R171 represents the second generation of Mercedes-Benz SLK and is slightly larger than its predecessor the R170. The Mercedes-Benz SLK-Class is a luxury roadster built by the German manufacturer Mercedes-Benz since 1997. The nomenclature was designated to reflect the company's intentions for the car - that it be Sportlich (sporty), Leicht (light), and Kurz (short). Production ran from 2004 until 2011 when it was replaced by the R172.
Like its predecessor, the R171 featured a retractable hardtop. By the time the R171 was released, this had become an increasingly common feature in almost every newly introduced convertible, especially in Europe. The redesigned SLK was introduced in 2004 with a new Formula One-inspired appearance. The exterior design created by Steve Mattin in 2000, also took design cues from the Mercedes-Benz Vision SLA concept car, presented in 2000. Design work was frozen for production in 2001. The vehicle was unveiled in 74th Geneva International Motor Show. Mercedes-Benz SLK-Class went on sale in Europe in 2004-03-27.

For the facelifts: SLK 280 fuel economy was improved while CO2 emissions were reduced. In addition to power boosts on SLK 200 KOMPRESSOR and SLK 350, engine speed limit was raised to 6800 rpm, with temporary boost to 7200rpm across the family (except SLK 55 AMG). Other changes include a higher compression ratio, a new intake manifold and an extensively modified valve train.

"Edition 10" (2007)
It is a version commemorating the 10th anniversary of SLK-Class vehicles. The concept vehicle originally appeared in 2006 Paris Motor show and was based on SLK 280 with 7G-TRONIC transmission, matt-grey metallic body; dark-grey painted, high-sheen light-alloy wheels in a ten-spoke design with 225/45R17 front and 245/40R17 rear tires; black leather seats and interior with silver-coloured under layer; AIRSCARF neck-level heating system, THERMOTRONIC automatic climate-control system, PARKTRONIC parking aid, COMAND system with Europe-wide navigation.

The vehicle was unveiled in 2009 Geneva Motor Show.
The new R171-platform SLK was again on Car and Driver's Ten Best list for 2005, and it won the Canadian Car of the Year Best New Convertible award. Highlighting its potential appeal to women, New Zealand's Lucire magazine announced it as its 'Car to Be Seen in' for 2005.
In 2008-05-05, Mercedes-Benz announced the sale of 500,000th SLK-Class vehicle.
The Culture of Driving campaign includes a 'Sternschnuppe' (shooting star) TV ad telling a story of a couple on a romantic trip through the mountains in the roadster. The man in the spot - unlike his feminine 'better half' - can think only of his car and the prospects of driving on stretches of road featuring even more exciting curves.
The updated models include the new-look front bumper with a modified air-dam arrangement and a more pronounced arrow shape. The rear end was modified by introducing a diffuser-style lower section that makes the Roadster appear more powerful when viewed from behind. The larger exterior mirrors feature LED indicators with a pronounced arrow shape, while the range of light-alloy wheels is also almost entirely new. Interior was optimised to be more driver-oriented. Instrument cluster was updated to include NTG 2.5 audio and telematics with optional LINGUATRONIC voice-operated control, optional harman/kardon Logic7 sound system.
A "gullwing red" leather option, inspired by the original 300 SL gullwing, is added. Further new additions include nappa leather appointments in "natural beige", which complement the new "pale burr walnut" and "black ash grain" wood trims perfectly.
Direct steering assist system with variable steering assistance becomes an option (standard in SLK 55 AMG).
SLK 55 AMG included a new apron with a black-painted cross strut and side air outlets as well as darkened headlamps.
The vehicles went on sale in April 2008.
The vehicle was unveiled in 2008 NAIAS.
SLK Specific Modifications
- Roof controller: allows roof to be opened and closed by remote control and while driving without holding down the button. (Normally the roof can only be operated under 5 MPH.)
- LED lights: license-plate lights, signal indicators, etc. The brake lights are already LEDs, but only the Indicators on the door mirrors are LEDs.
- CHMSL flasher (Third Brake Light Flasher): flashes the center LED light in strobe or pulses.
- Windblocker: in some markets the car comes with a fabric mesh that fits between the roll bars to block the wind; elsewhere it is sold as part of option package. Mercedes-Benz offers a clip on acrylic glass one as an option/accessory; many other companies offer aftermarket bolt-on options.
- Sport air filters: can be ordered from the factory as a special option in some countries; many aftermarket options available.
