by Mark Kane (Inside EVs) The first generation Chevrolet Volt engine runs on gasoline, but as it turns out it can run on ethanol blends up to E85, as well. The switch to E85 is simpler than one might think because GM left ready-to-go software installed and all you need to do is to change some settings. The report about turning a used 2013 Chevrolet Volt into an E85 drinker comes from an automotive engineer – John Brackett, who expects that 2016 (1.5 liters direct injection) could also be changed as well (to be confirmed in the future). “It took me about 2 minutes to change the software program and about 3 minutes to write to the vehicle using a device called the HP Tuners. And those are very affordable. Basically, if you knew somebody with one, it’d be $100 to re-flash your vehicle.”
