A recently published test by Tony Williams indicates that the 2014 Chevrolet Spark EV has at least 10% more range than the Nissan LEAF at a steady 62 mph.

It should be noted that the Nissan LEAF has a 75 mile EPA range rating, while the Chevy Spark EV is at 82 miles.

This test was conducted on an 80-mile loop through San Diego at 100km/h ground speed (62mph).

In the video description, we can read:

"It did very well in comparison to the Nissan LEAFs that have been tested on the same course."

Of course, both vehicles are wildly different, but the Spark EV does have a lower capacity battery pack - 21.3 kWh  vs. 24 kWh in LEAF - so this real-world test-loop result is interesting and shows that perhaps the Spark EV is more ideally suited to racking up the range miles at highway speeds.

Tony earlier did a 2013 v 2012 Nissan LEAF range test, that report can be found here.
