These "news" got to mass media in our country only last month
I made some calculations regarding this are these correct?
Ford Mustang GT:
E85=23MJ/l=6,4kWh
Cd=0,38 (air drag)
A=1,939 m2
Cr=0,01 (tire drag)
Mass=1300kg
rho= 1.22 kg/m^3
v=100 km/h=27.7 m/s
g=9.81 m/s2
Calculation:
Fd=-Cd*A*0.5*rho*V^2
Fr=Cr*mass*g
Fd=345 N
Fr=127 N
Fsum=472N=47,2 MJ/100km
Only with 100% Q it gets 2L/100km. As about 60% of all energy are used to overcome air drag then including other losses in transsmision and electrical loads the minimum possible MPG is 3.33 L/100km. Remember that this is with 100% thermodynamically efficiency but he claims 2,14 L/100km (MPGe) or 4,6 L/100km (MPG) so the engine efficiency should be around ~70% which I think is thermodynamic limit for steel engines. Looks almost feasible but it should require radical engine modifications.
