This is due to the first law of thermodynamics which is the law of conservation of energy. The energy used in burning gas in a car will be the same as the energy used in a stove assuming the smae mass used. In the car, the energy is transformed to heat and work while as in a stove its only converted to heat.
Since the same mass is used and assuming equal losses, it would be safe to say that the heat has a higher value in the stove since the energy from the gas in the car is divided into work and heat.
