The sleekly raked ELR is the Cadillac version of the Chevrolet Volt. Like the Volt, the ELR's plug-in electric/gasoline powertrain allows it to run on electricity alone for up to 37 miles before resorting to the 1.4-liter four-cylinder to extend the range up to 340 miles. Chrome, nicely-stitched leather, wood trim, and carbon fiber accents create a warm, luxurious interior, but visibility is wanting. A full suite of advanced safety alert systems, including forward-collision, blind-spot, and cross-traffic alert is available. The instrument panel features the CUE infotainment system, which we have found distracting and frustrating. It was discontinued after 2016.
