Nah, sounds good on paper but not practical, and it don't substitute for cubic inches, nothing does!

The Hydrogen 7 was based on the 760Li model and featured two tanks: one for hydrogen and one for gasoline. The 6-liter V12 engine under the hood was modified so that it could use both fuels. Unfortunately, the efficiency the car had on hydrogen was extremely low, returning about 5.6 mpg (50 l/100km) on average, mostly due to the difference in energy density between petrol and hydrogen. Even so, the green character of the car was evident as CO2 emissions were eliminated completely.

Two fuel systems, one 12-cylinder engine

Powering the Hydrogen 7 is a 256-hp 6.0-liter V-12 (the same engine in the 760Li makes 438 hp) with a "dual-mode drive system" that allows it to tap either its 19.5-gallon gasoline tank or a 17.6-pound liquid hydrogen tank for its juice. The driver can switch between fuel sources via a dashboard switch; if one tank runs empty, the system will automatically switch to the other. This complex switching involves not just separate tanks, but unique delivery channels and an additional network of valves in the cylinder head. The hydrogen tank carries enough liquid hydrogen for 125 miles of squeaky-clean motoring, with the gasoline tank good for another 300 miles.

Uses more fuel that a yellow AU Falcon on mixer ring LPG setup and is still slower
