Mercedes SL-class (W113 / / R129 / R230)

W e do not count the 190SL (1955-63) into classic car archive because its engine was seriously underpowered, its technology and style were to but thoroughly eclipsed by the landmark This mean with the of 300SL it is meaningless to talk it.

To me, the real SL started from the 230SL of 1963. This car pushed style, comfort and to a new era. Bye-bye to the round, design of 190SL and welcome to an theme with clean large windows and a unique detachable hardtop. Paul made this car look timeless than most cars born in the same Today, we find this car beautiful than all its successors.

all Mercedes of the time, the 230SL was to purchase. In return, it delivered build quality, solidity and a cabin. Its compact body surprising amount of cabin a useful boot and extra space behind the seats. manner biased towards the side. As Road Track then, the 230SL displayed roll in corner as a result of its springs, but it had excellent damping and an impression of great chassis over bumps. Gearshift of the manual gearbox was found to be but most impressive was the steering, was described to be light, quick, and smooth.

The W113 was developed the components of Mercedes 220 sedan. include its all-independent suspensions up front and low-pivot swing at the rear) and powertrain. The smooth and running 2.3-liter SOHC was bored out from the 220’s and further enhanced by a new injection and injectors. About half of the was injected into the combustion directly to cool the pistons, so it was a direct-injection engine. Output was to 150hp DIN or 170hp SAE gross as a The 230SL could top 124 mph and accelerate 0-60 mph under 10 seconds. It not challenge Ferraris or Jaguar but still it managed high-speed very well.

Later on, the engine was enlarged to and then 2.8-liter, producing and 280SL respectively. The 2.8 engine 20hp more than the car. However, since the of customers chose a 4-speed automatic gearbox, they did not significant change to performance. nearly 50,000 cars the series retired in 1971.

D know why, I have with this SL since the beginning. When I was still a I loved watching Ferraris, Jaguars or simply any beautiful cars, but this Mercedes roadsters just did not gel with me. In my its proportion was ill-conceived, possessing the simplicity of the old car nor the … lines of roadsters, say, Alfa Spider or Ferrari 308GTS. the slightly strange-looking Jaguar XJS was to appreciate. Admittedly, when I watched the R107 SL, it was already than 10 years old… I don’t understand why people saying it was a beautiful car or a timeless You can make your own judgment.

history tells us R107 is the running Mercedes of all, survived for 18 years (from to 1989). As a result, it was also the selling SL, having sold units. For this reason, it is the definitive Mercedes SL in many mind.

Compare with the old R107 had grown larger and a lot The weight gain was primarily due to crash protection (thanks to a chassis and strengthened windscreen more luxurious trimming and the of V8 engines for the first time. was powered by the company’s new iron-block SOHC V8 with 200hp on However, blame to the weight and the 4-speed automatic gearbox, its was mediocre, topping 126 mph and taking 9.3 to accelerate from zero to In America, tighter emission drove Mercedes to equipment its US with 4.5-liter V8 instead. so, it was slower than the European

Throughout the years, a variety of were available to the SL, producing (185hp DIN), 300SL DIN), 350SL (200hp 380SL (218hp DIN or 155hp 420SL (218hp DIN), (225hp DIN or 190hp SAE), (245hp DIN) and 560SL SAE). However, only and 560SL were capable of 0-60 in less than 8 The R107 was never a performance It was more about comfort and of driving.

Three body were offered: roadster, hardtop and fixed hardtop They were pictured in the same sequence. The fixed coupe was called SLC (e.g. Among the 300,000 units of sold, some 63,000 the SLC. Suppose to fill the left by S-class coupe, it had the short wheelbase stretched by a 360 mm to accommodate rear seats. the resultant look was compromised, and the result show that it was not a It was axed in 1981 when the SEC coupe arrived.

Now looking I think the popularity of R107 was not to any technical or styling achievement, but the market had few alternatives. In fact, XJS convertible was its only direct others like Porsche 911 and Ferrari Mondial cabriolet clearly more sport-oriented. To doubting the build quality and of Jaguar, choosing the Mercedes SL was

W hen the R129-series 500SL was launched in it caused a lot of sensation to me. Compare to the R107, it was virtually a revolution. Its new design was handsome and futuristic. Cd to merely 0.31 with on. The chassis got even stiffer and It featured the world’s first rollover protection bar, rose above the occupants 0.3 second. Its roomier cabin a fully automatic soft top and adjustable everything with Its chassis rode on all-new with modern multi-link replacing outdated semi-trailing for better control. Electronically damping and ASR traction control further sophistication.

The engine range was overhauled. All bar the entry-level 300SL got 4-valve and variable valve timing As a result, power and performance a big leap. 300SL-24 had its 3-liter enhanced to 231 horsepower, giving the machine decent performance. headline model must be the new whose 5-liter V8 now produced a 911 Turbo-beating 326hp. This let to time a remarkable 0-60 mph in 5.9 seconds and a top speed of 157 mph, if the 155 mph was not very accurate. For the first the Mercedes SL was capable of challenging for straight line performance.

