You didn't read the article did you, has far less electrical, mechanical and moving parts than a regular engine and its a 2.5L that weighs 300lbs vs a cummins that weighs 1100lbs. Measures around 42"X22"X18". Typical post on this forum these days judge before you know. The only thing I want to know is how it holds up, navistar has already picked it up and its ready for production so we should know soon.
