2012 Mercedes-Benz SLK by Carlsson

Article by Christian A., on June 15, 2011

With the arrival of summer, tuners are expected to bring out their upgrade kits for the convertibles. One such example is the package that German aftermarket developer Carlsson created for the 2012 Mercedes SLK. It features interior and exterior modifications as well as performance tweaks.

The Carlsson SLK was fitted with different aerodynamic improvements such as a new front spoiler and a rear apron insert (priced at EUR620 each), stainless steel grille inserts (which cost EUR449) that replace the standard honeycombs, a couple of new side sills, and a stainless steel sport exhaust system with oval shaped end pipes that are offered at EUR1,298.

This upgrade package also features a 30 mm lower suspension, customized 18-inch wheels (with a price tag of EUR1,930) and one of three interior kits that include seats, headrests and door panel upholstery that have a starting price of EUR3,900. In terms of performance, the tuners concentrated on the new generation CGI engines that power the 2012 Mercedes SLK.

They provide a power boost between 27 and 40 hp via the C-Tronic control units that are available with a three-year warranty. When taken separately, the upgrades give the SLK 200 CGI an output of either 211 or 224 hp, over the standard version’s output of 184 hp. In addition, the SLK 250 CGI can develop 231 hp rather than 204 hp. The power upgrades have a price range of EUR1,190 Euros to EUR1,690.

The car’s 30mm lower centre of gravity improves dynamic performance without compromising comfort. As an additional upgrade touch, a suspension lowering kit (worth 309 Euro) can be used with larger tyres up to 20 inches. A selection of complete wheel sets from 18 to 20 inches is priced from 1930 Euro.

The SLK interior is made more premium by Carlsson's own Gut Wiesenhof-based upholstery masters, who have set new material and colour combinations that can have customised stitching and beading if desired. Carlsson Nappa, Carlsson Nappa Exclusive and Carlsson Nappa Exclusive Heavy Weight are included in a basic package that covers the upholstery of two seats, the headrests and the door panels.

These are priced from 3900 Euro. Fitting is included. Additional embellishment can be done for both automatic and manual vehicles by using brushed aluminium pedal pads with Carlsson logos, the Carlsson gear shifter with Alcantara appliqués, and either custom fine wood inlays or carbon features.

Two seats, a long bonnet, short overhangs, an open top and the engine in just the right place. With the new SLK, Mercedes-Benz presents what is probably the finest roadster in its history. Yet Carlsson still finds numerous ways to personalise the car's interior and exterior and to leave its own unique mark on its dynamism and style.

The aerodynamics system, consisting of a front spoiler and rear apron insert (for cars with the AMG sports package, code 950), underscores the car's sporty geometry and guarantees an additional downforce at the rear axle (the front spoiler and the rear insert are available for 620 Euro each, excluding VAT). The car's front is perfected by the new front spoiler lip RS (available for 549 Euro and optional in real carbon) while the grille inserts made from electropolished stainless steel (449 Euro) replace the standard synthetic honeycombs in the front apron. The rear view meanwhile is dominated by the stainless steel sports silencer with two stainless steel pipes left and right in the typical oval Carlsson shape (available for 1298 Euro). The acoustic engineers at Carlsson have developed an amazing sporty sound in a way that optimises flow and really underscores the character of the SLK. The diffuser insert and the well-designed rear spoiler cause the contact pressure at the rear axle to increase even further.

Carlsson has drawn on its years of experience in enhancing engine power to present, for the first time, the Carlsson C-Tronic for the current generation of CGI engines. Thanks to the additional control units, the engine power is boosted by anything between 27 and 40 hp. The new C-Tronic makes use of the unit's existing reserves and, thanks to the connection to the car's electronics system, ensures that the relevant safety limits are adhered to and that the engine is not exposed to any excessive wear. Through elaborate endurance testing, Carlsson has developed a new generation of additional control units for the current four-cylinder CGI engines. Durability is guaranteed by the car maker by way of a three-year warranty, valid from the date of installation.

The C-Tronic CB20 enables the SLK 200 CGI to achieve 211 hp (155 kW) while the C-Tronic CB20S allows it to reach 224 hp (165 kW), compared with the standard model's basic power of 184 hp (135 kW). Meanwhile, the C-Tronic CB25 boosts the power of the SLK 250 CGI from 204 hp (150 kW) to 231 hp (170 kW) while the CB25S enables the engine to achieve 239 hp (165 kW). (The C-Tronic CB20 and CB25 are available for 1190 Euro and the C-Tronic CB20S and CB25S for 1690 Euro.)

The lowering of the car's centre of gravity by up to 30 millimetres further increases the car's dynamics without impacting upon comfort levels. Furthermore, the suspension lowering kit (309 Euro), used in conjunction with tyres of up to 20 inches, add the final touches to the car's upgrade. Complete wheel sets starting at 18 inches are available from 1930 Euro.

The interior of the SLK receives an upgrade from Carlsson's own upholsterers based at Gut Wiesenhof. These experienced master upholsterers have come up with a combination of colours and materials for the SLK, which can, if the customer requires, be personalised with matching beading and stitching. Carlsson Nappa, Carlsson Nappa Exclusive and Carlsson Nappa Exclusive Heavy Weight are offered as part of a basic package consisting of the upholstering of two seats, the headrests and the insides of the doors and are available from 3900 Euro including fitting. The interior is further refined by the use of pedal pads made of brushed aluminium with Carlsson logos (suitable for both automatic and stick-shift vehicles) as well as the Carlsson gear selector with Alcantara appliqués, individual carbon features or, alternatively, fine wood inlays.
