It's about 53 times the energy of the best lithium ion battery.
Gasolin reacts with oxygen, so the gasoline itself have 1/3 of such energy ad the oxygen have 2/3. But cars don't need to cary oxygen like rockets need.
Combustion engines it's just 25% effective in most cars, while some electric motor can be 95% or even 98% efficient. So you have to consider it.
