14. 6.7-Liter Power Stroke V8
The only diesel engine on this list is the relatively new Power Stroke V8, which Ford produced from 2011 to 2015 to install in their trucks. International Harvester produced the previous generation of Ford diesel engines. This resulted in Ford getting 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.
The result was the 2011 Power Stroke. It was better and tougher than any other V8 diesel engine on the market. The fuel and intake systems were fixed. The new powerplant delivered 390 HP and 738 lb-ft of torque. Besides its big power and great performance, the 6.7-Liter Power Stroke V8 delivered decent fuel economy, was quiet and provided power 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.
Any car fan will tell you that a car is only as good as its engine. The engines on this list can add value to any vehicle with their power and strength.
