凯迪拉克将对CT6进行大幅动力系统升级，新款V-Sport版本将成为该车首款搭载4.2升V8双涡轮直喷引擎的车型，该引擎功率达到410千瓦/550马力，扭矩850牛米。另外还有一款373千瓦/500马力的版本。为降低引擎重量，新引擎采用了铝制气缸体和活塞，而锻造钢制曲轴和活塞将可确保涡轮压力达到1.38巴。涡轮采用水空中冷为空气降温，可以获得更多氧气以便最大限度提升动力输出。车厂预计此项设计将使进气温度降低超过摄氏74度。CT6V-Sport可搭配十速自动变速箱和限滑后差速器以提升车辆牵引力。电磁减震可提升动态操控性能，搭配的19英寸Brembo刹车盘可以让这辆高性能轿车获得更强制动力。

 

2019 Cadillac CT6 V-Sport Gets New 550-HP Biturbo V8

Cadillac will give the CT6 a major power upgrade because the new V-Sport model will be the first vehicle to get a direct-injected 4.2-liter biturbo V8 that will pump out 550 horsepower (410 kilowatts) and 627 pound-feet (850 Newton-meters) of torque in the top output. There will also be a 500-hp (373 kW) version.

 

To save weight, the new engine uses an aluminum block and pistons. A forged steel crankshaft and pistons make sure that the powerplant can handle the turbo's making up to 20 pounds (1.38 bar) of boost. The turbos feature a water-to-air intercooler for cooling the boosted air, which results in more oxygen in a given volume to maximize power output. Cadillac estimates that the system reduces the air charge temperature by more than 130 degrees Fahrenheit (74 degrees Celsius).

 

The CT6 V-Sport will pair the new engine with a 10-speed automatic gearbox, and a limited-slip rear differential will help with traction. Magnetic Ride Control dampers help sharpen the handling, and a set of 19-inch Brembo brakes handle stopping the performance sedan.
