The interior layout, fit and finish
Like all AMG saloons or hatchbacks, the E63 S stays largely true to its Mercedes' roots on the inside. The AMG-inspired elements are mostly decorative – a few carbon-fibre touches here and grey seatbelts there, that sort of thing. Plus it also gets sports front seats with electric adjustment all round, including lumbar support. They’re comfortable over long distances, but not as figure hugging as an M5's or RS6's seats through corners.
There are easy-to-use physical buttons for a lot of the features but the main quibble with the driving position is the E63's a confined footwell: the left-hand side bulges out and restricts the room for your left leg and offsets the pedals to the right. That problem also exists in the M5 and RS6, but not to the same degree, and they don't have their steering wheel offset to the left, compounding the issue. It is in the E63.
Some folk have also found that the tops of the digital instruments are hidden by the steering wheel, which is electrically adjustable for height and reach by the way, unless you raise the steering wheel up more than feels ideal. You can operate the instrument screen and infotainment screen from touchpads on the steering wheel, which are good once you get used to them, and the rest of the infotainment system is standard E-Class fare.
That means the software can be unresponsive but the screens are high definition and the addition of a rotary controller, between the seats, along with the steering wheel touchpads make it less distracting to use on the move than the Panamera's or RS6's complex touchscreens. The M5's infotainment package is by far the best in the class, though.
Standard equipment includes the usual DAB radio and in-built sat-nav, plus Apple CarPlay and Android Auto, so you can use your phone's navigation apps, wireless phone charging and a punchy 13-speaker, 590-watt Burmester sound system.
It's easier to see out of the rear of the estate compared with the saloon, but neither is generally as easy to see out of as other cars on the class. However, that's not a major concern because you get front and rear parking sensors, a rear-view camera and bright, adaptive LED headlights as standard.
