How is it possible for a hybrid car to travel 1,554.1 miles on just half a gallon of gas? Leave it to Chevy battery systems engineer Andy Oury to find out. The Chevy employee, who leases a Volt, shared a video showing off his badge of honor. By driving in electric-only mode for several months, Oury’s Volt displayed a maintenance warning informing Oury that the engine has not been run in quite some time. In order to keep the engine lubricated, the Volt will run for a short time, and go then back to sleep. If a Volt owner does not use an entire tank of gas after a year the Volt’s engine will run until the gas tank is empty in order to make sure that the gas in the tank does not get stale.

The average driver will not be able to replicate Oury’s results, but it is still exciting to see people push the limits of the Volt.
