All-New Cadillac CT5 Debuts with Style, Performance and Technology

作为凯迪拉克阵容中最新的豪华轿车，全新的2020年CT5曾设计具有多种性能和技术特征，并以时尚的重点概况包裹在凯迪拉克屡获殊荣的遗产上。（图1）具有后轮驱动或全轮驱动，CT5基于全球alpha车辆架构。

The CT5 is equipped with an all-new vehicle electronic system — the Next Generation Digital Vehicle Platform — capable of managing up to 4.5 terabytes of data processing power per hour. It provides more rapid communications within the vehicle itself and to outside sources due to Ethernet connections of 100Mbps, 1Gbps and 10Gbps.

Powertrain Features

在发布时，型号范围将包括豪华，高级奢侈品（图2）和运动型号。2.0L双涡旋涡轮增压器4-缸发动机（RPO LSY）是标准的，并产生估计的237马力和258磅。扭矩。

Later in the model year, the available 3.0L twin-turbo V6 engine (RPO LGY), which produces 360 horsepower and 405 lb.-ft. of torque, will be offered on Premium Luxury and V-Series models.

The turbocharged 2.0L DOHC, VVT 4-cylinder engine uses a twin-scroll turbocharger to help reduce turbo lag, with Active Fuel Management (AFM), Spark Ignited Direct Injection (SIDI) and Engine Stop/Start technology helping to improve fuel economy. (Fig. 3)

2.0L 4缸发动机具有滑动凸轮系统（SCS），使发动机控制模块（ECM）能够在发动机运行时更换进气和排气凸轮轴的凸轮轴升降轮廓。SCS使用四个进气凸轮轴轮廓致动器和两个排气凸轮轴轮廓致动器，其响应于来自ECM的电气命令轴向在凸轮轴上轴向改变凸轮轴升降轮廓套筒。每个凸轮轴具有两个具有不同高度凸轮凸起的型材套管，每个凸轮轴在每个套筒下具有棘爪球和弹簧，有助于将轮廓套筒保持在位置。

The SCS profile actuator solenoids push out an actuator guide pin into the shifting groove machined into the Camshaft Lift Profile Sleeve. When the guide pin engages the sleeve, it causes it to shift axially on the camshaft, causing unique-sized cam lobes to be placed over the intake and exhaust valves and modify valve lift and duration.

The cylinder block of the 2.0L engine is constructed of aluminum alloy by high-pressure die casting with four cast-in-place iron cylinder liners arranged in-line.

Within the engine block structural extension is the oil pump and the balance shafts. The balance shafts are driven by the balance chain. The oil pump assembly is driven by the balancer shaft assembly. The oil pump, which has variable flow capability to optimize oil flow to engine components as needed, uses a circular vane arrangement and the actuation of an oil control valve assembly commanded by the ECM.

The 2.0L turbocharged engine requires dexos1^®批准 - Gen 2全合成SAE 0W-20粘度级发动机油。

The fuel system is an electronic returnless on-demand design. An electric purge pump is mounted on the engine, which is designed to help comply with the most stringent emissions regulations. The electric purge pump manages the purge of vapors from the fuel tank. Compared with a traditional solenoid valve to purge emissions, the electric purge pump provides greater control over the timing and amount of purge.

Both the 4-cylinder and V6 engines are paired to the Hydra-Matic^®10L80 10速度自动变速器（RPO MHS）。（图4）使用四个简单的行星齿轮，两个制动器离合器和四个旋转离合器产生十种速度比。所得到的轴传动架构使用压扁的变矩器，轴轴泵和四个近耦合齿轮集。

全轮驱动

The Borg Warner™ Model BW-4475 transfer case is a 1-speed active design. The transfer case allows vehicle speed-dependent flexible clutch preload torque levels for enhanced system performance. An on-demand torque-biasing friction clutch is tuned through software calibrations.

该系统通过车辆的CAN总线具有与车辆底盘控制系统集成的自己的控制模块。前轴和后轴之间的扭矩不固定，并且系统的能力在需要根据需要将高达100％的可用扭矩转移到前桥。

Driver Mode Control

The Driver Mode Control allows the driver to personalize the driving experience by selecting one of three pre-optimized selectable Drive Modes: Tour, Sport, Snow/Ice, and My Mode. (Fig. 5) My Mode enables the configuration of vehicle sub-systems, including steering, powertrain, braking, engine sound and other tuning. The modes are selected by pressing the Drive Mode button on the center console.

