凯迪拉克近日在纽约车展发布了新的CT6V-Sport高性能版本。新车采用金属网格格栅,LED大灯,窗框周边抛光黑色装饰,车身侧面可见20英寸轮圈,当然,该轮圈只搭配夏季轮胎。这款车搭载一台4.2升V8直喷双涡轮增压引擎,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确保涡轮输送的压力达到20磅(1.38巴)。涡轮采用的水气中冷可以对经过加压的空气降温,从而增加氧气量,产生更大功率。凯迪拉克预计,该系统可将空气交换温度降低74摄氏度。CT6V-Sport可搭配新的十速自动变速箱,限滑后差速器以提升牵引力。电磁减震可进一步提升操控性,而19英寸Brembo刹车盘则可提供更强劲的制动力。
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.
The V-Sport also features a mesh grille and comes with LED headlights. Gloss black trim surrounds the windows, and the model rides on 20-inch wheels, which are available with summer-only tires.