In the SL was not as good as Porsche. Although it had chassis balance, communicative and strong brakes, its excessive and near 2 tons of weight it from challenging real cars. There is still a drawn between a luxury tourer and a lightweight sports However, as Autocar described, an open-top GT the 500SL was close to It was the world’s greatest convertible.

In Mercedes 6.0-liter V12 (408hp) the range and created the new flagship However, due to extra weight the car was no than 500SL. Its higher and running costs means was still the pick of the range.

In all models were renamed to the new corporate nomenclature. In the late the 4-valve V6 and V8 were replaced new generation 3-valve family for emission. Performance barely The R129 remained in production 2001. It was not as long-living as its predecessor, but it was competitive throughout its life and the world’s best luxury until its last day.

H repeated again when the new SL-class was launched in 2001. It the world with quantum in style, technology and luxury. On the its body shape was polished to be sleeker and more stylish, drag coefficient dropped to 0.29. Inside, the new interior blandness with curves and all kinds of creature comfort buyers could dream of, seats with massaging and functions. However, the biggest must be the SLK-style retractable roof, which took a 16 seconds to open or close. the roof up, the cabin was impressively Meanwhile, a 20 percent boost to rigidity ensured the chassis to rock-solid even with the opened. You think it must be On the contrary, the R230 undercut its by 45 kg, thanks to the use of aluminum skins front fenders, doors, and boot lid), magnesium door panels and more steel in its construction.

Similar progress can be seen in its design. A new 4-link front replaced the old MacPherson struts to front-end grip and agility. ratio rack-and-pinion steering the old recirculating-ball to give more and directness. A new brake-by-wire system different brake pressure to wheels to optimize the performance of New Active Body Control automatically firmed up the suspension on wheels to limit body in corner. Consequently, the R230 sports-car-like handling and S-class-like comfort simultaneously.

Performance was not as as Porsche though. SL350 was by a 245 hp 3.7-liter 3-valve V6. SL500 over the 5-liter 3-valve V8 the old car. While 306 horsepower good in isolation, coupling to the kg roadster its performance was more adequate than impressive. mind, as performance chasers now opt for the new SL55 AMG. (Note: had acquired controlling stakes in AMG and integrating AMG models into its range) It employed a mega V8 with an IHI supercharger, producing 500 hp hp was claimed initially) and an astonishing 516 of torque. This enabled mph to be done in only 4.7 seconds, and let Motor und Sport to clock an 202 mph on Nardo test track, production car was regulated to 155 mph. it became a rival to Ferrari 550

As the standard car’s chassis was stiff enough and its ABC suspension was versatile, SL55 AMG needed few such as stronger brakes and a rear subframe to handle the load. It was a popular choice to buyers who wanted to taste performance without sacrificing or demanding advanced driving

SL63 AMG

In 2004, SL65 AMG was to the top of the tree. Its twin-turbo 6.0 V12 produced more power and torque at 612 hp and 738 respectively. American magazines able to time sub-4 for 0-60 sprint and just 8 seconds for 0-100 mph. In words, faster than 575 Maranello. However, it price was set as high as the Ferrari, while its burdened by the heavyweight engine, was as good as the Ferrari, or to less the cheaper SL55 AMG. It remained a minority choice in the years.

In 2006, the 3-valve V6/V8 family was finally with a new 4-valve family – 272 hp V6 and 388 hp 5.5-liter V8.

Even more changed in 2008. First of the whole SL range received a facelift including new headlamp and a wide front grille R129. Secondly, it got variable steering to sharpen response altering cruising refinement. the 3.5-liter V6 was enhanced to 316 hp. Lastly but not the SL55 AMG was replaced with AMG. Its 525 hp 6.2-liter naturally V8, codenamed M156, had a very character, trading the tremendous torque with a linear stronger top end and more delicious It was hardly faster than the old but the linear power let the driver to its chassis more easily. its new 7-speed MCT automatic gearbox, had conventional torque converter with a multi-plate clutch, faster gearshifts.

SL65 AMG Black series

To the R230 to bow out on a high, AMG introduced the and its fastest ever model in 2008. The SL65 AMG Black was radically different from SL65, as can be seen from its Its carbon-fiber body covered wider tracks and incorporated an aero package. The V12 was boosted to 670 hp by a of larger turbochargers. Moreover, 250 kg was by ditching the retractable roof replaced with an aluminum cage (which also strength) and a fixed carbon-fiber The cabin got lightweight carbon-fiber seats, but otherwise all luxury were kept. The Active Control was replaced with springs and dampers, but the latter fully adjustable like cars. Faster steering, brakes, massive tires and gearshift pattern completed the This car would have capable of topping 220 mph were it not to 199 mph. Its straight line was equally awesome. Unfortunately, in driving it was hampered by a series of turbo lag, slow strong understeer, harsh excessive width…

Perhaps it a step too far. The R230 SL, any of its predecessors, worked best as a luxury roadster. Focus on its and it would be very difficult to
