A new era in Ford diesel technology arrives with the unveiling of the company’s latest 6.7-liter Power Stroke V-8 turbocharged diesel engine. Set to debut in the 2011 F-Series Super Duty pickup truck, the new diesel engine is expected to deliver significant improvements in torque, horsepower and fuel economy while adding more fueling flexibility and helping Ford meet stringent new emissions requirements.

So far Ford isn't releasing much in the way of numbers for either power or efficiency of the new engine other than to say that it is both more powerful and more efficient than the engine it replaces. What we do know is that the engine features several automotive-industry first for a modern production diesel engine.

These include an ‘inboard exhaust’ architecture and a unique ‘single-sequential’ turbocharger with a double-sided compressor wheel mounted on a single shaft.

This turbocharger design allows the single unit to deliver the benefits of a twin-turbocharger system in a smaller, more efficient package, combining the benefits of a small turbocharger (faster response) and a large turbocharger (ability to compress and force more air into the engine for more power) in one unit.

The engine also gets a high-pressure Bosch fuel system that injects diesel at up to 30,000 psi and aluminium cylinder heads for reduced weight.

One of the obvious visual differences in the new 6.7-liter Power Stroke V-8 turbocharged diesel engine is the layout of the pipes. The exhaust manifolds, for example, reside in the valley of the engine instead of outboard, while the intake is outboard of the engine. The cylinder heads are essentially flipped around in comparison with previous V-8 engine architectures. Advantages include a smaller exhaust system and improved cooling.

  1. Can not wait to see the torque numbers on this engine, reportedly it will be over 700 ft lbs.

  2. I've seen examples of "reverse induction" small-block Chevys, with multiple small carbs where the exhaust manifold should be and 6 foot straight pipes coming out of where the intake should be. Pretty cool stuff, and now manufacturers are following suit, though I'm sure the Ford will be a bit more complex. Looking forward to performance stats!

  3. I agree but they can reduce the stroke of the pistons to further reduce the displacement for example.
    I was thinking of de-tuning half of the V8, like Toyota did/does with their 4-cylinder. The same basic engine was used for both the Corolla and the Celica, but the Celica was tuned for more performance in the same way, longer stroke, more fuel in the mix, etc. The engine went from a 1.8L to a 2.2L in the same block with a few mods.
    Think of the torque that a Cobalt SS or something would have with one of those diesels though, man……
