完全redesigned with advanced technology and iconic style, the all-new 2021 Escalade is now arriving at Cadillac dealerships. (Fig. 1) With innovative features like a curved Organic Light Emitting Diode (OLED) instrument display, an AKG automotive audio system and the latest Super Cruise driver assistance system, the 2021 Escalade adds a new dimension to the full-size luxury SUV market. In addition to its extensive technology, the Escalade delivers improved driving dynamics and significantly greater passenger and cargo capabilities.

Sleek Styling
The 2021 Escalade maintains Cadillac’s signature vertical lighting element, but the new interpretation adds a sleek, horizontal headlamp. The tall, vertical, rear light signature continues but adds deep three-dimensional layers and finishes with detailed etching. Twenty-two-inch wheels are standard and strengthen Escalade’s bold appearance.
A Sport trim, offered for the first time, is set with a black mesh grille and black trim across the exterior. Luxury and Premium Luxury models showcase a bright Galvano finish, while Platinum models top the range with unique interior and exterior details. (Fig. 2)

eScalade继续在短轴和长轴的版本中提供。Escalade有一个211.9英寸的轴距，高达94.2立方英尺的货物空间，而Escalade ESV有一个226.9英寸的轴距，高达129.9立方英尺的货物空间。两种型号都提供全新的3.0L Duramax Turbo-Diesel或更新的6.2L V8发动机，带有动态燃料管理。
2021 Escalade采用通用汽车智能平台（VIP）设计和设计。高级数据通信平台可实现额外的系统容量和响应性，增加空中车辆软件更新能力和增强的网络安全。
Gas and Diesel Engine Choices
Escalade提供新的3.0L Duramax柴油内联6缸发动机（RPO LM2）或气体动力Gen 5 6.2L V8发动机（RPO L87）。两个引擎都具有停止/启动系统，以提高效率。
3.0L涡轮增压柴油发动机是气缸架策略（CSS）的一部分发动机，可减少摩擦，重量和废气排放，同时还提供超越他们取代的发动机的燃料经济性。涡轮增压器系统包括电子操作的废气门阀，并提供良好的低端扭矩以及高端性能。柴油发动机生产277马力和460磅。速率。扭矩。
The 3.0L diesel engine incorporates solenoid-type fuel injectors that are controlled by the Engine Control Module (ECM). (Fig. 3) The solenoid-type fuel injectors require a special tool for removing the injectors from their bore. However, in extreme cases, use a slide hammer with an M6 x 1.0 thread installed in place of the fuel return banjo bolt. In such cases, ensure all force is directed straight upwards from the fuel injector.
图3.
The solenoid injectors also require a new injector bore and sleeve-cleaning kit for the engine injector bores. The cleaning kit removes carbon deposits from the fuel injector sleeve bore, which is very helpful during a fuel injector replacement.
The high pressure fuel pump is a mechanical pump attached on the driver’s side of the engine block and is driven by the timing chain. The high pressure pump on vehicle service is similar to other small diesel engines. Access to the pump-driven sprocket can be obtained by removing the fuel pump access cover. Use the special tools to retain engine timing while removing the high pressure fuel pump.
When replacing just the pump, the timing is retained by the tools. If the high pressure fuel injection pump-driven sprocket is removed from the engine, then the timing adjustment must be performed.
The Gen 5 gasoline V8 engine generates 420 horsepower and 460 lb.-ft. of torque. The Dynamic Fuel Management system is an Active Fuel Management™ technology that can deactivate any combination of cylinder valves of the engine, combining millisecond accurate torque control with cylinder deactivation to optimize fuel consumption. (Fig. 4)
图4.
The Dynamic Fuel Management solenoid requires a tool to remove the valve lifter oil solenoid valves. The magnetic tool helps gain leverage to remove the valve lifter oil solenoids from the block. Once installed on top of the solenoid, place a hand over the remover and solenoid with a finger under the solenoid. Twist while pulling up on the tool and the solenoid.
The stop/start system on both gas and diesel engines automatically shuts down the engine in appropriate conditions, such as when stopped at a traffic light. To support the increased number of engine starts, a high performance electric starter motor with a stronger pinion engagement mechanism to reduce noise levels replaces the conventional starter motor.
Along with the upgraded starter motor, advanced battery technology is required to ensure the vehicle’s battery can handle the frequent charge and discharge cycles common with stop/start operation. There is a battery sensor module connected to the battery, which continually monitors the battery charge and health state. The ECM uses this information from the battery sensor module to determine if the battery charge and health are sufficient for a stop/start condition. The stop/start system can be disabled using the Auto Stop button on the center console. (Fig. 5) The system turns on each time the vehicle is started.

