Mercedes-Benz SLC starts testing ahead of early 2016 reveal
Facelifted Mercedes SLK to morph into new SLC as part of range-wide name changes, with styling, interior and mechanical upgrades planned
The first prototypes of the facelifted Mercedes-Benz SLK have hit public roads in Germany ahead of a planned unveiling at the Detroit motor show in early 2016.
The facelifted two-seater will be renamed SLC as part of a series of recently announced changes to Mercedes' naming strategy.
The car is planned to receive a number of subtle exterior styling tweaks aimed at carrying it through to 2018, when an all-new, fourth-generation model is scheduled to appear.
Among those changes is the new rear bumper and altered tailpipe treatment sported by the prototype pictured above.
Further planned changes not yet adopted on the early engineering mules – spied testing close to Mercedes-Benz’s research and development centre on the outskirts of Stuttgart this week – include a reworked front bumper styled to provide the SLC with a more pronounced grille treatment. Company insiders describe the grille as being reminiscent of that of the new GT.
The new front-end styling will be allied to new headlamps with integral LED daytime running lamps and updated internal graphics, a revised bonnet, altered chrome highlights within the flanks, restyled exterior mirror housings, wider sills underneath the doors and a new range of alloy wheel designs.
Revisions to the SLK’s folding hard-top roof are also planned to provide it with speedier operation, although its basic shape is not expected to alter in the change to SLC.
Inside, Mercedes-Benz plans comprehensive upgrades to provide the SLC with a more premium feel. Among the new changes will be new instruments, round ventilation units, new switchgear and a revised Comand infotainment system featuring a larger, free-standing monitor and simplified operation through an altered rotary dial.
Mercedes is remaining tight-lipped on the mechanical changes planned for its rear-wheel-drive roadster, although sources confirm a revised turbocharged 2.0-litre, four-cylinder engine will provide the new SLC250 with an additional 7bhp over the existing SLK250, at 211bhp.
Further up the range, a new turbocharged 3.0-litre V6 is also planned to replace the naturally aspirated 3.5-litre V6, to provide a new SLC400 with 26bhp more than the outgoing SLK350, at 333bhp.
The prototype pictured above is thought to be one of an extended line of future AMG Sport models. Likely to badged SLC450, it is planned to run a more highly tuned version of the new turbocharged 3.0-litre V6 with 367bhp.
At the top of the line-up, the SLK55 will make way for a new SLC63 model. It eschews the existing range-topping model’s 415bhp naturally aspirated 5.5-litre V8 for the new 503bhp twin-turbocharged 4.0-litre V8 from the GT.
Gearbox choices will include a standard six-speed manual on four-cylinder engines and either a seven-speed or nine-speed automatic in combination with the updated V6 and V8 units.
