16. Ford 6.8-Liter Power Stroke V8
The only diesel engine on this list is the Power Stroke V8, which Ford produced from 2011 to 2015 for their trucks. International Harvester produced the previous generation of Ford diesel engines, but the company received many complaints about the engine and its quality. So the company decided to design the next generation in-house to iron out all its flaws. Although it isn’t a new V8, you still can find them all over America, and with low mileage too.
The 2011 Power Stroke was tougher than any other V8 diesel engine on the market. They fixed the fuel and intake systems and the new powerplant delivered 390 HP and 738 lb-ft of torque. Besides the big power and great performance, the 6.7-Liter Power Stroke V8 also delivered an efficient fuel economy. It was also quiet-running and powered anywhere in its rev range. After the 2015 upgrade, which included a new turbo and engine management system, the fantastic V8 diesel delivered 440 HP and a massive 860 lb-ft of torque.
