Objectives: SL65 AMG Black Series Intro At the conclusion of this course the participant will be able to: Identify the major changes on the SL65 BS vs SL65 Understand the unique service and maintenance needs Identify various component locations and networking Identify the drivetrain cooling components List the major changes to the drivetrain Highlight the body changes Identify the changes to the suspension, steering and braking systems Here are the topics that we will be covering and what we would like to focus on in our session today. Steve will start things off with a walkaround, not too detailed but enough to give you a good idea of what makes the SL65 Black Series so special and what differentiates it from the SL65. Then John will talk about some special Service Tips that you should be aware of, including some Roadside items, and general shop knowledge. Next we’ll move on to some important component locations, there are a number of systems differences on the SL65 BS. We’ll also look at some electrical and networking changes. Then we’ll look at the unique cooling system including the rear differential cooling setup. The engine and transmission will be next, followed by the body changes and then the suspension and brakes. Now, some introductory information and then our Walkaround. Department Titel of Presentation (CorpoS, 10pt), Date

Introduction to the SL65 AMG Black Series
2nd AMG Black Series car for US Total production 350 units 175 for the US Model Number R (P99) All MY 2009 US launch 1/22/09 MSRP $299,000 plus tax and destination No optional equipment Top speed 199 mph * secs Created by the AMG Performance Studio Assembled by HWA F1 Safety Car technology for the street Special Presentation Case with cover * Electronically Limited The SL65 Black Series is actually the 3rd Black Series car produced by AMG, it is the 2nd available in the US. The 1st was the SLK55 Black Series that was not offered here. The CLK63 Black Series was introduced in 2007 and now for 2009 we have the SL65 Black Series. We’ve been asked what the Black Series designation means. Obviously these are special cars, even more so than an AMG car already is. Black Series means very unique, formal, kind of like an American Express Black Card, ultra exclusive. Talking about exclusive, the total production for the SL65 BS will be only 350 cars for the entire world with 175 available for US customers. All will be 2009 models, there will be no more once production ends in early 2009.The SL65 BS uses the same model number as the SL65 ( ) it’s the option code P99 that denotes the Black Series. Official launch in the US is 22 Jan, MSRP is $299,000 plus destination and applicable taxes. SL65 BS cars are shipped in a container like the SLR Mclaren and will be delivered on their own transporter to the dealerships. Not all US dealers will be allocated an SL65 BS, check with Sales Management in your dealership about allocation information. There are no options offered for the SL65 BS, in fact the car does not have some equipment that is standard on the SL65, this includes Distronic, Parktronic, and Voice Control for the Telematics. Top speed is electronically limited to 199 mph, we don’t know the actual top speed of the car so don’t ask! Preliminary performance numbers include 0-60 in 3.6 secs. For more performance information, the latest issues of the major automotive publications have features on the SL65 BS. Like all Black Series cars the SL65 version was created by the AMG Performance Studio in Affalterbach which also creates the Safety Cars for the Formula One World Driving Championship, which of course was won by McLaren Mercedes driver Lewis Hamilton in The intent is to offer F1 Safety Car technology and performance for the street. The cars are mostly assembled by AMG partner HWA in Afflalterbach. HWA also builds and campaigns the AMG cars that run in the DTM or German Touring Car Championship, and has built other limited production AMG road cars not offered in the US. The SL65 BS is assembled on a race car- like assembly line, mostly by hand. The basic car is built at the SL plant in Bremen and then shipped to HWA where it is actually assembled and tested. All SL65 BS customers will receive with their car a special leather covered presentation box, that matches the interior of the car. Inside is a specially fitted AMG indoor car cover, a letter from MBUSA President and CEO Ernst Lieb, a matching signed engine build plate to the one on the engine and a special VIN tag. Lets take a look at the car. Department Titel of Presentation (CorpoS, 10pt), Date

SL65 AMG Black Series Walkaround- Front End
Most body work is Carbon Fiber Reinforced Plastic (CFRP) Hood with engine hot air outlets Front fenders with flares and vents - 5.5” wider than SL65 Front air dam in CFRP and composite with oversized air intakes for cooling for brakes, engine and turbo intercoolers Splitter is also CFRP, very low ground clearance! Only the headlights and mirrors are carried over from SL65 Distronic not available Unique hood release knob No front fog lights We’ll start our Walkaround at the front of the car with a front end that certainly doesn’t look like your typical 230 series SL. All of the body work that you can see here is Carbon Fiber Reinforced Plastic or CFRP. You might remember from our SLR McLaren training, that carbon fiber is 5 times stronger than steel and 1/3 rd the weight of aluminum. The SLR is made entirely of carbon fiber, in this case the SL65 BS still has a steel structure with carbon fiber body pieces. In this view the only things visible that are shared with the SL65 are the headlights and mirrors! The grille is changed as is the entire front fascia. There is a separate CFRP splitter under the nose to aid in front end downforce generation. Beware of the very low ground clearance of the SL65 BS, we’ll talk more about that in our Service Tips section. Note the big vents on the hood. It too is CFRP and those vents are entirely functional helping to exhaust the massive amount of heat created by the AMG Bi-turbo V-12 engine. The CFRP front fenders incorporate large flares to cover the wider tires and track, the SL65BS is almost 5.5” wider than an SL65. You won’t see any SL65 BS with the filled- in star in the grille evident of Distronic adaptive cruise control. As we’ve said, Distronic is not available. It does have standard MB Cruise Control. But the star in the grille does contain a little difference and that is the revised supplemental hood release now which pops out under the Star and is pulled to release the hood rather than pulling a lever further up under the hood itself. We’ll look at that next. You’ll also notice the large intakes in the front end, behind there is the oversized cooling module with coolers for engine, oil, a/c and the twin intercoolers for the turbos. There are large brake cooling inlets as well. We’ll talk more about the cooling module in a bit. These large intakes preclude the inclusion of front fog lights on the SL65 BS. The usual rear fog light is there on the driver’s side. Department Titel of Presentation (CorpoS, 10pt), Date

