The Cadillac ELR, a luxury coupe based on extended range electric technology, will be unveiled at the auto show. "It uses the technology of the Volt in a two-door Cadillac coupe," Hellwig said.
Production is scheduled to begin in late 2013 at GM's Detroit Hamtramck plant, which is also home to the Volt. The ELR is extended to be unveiled on Tuesday.
"The ELR will be in a class by itself, further proof of our commitment to electric vehicles and advanced technology," Mark Reuss, GM North America president, said in a prepared statement.
