We devote a lot of time on this blog to discussing new Ford vehicles and celebrated new releases or venerated classics. It’s not as often that we turn to discussing things as specific as Ford engines, but in this case, there’s a good excuse: in only a few years, the powerful 6.7-liter Ford Power Stroke turbocharged diesel V8 has reached a production number of 500,000. And the reason that this motor has come off the assembly line half a million times since its recent debut is that there’s no engine like it on the market.

The specific power plant in question—number 500,000—was installed into a 2014 Ford Super Duty F-350 Lariat. While a truck like that would be a special sight rolling through Frankfort, Ford trucks across the range are available with the 6.7-liter Power Stroke motor. It’s easy to see why this engine, rolling off the line at the Louisville, KY Ford Truck plant, has been so popular: virtually no other truck engine offers as potent a combination of horsepower (400), ft-lb of torque (800), or fuel economy. Additionally, this motor is built exclusively by Ford, ensuring that it comes with all the reliability and toughness of the Ford Super Duty line.

According to Joe Bakaj, Ford vice president of powertrain engineering, Ford “Super Duty customers are no-nonsense, no-compromise individuals,” and those “are the attributes our team took to heart when engineering this diesel engine.” Combining the Super Duty power with best-in-class fuel economy is a no-brainer for those who need powerful, workhorse truck with a motor to match. Don’t be surprised to see another 500,000 on the road before you know it.
