Mercedes-AMG's top-shelf S-Class coupe and convertible models have recevied new engine options as part of an update for the 2018 model-year.
The German carmaker will drop the 5.5-litre twin-turbo V8 currently used by the S-Class two-door pair, replacing it with the more efficient 4.0-litre motor used in models ranging from the compact C 63 sedan to the supercar-baiting Mercedes-AMG GT R coupe.
The new motor under the bonnet of the S 63 coupe offers 450kW of power and 900Nm of torque - 20kW more than the outgoing engine, as well as improved fuel economy of 9.3L/100km thanks to a new nine-speed automatic transmission.
At the top of the range, the S 65 coupe and convertible retain the 6.0-litre V12 twin-turbo engine that sends 463kW and 1000Nm to the rear wheels through a seven-speed automatic transmission.
While the S 65 has more power, Mercedes says the lighter V8 model and its more sophisticated transmission is the quicker combination, hitting 100km/h in 3.5 seconds as opposed to the V12’s 4.1 second dash.
Both cars feature facelifted looks, gaining a new “Panamericana” grille with vertical chrome strakes, as well as well as a revised bumpers that share “jet wing” style with the latest Mercedes-AMG E 63 S.
Equipped with air suspension as standard, the high-powered S-Class coupe and convertible can lean into corners, minimising body roll to keep passengers comfortable.
The two door S-Class’ cabin remains a plush place to be, with a new steering wheel joining updated seats and twin 12.3-inch digital dashboard displays.
Optional extras include carbon-ceramic brakes, lashings of carbon fibre, a choice of forged alloy wheels and a special track package capable of recording lap times.
The new model will arrive locally in 2018, priced from around $400,000 in coupe form, with the convertible set to sit closer to $450,000 plus on-road costs.
