Minor specification adjustments and mechanical alterations accompany the shift from $154,510 (plus on-road costs) four-door C63 S to $162,400 (plus orc) two-door C63 S, including the addition of 285mm-wide 20-inch alloy wheels on the rear. Up front, 19s remain, but the tyres are now 10mm wider at 255mm.
The wider rears slip on the outer of a 50mm-wider track and a redesigned axle with new geometry and uniball joints replacing rubber bushes, aimed at improving traction and response.
Despite a 75kg weight penalty compared with the sedan, the 1725kg coupe is a tenth quicker from standstill to 100km/h, with 3.9 seconds claimed when the duo of turbochargers are boosting the 4.0-litre V8 to produce 375kW/700Nm.
Our first overseas drive indicated it would take a back-to-back drive of the coupe with the sedan to notice the difference.
Standard ‘S’ fare in our country includes AMG engine mounts, performance exhaust and electronic locking rear differential, as well as performance seats with Nappa leather, panoramic sunroof, head-up display and digital television inside.
As is customary with AMG variants these days, an Edition 1 Package will be available on the C63 S coupe from launch. The $10,900 premium over the standard car buys Selenite Grey magno paint with yellow, an aerodynamics package, carbon ceramic brakes and black/yellow wire-mesh 19/20-inch alloy wheels.
Although a middle-tier Mercedes-AMG C43 coupe is still yet to debut, a C300 coupe is available from $83,400 with a 2.0-litre turbocharged four-cylinder engine producing 185kW and 370Nm, and claiming a 6.0sec 0-100km/h.
Helping justify its $14,500 premium over the C250 sedan on which it’s based, the C300 coupe adds 25kW, a sports exhaust, AMG body styling kit, memory seats, 360-degree camera and Burmester premium audio.
The C-Class coupe range starts with the C200 from $65,900 (135kW/300Nm, 7.3sec 0-100km/h) and C250d from $74,900 (150kW/500Nm diesel, 6.7sec 0-100km/h), both commanding a premium of between $4000 and $5000 over the sedan.
