2018 Mercedes-Benz S-Class S 450 L AMG Line Review

The luxury executive sedan market in Malaysia has always been a benchmark battlefield for brand technology and comfortable experiences. As a core player in this segment, the 2018 Mercedes-Benz S-Class S 450 L AMG Line, with its AMG sports package enhanced exterior, luxurious rear-seat configurations, and 3.0L V6 powertrain as key selling points, appeals to users who pursue both a premium business atmosphere and driving quality. This test drive will thoroughly break down this car from static details to dynamic performance to see if it lives up to the positioning of a "flagship executive sedan."

From the exterior, the S 450 L AMG Line is immediately distinguishable from the standard version of the S-Class. The front features a large, star-pattern grille paired with AMG-specific front bumpers, while the design of the side air intakes appears more aggressive. The smooth and elongated side profile, combined with 20-inch multi-spoke wheels and the 245/40 R20 (front) and 275/35 R20 (rear) wide tires, enhances its sporty feel. At the rear, the AMG rear spoiler and dual exhaust pipes with chrome plating maintain the dignified look of an executive sedan while adding a touch of vitality. All variants come standard with LED headlights featuring automatic activation and cornering assist functions, which enhance practical daily usability and offer high recognition on the road.

Opening the car door, the luxurious interior immediately comes into view. The dashboard is wrapped extensively in soft-touch leather, complemented by metallic trim and wood-grain panels, providing a tactile feel of refinement in every reachable area. A 12.3-inch fully digital instrument cluster is integrated with a 12.3-inch touchscreen infotainment display, offering smooth interface performance and crystal-clear visuals that meet flagship vehicle standards. The driver's seat is equipped with 12-way electric adjustment and memory function, making it easy to find a comfortable sitting position. The rear seats are the highlight of this vehicle — not only do they support electric adjustment, but they also feature massage and memory functions, which can effectively alleviate fatigue during long journeys when using the massage feature. Standard features include a 360-degree panoramic camera, automatic parking, keyless entry/start, and dual-zone front and independent rear air conditioning systems to accommodate the needs of all passengers. Additionally, the 220V power outlet in the rear supports the use of laptops and other devices, offering further convenience for rear passengers.

In terms of space, the car's 5246mm length and 3165mm wheelbase create a spacious interior. Passengers with a height of 175cm sitting in the rear have more than two fistfuls of legroom and an extra fist of headroom, eliminating any sense of confinement. The trunk offers a capacity of 530 liters, which is sufficient for holding several suitcases or briefcases required for daily use, adequately meeting storage needs. The rear central armrest is equipped with control buttons, allowing direct adjustment of seats, air conditioning, and multimedia settings, showing thoughtful attention to detail.

For the powertrain, this car is equipped with a 3.0L V6 naturally aspirated engine that delivers a maximum horsepower of 372PS, and peak torque is achieved at just 1800rpm. It is paired with a 9-speed automatic transmission. The power response during start-up is very linear, allowing for smooth acceleration with light pedal application. Mid to high-end acceleration is confident, and during overtaking, pressing the accelerator deeply results in quick gear shifts and a notable thrust sensation. The officially rated 0-100 km/h acceleration time is 5.4 seconds, which is outstanding for an executive sedan weighing nearly 2 tons. There are three driving modes available: Eco, Comfort, and Sport. Switching to Sport mode increases throttle sensitivity and makes the shifting logic more aggressive, satisfying occasional driving enthusiasm.

The handling and chassis performance are also commendable. The steering wheel is precise with minimal play, lightweight at low speeds, and stable at high speeds, giving the driver great confidence. The chassis adopts a multi-link independent suspension, tuned for comfort without losing resilience—when going over speed bumps or bumpy roads, the suspension filters out most vibrations, and the body doesn't jolt significantly; when cornering, the suspension provides good support and controls body roll well, balancing comfort and handling. The daily driving fuel consumption is approximately 10L/100km (urban driving conditions), and it can drop below 8L on highways. For a car with a 3.0L engine, this fuel consumption is considered normal.

In terms of driving comfort, the Burmester 13-speaker sound system delivers excellent audio quality. The Sound Plus feature further enhances the sound effect. With the windows closed, cabin noise control is well-executed, with tire noise and wind noise being barely noticeable. The seats have soft padding and sufficient support, ensuring long-distance rides are not tiring. Additionally, the engine start-stop technology engages smoothly without causing noticeable jolts.

To summarize, the core advantages of the 2018 Mercedes-Benz S-Class S 450 L AMG Line are quite prominent: the AMG Line package enhances the exterior with a balance of sportiness and elegance. The luxurious rear seat features (such as the electric massage seats and independent controls) stand out among competitors in the same class. Its performance and handling cater well to driving needs. Compared to competitors like the BMW 7 Series or the Audi A8L, its rear seat comfort features are superior, and the luxurious ambiance is more refined.

This car is suitable for two types of users: first, business professionals who need to frequently entertain clients—the luxurious rear seat features provide an excellent experience for clients; second, families who value quality of life. The spacious interior and comfortable driving experience can meet the travel needs of the whole family.

Overall, the 2018 Mercedes-Benz S-Class S 450 L AMG Line is a "well-rounded" luxury executive sedan. Whether for business purposes or everyday family use, it performs exceptionally well and is a worthy choice in the luxury car market.
