Cadillac's big sedan plan

The heavily camouflaged Cadillac luxury sedan — code-named LTS for now — has been spotted this year during testing near the GM proving grounds in Milford, MIch.

DETROIT -- A large, range-topping sedan Cadillac that will launch in 2015 is a prerequisite to competing against BMW, Mercedes-Benz, Audi and Lexus, said General Motors global product chief Mark Reuss.

"If we're a serious luxury carmaker, it's really important to us," Reuss said last week. "This is a car that Cadillac needs, that will define its brand in terms of innovation and excellence. That's the mission."

Cadillac's chief engineer, Dave Leone, told Bloomberg this month that the rear-wheel-drive sedan would arrive sometime in late 2015. It was the first time a GM official has publicly given a time frame for the long-rumored sedan, code-named LTS for now.

Reuss declined to discuss specifics but said Cadillac's entry into the large luxury sedan segment "has got to be a symbol of excellence."

The sedan, which has been spotted testing at GM's proving grounds in Milford, Mich., is expected to compete against the Mercedes-Benz S class, BMW 7 series and Audi A8.
