Mercedes-Benz SLC-Class Roadster · 3rd generation SLK / SLC

R172

The roadster that traded its K for a C.

Production: 2011–2020
Built: 95,977
Renamed: SLK → SLC (2016)
Body: 2-door roadster
Top model: SLC 43

In 2016, Mercedes-Benz retired the SLK name it had used since 1996, rebadging the roadster SLC to align with the rest of the passenger-car range — the car underneath was barely changed.

Launched for 2012 as the third-generation SLK, the R172 carried over the Vario folding hardtop concept one final time, wrapped in sharper, more aggressive styling and offered with four-cylinder, six-cylinder and — in the SLK 55 AMG — naturally aspirated V8 power.

The 2016 facelift brought the SLC name, a fresh nose inspired by the AMG GT, new four-cylinder engines across the line, and the twin-turbocharged SLC 43 in place of the V8; the roadster stayed in production through 2020, the last of the folding-hardtop SLK/SLC line.

R172 interior — A sportier, more driver-focused cabin than the R171 it replaced.

Every model.

10 distinct series across 2012–2020 — from the four-cylinder SLK 200 to the twin-turbo SLC 43, each identified by its chassis, engine and transmission numbers.

Sharper, more aggressive styling marked the third-generation SLK/SLC.

Year by year.

From the 2011 launch to the 2020 Final Edition — the changes that matter when dating an SLK or SLC, including the 2016 rename.

2012
- Third-generation SLK launches (European sales from March 2011): SLK 200, SLK 250 and SLK 350 BlueEFFICIENCY, with the panoramic Vario-roof and MAGIC SKY CONTROL smart glass as options.
- SLK 250 CDI introduced — the first diesel in an SLK (orders from September 2011).
- SLK 55 AMG on sale from January 2012: naturally aspirated M152 V8 with AMG cylinder management and SPEEDSHIFT PLUS 7G-Tronic.
2014
- AMG Sports package renamed AMG Line; minor revisions to standard equipment.
2016
- Mid-cycle refresh (presented December 2015, launched March 2016 for the SLK’s 20th anniversary): SLK renamed SLC, with an AMG GT-inspired nose.
- New four-cylinder line-up — SLC 180, SLC 200 and SLC 300; the diesel becomes the SLC 250 d; 9G-Tronic replaces 7G-Tronic.
- Twin-turbo SLC 43 replaces the V8 SLK 55 AMG as the range-topper.

R172 rear three-quarter view — The 2016 facelift brought an AMG GT-inspired nose and the SLC name.

Four cylinders to a naturally aspirated V8.

Turbocharged fours, two very different V6s, the SLK 55 AMG’s naturally aspirated V8 — and the first diesel ever fitted to an SLK.
