400 horsepower. Ford is also quick to point out that the upgrades help the Super Duty edge out the towing and payload capacities of the current segment leader - the Chevrolet Silverado 3500.
In terms of fuel efficiency, the upgrades help the 2011 F-Series deliver an impressive 20 percent boost in mileage over the 2010 model.
The tweaks add up to:
- An increase of 65 lb-ft. of torque
- An additional 10 horsepower
- A two percent increase in fuel mileage
Free Engine Upgrades to Current 2011 F-Series Owners
For those who have already purchased a 2011 Ford F-Series Diesel, Ford is offering a free software upgrade that will deliver the new specifications to current owners. Ford plans to mail out notifications of the free upgrade, which will require a 30-minute software adjustment to the vehicle's powertrain control module.
Upgrades will be available at Ford dealerships staring August 31.
