The most powerful version of the Mercedes-AMG SL will make its debut before the end of the year. It is not certain yet if the sports carmaker will called it the Mercedes-AMG SL 63 S E Performance or Mercedes will choose some other name for the car. But one thing is for sure: it will sport more than 700 HP.
For now, the new Mercedes-AMG SL is available in two versions: SL 55 with 476 HP (with a price starting from 158,240 euro) and the SL 63 with 585 HP (starting from 187,098 euro).
But as the AMG chief Philipp Schiemer announced, the range would be completed with a six-cylinder version and a top-of-the-range plug-in hybrid version based on the powertrain from the new AMG GT 63 S E Performance. The powertrain of the AMG GT 63 S E Performance combines the 4.0-liter 639 HP/900 Nm V8 bi-turbo engine with the 48V mild-hybrid tech and a 204 HP/320 Nm electric motor that drives the rear axle. The electric motor gets its power from a relatively small Li-Ion battery of 6.1 kWh gross capacity (4.8 kWh net capacity ). This unit provides the car with an electric range of only 13 km.
SL 63 S E Performance, figures similar to those of the Porsche 911 Turbo S
It’s not yet clear if the upcoming Mercedes-AMG SL top version will have the same very high output as the GT 63 S E Performance 4-door coupe has. The Mercedes-AMG SL 63 S E Performance will have the Porsche 911 Turbo S as its main contender. The 911 Turbo S has 650 HP. Therefore, it is possible that Mercedes will offer a version slotting lower, with an output somewhere around the 700 HP figure.
The Porsche 911 Turbo S promises an acceleration from 0 to 100 km/h (62 mph) in 2.7 seconds. Meanwhile, the Mercedes-AMG SL 63 with 585 HP needs 3.6 seconds to cover the same 0 to 100 km/h gap. The upcoming AMG SL 63 S E Performance or whatever the name of the model will be, will surely approach the figures the 911 Turbo S sports.
