Cadillac will be offering two new V6 engines in its CT6 large sedan, which is set to be showed off in New York later this month.

One of the engines will be a 3.6-liter V6 engine, with the other being a 3.0-liter twin turbo V6 engine. Both of the engines will feature new technologies, such as active fuel management and automatic stop-start, designed to result in far better fuel economy.

"Cadillac's elevation on the world stage is driven in great part by its advanced powertrain technology and the all-new 3.0L Twin Turbo powers past the traditional segment leaders with higher degrees of the performance and refinement their reputations were built on," said assistant chief engineer Rich Bartlett.

The engines will also make heavy use of aluminum in order to keep the weight of the engine down, essentially boosting fuel economy even more. General Motors promises not only better fuel economy, but also a quieter engine than its competition with more power and torque.

In fact, the direct-injected engine will generate around 400 hp, with Cadillac claiming that it will be the most power-dense engines of its kind.

Both of the new engines will be manufactured in General Motors' Romulus factor, in which General Motors recently invested a whopping $540 million to purchase the equipment necessary to build sophisticated and complex new parts for these engines.

"Cadillac is investing heavily into expanding our portfolio with eight new products by 2020," said David Leone, Cadillac Chief Engineer. "It will be in five of those segments for the first time, which require Cadillac to develop a much wider range of powertrain."

Cadillac will show off the new CT6 on March 31 at the New York International Auto Show.

Many suggest that the move is a good one for Cadillac, which has been suffering of late due to many feeling that it is a little past its time. While the luxury car company was once highly revered, many now see it as more dated. Introducing new technology into its line of new cars may likely help outgrow that dated feeling, causing a new generation of Cadillac-lovers to form.

In fact, the new engines are 99 percent new, with only two small parts from previous engines being used. This means that the engines were almost completely redesigned.

General Motors, Cadillac's parent company, made a number of announcements today, including one that introduced a number of new features for parents of teens who want to be able keep better track of their teen driver's driving habits.
