We covered the Cadillac Converj Concept when it first debuted 4 years ago at the 2009 Detroit Auto Show (NAIAS), then once again when Cadillac renamed it the ELR “Extended Range” Coupe and first officially announced its move into production. Well today at 2013 NAIAS the official production car was revealed, and very little has changed from the initial ELR offering. Dubbing it an EREV (Extended Range Electric Vehicle), the ELR takes GM’s lower segment Volt technology and gives it a thorough up-and-down rebuild, upgrading it from a base compact car into a luxury coach fitting the Cadillac logo. Special attention was of course paid to the car’s interior, which is swathed in rich contrast-stitched leather, finished off with satin chrome and wood trim or optional carbon fiber accents. The powertrain of the ELR is an all-electric T-shaped lithium-ion battery drive with zero emission, which is augmented by a turbocharged 1.4L petrol-fueled four-cylinder engine that kicks in seamlessly when the battery power dies and generates electricity. Like the Volt, the gas engine does not actually power the car, rather it keeps the battery charged so the ELR can run on electric power. Although only the first 35 miles can run on EV power alone — enough for the average daily US commute, mind you — the total range of the ELR is around 300 miles, a terrific distance which should temper any talk of “range anxiety”. Once you’re home, you can recharge the ELR via a 120V or 240V outlet, achieving a full charge in about four and a half hours through the stronger 240V outlet. The ELR is slated to hit Cadillac showrooms by the end of this year.
