The new Mercedes-AMG SL is apparently being expanded to include a plug-in hybrid variant. Fresh spy shots show a practically undisguised prototype that at first glance does not differ from the well-known SL types. But there is a striking detail at the rear. There our eyes encounter a flap behind which a connection for a charging plug seems to be hidden.
We hardly dare say it, but the SL also comes as a plug-in hybrid. However, one of the very special kind, provided that AMG uses the drive train from the five-door GT 63 SE Performance. System power: 843 hp.
Combination of the well-known 4.0-liter biturbo V8 and a permanently excited synchronous electric motor on the rear axle. The eight-cylinder from the GT 63 S contributes 639 hp and 900 Nm, which are transmitted to the 4Matic Plus all-wheel drive in the classic 9-speed automatic transmission. There is also a belt-driven starter generator with 14 hp for supplying ancillary units.
The e-machine sends its 204 hp and 320 Nm via an electrically switched two-speed automatic (an electric actuator engages second gear at a maximum of 140 km/h, which corresponds to the maximum speed of the electric motor of around 13,500 rpm) and an electronically controlled one Rear axle locking differential to the rear wheels.
Depending on the gear combination, a maximum torque of between 1,010 and 1,400 Nm is available. The large sedan reaches 100 km/h in 2.9 seconds, in the more compact SL it could be a tenth or two faster.
Mercedes sells the new SL exclusively under the AMG logo, which means all models have the Panamericana grille with vertical slats. Fold-out door handles ensure a smooth appearance of the sides. For the first time since the R 129 from 1989, the vehicle has a fabric roof instead of a folding hardtop. There is an active rear spoiler at the rear.
The interior is reminiscent of the other current Mercedes models. Means: Displays are king. There is a 12.3-inch digital instrument cluster. The 11.9-inch infotainment screen tilts between 12 and 32 degrees, allowing drivers of different heights to adjust the position to their preferences. As with other Mercedes convertibles, the front seats have the Airscarf function, which blows warm air on the occupants’ necks.
For the first time, the SL is also available with all-wheel drive. There is also rear-wheel steering and an optional limited-slip differential for the rear axle, which provides even more control.
