- Mercedes-AMG SL 43: New entry to SL model range with innovative engine technology
Mercedes-AMG presents the SL 43, a technically innovative new entry model for the AMG SL roadster, arriving in U.S. dealerships in summer 2023, starting from $109,9001. Under the hood of the open-top 2+2-seater is a Handcrafted AMG 2.0-liter turbocharged M139 engine featuring an electric exhaust gas turbocharger. This technology is a direct derivative of the development successfully used by the Mercedes-AMG Petronas F1 Team. The new form of turbocharging guarantees spontaneous throttle response across the entire rpm range to deliver an even more dynamic driving experience. The turbocharger is operated via the 48-volt electrical system, which also feeds the belt-driven starter-generator (RSG). As a result, the SL 43 has an output of 375 hp and a maximum torque of 354 lb-ft.
he operating principle of the electric exhaust gas turbocharger is based on the same technology used by the Mercedes-AMG Petronas F1 Team. An electric motor around 1.6 inches (4 cm) is integrated directly on the turbocharger shaft between the turbine wheel on the exhaust side and the compressor wheel on the intake side. Electronically controlled, this drives the shaft of the turbocharger directly and thus accelerates the compressor wheel before the exhaust gas flow takes over the drive in a conventional manner.
This significantly improves immediate response from idle and across the entire rpm range. The combustion engine responds even more spontaneously to accelerator pedal input, while the overall driving experience is more dynamic. In addition, the electrification of the turbocharger enables higher torque at low rpms. This also increases agility and optimizes acceleration from a standstill. Even when the driver takes their foot off the accelerator or applies the brakes, the innovative technology is able to maintain the boost pressure at all times to ensure a continuously direct response.
The turbocharger, which is operated via the 48-volt on-board electrical system, works at speeds of up to 170,000 rpm, which enables a very high airflow rate. The turbocharger, electric motor and power electronics are connected to the combustion engine's cooling circuit to create an optimal temperature environment at all times. In combination with the Handcrafted AMG M139 engine, the innovative technology in the AMG SL 43 produces an output of 375 hp at 6,750 rpm. The 354 lb-ft of torque is available between 3,250 rpm and 5,000 rpm.
The second-generation RSG also functions as a mild hybrid in the 48-volt on-board electrical system enabling functions such as gliding and recuperation to maximize efficiency. The 48-volt technology also increases comfort, as the transitions between the start-stop function and gliding mode function are almost imperceptible.

I really would love to say that I like the new SL's but for some reason they lack the WOW factor and I cant get past the out of place center tablet. Personally I prefer the Lexus LC500.
Amazing
Beautiful car ❤

شُڪرٍآ👑❤
Poor man's sl.
beautiful in everything for now but this is only for now... 😻😏🤳🇧🇾 time will change it... 😜👍 I hope for the better...
