After Schwa's interesting post regarding VW's 235 mpg concept car L1
https://www.greenhybrid.com/discuss/...cept.2676.html

here's another interesting crazy concept car,
the PAC-Car II developed by the Swiss ETH Zurich university:

This vehicle is a fuel cell extreme single seater technology demo concept vehicle.
It uses hydrogen, has a Cd of 0.09 (!) and a fuel consumption rate of.....:

3836 km / litre of hydrogen


That means, with less than 10 litres of fuel, this vehicle could circle the planet!
ok, so it's not the most practical of vehicles.

By comparison, the L1 would be very practical (and would look to be much more comfortable)
