Mercedes AMG Sl 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 (5956 cc) engine producing 381 PS (280 kW; 376 hp) at 5500 rpm. 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.
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 PS (386 kW; 518 hp). After a brief hiatus, the SL 73 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.
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 body style 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 SL 55 AMG sold later, albeit was normally aspirated in the R129 and not supercharged as in its R230 successor. 65 cars were made.
Only about 300 cars in the SL-class were customised by AMG prior to the 2003 model year.
