I'd sure like to see a diesel in a Workhorse chassis, but I'd want it to be the same price as the gas option. That's not likely to happen. I don't care how many cylinders it has or what the displacement is, just give me the torque.
What I'd really like to see is the quiet common rail fuel injected diesels I saw in Europe YEARS ago. Quiet as a gas engine (no diesel rattle), no smoke out the tail pipe, even under full throttle and torque like a diesel should have. I don't know why we haven't seen the same in the US. I swear, if you didn't actually know it was a diesel, you'd never guess. They didn't even stink like a diesel, except when you filled the fuel tank.
