Mercedes-Benz SLK-Class (R170)

The R170 Mercedes-Benz SLK-Class is the first generation of the Mercedes-Benz SLK-Class range of compact luxury roadsters manufactured by Mercedes-Benz from 1996 until 2004,[2] using a shortened variant of the W202 Mercedes C-Class platform.

With over 300,000 manufactured, the first generation SLK was replaced by the Mercedes R171 SLK in 2004.[3]

The SLK nameplate derives from the roadster's design ethos: to be sportlich (sporty), leicht (light) and kurz (compact).[4] It was sold in North America for the 1996–2004 model years.

Development and launch

The R170 Mercedes SLK is based on the SLK I Concept, presented during early 1994 at the Turin Motor Show, and SLK II Concept, presented during late 1994 at the Paris Motor Show, which is a two-seater roadster concept car that features a folding metal electro-hydraulic roof, dubbed 'vario-roof' by Mercedes, and takes 25 seconds to operate.[5][6] A German design patent was filed on 30 September 1993, with the final production version of the SLK introduced at the Turin Motor Show on 22 April 1996.[7][8] Construction of pre-production test cars began in October 1995,[1] with mass production beginning in July 1996.[1]

The R170 SLK is based on the W202 C-Class platform, sharing many drivetrain and chassis components, as well as using a shortened version of the floor pan.[9] The wheelbase is also identical to the wheelbase of the 190SL and 300SL, at 2400 mm.[10]

The platform of the SLK is also used by the Chrysler Crossfire, which shares 80% of its components with the R170.[11][12]

Equipment

Standard equipment includes power seats, power windows, power steering, dual-zone climate control, dimmable interior mirror, and alloy wheels. Safety features include front and side driver and passenger airbags, anti-lock brakes, and electronic stability control.[13] Options included an AMG body design package, also sometimes called a "sport package" including body colour side skirts, chromed tailpipes, 17-inch AMG alloy wheels on lower profile performance tires, and a sculpted front apron with black-mesh air intakes. Wider wheels were also available on SLK 230 Kompressor models. Other available options included a 5-speed "Touch Shift" 5G-Tronic automatic transmission, heated seats, xenon headlamps, a premium Bose sound system, a trunk-mounted 6-CD changer, 8-way power seats, and a manually telescoping steering wheel. Many of these options were standard on the SLK 32 AMG.[14]

SLK 32 AMG

The SLK 32 AMG was introduced in 2001, designed to rival the BMW M Roadster and Porsche Boxster S.[16] The car features an upgraded version of the M112 engine found in the SLK 320, now featuring a helical twin-screw supercharger and water-to-air intercooler.[17]

The SLK 32 AMG introduced Mercedes' new SpeedShift 5G-Tronic (automatic) transmission, that allows for manual shifting of the gears, and faster automatic downshifts before overtaking.[18] There was no manual transmission option available for the SLK 32 AMG.

The SLK 32 AMG features a more angular steering wheel, AMG instrument dials, an updated front and rear bumper with larger air intakes, and larger brakes; from 300 mm, upgraded to 334 mm in diameter.[19] SLK 32 production started from January 2001, to March 2004. A total of 4,333 were produced; 979 were sold in Germany, 2,056 were imported to the US, and 263 to the UK.[20]
