If Equinox were fitted with a Volt or Bolt EV drivetrain what sort of range reduction could we expect? Well, some gas mileage figures from the latest Chevy 'New Roads' magazine might offer a clue: The Cruize Diesel is rated at 52 mpg. The same engine in the new Equinox is rated at 40 mpg, a 23% reduction. This is a pretty good number to use -the difference based on vehicle weight and drag- because in the EPA test all else IS equal. So an EquiVolt might achieve about 42 miles range and an EquiBolt, about 183 mi. Loaded to the roof with kids and vacation gear the range might not be so good, but nevertheless, would you buy one?
