For the 2018 model year, the Buick Regal is all new and features two new body styles — Sportback and TourX (Fig. 1) — and an aggressive top-of-the-line GS model. The Sportback is available in Front-wheel drive (FWD) and All-wheel drive (AWD) while the rugged TourX (U.S. only) and GS are available only as AWD models.

Three Unique Models
The Sportback (Fig. 2) is a five-door hatchback with a long, sloping backlight, which provides the ability to accommodate more cargo while offering the utility of a traditional hatchback or wagon. The Sportback rides on a longer wheelbase and weighs around 200 pounds (91 kg) less than its predecessor. The FWD Sportback has a 2.0L turbocharged 4-cylinder engine (RPO LTG), with 250 horsepower and 260 lb.-ft. of torque, which is mated to a 9T50 9-speed automatic transmission (RPO M3D).

The TourX (Fig. 3) is an AWD crossover with the driving dynamics of a car and the versatility of an SUV with seating for up to 5 passengers. The TourX rides higher than the Sportback for greater ground clearance and capability. It has a rugged exterior appearance with standard roof rails.

The hands-free power liftgate with a Buick tri-shield logo lamp that illuminates the ground beneath the sensor (Fig. 4) is available on upper trim levels. The power liftgate control knob for setting the liftgate height mode is located on the driver’s door.

As AWD models, the Sportback and TourX feature a 2.0L turbocharged four-cylinder engine (RPO LTG) that generates 250 horsepower and 295 lb.-ft. of torque. Both models have a standard Aisin AF50 8-speed automatic transmission (RPO MRC).
The Regal GS (Fig. 5) is distinguished by sportier front and rear fascias, side skirts and a rear spoiler. The GS is powered by a new 3.6L V6 engine (RPO LGX) that produces 310 horsepower and 282 lb.-ft. of torque, delivered to a more refined 9T60 9-speed automatic transmission (RPO M3T). It features Intelligent AWD, a second-generation Continuous Damping Control (CDC) suspension that is capable of 500 adjustments per second, and Interactive Drive Control so the suspension and other settings can be adjusted using three programmable drive modes. The AGR-certified (Aktion Gesunder Rücken, or Campaign for Healthier Backs) performance seats offer heating, cooling and massaging functions with adjustable seat and seat-back bolsters as well as thigh support.

发动机
由于其双滚动设计，2.0L涡轮增压4缸发动机产生高达20磅（138千瓦）的提升，有助于优化来自发动机的可用电源。涡轮机上的每个涡旋盘由单独的排气通道送入一个来自汽缸的一个和四个，另一个来自汽缸两个和三个。侧面直接燃料喷射冷却进气过程，其允许发动机在更高的升压和比较较高的压缩（9.5：1）比比传统的涡轮发动机上安全地操作。
涡轮增压器进气系统由空对空气电荷空气冷却系统支撑，该气体冷却空气冷却系统使用通过热交换器吸入的新鲜空气，以降低在输送到发动机燃烧系统之前离开涡轮压缩机的热压缩空气的温度。电荷空气冷却器通过柔性管道连接到涡轮增压器和节流阀，该柔性管道需要使用特殊的高扭矩紧固夹具。
该发动机还具有两级可变位移油泵，可根据发动机对油的需求改变其容量。使用dexos1.®SAE 5W-30 viscosity grade engine oil.
The new 3.6L V6 engine represents the fourth generation of GM’s DOHC V6 engine family. It incorporates Active Fuel Management (AFM) and advanced Stop/Start engine technology.
AFM系统由凸轮轴，阀门，开关滚筒手指追随者（也称为阀门开关摇臂），双馈液睫毛调节器和油控制阀（也称为阀摇臂油控制阀）。通过AFM系统，取决于发动机转速，油控制阀将油直接引导到双馈液压调节器解锁开关滚筒手指粉丝，这会产生零升力，并且不允许阀门在圆柱体上打开两个和五个。随着AFM系统关闭，开关滚筒手指粉丝随着正常的摇臂和AFM不活跃。
The engine also uses a dual-pressure control and variable-displacement vane pump that enhances efficiency by optimizing oil pressure. The oil pump is located beneath the cylinder block inside the oil pan. Use dexos1® SAE 5W-30 viscosity grade engine oil.
两个引擎都采用停止/启动技术（RPO KL9），以提高城市驾驶的燃油效率。当车辆进入停止时，发动机自动关闭，例如运行条件，例如在交通灯处。为了支持增加的发动机数量开始，启动电机用高性能电动机和具有降低的噪声水平的更强的小齿轮接合机构升级。还有一个连接到电池的智能电池传感器，不断监控电池充电和健康状态。
活动双离合器AWD系统
双离合器传递en AWD系统与活跃hanced handling and stability by preemptively and electronically splitting the torque as needed between the rear wheels using twin clutches to provide added traction, stability and control versus a 50/50 split in a single clutch system.
具有主动扭矩偏压的有源双离合器系统具有增加的所有驾驶条件的稳定性的能力，包括当车辆的一侧在滑动的表面上时，另一侧具有更多牵引力。
别克quiettuning™
QuietTuning™ is a Buick-pioneered process to reduce, block and absorb noise and vibration to create a quiet cabin. QuietTuning™ features enhancements with ultradissipative materials and Active Noise Cancellation (standard on V6 and AWD models). Active Noise Cancellation uses an amplifier and a computer with three or four strategically-placed microphones (three in GS and Sportback AWD models and four in the TourX) in the vehicle headliner. The system detects undesirable frequencies from the engine and then directs undistinguishable counteracting sound waves through the speakers to cancel out the noise.
此外，Regal还采用了第一个推动的轮胎应用，旨在在路上保持安静。大陆Contiliteil 235 / 50R18，P245 / 45R18或245 / 40R19轮胎在轮胎内具有安静的泡沫。（图6）

Infotainment Systems
The infotainment technology in the Regal models includes a new, frameless 7-inch (178 mm) color touchscreen system (RPO IOB), or a frameless 8-inch (203 mm) color touchscreen system with enhanced connectivity (RPO IO5) and available embedded navigation (RPO IO6). (Fig. 7)
