The Mercedes-Benz R129 automobiles were produced from 1989 through 2002. They were sold under the SL-Class model names. The R129 replaced the R107 SL-Class in 1989 and was in its turn replaced by the R230 in 2003 (US).

The R129 was produced as a two-door roadster with an automated (electric) textile tonneau cover. All R129s came standard with an additional hardtop roof that could be fitted as and when desired by having the canvas roof folded down and then by manually attaching the hardtop to the body.

Model history[edit]

Designed in 1984, the R129 was based on the shortened floorpan of the Mercedes-Benz W124[2] and featured many innovative details for the time, for instance electronically controlled damping (optional) and a hidden, automatically extending roll-over bar. The R107's rather dated rear diagonal swing axle gave way to a modern multi-link axle. The number of standard features was high, with electric action for the windows, mirrors, seats and convertible top.

Odometer switched from mechanical to electronic between the 1994 and 1995 models.
Note the slots behind the wheel are different

Starting in 1993 for the 1994 model year, R129 were re-designated. For example, 500 SL became SL 500. Starting in model year 1994, Mercedes-Benz offered special SL models from time to time, such as the Mille Miglia edition cars of model year 1994 or the SL edition of model year 2000.

1994 cars (for 1995 model year) had minor updates for the car

1995 onwards R129s for the 1996 model year featured a minor facelift for the car:

During 1996 for model year 1997, cars were the first year to have an option of the panoramic roof. Also newly available:

A second facelift occurred in 1998 for model year 1999 which featured:

Engine history[edit]

1999 Mercedes-Benz R129 SL500
1999 Mercedes-Benz SL600

Initially, there were three different engines available,

and joined in July, 1992 by the

There was a choice of 5-speed manual or 4-speed automatic for the six-cylinder cars; the V8 and V12 could only be ordered with an automatic gearbox.

In Autumn 1993 Mercedes-Benz rearranged names and models. Also, the 300 SL was replaced by:

Only the 280 was available with a manual gearbox. SL 500 and 600 continued with their respective engines.

A second facelift, introduced in late 1998, comprised new external mirrors, 17" wheels and new bumpers. Also new were the engines,

and

The V12 engine remained unchanged.

The North American Market[edit]

Not all engines were offered in North America. The 1990 Mercedes-Benz SL base model was the 228 hp 300SL version equipped with a 5 speed automatic transmission, but it was the 322 hp 500SL (with a 5.0 L V8 engine) which made the most headlines. For model year 1993, the 600 SL was additionally introduced stateside.

The SL320 replaced the 300SL in the United States in 1994, but the SL280 was not offered. The 6-cylinder SLs were dropped from the US lineup in 1998, leaving just the V8 and V12.

Special Editions[edit]

AMG offerings[edit]

1995–1998 Mercedes-Benz SL 60 AMG
1999 Mercedes-Benz SL 73 AMG

AMG had already offered an SL version while still independent, the AMG 500 SL 6.0 of 1991. After being taken over by Daimler-Benz, there were several AMG SL-models available through D-B dealers.

The SL 60 AMG was the most numerous of these rare cars. Sold from 1993 to 1998, it used a 6.0 litre V8 engine producing 381 PS (280 kW; 376 hp) at 5500 rpm.[5] AMG claimed a 0-62 mph (100 km/h) speed of 5.6 seconds. Its top speed was limited to 250 km/h (155 mph), but with the limiter removed, it was capable of approximately 185 mph (298 km/h). AMG later unofficially conceded that 0-60 mph was more like 5.0 seconds and the engine produced between 405-410 bhp.[citation needed]

Extremely rare was the SL 73 AMG, sold through Mercedes-AMG in 1995, and offering the most powerful V12 engine ever put into an SL up to that time with 525 hp (391 kW; 532 PS). After a brief hiatus, the SL73 was offered again from 1998 to 2001. The same 7.3 L V12 was later used by Pagani in the Zonda. Only 85 cars were made.[6]

Also very rare is the SL 70 AMG which was powered by a 7.0 L (7055 cc) V12 engine developing 496 PS (365 kW; 489 hp) at 5500rpm and a maximum torque of 720 Nm at 3.900 rpm. It was a bored out version of M120 6.0 V12, also with shorter stroke. Produced between 1996 and 1997 in 150 units.

The SL 55 AMG was sold in the R129 bodystyle from 1998 to 2001 in limited numbers (5.4L V8, 354 PS (260 kW; 349 hp) at 5500 rpm). It was the predecessor of the production R230 SL55 AMG sold later, albeit was normally aspirated in the R129 and not supercharged as in its R230 successor. 65 cars were made.[7]

Only about 300 cars in the SL-class were customized by AMG prior to the 2003 model year.

Mille Miglia Edition (1995, 1999, 2000, 2001)[edit]

In 1995 Mercedes released the Mille Miglia edition, to commemorate the 40th anniversary of Stirling Moss's win of the 1955 Mille Miglia road race. The limited edition was available in either SL320 or SL500 guise, came in Brilliant Silver metallic, and had Evo II six-spoke polished alloys, red and black leather interior, carbon-fibre trim and extra equipment. Stirling Moss was given the first SL500 built.

Silver Arrow Edition (2002)[edit]

Silver Arrow Edition

Special edition of 2002 SL 500/SL 600 made to celebrate the race car with the same name (from 1930). Two-tone interior leather on steering wheel and seats, special wheels, etc.

For the US market, only 1550 Silver Arrow units were produced; 100 units of the SL600 and 1450 units of the SL500.

The 2002 Silver Arrow Edition was a prominent feature in the 2001 music video Rollout (My Business) performed by Ludacris.

Other Editions[edit]

Several other editions were released of the 129 body SL. These include:

Diana, Princess of Wales ownership[edit]

Princess Diana's Mercedes 500SL

The R129 came to public attention in 1991 when Diana, Princess of Wales sold her Jaguar XJS to lease a metallic-red 500SL and became the first member of the royal family to use a foreign car. This was not without controversy as it sparked a media storm as it questioned whether a member of a British royalty should drive foreign cars.[8] Media pressure eventually forced her to return the car to Mercedes-Benz in 1992, with whom it now resides in the Mercedes-Benz Museum.[9]
