The EPA rates the range of the 2014 Chevrolet Spark EV at 82 miles on a single charge, equivalent to 119 MPGe. However this figure is based on normal driving conditions. According to Chevrolet engineers, under ideal driving conditions the Spark EV could theoretically travel about 160-180 miles on a single charge.
When Digital Trends got word of this, they had to try it out. The engineers told them it would require driving for about nine hours straight at a leisurely pace of 18.5 mph. So they went to a racetrack, disabled the MyLink system and climate control in the Spark EV, inflated the tires to their maximum recommended level and set off to see how far they could really go on a single charge.
After 6 hours of monotonous driving at speeds that would put your grandmother to sleep, the Spark EV finally ran out of juice. It had completed 139.7 miles of driving off of a single charge, nearly 60 miles more than the estimated range for regular driving.
Digital Trends says a room full of Chevrolet engineers gasped collectively when they heard of their achievement. They asked them if they had set a record, but Chevy wouldn’t say, apparently out of fear that they would upset the EPA. So we’ll call it an unofficial record.
