The interior has an even higher-quality look. Highlights include new light (standard) or dark aluminium trim parts with a carbon-fibre finish. The instrument cluster has a new design too. The two tubular instrument surrounds now feature black dials. Red needles also add to the sporty, contemporary design. A large, multifunction, colour TFT display with a screen diagonal of 4.5 inches (11.4 cm) is incorporated between the two dials as standard. The display between the two ventilation outlets in the centre console has been significantly increased in size. The new-generation sports steering wheel, perforated as standard in the grip area, and the DIRECT SELECT lever, embossed with SLC (in conjunction with 9G-TRONIC), also help create a sporty, refined feel. The leather appointments have also been revised. As a control and display system for navigation, phone, audio, video and internet, the COMAND Online infotainment system offers a range of new and extended features. The new SLC is intelligently networked and “always on”. This is ensured by the standard-fit communications module (on-board SIM card) which enables the use of Mercedes me connect services. The Audio 20 CD entertainment system has also been upgraded.
