In the dark days of the polio epidemic era, those who were stricken by the virus the hardest were left to spend the rest of their lives inside an iron lung. This medical device mimicked the way the human lung draws in and expels air through negative pressure. One version, the Both respirator, was briefly linked to the automotive industry when William Morris built 1,700 of the iron lungs, donating them to hospitals throughout the then-British Empire.
Chrysler’s version of the human lung isn’t meant for polio patients, but for the CNG-burning Ram 2500 and, perhaps, beyond.
Nothing is more American than the pickup truck. If the stars and stripes thing ever gets old, they will probably get replaced by a RAM / GM / Ford montage. The other thing that’s quintessentially American is an arms race. No, I’m not talking military hardware, I’m talking about the eternal RAM vs Chevy/GMC vs Ford tuck wars. Who has the best frame? Who has the best engine? Who can haul the most? Be prepared to draw your weapons and click past the jump. Chrysler sent me a 2013 RAM 3500 for a week and then invited me to taste test the refreshed 2014 model for a day.
If you want a diesel engine but don’t want to spring for a heavy-duty pickup, your only option is the Ram 1500.
