With the demise of the Mercedes SLK 55 AMG, Mercedes says goodbye in final form to the atmospheric

There are a couple of data that will make you feel old. The only engine’s maximum torque of across the range BMW is the twin of the bike that extends the autonomy of the i3. Although Audi still maintains some air of high-performance in the portfolio, is the only German premium in that battle. With the launch of the Mercedes SLC, Mercedes says goodbye to the naturally aspirated engines. I refer specifically to the Mercedes SLK 55 AMG, whose V8 engine maximum power just to be removed by a twin-turbo V6 with less power. What times these.

Mercedes SLK 55 AMG was a very sporty atypical

SLK 55 AMG always equipped engines 5.5-liter V8 atmospheric. An approximation muscle car most interesting.

When Mercedes launched its first version AMG SLK – about 15 years ago, neither more nor less – equipped with a 3.2 V6 with three valves per cylinder, supercharged by a compressor, with the developing 354 HP. It was a time in which AMG experimented constantly with the V6 and even with cycle engines Diesel, you can ride in the C 30 CDI AMG. That V6 supercharged was a propellant radical, created solely for a model AMG. Only ride during its first generation, since that would be shortly after replaced by V8 power.

The second generation of the Mercedes SLK was inspired by the SLR for his design, with that nose so sharp and pointed. To this day I still think that it was the generation more beautiful, although the interior was somewhat bland. The version of high-performance happened to be called SLK 55 AMG, and although its power output hardly changed, yes changed greatly its origin. Mercedes abandoned the V6 and installed a huge atmospheric V8 of 5,5 liters and three valves per cylinder in their place. A motor with only 6 BHP more than the SLK 32 AMG.

A roadster little larger than a subcompact with a V8 under the hood and rear wheel drive. Really unique.

SLK 55 AMG had tons of torque and despite being 80 kg heavier than its predecessor, it was faster in all the records. Really, the SLK 55 AMG has always been a unique car. Your approach is very similar to that of a muscle car: riding a giant atmospheric V8 in a body that did not go to the 4.10 metres. Definitely, a car that no other manufacturer dared to build. Mercedes kept very much alive the flame of the V8 in Europe, although they were cars intended in large part to the united States.

Ode to the last the maximum torque of the Mercedes

Mercedes SLK 55 AMG current – now in its third generation – is a car very similar to the second generation in approach and execution. Your engine M152 is a version atmospheric M157, engines V8 Biturbo of 5.5-liters that have been mounted, and still riding some AMG, as for example the CLS 63 AMG. Although the size of the SLK 55 AMG only grew to 4,15 metres, its power grew up up to 421 CV. All passed the train back through an automatic gearbox seven relations, making possible features amazing.

Mercedes SLK 55 AMG it was the last Mercedes with the engine’s maximum torque was left on the range. As you hear it.

Talk of a 0 to 100 km/h in just 4.6 seconds. Thanks to a technology of partial deactivation of the cylinders, I got to approve an average consumption of 8.4 l/100 km why was that Mercedes developed a version of atmospheric M157 for this application so unique? The platform of the Mercedes SLK 55 AMG did not leave site to install the V8 Biturbo AMG more powerful. A SLK 63 AMG with close to 500 HP of power it would have been a spectacle worth seeing, and a power to all lights, excessive for the small roadster.

The V8’s maximum torque high in the front gave it a single character, and a sound escape sensational, even though it wasn’t the car more dynamic, or agile in its segment: an Audi TT-RS was faster in all the records, with three-cylinder and 80 HP less. With the launch of the Mercedes SLC – a face wash with the one that renamed the SLK – aspirated V8 AMG says a good-bye final, and also say the naturally aspirated engines in the entire range Mercedes. not a single Mercedes comes out already from the factory without turbos under the hood.

is There hope for the Mercedes-AMG SLC 43?

We deserved a Mercedes SLK 55 AMG more radical and more powerful, as a farewell worthy of the atmospheric conditions.

Although call AMG SLC 43, under the hood we find a 3.0 V6 double turbo. Its power decreases from 421 HP to 367 HP. Your torque is also lower, with 520 Nm between 2,000 rpm and 4,200 rpm, 20 Nm less than the atmospheric V8. We continue: its 0 to 100 km/h is 0.1 seconds higher, with a record of 4.7 seconds. Its average consumption approved it is only 0.6 l/100 km less than the V8. Your weight will be slightly lower, but we do not have the data of weight in these moments.


however, what hurts me most, is that this is not an engine AMG “pata negra”. It is not a propeller manufactured in Affalterbach, is the same V6 with two turbos mounted cars like the Mercedes GL 400 or the Mercedes C 450 AMG. A engine tested, powerful and wise… but a generalist. Where is the flat iron with the name of the technician that assembled the engine? Where was the philosophy “one man, one engine” other AMG? The range AMG the roadster loses character, many kits aesthetic and sound to channel through the speakers.

Not everything is bad in this change of generations: the Mercedes-AMG SLC 43 premiered suspension adaptive sports, an automatic transmission 9 relationships as quickly and an interesting limited-slip differential, mechanical rear, not an electronic simulation of the same. I don’t doubt the effectiveness of the combination of twin-turbo V6 and automatic gearbox, but take away a atmospheric V8 in this way is like giving a toy to a child and take it off when you are enjoying it. The Mercedes-AMG SLC 43 is much more conventional.
