Here we should add that VW might be a great automaker but it certainly has room for improvement in the area of selecting names for its vehicles. Another weirdly named VW vehicle is the Tiguan, a smaller crossover which is unlikely to be replaced. Cadillac ELR

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. Lexus IS Sedan

Toyota's Lexus IS compact sports sedan will make its debut on Tuesday morning with three models: the IS250, the IS350 and the IS 300h, a hybrid, which will be available in international market.

Lexus has provided details which include a description of the Lexus spindle grille frontal design that will suggest "aggressive elegance, a more powerful road presence and a stronger brand identity."

Hellwig said the IS, like many newly introduced luxury cars, will attempt to compete with the BMW 3 Series. He said Lexus "didn't do anything real dramatic. They went with a very evolutionary tact and tweaked a lot around the edges."
