Cadillac Explains New Twin-Turbo V6 Engine

According to the Michigan-based manufacturer, Cadillac engineers designed the new unit focusing on improving the engine’s “key limitation” - the turbo lag. And they’ve managed to “kick the turbo lag to the curb” by using a innovative combination of smaller turbochargers, a top-mounted throttle body, and shorter air pathways.

“By creating a very short path from the turbos to the throttle body, the compressors are able to draw air directly from the inlet box and send pressurized air through the intercooler immediately,” said Richard Bartlett, Cadillac assistant chief engineer for the engine. “This gives the driver a more immediate feeling of power on demand.”

As a reminder, the twin-turbo 3.6-liter V6 mill will deliver 420 bhp and 430 lb-ft of torque in the CTS VSport and 410 bhp and 369 lb-ft of torque in the XTS VSport.
