Recently, Mercedes-Benz launched the new SL63 S E Performance, which is a plug-in hybrid sports model, as the star model of the Mercedes-Benz family, SL was born in the 50s of the last century, after many generations of development. Now they have followed the trend and joined the hybrid ranks, and the plug-in hybrid version has reached an astonishing 1420Nm of torque, how can this be done?Let's break it down in detail.
amgInterconnectedActive suspension
AMG active suspension is also standard on the SL63 S AMG E Performance Edition, with semi-active roll stability control. The displacement damper can be adjusted during rebound and compression, while the semi-actively interconnected hydraulic elements replace the traditional stabilizer bar. This technology reduces body roll movements, the shock absorber chambers on all four wheels are hydraulically connected by pipes and control valves, and the connected suspension is a technology from high-end racing that allows the suspension to interact with each other and reach new levels of handling and comfort.
The interconnection of four shock absorbers means that the range of spring rate adjustment is larger, and when turning, the hydraulic system can also reduce camber loss, resulting in high camber stiffness, simply put, the vehicle steering is very accurate, pointing to where to hit, the weight problem of plug-in hybrid vehicles is also solved, and the control is flexible.
When driving in a straight line, the connected suspension is automatically unlocked, and the wheels are independent of each other, for example, the pothole on the left does not affect the tire on the right, maintaining ride comfort.
Front axleInternal combustion engine+ Rear axleMotors
The front axle is equipped with AMG's 40T V8 twin-turbo engine, combined with an electric drive unit on the rear axle. The electric drive unit integrates a 204 hp excitation synchronous motor, a 2-speed transmission and a mechanical rear axle limited-slip differential. The lightweight, high-performance battery is also located above the rear axle, and this compact design brings a number of advantages. The electric motor acts directly on the rear axle, reducing power loss.
The power of the rear axle motor can be transmitted to the front axle, and the power is transmitted through the 4MATIC+ mechanical system, in addition to the auxiliary power, the electric drive unit is arranged on the rear axle, which echoes the V8 of the front axle, and the front and rear counterweights are more reasonable, which reduces the counterweight problem of the front V8 model and reduces the cornering pusher.
The practicality of the 2024 Mercedes-Benz SL63 S AMG E Performance Edition
First acceleration
4.The combination of a 0-liter V8 twin-turbo engine and an AMG electric drive unit produces a combined power of 816 hp and a peak torque of 1420 Nm. The instantaneous torque of the motor compensates for the lack of torque of the turbocharged engine at low revs, and the acceleration time to 100 km/h is 2In 9 seconds, the vehicle can reach a speed of 317 km h.
In addition to the connected suspension and 2-speed gearbox, the SL63 also comes standard with rear-wheel active steering. Depending on the speed, the steering direction of the rear wheels automatically changes, and the front and rear are reversed within 100 km h, and the front and rear are the same for more than 100 km h, and the turning radius is reduced at low speeds, making driving more stable at high speeds.
Second, pure electric range
Inspired by Mercedes-Benz F1 hybrid racing cars, lithium-ion batteries are designed for sport cars with high power density and fast discharge capability. The capacity of the battery is 61 degree, the peak discharge power is 150 kW. As a sports car, the battery is designed to power up and drain power quickly, rather than for a long all-electric range, and the all-electric range of this new car is only 13 km, which is not common in plug-in hybrid models.
In terms of cooling, AMG has specially designed a direct cooling system for 400V batteries, where the coolant flows around 560 small batteries and cools them separately, so that the battery pack is always in the working temperature window of about 45 degrees, and it is not afraid of overheating when driving fiercely on the track.
Third ride
Although the SL is a sports convertible, since its birth, it has been characterized by a luxurious interior with a high-horsepower engine, **SL's interior is still exquisite, and the 2+2 seat layout increases practicality. AMG uses the seat's integrated headrest and seatback vents with three built-in massage programs. The upholstery of the seats can be freely selected, including Nappa leather in a variety of shades, as well as elegant Manufaktur Nappa leather and hand-quilting. If you want a more sporty vibe, you can choose a combination of Nappa leather + microcut fibre with red contrast stitching.
Fourth, personalization
The SL63 S AMG E Performance Edition not only has a unique appearance, but also has an active aerodynamics package that automatically extends the front lip at speeds above 80 km/h, creating a venturi effect and reducing lift on the front axle. Another active component is the retractable rear spoiler, which is seamlessly integrated into the trunk lid and changes position depending on the driving conditions. From 80 km h, the spoiler can be changed at five different angles to increase downforce and give the look even more personality.
Car Pick Detective Viewpoint:The SL63 S AMG E Performance Edition uses technologies from Formula 1 cars, such as connected suspension and battery cooling, to reach new levels of powerThe acceleration level of 9 seconds is not inferior to the current high-performance electric vehicles, but the pure electric range is poor, what do you think of Mercedes-Benz's plug-in hybrid technology?Welcome to discuss.
