Set to make their world debut at the Geneva Motor Show next month, the Estate, like the sedan, slots in above the already rapid AMG-E43, but with power coming from the same 4.0-litre bi-turbo V8 developing 420 kW and 750 N.m of torque in the former and a monstrous 450 kW and 850 N.m in the S.
As the name implies, both send their grunt to all four wheels via Benz's 4Matic all-wheel drive system, with a nine-speed Speedshift dual-clutch gearbox being the only option.
Calibrated to provide for an even torque split between front and rear axles, the S also features a unique drift mode that sends most of the power to the rear wheels, while a special RACE mode its included as part of the standard issue four mode (Comfort, Sport, Sport Plus and Individual) AMG Dynamic Select system.
Available with Benz's three-mode air suspension and speed sensitive power steering with three modes; Comfort, Sport and Sport Plus, the S also comes fitted as standard with dynamic engine mounts, electronically controlled limited slip diff as opposed to the normal E63's mechanical setup, and optional carbon ceramic brakes.
Inside, the Estate mimicking its sedan sibling with both models featuring a AMG performance steering wheel finished in black Nappa leather as standard, AMG sport seats, carbon fire inserts and the now familiar 12.3-inch instrument cluster display.
Given South Africa's distain for station wagons, don't expect to Estate to became available locally after the commencing of European sales in June.
