What are the key safety features of the Mercedes SL?

All recent Mercedes SL models come equipped with essential safety tech like airbags, stability control, blind-spot monitoring and lane keeping assist. Newer versions (from 2022) benefit from the latest Mercedes systems, including attention assist and active lane change features, borrowed from the S-Class. Crash test data is limited due to the SL’s low-volume, high-cost status.
What engine options are available with the Mercedes SL?

The current SL range includes the SL 43 with a 2.0-litre turbocharged four-cylinder and the more powerful SL 55 and SL 63 models with 4.0-litre twin-turbocharged V8s. Older models (2003–2021) offered naturally aspirated or turbocharged V6, V8 and V12 engines – all petrol – depending on how much power you want under your foot.
What are the standard technology and infotainment features in the Mercedes SL?

Depending on the model year, SLs come well-equipped with touchscreen infotainment, navigation, Apple CarPlay/Android Auto, heated leather seats and voice control. Newer models (from 2022) include an 11.9-inch touchscreen, digital cockpit, Burmester premium audio and MBUX infotainment with over-the-air updates. Features like wireless charging, Airscarf heated neck vents and advanced voice control add even more luxury to your open-air drives.
What is the fuel consumption of the Mercedes SL?

Official fuel economy ranges from around 21–36 mpg, depending on engine and model year. The SL 43 is the most efficient, while the V8 SL 55 and SL 63 typically return 20–24 mpg combined. Older V8 or V12 models can dip below 20 mpg, so fuel costs are something to consider if you plan on daily or long-distance use.
What should I check when buying a used Mercedes SL?

Make sure the car has a full service history – especially with complex models like the SL. Check that the folding roof works smoothly, all electronics are in good order and that tyres and suspension are in decent condition. For extra peace of mind, book The AA Vehicle Inspection before you buy.
Are Mercedes SL cars reliable?

Generally, yes – later SLs share components with Mercedes’ flagship saloons, benefiting from solid engineering. That said, ageing electronics and convertible roof mechanisms can present issues. Regular servicing and careful ownership are key to keeping things running smoothly.
