Now take some of that same gravitas, and plug it in, and you get some of the essence behind the all-new 2014 Cadillac ELR.
The ELR is built on the same platform that underpins the Chevrolet Volt, with essentially the same extended-range electric-vehicle (EREV) propulsion system—including the 16.5-kWh battery pack, and the same 1.4-liter four-cylinder engine under the hood. You’ll get about 35 miles of driving on electric power alone before the gasoline engine fires up seamlessly to provide range-extending power for the motor system (as well as traction-motor support at higher speeds).
But thanks to revised software and calibration, as well as a new Sport driving mode, GM has managed to eke more performance from the electric system: The electric motor system delivers a bit more: 207 hp (154 kW), with 295 foot-pounds of instant torque, and 0-60 times are expected to be eight seconds, or possibly even a bit better than that.
Doing more with the Volt
“We’ve found ways to exercise the battery more, and done more with motor control,” said chief engineer Chris Thomason, who confirmed that the ELR does use a wider depth of charge for the battery pack compared to that of the Volt.
Powertrain and underbody aside, according to the team behind the ELR, that’s where the similarities end. Designers managed to preserve most of the 2009 Converj Concept’s sheetmetal and rakish proportions—with top-notch details such as jewel-like all-LED headlamps and taillamps, as well as a flush-look version of the Cadillac eggcrate grille, with active grille shutters beneath. And in order to get the right ride quality, refinement, and low rolling resistance out of huge 245/40R20 tires—to keep the proportions on the outside—Cadillac looked to Bridgestone to develop a special OEM version of its Potenza line.
