      Eisenmann is a factory supplier for AMG which often means they do not produce aftermarket exhausts for Mercedes AMG models. An exception in this instance has been made and Eisenmann has wrapped up its sport perforamnce C63 AMG exhaust prototype. The exhaust should be officially available soon and features 120x77 mm tips. A race exhaust system will also be available after the sport. As always, the exhaust will be available for purchase through BenzBoost premier vendor IND who is the official North American Distributer for Eisenmann: www.eisenmann-na.com ...

      When we posted the dyno numbers for the M157 Performance Package twin turbo we were blown away. Over 500 horsepower at the wheels? Over 600 wheel torque? Ridiculous power indeed. The question was how it would transfer to the dragstrip and we have an answer. Insideline ran the car hitting 12.3@116. We expected a bit more out of it but putting the time in context with the S65 AMG that they tested to 12.6@115 and you see the new S63 AMG is actually quicker and faster than the S65 AMG. Remember, this is a 5,000 pound car. ...

      We reported not too long ago that the M156 was rumored to be confirmed for the Black Series C-Class. With this latest round of spy photos M157 twin turbo V8 rumors have started up again due to the sounds heard from the car when testing. Could it just be a photographer imagining things? Sure, as all signs are pointing to the M156 right now. It could be that Mercedes hasn't made their own minds up yet. ...

      The M156 has received plenty of accolades over the years, deservedly so. However, its run in the International Engine of the Year awards has come to an end in 2011. The M156 won the Best Performance Engine of the Year category for the past 2 years (2009, 2010) as well as the best engine over 4.0 liters of displacement taking the place of the BMW S85 V10. The Ferrari 4.5 liter V8 from the 458 Italia has knocked the M156 out of both spots. It was a good run and 63 AMG owners with the motor should be proud that it took an engine in a car over $250k to beat it out. ...

      This is the 2030 Mercedes Aria by Slavche Tanevski. A student at the Munich Univeristy of Applied Sciences, this design was his bachelor's thesis and we are guessing he passed. He was under the direct instruction of Mercedes designers, talk about a tough crowd to impress. It is also imagined as an all electric design and it would seem by 2030 Mercedes expects most of its cars to be electrics. Check it out, it's just a dream, but a great one. ...

      The 551 whp dyno graph posted below is from a CLK63 Black Series belonging to BenzBoost member Ecampbell. He was kind enough to share his graph after some controversy resulting from a 573 whp graph that we posted for a similar Weistec supercharger setup. The graph you see here is the result of a claimed 5.5-6.0 psi with aftermarket Hennessey headers and an Evosport exhaust. Very strong results for 91 octane pump gas. ...

      We finally have some test numbers for the new M278 4.7 liter direct injected twin turbo V8 that will be going into all the new Mercedes 550 models. In the very heavy CL550 at California Speedway (a notoriously slow drag strip) Edmunds Insidline was able to hit a 12.8@109 on street tires. This is in an almost 4700 pound car. What this means is with this motor in the E class the new E550 is going to be putting up acceleration numbers that won't be too far off the previous generation E63 AMG with the M156 naturally aspirated V8. The new E550 is going to be a very fast car and this bodes well for the new E63 AMG. The new CL550 basically matches the elapsed time of the previous naturally aspirated CL63 AMG and is a few MPH off its trap speed. ...

      Bruno Spengler conitnued his strong racing for Mercedes finishing in second place after taking the pole in qualifying. Spengler won the first of the season but was not able to hold off Mike Rockenfeller in his Audi. Audi took the 1st, 3rd, and 5th spots with Mercedes taking 2nd and 4th out of the top 5. The next race is in 21 days in Austria. ...

      This is unconfirmed as official but several sites are reporting that Mercedes intends to wind down the G-wagon production with a bang. Most details are coming from Autoblog.nl who reports a 600 horsepower version of the G-class with the M275 twin turbo V12 is coming. They also report that the price would be around $300,000 which makes absolutely no sense. Yes, a twin turbo V12 G-wagon is cool, but for $300k there are a lot of other things to purchase where that kind of money would be better spent. The price is likely off, if not the entire story. ...

      Here we have an R171 SLK 55 AMG that has been tuned by Eurocharged. The SLK55 has a 5.4 liter naturally aspirated V8 that is pretty potent to begin with offering 355 horsepower. Eurocharged is able to raise that by 19 horsepower at the wheels. The graphs show gains over the baseline throughout the entire curve. The tuning is very smooth and the they are able to get gains without aggressively leaning the car out. Just smooth, solid tuning across the powerband, well done. ...

      Autoscoops.be is reporting that it has the exclusive leaked images of the production A-class. You will notice that it differs a bit from the concept which is not really a shock as it is toned down for production. The design is almost a bit boring compared to the hot hatch coupe concept. It is also reported to be front wheel drive which is disappointing to say the least. ...

      We know you have been waiting for dyno numbers for the M157 with baited breath just like we have. Now, the sleepless nights can finally come to an end. Insideline dyno tested the S63 AMG featuring the new twin turbo V8 powerplant with the optional Performance Package and all we have to say is: TORQUE, A LOT OF TORQUE. Wow, over 600 pound-feet at the wheels. They also overlaid the graph with the M159 naturally aspirated v8 out of the Mercedes SLS AMG and once you see the curves compared we don't think you or anyone else is going to miss the M156/M159 motor very much. ...

      The SLK isn't the manliest car to begin with but Piecha Design has managed to add some aggression to the new R172 SLK. From the quad exhaust to the front lip this car does a good job previewing what the AMG version may look like. If you are wondering why you see the sideskirts lightning up it is because there is an LED light option for the sideskirs. Yes, it seems tuners aren't satisfied with just sticking LED's in the front bumper but now are trying to put them anywhere they can. Price and part list is below. ...

      Here is the Carlsson offering for the new E-class convertible. Pretty standard fair as expected with the usual body pieces. Carlsson offers a front lip, sideskirts, diffuser, and trunk spoiler. Carlsson exhaust tips are included with their exhaust offering. An ECU upgrade is available for the diesel model thus far (which is not available in the USA) with others coming shortly. Carlsson wheels and lowering springs round out the overall well done package which we like although we could do without the huge Carlsson grille badge. ...

      We would like to thank BenzBoost user 220S for helping us obtain the dealer order guide. There are some very interesting things in the dealer document namely that the E550 will only come in 4Matic. No rear wheel drive E550? Yes, sounds very odd but look at the document yourself. The guide also confirms that the W212 E63 wagon with the M157 twin turbo motor will be coming to the USA. Very cool, but we still do not understand why the decision was made for the E550 to be all wheel drive only. ...
