The C63 comes with an electrically adjustable steering column and heavily bolstered sports seats; the S version gets even more figure-hugging, semi-bucket-style ones. Both seat types have full electric operation, so whatever your size and shape you shouldn’t have an issue getting comfortable. They are also supremely supportive, even on long journeys.
Overall, the driving position is very good. Forward visibility is fine but, due to their sloping rooflines, the coupé, convertible and – to some extent – the saloon are trickier to see out the back of when compared with the estate. That said, all-round parking sensors and a rear-view camera are standard, while a 360deg camera is a worthwhile optional extra.
All versions get the C-Class’s top-spec Comand Online infotainment system and sat-nav. This comes with an 8.4in colour screen controlled by either rotary and touchpad controls. The graphics looks great, but it can be tricky to use because the menus aren’t always easy to figure out. Still, while it’s less intuitive than BMW’s iDrive, after some use you do get to grips with it. The rest of the C63’s controls are well laid out.
There’s a real look of quality to the interior, with a plush mix of soft nappa leather, brushed metal and gloss-black plastic surfaces. Despite this, in places the C63 doesn’t feel quite as solidly put together as the BMW M3 and M4, even if it certainly looks more flamboyant.
