All you have to do is check out the EPA's website and use the comparison tool to figure out if one car is more efficient than another. It will even tell you how much you'll save on fuel costs per year and over a five-year period. Click the comparison link above and plug in the Tesla Model 3 and Nissan LEAF and check out the results. However, in the real world, there are many variables that impact vehicle efficiency.

One such variable is changing elevation. While EVs aren't affected by the thin air like ICE cars, moving any vehicle up a steep road and against the forces of gravity is going to cause an efficiency hit.

The Fast Lane Car just took ownership of its new Tesla Model 3 Long Range AWD. They put the car up against a new Nissan LEAF Plus to see how the two fare as far as range is concerned while driving up a mountain. It's important to note that the LEAF is a single-motor, front-wheel-drive car. In addition, TFLcar assures that both cars begin the trip with exactly 236 miles of range.

Check out the video and let us know your takeaways in the comment section below. We think you might be surprised by the results.
