The EPA has now certified fuel-economy ratings for the 2014 Cadillac ELR, and it is now the luxury brand's most efficient car, by a wide margin.
The ELR offers fuel economy of its gas-electric drivetrain of 33 miles per gallon combined. More important to green-car shoppers will be its electric-only driving range of 37 miles, and its 82-MPGe fuel-efficiency rating when operated on electric power alone.
Those figures are roughly equal to the ones affirmed for the Chevy Volt, which pioneered the ELR's primarily series-hybrid drivetrain, though the ELR carries around about 200 pounds of additional weight despite two fewer doors. Charging times remain the same, at about 4.5 hours on a 240-volt connection or more than 7 hours on a 120-volt household outlet.
On a full tank of gas, the ELR has an operating range of 340 miles.
Cadillac’s CUE infotainment system has new layers of information to display the ELR's charging status and operational efficiency--and like the Volt, it can be monitored by remote via a smartphone app that also provides drivers with the ability to set charging times based on lower electricity rates, and to set up alerts for battery charge state.
Our initial drives in the ELR didn't provide the chance to measure our own fuel economy--and took place in the canyons around Malibu, where fuel efficiency takes a nose-dive. We'll report back as we have more real-world exposure to the ELR.