Chassis Features

Chassis and driving dynamics features on the new CT5 include a standard Bosch premium electric, rack-mounted power steering system, eBoost brakes, and ZF MVS passive dampers as well as Brembo brakes on Sport models. (Fig. 6)

Fig. 6

Depending on options, the following vehicle performance enhancement systems are provided:

• ABS
• Adaptive Cruise Control
• Bi-directional WSS
• Brake Drying/Cleaning
• Collision Imminent Braking
• 动态后方比例
• 电子稳定性控制
• Engine Drag Control
• Extended Hill Hold Start Assist
• 恐慌制动辅助
• 青少年模式支持
• Traction Control
• Trailer Sway Control

在具有发动机稳定性控制（ESC），停止/启动功能和自动变速器的车辆上需要传动系统的阻尼。它保持制动压力来抑制驱动器加速度扰动，因为发动机重新启动并保持制动压力延迟或防止车辆滚动。它用于驾驶员舒适性，也用于延长陡峭等级的车辆保持。

在CT5的所有四个角落都是奢侈品型号的18英寸合金轮子，而优质奢侈品和运动型号配有19英寸车轮。

信息娱乐系统

The 1080dp high-definition full-color 10-inch-diagonal touchscreen is mounted high within the instrument panel for visibility. (Fig. 7)

There are two available audio systems. The Premium Audio System consists of nine speakers located in the center of the instrument panel, in each door, and in the rear package shelf.

The Bose Performance Series System consists of 15 premium speakers located in the center of the instrument panel, in each A-pillar, in each door, and in the rear package shelf.

Both systems feature Engine Sound Enhancement (ESE) to accentuate natural powertrain and exhaust system sounds and deliver them to the cabin at the right levels during the correct times, such as during engine start or spirited acceleration. It uses the infotainment system microphones, tachometer input, software integrated into the Amplifier/Active Noise Cancellation Module, and the vehicle speakers to determine and generate the correct frequencies needed to modify the sound and play it back through the speakers. The engineering and science behind ESE are rooted in orders, or sound frequencies, that are generated by the engine. ESE amplifies certain orders to achieve the desired sounds. Adding more orders produces a richer, more complex and pleasing sound. Sound levels are based on engine speed as ESE activates at approximately 3,000 rpm when the engine is moving into its optimal power band and on accelerator pedal position.

安全特性

Depending on equipment, the CT5 offers an array of standard and available safety, driver awareness and driver assistance technologies.

驾驶员意识技术包括标准安全警报座椅（SAS）和可用的后置相机镜，具有变焦和倾斜调节。

驾驶员辅助技术可能包括:Adaptive Cruise Control, Automatic Emergency Braking (AEB), Forward Collision Alert (FCA), Front Pedestrian Braking (FPB), Lane Change Alert (LCA), Lane Departure Warning (LDW), Lane Keep Assist (LKA) and Side Blind Zone Alert (SBZA).

In addition, parking or backing assistance technologies may include: Automatic Parking Assist with Braking, Backing Warning System, Front Park Assist (FPA), Rear Cross Traffic Alert (RCTA), Rear Park Assist (RPA), Rear Vision Camera (RVC), Reverse Automatic Braking (RAB) and Surround Vision.

CT5还配备了八个安全气囊，以帮助保护居住者，并具有先进的传感技术，以帮助检测发生的碰撞的类型和严重程度，以确保安全气囊根据需要快速充气。（图8）感测系统包括在车辆前部的四个基于加速的传感器，并且在车辆的任一侧和前门内的两个压力基传感器。

Hands-Free Decklid

CT5 also features an available hands-free power-release decklid. The hands-free decklid uses a motion sensor with a Cadillac crest target projection that allows owners to activate the trunk release by kicking their foot under the left side of the rear bumper. (Fig. 9)

平板拖车

建议平板车运输车运输残疾人车辆。移动车辆时，变速器必须处于中性状态。如果车辆配有牵引眼睛，只能使用牵引眼将车辆从平坦的路面拉到平板车载体上。不要使用拖曳眼从雪，泥浆或沙子拉动车辆。
