A facelifted version of the Mercedes-AMG S 63 Coupé has been spotted testing in Germany. The test mule offers a glimpse of the styling tweaks we can expect when the refreshed Bentley Continental GT rival arrives in two years.
The most prominent styling revisions include an all-new main grille and a restyled front bumper, with a different lower grille that now features three vertical slats and smaller side intakes on the bumper.
This test mule’s grille is completely disguised, but our sources think it will feature a new design that incorporates Mercedes’ familiar vertical chrome bar and large badge.
Styling changes at the front are echoed at the rear, where a new bumper does away with the current car’s side intakes and the rear diffuser surround appears to have a smoother design.
Insiders predict a small increase in power for the facelifted model. Currently, the car’s twin-turbocharged V8 engine produces 576bhp and 663lb ft of torque. That's sufficient to take the super-coupé from standstill to 62mph in 4.2sec and onto a limited top speed of 155mph.
Bentley is expected to launch an all-new Continental GT in 2018. That car looks set to gain the option of a 600bhp W12 engine, which suggests that Mercedes’ facelifted S 63 will have to raise its output towards this figure to stay competitive.
