The car wears a large rear wing and a prominent front spoiler, suggesting it will produce genuine downforce to enhance track performance and hinting at a more powerful version of the C 63’s ‘hot-vee’ twin-turbocharged V8 under the bonnet.
The most powerful C 63 on sale at the moment is the C 63 S, which produces 503bhp from its 4.0-litre unit. But as shown by the hardcore 577bhp GT R, significantly more power can be extracted from this engine.
The GT R’s 4.0-litre petrol engine uses different turbochargers, reworked engine mapping and a higher compression ratio to offer the additional grunt, but it's not yet known whether the C 63 R will get exactly the same specification of engine.
We do know that, like the AMG GT R, the C 63 R will shed some weight due to the use of carbonfibre parts and possibly a set of aluminium wheels and a titanium exhaust system.
The results will make for a car that’s both significantly quicker off the line and faster around corners than the C 63 S, which reaches 62mph in 3.9sec. The C 63 R’s arch rival, the BMW M4 GTS, manages the same sprint in 3.8sec, suggesting the new Mercedes will have the edge on performance.
Pricing should increase substantially on the C 63 S, which starts at £67,450. If the M4 GTS is anything to go by, something in the region of £120,000 is possible.
Why no Mercedes-AMG C 63 Black Series?
While not confirmed by Mercedes, a hotter version of the C 63 has been expected for some time. Originally thought to come in the form of a C 63 Black Series, it now seems that Mercedes will opt to use its R badge to name its extra-hot coupé.
"It won’t be here soon because Black Series cars tend to come towards the end of a car’s production cycle, but an AMG GT Black is a car we must do,” he said.
Mercedes is likely to stick with its S and R naming conventions, as demonstrated by the AMG GT S and GT R models, until that first new Black Series model lands.
