High-Power Engine Developed Entirely In-House by AMG, First-Ever All-Wheel Drive in SL History
The SL, an abbreviation of "Super" and "Light," was born in 1952 as a racing sports car capable of driving on public roads.
Among these, the "300 SL" (W198), based on the "300 SL" (W194) and unveiled in 1954, achieved a brilliant track record worldwide, including a one-two finish in the 24 Hours of Le Mans.
Celebrating 70 years since the birth of the "300 SL," the new SL has been born as a model developed entirely in-house by Mercedes-AMG.
While paying homage to the design of the "300 SL," it features a luxurious interior space.
Mercedes-AMG SL 63 4MATIC+
The high-performance "SL 63 4MATIC+" model, newly introduced to Japan, is equipped with AMG's "M177" 4.0-liter V8 twin-turbo engine, which produces a maximum output of 430 kW (585 hp) and a peak torque of 800 Nm.
Paired with a specially tuned 9-speed AMG SPEEDSHIFT MCT transmission, it achieves 0-100 km/h acceleration in 3.6 seconds and a top speed of 315 km/h.

This high-power engine is driven by the "4MATIC+" all-wheel-drive system with continuously variable torque distribution, adopted for the first time in the SL's history.
"4MATIC+" combines the advantages of different drive systems. By continuously varying the front-to-rear torque distribution, it not only ensures optimal traction up to the physical limits but also contributes to high driving stability and safety under all driving conditions, including dry, wet, and snow.
Furthermore, the continuous variable torque distribution function calculates the optimal torque split based on driving conditions and the driver's input, allowing for seamless transitions between traction-focused all-wheel drive and pure rear-wheel drive.

The suspension features a multi-link setup with all five links housed inside the wheel, a first for a mass-produced Mercedes-AMG vehicle.
By independently controlling the wheel and suspension functions, it achieves high lateral acceleration while minimizing the influence of driving force on the steering system, significantly enhancing dynamic performance.
It is also equipped with the newly developed AMG ACTIVE RIDE CONTROL suspension. Utilizing an active hydraulic system, it can instantly correct body roll, thereby improving comfort.

Another notable feature, standard for the first time on an SL, is the rear-axle steering. This system steers the rear wheels in the same or opposite direction as the front wheels, depending on vehicle speed.
Within the range of characteristics tuned for the "SL 63 4MATIC+," the rear wheels are electronically controlled. Below 100 km/h, the rear wheels steer in the opposite direction to the front wheels.
This effectively shortens the wheelbase, requiring less steering input from the driver when entering corners.

Conversely, above 100 km/h, the rear wheels steer in the same direction as the front wheels, effectively lengthening the wheelbase and enhancing steering stability and cornering performance.
The exterior and interior design befitting the SL's top-tier model have been realized, creating a sportier aesthetic.
In conjunction with the introduction of the "SL 63 4MATIC+" to Japan, the "SL 43," equipped with a 2-liter inline 4-cylinder turbo engine, also sees equipment changes.

A newly designed bonnet emblem has been adopted, and the Memory Parking Assist function has been added as standard equipment.
This function allows the vehicle to memorize a route between two designated points, enabling it to travel along the route and park itself.
The "SL 63 4MATIC+" is available only with left-hand drive and is priced at 28.9 million yen. The "SL 43" is priced at 17 million yen.
