The M-Benz SL series has been launched since the 1950s and can be said to be the brand's quite representative roadster, and M-Benz launched a new major overhaul model at the end of 2021, offering a new choice for fans who love convertibles. However, the previously published models are equipped with V8 twin turbo power, and M-Benz has added an additional SL 43 model with a 2.0-liter 4 twin engine as an entry choice, and it is very special that the original factory advertises that this set of power is also built with F1 racing turbo technology.
The original SL 55 and SL 63, both powered by a 4.0-litre V8 twin-turbo engine, can produce a maximum horsepower of 476 and 585 horses respectively. The SL 43, on the other hand, uses an in-line 4-cylinder single-turbo engine, which was originally code-named M139 and uses electric turbo technology derived from F1 racing cars, using a 48V system to bring better output efficiency.
The original plant said that electric turbine technology can use the 48V system to power the motor, so that the motor in the turbine is pre-rotated until there is exhaust gas to push the turbine blades, which can provide better throttle response and increase the efficiency of engine output. The 48V system can also deliver an additional 14 horsepower for smoother acceleration.
According to the data released by the original factory, the SL 43 can output 381 horsepower maximum horsepower, as well as the maximum torque output of 48.9 kg meters, with a 9-speed MCT transmission, it can complete zero hundred acceleration in 4.9 seconds, and the speed also has a strength of 275km/h. The use of a four-cylinder engine also has a positive performance in terms of counterweights, which is expected to lead to more flexible handling reactions.
In terms of appearance, the SL 43 has not been drastically changed, and the more obvious difference is that the trim panels of the front gas dam on both sides of the front of the car have been adjusted in shape. The rim is made of 19-inch aluminum ring, and the owner can also choose a 20-inch or 21-inch configuration. At the same time, the rear wheel steering system, AMG Dynamic Select, 12.3-inch virtual cockpit and other equipment can also be seen. Overall, if you don't have to go for extreme horsepower, perhaps the SL 43 may be a more balanced choice.