10速自动变速器
Both engines are mounted to the Hydra-Matic 10L80 10-speed automatic transmission (RPO MQC). The heavy-duty transmission features a case with an integral bell housing and the unique off-axis variable vane-type pump drive design allows for very low mounting.
The four planetary gear sets provide ten forward gear ratios and Reverse. Changing gear ratios is fully automatic and is accomplished through the Transmission Control Module (TCM). The TCM receives and monitors various electronic sensor inputs and uses this information to shift the transmission using output controls. The TCM is mounted at the left front of the vehicle, behind the underhood fuse block.
使用电子传输范围选择器（ETRS）系统控制传输，该系统取代传统的柱安装的移位器。（图6）ETRS系统是逐线系统，选择器控制和传输之间没有物理链路。

The Escalade is offered in rear-wheel drive or all-wheel drive models. Single-speed and 2-speed transfer cases are available on all-wheel drive models: the 3015 1-speed automatic active transfer case (RPO NPO) and the 3025 2-speed automatic active transfer case (RPO NQH). Shift controls are located on the left side of the instrument panel. (Fig. 7)

Driving Dynamics
新的Escalade的驱动动力学通过新的独立后悬架以及可用的磁乘控制，空转自适应悬架和电子限量滑动差分（ELSD）。独立的后悬架允许每个后轮单独处理道路条件，以提高乘坐质量，转向响应性和整体驾驶员控制。此外，可用的磁骑控制使用传感器不断地“读取”道路，并几乎立即改变冲击的阻尼率，以减少垂直体运动，体辊和振动。
可用的空气骑自适应悬架在所有四个轮子中连续提供自动负载平整和骑行高度调节。在公路驾驶中，系统自动降低乘坐高度以改善空气动力学;驾驶员可选择的设置降低了悬架2英寸（51毫米），以帮助乘客入口并在车辆停放时退出。退出电平开关是否处于越野模式或牵引/运输模式时，车辆将不会降低。在越野时，身体也可以提高额外的地面间隙。仪器集群上显示空中自适应悬架设置。（图8）

To deliver additional traction and power engagement to the rear wheels, the available electronic limited-slip differential (RPO G96) uses infinitely variable clutch engagement to provide torque to the wheel with the most traction, including when cornering and in wet weather conditions. The locking torque causes a multiplication of wheel torque, which can be used to improve traction and/or vehicle dynamics. The differential lock motor actuates a multidisc friction clutch via a reduction gear set. The differential lock motor is used to close and open the clutch.
安全系统
The safety systems offered on the 2021 Escalade include various technologies that use radar, camera, and ultrasonic driving assistance. The systems are a comprehensive feature set designed to help a driver avoid collisions or reduce crash damage while driving, backing up, and parking.
Some of the standard or available safety technologies include:
- Forward Collision Alert
- Lane Keep Assist with Lane Departure Warning
- 自动紧急制动
- Front and Rear Park Assist
- Pedestrian Impact Detection
- Lane Change Alert with Side Blind Zone Alert
- 后交通警戒
- Safety Alert Seat
Trailering Package
拖欠的集成包提供最多9次摄像头视图，以支持更轻松的拖车挂钩和拖车监控。该包装还包括集成的拖车制动器控制器和拖车型材，提供拖车型材，轮胎压力和温度监测以及扩展侧盲区域警报。
OLED显示
在攀登是产业界首次弯曲OLED display, which offers more than 38 inches of total diagonal display area with twice the pixel density of a 4K television. (Fig. 9) The technology delivers bold imagery, perfect blacks and the largest color range of any automotive display in production today.
图9.
The system includes three screens: a 7.2-inch-diagonal touch control panel on the left side of the instrument panel, a 14.2-inch-diagonal instrument cluster display behind the steering wheel, and a 16.9-inch-diagonal Infotainment screen to the driver’s right. The OLED is paper-thin, and its curvature positions the displays for optimal visibility. (Fig. 10) The vivid color and visual quality of OLED technology eliminates the need for the common “hood” shrouding of many typical in-vehicle screens, creating a brighter and less cluttered environment.

AKG Audio Technology
在录音室和现场场地领先的音乐家使用的麦克风和耳机的全球知名，AKG在2021年的Escalade中首次将其音频技术带到汽车行业。
Escalade采用标准的AKG Studio系统，带有19个扬声器和一个大型封闭式低音炮，由14通道放大器提供供电。可用的AKG Studio参考系统有36个扬声器，由三种放大器提供动力，可提供28个通道，提供专业的工作室聆听体验。（图11）

Rear Seat Media
新的后座介质系统具有一对具有导航的12.6英寸对角线独立的触摸显示器，以及通过HDMI和USB输入玩游戏，音乐和视频的流媒体功能。（图12）屏幕也可以镜像Android智能手机。此外，后乘客可以将导航目的地建议发送到前导航屏幕。
图12.
系统附带的红外耳机使用AAA电池（提供），并自动连接到后座介质屏幕。耳机接收来自位于乘客侧（右）座椅靠背屏幕顶部的红外发射器的音频信号。要打开红外耳机，请按下位于耳机耳垫右侧的电源按钮。如果来自系统的红外信号丢失，则红外耳机在大约四分钟后自动关闭，例如后座介质系统关闭或信号超出范围。不使用时关闭耳机以保留电池寿命。
后座介质还通过每个屏幕通过蓝牙支持最多九个耳机的连接。如果客户希望使用自己的蓝牙耳机，可以通过后排座椅介质屏幕配对系统。
Soft-Close Doors
可用的软关闭门特征使用电动机将每个门拉到其初级位置后，在其二级闩锁位置关闭后，消除了硬门猛击。
PDI Special Instructions
在预付款检查期间，请检查以下特殊项目：
