2018 Mercedes-Benz SLC-Class Interior Review

Scorecard

Interior: 8.1

The 2018 Mercedes-Benz SLC looks great and features an abundance of premium materials. It matches the quality of other high-end Mercedes vehicles, but it doesn’t hold up as well from a style standpoint. The SLC has a very similar cabin to the SLK – the model it replaced for 2017 – and the SLK already looked dated compared to class rivals.

The cabin isn't the roomiest, but the seats are comfortable. There are plenty of available tech and driver assistance features to make up for the relatively short standard features list. Roadsters aren't known for having large trunks, but the SLC has a usable amount of cargo space as long as the top is up.

  • "Whichever SLC you choose, you'll appreciate the car's cabin, which wouldn't look out of place in more expensive Mercedes sedans, and its grand-touring-style ride comfort." -- Edmunds (2017)
  • The SLC's cabin is virtually unchanged from that of the SLK, where it has appeared dated for some time. The most significant change is its flat-bottom steering wheel, while black-faced primary gauges, a TFT driver-information screen, and a 7.0-inch infotainment screen round out the functional updates. Contrast stitching and elegant silver buttons and switches are less functional, but they're appreciated. A variable-tint glass roof remains an option for those seeking to brighten the cabin, but if you need it brighter still, the retractable hardtop disappears under the decklid at speeds up to 25 mph." -- Car and Driver (2017)
  • "Mercedes-Benz is a luxury-car maker, so it's no surprise that's the biggest strength of the 2017 SLC." -- Kelley Blue Book (2017)

Seating

The SLC seats two and comes standard with leatherette upholstery and power-adjustable sport seats. Leather upholstery, premium Nappa leather upholstery, heated seats, and Mercedes' Airscarf neck-warmer system are available.

Even for a two-seat roadster, the SLC's cabin feels a bit confined. Despite that, the seats are comfortable and the upholstery feels rich, particularly with the available Nappa leather. There are no LATCH connectors for installing car seats.

  • "The main interior drawback for the SLC is that it's quite snug, even by compact roadster standards. The Z4, for example, gives larger drivers more room." -- Edmunds (2017)
  • "Whether covered in MB-Tex faux leather or real hides, the seats are comfortable, even though there's not a lot of room for taller drivers." -- Kelley Blue Book (2017)

Interior Features

Standard features in the SLC include a retractable hardtop with a panoramic glass roof, mbrace Connect, Bluetooth audio streaming, two USB ports, HD Radio, and a 7-inch display screen. Standard driver assistance features include a rearview camera, driver drowsiness monitoring, and active brake assist, which automatically helps you apply the ideal amount of braking pressure.

Available features include a panoramic roof with Magic Sky Control, remote top operation, dual-zone climate control, three additional mbrace packages, push-button start, an 11-speaker Harman Kardon audio system, satellite radio, an in-dash DVD/CD player, Bluetooth phone connectivity, Apple CarPlay, Android Auto, a built-in Wi-Fi hot spot, and the COMAND navigation system with a 7-inch screen. Available driver assistance features include blind spot monitoring, lane keep assist, adaptive cruise control, Pre-Safe (tightens seat belts and rolls up windows before an impending collision), and park assist with front and rear parking sensors.

Some class rivals have more standard features than the SLC. Still, when you factor in the available features, this convertible offers everything you might want in your car, and the audio and climate controls are easy to reach and use. Unlike most other roadsters, the SLC is a hardtop convertible. And not only can you put the top down using the key fob (that's an available feature), you can also add Magic Sky Control, which can alter the transparency of the panoramic center roof panel by using electrical currents to make it lighter or darker.

  • A standard 'attention assist' system can alert the driver to the first signs of drowsiness, a factor that causes more than 100,000 accidents a year in the U.S.A steering sensor is coupled to smart software that uses 70 parameters to establish a unique driver profile during the first 20 minutes of driving. Between 50 and 112 mph, the system identifies the erratic steering corrections drivers make as they begin to get drowsy and triggers an audible warning and a 'Time for a Rest?' message with a coffee cup icon in the instrument cluster." -- Left Lane News
  • "Audio and climate controls are as easily accessed as they are easy to use, and we love the satisfying tactile quality of the knobs and switches." -- Kelley Blue Book (2017)

Cargo

The SLC has 10.1 cubic feet of trunk space with the top up. That's not an outstanding total, but it's decent for a roadster and more than some other luxury sports cars provide. However, with the top down, trunk space drops to just 6.4 cubic feet, which is one of the lowest totals in the class.

  • With the roof up, trunk space checks in at a respectable 10.1 cubic feet, while lowering it down reduces room to 6.4 cubes." -- Left Lane News
  • "On the bright side, the trunk is surprisingly accommodating for a two-door car whether the roof is up (10.1 cubic feet) or down (a still useful 6.4 cubic feet)." -- Edmunds (2017)
