Low weight, highly streamlined.
Evomoto is getting 1L/100km - and he's on here BTW. ;-) - but that's on a 2 wheeled recumbent motorcycle.

Yes low weight, highly aerodynamic are two pieces of the puzzle.
1,200 lbs or less is the number I am stuck on and .14 to .18 is the coefficient of drag range that will be needed. Closer to the .14 the better
A small displacement ICE is definitely required to even remotely have a chance! For me I am selecting a diesel as it gives me more options such as using biodiesel. However the main reason is diesel has more BTU in comparison to gas and this equals greater driving distance and MPG potential. Diesel engines are also more efficient than gas engines which also helps it to get better fuel economy potential. Next get everything that can be electrified off the engine such as fuel and water pumps, AC compressor, and fan etc..
Thin tall low weight wheels with Low weight LRR tires are a must as well which will be slightly over inflated!
Customized very tall overdrive gearing. .63 5th gear with 3.27 rear diff for a final gear ratio of 2.06
Finally add in hybrid capability and you have the recipe for 1 liter potential! You burn the most fuel during idle and acceleration. Let the electric motor handle these tasks for which it excels at and add into the mix the opportunity for regenerative braking while at cruise and when the diesel engine is shut down! This plays right into advanced ecomodding driving characteristics which we should all learn to incorporate into our driving routines anyways.
A few other things in the tricks bag should get us there considering the VW XL1 is nearly 1,800lbs and has a coefficient of drag at .18 and pulls off 1 liter performance. I will be at 1,200lbs and hopefully under .18 Cd. I will also be using a smaller diesel engine than the XL1. So we will see soon enough if my strategy and game plan is enough to pull it off
