The SL’s long history marked technological milestones in the automotive world, while the 1954 300 SL Gullwing was the world’s first direct fuel injection sports car. Newer cars like the Mercedes-AMG SL 43 have smaller engines. and equipped with an electric turbocharger With this technology, the SL 43 appears to be the smallest of the new models. The high-powered 2.0-litre engine combines the driving performance of an AMG car with the luxury and comfort of an electric turbocharger. It’s an interesting example of a transfer. Between Formula 1 technology and real-world vehicle development
The M139 in-line four-cylinder petrol engine offers experience in the form of Mercedes-AMG High Performance Powertrains. New drivetrain technology also increases agility. And it makes driving with an open top more fun. AMG engineers have improved the performance of the compact drivetrain. for advancement by pursuing the goal of reducing pollution with a look to the future That will have to change to an electric propulsion system. Innovative components of the internal combustion engine, such as the electric exhaust turbocharger, help the SL 43 achieve its speed goals, says Jochen Hermann, Chief Technical Officer of Mercedes‑AMG GmbH.
Mercedes has added an entry-level version of the elegant SL-Class Roadster to the lineup. The Mercedes-AMG SL 43 has half the engine of its AMG SL sibling, a 2.0-liter turbocharged M139 four-cylinder engine. single This Formula 1 racing technology uses the same 48-volt electrical system that powers the starter-generator. A small electric motor in the turbo rotates the turbine shaft to take in the exhaust gases. The engine has better throttle response. especially Throughout the entire engine rev range while also increasing the performance in high cycles as well
The SL43’s 2.0-liter M139 four-cylinder petrol engine produces 381 hp (284 kW) at 6,750 rpm and 480 Nm (354 lb-ft) of torque at 3,250 rpm and constant. Up to 5,000 rpm, the starter-generator system in the 48V Mild Hybrid can also provide an additional 14 hp (10 kW). The aggressive hybrid for the transmission uses a 9-speed MCT transmission (AMG SPEEDSHIFT MCT 9G (automatic transmission with wet multi-disc start-off clutch) sending power to the rear wheels.
The wet start clutch replaces the torque converter. Slightly reduced weight and with lower inertia thus optimizing the response to accelerator pedal inputs. New software that controls the operation of the powertrain. The AMG SPEEDSHIFT MCT 9G can shift gears with a quick jump if necessary. In addition, the intermediate throttle function in the “Sport” and “Sport+” modes optimizes performance for attractive gear shifts. Especially emotional. The RACE START function provides the best acceleration from standstill to the maximum rpm in 7th gear.
New compressed air technology As used in the Mercedes-AMG F1, a 4 cm thick electric motor is added to the core of the turbocharger. The electric motor rotates at high rpm. to drive the turbine shaft directly, which Mercedes-AMG says “immediately improves responsiveness. From idle speed to the entire engine speed range, it responds faster than before, improving acceleration performance. Boost pressure is also maintained. When the driver withdraws the foot from the accelerator as well
Acceleration from 0-100 km/h in 4.9 seconds and a top speed of 273 km/h. The AMG Speedshift 9-speed multi-clutch transmission has a new ratio adjustment. To continuously reduce the torque in all positions, Mercedes Chief Technical Officer Jochen Hermann said: “Electric exhaust turbochargers. It’s an interesting example of the widespread transfer between Formula 1 technology and real-world vehicle development.
Powerful M139 four-cylinder engine It can bring out the potential of the car in the form of Mercedes-AMG High Performance Powertrains. This technology increases agility and makes driving more enjoyable. At the same time, the efficiency of the drivetrain and support system has been improved.
The SL 43 has an exterior design that adapts perfectly to the times. Curved front and rear bumpers, 19-inch AMG alloy wheels are standard equipment. With additional options with 20-inch or 21-inch AMG wheels, lightweight fabric roof It takes 15 seconds to open-close and can be opened or unfolded to close when the weather is not favorable. at a speed not exceeding 60 kilometers per hour
smaller engine This means less mass at the front, giving the SL 43 nimble handling characteristics. Further refinements have been made with lighter torsion bars to enhance grip. The SL 43 has vents on the lower front panel. as well as the smooth back panel. Without vertical air vents, the AMG SL 43 uses oval-shaped exhaust pipes. All cool SL features available on SL55 and SL63 including Rear Wheel Steering.
