Mercedes has presented in society the new AMG SL. The traditional convertible has passed into the hands of the sports division, developing a completely new model, and with four seats that has abandoned the roadster format. But one of the great novelties is the access version, the AMG SL 43 that debuts a new electrified four-cylinder engine.
We had been confirming it since the first prototypes of the new Mercedes-AMG SL They began to see the light. The new convertible has already been officially released, it has gone into production and progressively the European countries are receiving the prices, which will hit the market from next summer. A very innovative model also on a mechanical level because, for the first time, it will not only have the brutal V8 engine under the hood, but also the access version has half the number of cylinders.
How do you read it? The new Mercedes-AMG SL 43 It is the access option to the Mercedes model range, the most affordable in price and also the one with the least benefits, but also a real beast. Aesthetically, there are no differences in depth with the rest of the versions announced with a V8 engine, so it will only be identifiable by the emblems on the front wings with the inscription “Turbo Electrified”for the four spherical and chrome exhausts that it presents in two pairs on the backand by the 19-inch alloy wheels as standard, although as an option it can reach no less than 21 inches.
Mercedes-AMG SL 43, a sophisticated access version
Inside, the new Mercedes-AMG SL 43 does not envy the versions with twice as many cylinders, keeping the cdigital instrument cluster under the visor and the large touch screen that the center console has become. However, the less character is noticeable in the upholstery of the seats, in a combination of ARTICO imitation leather and fabric, with other combinations of nappa leather and the front seats with sportier contours remaining as an option.
The steering wheel is covered in leather with seams in gray, although with a surcharge they can be requested in another color such as red or yellow. The same happens with the decoration of the dashboard that, as standard, is presented in “Piano Black”, while as an option it can have aluminum or carbon.
The new Mercedes-AMG SL 43 is offered exclusively with rear-wheel drive and 9-speed automatic transmission “AMG Speedshift”, debuting a new 2.0-liter turbocharged in-line four-cylinder propellant block, with a maximum power of 381 hp. The same figures as the AMG A 45, since it is the same “M139” engine but subjected to a major overhaul. Equipped with «EQ Boost» technology, through a 48-volt belt-driven starter motor momentarily generates an extra 14 hpoffering benefits that you can see detailed below.

The new AMG SL 43 offers unrivaled performance and efficiency
Although it was planned to be a world first in the new AMG C 43Finally the chosen one has been the new Mercedes-AMG SL. The revision has been so deep, that it is the first model on the market to have an electric turbocharger in the exhaust system, which provides an extremely fast response. Mercedes-AMG has managed to integrate a tiny electric motorjust 40 millimeters wide, on the turbo axis, between the turbine wheel on the exhaust side and the compressor wheel on the intake side.
Its operation is controlled by the 48 Volt electrical network, turning at a maximum of 170,000 rpm, so it accelerates the compressor wheel before the exhaust gas enters, increasing engine torque at low revolutions. The Germans have achieved maintain the boost pressure in more or less unfavorable conditions. For example, when going full throttle with stationary output, with the accelerator pedal pressed, braking or decelerating. The new electric turbo will always offer an immediate response. The system is also connected to the main cooling of the four-cylinder block so that the circuit also controls the special cooling of this electric turbo.
