2014 Cadillac CTS sedan to get new 420-hp twin-turbo V6 engine


The last time we’ve heard of a twin-turbocharged V6 engine was when it rolled out its Camaro prototype at the SEMA Show and later at Jay Leno’s Garage. We thought that the twin-turbocharged V6 engine was just for show, however, GM has been quietly working on this prototype since its debut. Now the company has confirmed that the next 2014 Cadillac CTS sedan will get this unique engine.

According to the company, the new 2014 Cadillac CTS sedan will debut at the New York Auto Show next week, and it will carry a twin-turbocharged V6 engine producing about 420 horsepower and 430 pound-feet of torque, which comparable to a V8 engine. The new engine is code named as the LF3, and it will be coupled with a new eight-speed automatic transmission on the Caddy. At a strip, the new twin-turbo CTS sedan can blast from 0-60 mph in just 4.6 seconds. Not too shabby for a sedan.

Obviously, the goal of a twin-turbocharged V6 engine and  an 8-gear transmission is to provide more fuel efficiency, rather than using a big V8 engine. But as we all know, turbocharging an engine does require extra fuel needed to pump in to compensate the forced air. So, the fuel injection process has be managed properly to see some real gain in fuel efficiency. According to General Motors, the new sedan will return 17 miles per gallon in the city and 25 mpg on the highway, which are similar to the current base model sedan.

The 2014 Cadillac CTS sedan with a twin-turbo V6 engine will be available this fall, and it will also come with a carry over 3.6-liter V6 engine and a 2.0-liter turbocharged four-cylinder engine from the Cadillac ATS sedan. More news to come next week, so stay tuned.
