New Mercedes SL Model Names Leak, Reveal Some Surprises

Leaked / 2 Comments

Topping the range will be a new SL73e that will pack around 800 horsepower.

The current Mercedes SL has been on sale for seven years now. As Mercedes' roadster is starting to show its age, sales are rapidly declining. Luckily, a replacement is coming and it has the potential to be very special.

To help the flagging roadster get its mojo back, the new Mercedes SL is being developed by AMG to make it sportier than its predecessor. Earlier this year, we got our first look at a prototype of the new 2021 Mercedes SL, and now new details uncovered by have seemingly confirmed every model name.

According to the publication's inside source, the new Mercedes SL will be offered with as many as six different variants. At the bottom of the range will be the SL43, which will pack a 3.0-liter, twin-turbo six-cylinder engine that currently produces 367 horsepower in other AMG models. All other variants will have a 4MATIC all-wheel drive system.

Also joining the range will be a new SL53e hybrid alongside the standard SL53, which is expected to combine a 522-hp, 4.0-liter twin-turbo V8 with a 48V mild hybrid system, while the SL63 will reportedly use the same setup with an increased output of 612 hp.


Also joining the new SL family will be an SL55 S, but technical details for this new mystery model are unknown. Topping the range will be the Mercedes SL 73e 4MATIC+, which will pack a 4.0-liter twin-turbo V8 paired with an electric motor.

Combined, this setup will develop around 800 horsepower according to the report, making it more powerful than any current Mercedes SL or AMG GT. If this setup sounds familiar, the 800-horsepower hybrid powertrain will also carry over to the upcoming Mercedes-AMG GT73 that we recently spied preparing to battle the Porsche Panamera. The leak hasn't been officially verified, but it does support previous reports detailing Mercedes' plans to give the SL a new lease of life.
