This thread is designated for the rare V12 AMG 7* models.
SL 72 AMG
Extremely rare was the SL 72 AMG, with a 7.1 litres (7,055 cc) engine, sold through Mercedes-AMG in 1995, and offering the most powerful V12 engine ever put into an SL up to that time with 510 PS (380 kW; 500 hp).
SL 73 AMG
After a brief hiatus, the SL 73 AMG was offered with the new M297 engine 7.3 litres (7,291 cc) from 1997 to 2001, with a bore x stroke of 91.5 mm × 92.4 mm (3.60 in × 3.64 in) DOHC 4 valves per cylinder, fuel fed by naturally aspirated Bosch HFM fuel injection and a compression ratio of 10.5:1, producing 386 kW (525 PS; 518 bhp) at 5,500 rpm and 750 N⋅m (553 lbf⋅ft) at 4,000 rpm of torque, which was later used also by Pagani in the Zonda, enabling the SL 73 to set off from 0 to 100 km/h (62 mph) in no longer than 4.5 seconds, while achieving a top speed of above-320 km/h (199 mph). Only 85 cars were made.
SL 70 AMG
Also very rare is the SL 70 AMG which was powered by a 7.1 litres (7,055 cc) V12 engine developing 496 PS (365 kW; 489 bhp) at 5,500 rpm and a maximum torque of 720 N⋅m (531 lbf⋅ft) at 3,,900 rpm. It was a bored out version of M120 6.0 V12 and with a longer stroke. Produced between 1996 and 1997 in 150 units.
