The Mercedes-Benz SL is a roadster manufactured by Mercedes since 1954. The designation SL derives from the German Sport Leicht, or Sport Light — and was first applied to the 300SL 'Gullwing' named also after its "gullwing" or upward-opening doors.
The term SL-Class refers to the marketing variations of the vehicle, including the numerous engine configurations spanning five design generations.
1954 to 1962
|1954 Mercedes-Benz 300SL Gullwing Coupe|
|Wheelbase||2400 mm (94.5 in)|
|Length||4520 mm (178 in)|
|Width||1790 mm (70.5 in)|
|Height||1300 mm (51.1 in)|
The 300SL roadster succeeded the Gullwing in 1957. The 4-cylinder 190SL was more widely produced with 25,881 units, starting in 1955. Cars of the open SL-Class were available as a coupe with a removable hardtop or as a roadster with convertible soft top or with both tops. Production for the 190SL and 300SL ended in 1963.
1963 to 1971
|1971 Mercedes-Benz 280SL|
Next came the SL-Class 230SL, a new design with a 2.3 six cylinder engine, low waistline and big curved greenhouse windows, and a Coupe Roadster whose distinctive roofline earned the nickname "pagoda top." Around 1968 the engine received a displacement increase and the model became known as the 250SL. The last two years of production as the 280SL saw minor changes to switch knobs, and wheel trim rings became full hubcaps.

The 1989 Mercedes SL base model was the 228 hp (170 kW) 3.0 L inline 6 300SL version in the US. In Europe the base model was the 190 hp (140 kW) 3.0 L inline 6 300SL with 12 valves, and the 228 hp (170 kW) 3.0 L inline 6 with 24 valves is known as the 300SL 24 . But it was the 322 hp (240 kW) 500SL (known as the 560 SL in USA) (with a 5.0 L V8 engine) which made the most headlines. The specification was high, with electric windows, mirrors, seats and roof.
1994 saw a mild facelift for the SL, and the 300SL was replaced in Europe by the SL280 and SL320 (with 2.8 L and 3.2 L I6 engines). The SL500 continued with the same powerful engine. A 389 hp (290 kW) 6.0 L V12 SL600 topped the range in 1993.
The SL320 replaced the 300SL in the United States in 1995, but the SL280 was not offered. The 6-cylinder SLs were dropped from the US lineup in 1998, leaving just the V8 and V12. The SL500 got a new 302 hp (225 kW) 5.0 L V8 for 1999.
The extremely rare SL73 AMG was sold through AMG in 1995, and at 525 bhp (391 kW) it offered the most powerful V12 engine ever put into an SL up to that time. After a brief gap, the SL73 was offered again from 1998 to 2001, although the engine was slightly updated to be more reliable. The same 7.3L V12 was later used by Pagani in the Zonda. A total of 85 SL73 AMG roadsters were built. The SL73 was briefly reintroduced in September 1999 following the SL's end of life facelift and a limited number were produced up until December 2001. The facelifted SL73 is the car that appears in the picture (below left).
Even more rare is the Mercedes-Benz SL70 AMG which was powered by a 7.0 L V12 engine.
The SL60 AMG was also extremely rare. Sold through MB from 1996 to 1998, it used a 6.0 litre V8 engine producing between 381 bhp (284 kW) and 384 bhp (286 kW). AMG claimed a 0-62 mph (100 km/h) speed of 5.8 seconds. Its top speed was limited to 155 mph (249 km/h), but with the limiter removed, it was capable of approximately 185 mph (298 km/h). AMG later unofficially admitted that 0-60 mph was closer to 5.0 seconds and the engine produced between 405-410 bhp.
The SL55 AMG was sold through AMG in the R129 bodystyle from 1998 to 2001 in limited quantity. It was the predecessor of the production R230 SL55 AMG sold from 2003 to 2008.
Only about 300 cars in the SL-class were customized by AMG prior to 2003.

