I fully charge a 2020 Nissan LEAF SL Plus and drive it at a steady 70 mph (113 km/hr) to see how far it will go. Some notes: The temperature was between 68 and 75 degrees during the drive, the tires were at the manufacturer's recommended 36 psi, and there was a slight crosswind of about 9mph.

I drove up and down the NJ Turnpike in a loop and ended up very close to where I started. It's important to note that no EV range test is perfect and that EV range is dependant on a lot of different factors. However, we conduct these range tests to offer EV owners a guideline as to what range they can expect to see under similar driving conditions.

When it was all over, the LEAF went 185.4 miles and the vehicle was at 1% state of charge. I averaged an efficiency rating of 3.4 miles per kWh over the 185-mile trip at 70 mph.
