No interior pictures were released, but the first leak showed the cabin will receive the same updates as the standard model. However, to distinguish the high-performance variant, there are unique touches such as heavy-bolstered sport seats, an AMG steering wheel and piano black trim on the center console.
Under the hood, power continues to be provided by a naturally-aspirated 6.3-liter (6208cc) V8 engine with 451 hp (336 kW / 457 PS) and 443 lb-ft (600 Nm) of torque. While this is a bit disappointing, it is connected to a seven-speed 'SpeedShift' MCT transmission which offers improved fuel efficiency and performance. More specifically, the sedan will accelerate from 0-100 km/h in 4.5 seconds and average 12.0 L/100km (19.6 mpg US). Likewise, the estate rockets from 0-100 km/h in 4.6 seconds and consumes an average of 12.3 L/100km (19.1 mpg US).
A bevy of options will be available - including an AMG Performance Package which increases output to 481 hp (359 kW / 488 PS) and 443 lb-ft (600 Nm) of torque - and full details will likely be announced when the car is officially unveiled at the Geneva Motor Show.
