Mercedes-Benz has revealed an updated version of the SL called the Grand Edition ahead of the planned launch of an all-new eighth-generation model engineered by its AMG performance car division in 2020.
Set to make its public debut at the upcoming 2019 Geneva motor show, the SL Grand Edition is planned to go on sale in Australian later this year. It will be sold in two versions: the 270kW turbocharged 3.0-litre V6 petrol engine powered SL400 and the 335kW turbocharged 4.6-litre V8 petrol engine powered SL500.

Each model comes in the choice of four metallic colour schemes, including two black tones as well as grey and white. Also included are standard 19-inch front and 20-inch rear 10-spoke forged alloy wheels as well a sports suspension.

Inside, the SL400 and SL500 Grand Edition models receive a brown leather interior previously offered as an option among Mercedes-Benz’s upmarket designo label.

Grand Edition – this is what especially exclusive Mercedes-Benz special edition models are called. The new Grand Edition models of the SL 450 and SL 550 come with numerous highlights to the interior and exterior that create an even more luxurious driving experience. The exclusive Roadster will arrive in U.S. dealerships in 2020.

The SL Grand Edition is available in Graphite Grey with applications in high- gloss chrome and matte silver to ensure a special look for the front bumper. The Grand Edition models have exclusive 19-inch front and 20-inch rear AMG 10-spoke forged wheels. These are painted high-gloss black and have a high- sheen rim lip and spokes. The badges with the SL Grand Edition logo placed laterally on the mudguards subtly reference the special model’s status.

The designo Tundra Brown Pearl leather with its shimmering metallic surface catches the eye on the interior, with details such as fine diamond quilting, piping in designo Golden Olive Pearl and an embroidered special model logo on the head restraints. The multifunction sports steering wheel is also designed in Tundra Brown Pearl leather. The grip zone is particularly easy on the hand in perforated black Nappa leather. The Grand Edition will also receive the sports suspension, which is lowered by 10 mm for firmer tuning and sportier driving dynamics.

Both the SLC 300 and SLC 43 get the Final Edition treatment, but only the SLC 43 will be offered in yellow.
The SLC 300 comes in Selenite Grey with a gloss black finish on the door handles, mirror caps, and rear brace. It's based on the AMG Line trim, which comes with more aggressive bumpers, a 0.4-inch lower ride height, and bigger brakes. The special edition also gets chrome trim strips on the lower portion of the front bumper, “SLC Final Edition” badges on the front fenders, and gloss-black 18-inch AMG wheels.

Inside, it has nappa leather in black and silver pearl with gray stitching and gray seat belts. Carbon-fiber-look leather is used for seat inserts, the gearshift, and the steering wheel.
The yellow SLC 43 Final Edition adds gloss black on the front splitter, side fins, Mercedes star, mirror caps, rear fascia, and door handles. The wheels are flat black and they mount staggered-size 18-inch wheels. Inside, the look is much like the SLC 300, but the SLC 43 also has a crystal gray 12-o'clock marker and an additional "AMG EDITION” badge on the steering wheel.

Engines aren't changed from other SLCs. The SLC 43 Final Edition features a twin-turbocharged 3.0-liter V-6 that makes 385 horsepower and can launch the car from 0-60 mph in 4.6 seconds. The SLC 300 has a 2.0-liter turbo-4 that spins up 241 hp and pushes the car to 60 mph in 5.8 seconds.

Both Final Edition models will hit the market in 2020 and that is likely the final year for the slow-selling roadster.
The SLC's bigger brother, the SL, is more likely to live on, though in a new, higher-performance package.
