There's still no commercial technology to use LNG in vehicles (it must be kept at -162 deg, sort of). Here in Brazil, cars that use gasoline (with 20-25% ethanol) can be adapted to use natural gas (under pressure).
BTW, Otto cycle motors can easily use anything from natural gas to gasoline, including LPG or ethanol. Brazilian new "tetraflex" cars can use ethanol, E25 blend (25% ethanol, 75% gasoline - the standard "gasolina" in Brazil), natural gas or pure gasoline (not available in Brazil, but available in our neighbouring countries). They just don't use LPG because it's forbidden by law (LPG is "social", the price is kept low, because if the poor people don't use LPG for cooking, they will destroy the forests and use wood). Diesel cycle motors, OTOH, require a different type of fuel, like gasoil, standard biodiesel (esthers of fatty acids and methanol or ethanol) and even vegetable oils (esthers of fatty acids and glycerol).
