Special Forces teams are all about silently penetrating remote areas and executing complex, lightning-fast raids. Now DARPA is developing a new vehicle to soundlessly race commandoes to their missions: stealthy, hybrid-powered motorcycles.

The idea is to develop a hybrid power system that relies on both electric and gas power, allowing special ops to go off-road and zip past enemy forces with the silence of an electric engine, while also being able to handle extended missions and higher speeds with a supplemental gas tank.

In February, DARPA awarded Logos Technologies a $100,000, six-month Phase I Small Business Innovation Research (SBIR) contract for a preliminary design to see just how viable the project is.

Horses can be pretty stealthy too. Will Tonto be guarding the unguarded keyless electric bikes? What an effing waste of tax payer money.   :facepalm:

I can see how in certain situations these things might be handy.  Of course the price tag will undoubtedly be in the tens of thousands per unit once they are built.

DARPA has a pretty good track record of seeding cutting edge research.
A lightweight, hybrid powerplant seems like a worthy objective, and $100K, a small enough buy-in...

Enough curmudgeony around here. Embrace tech.  And hey... you're reading this because of DARPA.

This could be good for us.  Darpa has a strong directive to prove technology then work to get the technology out to both the military or the public sector.

I'm ready for a hybrid dirtbike.

Imagine in several years, these noisy, loud, gas-powered ATVs used by sportsman and hunters could be replaced with quiet electric ATVs. No exhaust fumes. No spooking game. It might bring some semblance of peace and quiet back to the woods again.   :thumbsup: :thumbsup:

Bring it on DARPA.

I would take one in a second.  Light weight, massive range, flexible fueling, electric only for the city.  It could be the perfect dual sport.   :drool:

A small propane engine powering a brushless generator that powers the motor directly seems like a decent idea. Where's that? Anyone build that yet?

The only problem with propane is the need for a high pressure canister to hold the fuel, which would add weight and explosiveness.  Also, diesel is more energy dense, so you don't have to carry as much for the same range.
