Electric vehicles vs gasoline vehicles

Will an electric vehicle use less joules going up a hill than a gasoline vehicle, because electric vehicles are more efficient? I've read that electric vehicles use on average 800,000 joules per mile, while gas vehicles use 3.3 million joules per mile. Assuming those numbers are based on horizontal tests, I'm wondering how many joules each would use going up a 15 degree incline, for a total rise in elevation of 600 feet, and both vehicles weigh 3,000 pounds.

Look up the efficiency of gas vs electric motors, then apply that to the physical energy required to "lift" a car 600ft.

Will probably come close to your numbers, or at least the ratio.

The whole field of transport costs is affected by Tax as much as basic efficiency.The secret of cheap transport is to use a fuel that is not taxed. Of course, you may need to produce a special engine to utilise that fuel. Life is never simple.

When comparing electric and chemical propulsion, it may or may not be relevant to compare the performance of the whole energy chain, rather than just to compare the energy supplied 'to' the vehicle, depending on what answer you want to get.
