Since the engine is Cadillac's first twin-turbo unit, engineers focused on making it refined and powerful. They specifically tackled turbo lag by developing and patenting a new air flow design that uses less heat-exchanger tubing. Cadillac says this helps to reduce air flow routing volume by more than 60 percent when compared to a conventional design that features a chassis-mounted heat exchanger.
As Richard Bartlett, Cadillac assistant chief engineer for the 3.6-liter engine, explained “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. This gives the driver a more immediate feeling of power on demand.”
All told, the engine produces 410 bhp (305 kW) and 369 lb-ft (500 Nm) of torque in the XTS VSport and 420 bhp (313 kW) and 430 lb-ft (583 Nm) of torque in the CTS VSport.
Both models go on sale this fall and CTS VSport will be priced from $59,995 while the XTS VSport will retail for $63,020.
