      Insideline has tested the new SLK350 with the M276 3.5 liter direct injected and naturally aspirated V6. The motor is rated at 302 horsepower and 273 pound-feet of torque. The car ran a respectable 13.8@101 in the 1/4 mile although we expected a little more out of this new motor. The previous generation SLK350 with just 268 horsepower was tested by Car and Driver at 13.8@103 making the performance numbers for the new car and new motor a little disappointing. The new car is about 150 pounds heavier but the new motor should have easily offset that.

      This is a very interesting bit of news for motorsport fans and a bit of a sad one for Mercedes DTM fans. As you all know, BMW will be racing in DTM next year. Many wondered how they would do in their first season back after an absence of two decades. Well, they certainly will be poised to do well by taking the current leader in the DTM driver standings from Mercedes. This move strengthens BMW and hurts Mercedes shifting the balance of power already for the 2012 season.

      This story is kind of odd for a couple reasons. First of all, the idea of a high performance G-Wagon designed for paved roads goes against the intended purpose of the vehicle. Secondly, why is the M156 the motor that will be chosen when Mercedes is phasing it out on their own replacing it with the twin turbo M157 5.5 liter V8? Beats us, but Mercedes may be planning to send both the motor and the G-Wagon off in style. The vehicle pictured below may also be a G65 AMG with a V12 twin turbo. We will all just have to sit and wait to find out what Mercedes has up their sleeve at Frankfurt.

      The Belgium GP has always thrilled everyone and this years race solidifies that notion. From Senna's crash at the beginning to Schumacher starting last and finishing 5th. Mercedes GP started strong with Rosberg moving from 5th place to overtake Vettel and take 1st place at the end of Spa's straight away and last place Schumacher finished the first lap in 15th place. Like every race though, Mercedes GP began to lose it's overall race pace to Redbull and Mclaren and saw Rosberg fall to 5th place. With 3 laps left, Michael Schumacher with soft tires and DRS stormed past Rosberg on the harder compound on the straight away to claim 5th place.

      Finally after a long month break, F1 returns to one of the if not the best circuit in racing: Spa-Francorchamps. The mix of long straights and fast corners, combined with a picturesque setting and notoriously changeable weather keeps it at the top of both drivers and spectators favourite circuits. Part of the magic of Spa is that it is known and respected as one of the most challenging in the world, and to prove that fact only six drivers have managed to win the Belgian Grand Prix at Spa more than twice: Juan Manual Fangio and Damon Hill both have three wins to their name, Jim Clark and Kimi Raikkonen managed one better with four wins and Ayrton Senna won the race five times. The undisputed Spa master though, is Michael Schumacher who has won a record six times. This race is especially sepecial for him. Spa marks Michael's 20th year in F1 having made his debut in the 1991 Belguim GP.

      Well, here it is, the new B-class. Not exactly the most anticipated model for performance enthusiasts but it is a new Mercedes vehicle. The styling inside and out is fairly nice but it does not really matter as we will not be getting it here in the USA. Car is built for efficiency anyway with a .26 drag coefficient and 122/156 horsepower 4 cylinder motors available. Would be nice to get this over to the US, or make a version with a V8, but for now we are not shedding tears over this car.

      Here is a new widebody option for W204 C63 AMG cars. A very well priced and attractive option considering the pricing will be somewhere in the $5000 range. The body kit is all steel, no carbon reinforced plastic or anything like that. One can go to up to 355 rear tires in back. Considering what some of the C63 AMG's are putting out power wise, being able to go that wide should mitigate some traction issues. In order to get this kit one has to send their car to Orlando, Florida.

      This past weekend BenzBoost members ecampbell and jrcart went for a test and tune at the Las Vegas Motor Speedway dragstrip. BenzBoost was in attendance thanks to a generous invitation from ecampbell and Weistec was also present with Steve Atneyel and Michael Weiss. We were a bit a surprised that Earl (ecampbell) and Jim (jrcart) wanted to run in the middle of the summer with insanely hot temps in Vegas. When driving in, the temperature readout in our car showed 108 degrees at 6:15 PM. Not exactly weather for setting records.

      Here it finally is folks, the new 2012 SLK55 AMG. The car has a 422 horsepower 5.5 liter V8 which is naturally aspirated. The motor also features cylinder deactivation technology. It would seem Mercedes did not want the SLK stepping on any of its big brothers toes so it developed this new V8 specifically for the SLK55 . Expect more details and higher resolution photos after the Frankfurt Auto Show where the SLK55 will be officially revealed but for now enjoy this first set of photos.

      Got my baseline dyno last week and went and got my tune from Eurorev/Singh autosport on fri. Car feels great..went on few runs up to 165mph and it was pulling like a freight train. I'm very happy with the tune and it drives like stock except when you stomp on it. Been modding cars long enough to know it was best to take to independent dyno shop and i'm very pleased with result. Coming from PTT, W212 E63, C 63 and E60 M5..this is by far the best and fastest car i've own! BTW this same dyno did a 2012 S63 with Performance Pkg and it was 537 rwhp and 611 tq which was published on Insideline.com. This show you the potential of the M157.

      There were some alarming reports earlier this year that Michael Schumacher would perhaps not return to finish out his contract due to his "heart" not being into it any longer. Well, Schumacher ended the speculation by confirming he will be coming back next year which is his final year under contract. What is interesting is that Mercedes GP president Ross Brawn is the one who hinted at issues with Schumacher and Mercedes-Petronas stating Schumacher's future with the team would be evaluated later this year. That must have put pressure on Schumacher who decided during the season to return.

      This is the car that has been getting a lot of attention due to the owners erratic behavior. A fauly crank position sensor caused some issues but that has since been resolved. The vehicle put down an eye opening 630 whp and the owner describes it as being 'too powerful' as if there was such a thing. This build just goes to show having some trust in reputable vendors and tuners to resolve issues goes a long way as does a bit of patience/class. Well done Weistec and ACG!

      These are the same pulleys that are used on all the Weistec supercharger kits. These CNC machined aluminum belt idlers are also available for all M156 based cars not just those with the supercharger kit. The factory Mercedes pulleys are plastic and have been known to have problems. For modified or even stock vehicles this billet pulley is a good solution. It is a direct bolt in replacement, $299.

      Suspension systems that are able to raise the nose of a car at the push of a button are getting popular. Namely in the performance car scene because performance enthusiasts like their cars low to the ground for handling and styling. Problems arise when trying to enter steep driveways or go over speed bumps but Carlsson has SLS owners covered. This system can raise the car at both ends up to 40mm and do so at speeds of up to 50 MPH. Very useful and likely very expensive.
