Daimler’s Smart car, the ForTwo, currently being delivered to early adopters in the U.S., is touted as an environmentally friendly and efficient way to get about town. With the 70 horsepower three cylinder hauling over a ton (driver and maybe a bit of cargo included) performance reminds me of the classic VW commercial which went “0-60, yes!” The bigger disappointment is the claim of not much above 40 mpg in normal use, with the distinct probability that winding the 1.0-liter DOHC power plant in search of highway speeds will drop that expectation to a mid 30s reality. Neither Honda or Toyota are quaking at the introduction of the ForTwo.

However, quietly puttering away in Hesperia, California, Hayes Diversified Technologies has been delivering a machine that not only can run at 55 miles an hour all day but does it at close to 100 mpg. Granted, the luggage capacity leaves something to be desired on the diesel powered Kawasaki KLR based motorcycle, but for those with a helmet and a burning desire to minimize their carbon footprint HDT’s MD670F “Bulldog” makes a compelling argument. Based upon their successful military machines used by the ground forces in Iraq, the Bulldog will be a civilized version able to run on just about any form of diesel. A recycle deal with your local purveyor of french frys and you could be spending less on your transportation fuel bill than you do on bottled water. Unfortunately the military organizations about the world have also come to appreciate the capabilities of HDT’s 30 horsepower, 369 pound enduros so production of the street version has been delayed until at least 2009. Battle tested, incredible mileage, a top speed of more than 90 mph, and potentially the smell of french frys from the exhaust, now that’s environmentally friendly.

I looked into one about 3 years ago. (The last time that they said they would have a civilian version in 1-2 years) At that time they wanted $19K. So they take a $6K motorcycle from Kawasaki, replace the engine with their own diesel, and change an extra $13K. That must be one very special engine.

BTW the gasoline KLR gets about 60 mpg at a steady 55 mph.

Great for the marines; I shudder for the road. A diesel motorcycle? Yuck.

At that time they wanted $19K

Ouch!

Forget that… It looked like an interesting novelty, but for that kind of money you could have a KLX, a Buell Blast(1), and a used truck in good shape.

(1) Okay, I am not a sports biker.

[…] isn’t the only diesel-powered motorcycle that we’ve ever seen, but it might be the quickest. Built by California-based industrial arts […]

The information I received from them went something like this… The $19k 3 years ago was for a “special limited edition” KLR. They were going to produce less than 50 civilian models. The plan changed as people inquired about the bike and they were going to start “regular production” of the civilian model with a projected price around $7000. Sadly the war has continued and their production has needed to be solely focused on military applications.