In 2001, an all-new SL (initially just a 5.0 L SL500 version) featured a retractable hardtop (marketed as the Vario Roof) available on the SLK since 1997. A 5.0 L 302 hp (225 kW) V8 was optional, with a 5.4 L AMG V8 appearing in 2003's SL55 AMG. V12 engines are available in the SL600 and the limited-production SL65 AMG.

The facelifted 2008 SL model was revealed in the Geneva Motor Show in March. The 2008 SL gets a new front end reflecting Mercedes's new design philosophy, with a pair of long powerdomes on the bonnet and a single-bar grille replacing the old three-bar effort. Also improvements have been made on the engines as the 3.5L V6 is uprated to 311 PS (229 kW; 307 hp) at 6500 rpm. Compared to the previous 3.5-litre engine, the output has been boosted by 16 percent. Torque has also been improved adding 10 N·m (7.4 lb·ft) to the previous 350 N·m (260 lb·ft) making it 360 N·m (270 lb·ft). this engine now can rev up to a max of 7200 rpm for a period as the oil temperature and other engine parameters permitting, a higher compression ratio, a new intake manifold and extensively modifying and lightening the valve train. In this case, however, the extra power does not come at the expense of fuel economy: with a consumption figure of 9.9 litres per 100 kilometres, the new SL 350 undercuts the previous model developing 200 kW (272 PS; 268 hp) by 0.4 litres per 100 kilometres. Mercedes-Benz is extending the SL-Class line-up by introducing an attractive entry-level model in the shape of the SL 280 developing 170 kW (231 PS; 228 hp). The six cylinder powerplant delivers its peak torque of 300 N·m (220 lb·ft) from 2500 rpm and accelerates the roadster from 0 to 100 km/h (62 mph) in 7.8 seconds, whilst fuel consumption (NEDC) is just 9.4 L/100 km (30 mpg-imp; 25 mpg-US). It will feature the AIRSCARF heating system used in the SLK.
The facelifted SL loses AMG's 5.4L M113 in favor of the newer M156 6.2L V8 used in the S63 AMG, CLK63 AMG and C63 AMG. It produces 525 PS (386 kW; 518 hp) at 6800 rpm and 630 N·m (460 lb·ft) of torque at 5200 rpm. It can accelerate from rest to 100 km/h (62mph) in 4.6 second going up to a limited top speed of 250 km/h (155 mph). The SL63 AMG also includes the new AMG-developed 7-speed MCT "Multi Clutch Technology" semi-automatic transmission.
The new MCT transmission is essentially the 7G-Tronic transmission without a torque converter. Instead of a torque converter, it uses a compact wet startup clutch to start the car off, and also supports computer-controlled double declutching. The MCT (Multi-Clutch Technology) acronym refers to a planetary (automatic) transmission’s multiple clutches and bands for each gear.
The MCT is fitted with four drive modes: “C” (Comfort), “S” (Sport), “S+” (Sport plus) and “M” (Manual) and boasts 100 millisecond shifts in "M" mode. the new car features the new AMG DRIVE UNIT with innovative Race Start function. The AMG DRIVE UNIT is the central control unit for the AMG SPEEDSHIFT MCT 7-speed sports transmission and all driving dynamics functions. The driver can change gears either using the new AMG selector lever with its leather/ carbon-fibre finish, or by nudging the AMG steering-wheel shift paddles. The new Race start Function is a launch control system which enables the SL 63 AMG driver to call on maximum acceleration, while ensuring optimum traction of the driven wheels. A modified version of the SL 63 is the safety car for the 2008 Formula One season.
The new SL65 AMG Black Series coupe features a carbon-fiber fixed roof, front fenders, hood, trunk lid and front and rear aprons. With the absence of retractable roof hardware, the car is more than 550 pounds lighter than the standard SL. AMG placed a modified version of the 6.0-liter AMG V12 engine that now delivers 670 bhp (500 kW) and 738 lb·ft (1,001 N·m) of torque. Its twin turbochargers are 12 percent larger, passages for intake air and the turbo wastegates have been modified, and the intake air intercooler is 30 percent more efficient. The result is 0-to-60 mph (97 km/h) acceleration of 3.8 seconds, and an electronically limited top speed of 198 mph (319 km/h).