New Secondary Hood Release
SL65 AMG Black Series Walkaround- Front End New Secondary Hood Release Here’s the new secondary release for the hood. It pops out under the Star when the main release is pulled inside the car. Don’t use the little knob to lift the hood up, grab the hood itself. Even though its made of carbon fiber and is much lighter than the aluminum version on series SL’s, its still not light and the knob could be broken off if used to lift the entire weight of the hood. Lets move to the side… Once released from inside, then use pull knob to open Hood Department Titel of Presentation (CorpoS, 10pt), Date

SL65 AMG Black Series Walkaround - Side
Seven exterior colors available-consult DOG Fixed CFRP roof Revised roofline and windows for improved aerodynamics Integrated roll cage Doors carried over from SL65-aluminum and magnesium Large hot air outlets are visible in front CFRP fenders Largest tires and wheels ever put on a street AMG car Front tires are 265/35 x 19 Rear tires are 325/30 x 20 Dunlop Maxx Sport GT only approved tire No winter tire available There are 7 exterior colors available for the SL65 BS, consult the Dealer Ordering Guide for details. Starting with the roof, you might notice from our photo that the roof looks a little different from the SL65 and all the other R230 models. That’s because it is not a folding top. As befits the ultra high performance mission of this car the roof is made of carbon fiber and is fixed, and bonded in place. Its built around a roll cage structure much like a race car. Non of this is visible from inside the car, but the cross bar is visible inside the trunk behind the trim. The roll cage extends all the way down to the suspension towers in the rear and well into the B-Pillar near the doors. The rear side windows are fixed and are actually anchored to the roll bar. The rear window is recessed a little bit in the interest of managing the airflow to the rear spoiler. We’ll tell you more about that in a bit. The doors are carried over from other R230 SL’s and are of the usual aluminum and magnesium construction. The rear fenders with integral flares are steel and are obviously unique to the SL65 BS. You can also see here the large vents in the front fenders to help exhaust air from the front brakes. The wheels and tires are specially created for the SL65 BS. They are the largest ever offered on an AMG street car. The tires are sourced exclusively from Dunlop. There is no approved winter tire ,and tire chains cannot be fitted. The wheels are forged, which means that they are of the strongest and lightest possible construction. And from the specs you can see that they are of different sizes front to rear. The center caps are removable to expose the lug nuts with a special tool working with two little allen screws. 2 photos Department Titel of Presentation (CorpoS, 10pt), Date

SL65 AMG Black Series Walkaround- Rear End
CFRP deck lid Automatic rear spoiler (CFRP) Manual deployment with console switch Rear diffuser aids in creating downforce for high speed stability Aids cooling of rear differential Twin Sport Exhaust tips are unique to SL65 Black Series There’s more carbon fiber here too. The deck lid, spoiler and the diffuser under the bumper are CFRP. The rear bumper cover is urethane like most MB bumper covers. For the first time there is a deployable rear spoiler on an AMG car. More about the spoiler in a few minutes. Under the bumper you see a diffuser. This serves two purposes, both to do with managing airflow under the car. Like on F1 or AMG DTM C-Class racers, a diffuser helps to pull air under the car and directs it out the back of the car creating a swirl effect behind adding to the downforce produced by the rear spoiler. This device also helps the active cooling system for the rear differential. More about that to come as well. As we said this diffuser is made of carbon fiber, and has a replacement cost of over $17,000 so be careful with it! The twin sport exhaust tips are the largest ever offered on an AMG car. Now lets move to the interior. 2 photos Department Titel of Presentation (CorpoS, 10pt), Date

SL65 AMG Black Series Walkaround - Interior
Mostly SL65 interior with Carbon Fiber trim Unique 14.5 “ AMG Performance Studio Sport Steering Wheel Shift knob with “1 of 175” logo Unique seat pattern Full complement of airbags including side head/thorax, driver knee Start-stop button in place of Vario-roof switch One interior color available - Black AMG Black Series plaque on ash tray Black Series 220 mph speedometer The interior looks familiar from the SL65, but there are a couple of differences. The steering wheel is unique to the Black Series and comes from the Performance Studio it’s a little bit smaller and thicker than the other AMG steering wheels. There’s a special shift knob as well with 1 of 175 marked on it. The seats have a different pattern than the SL65, giving them a racier look. There are the usual number of SL airbags for a total of 5. There is only one interior color available- Black. The ashtray has a AMG Black Series badge. The speedometer is a special Black Series version with readings to 220 mph. That does it for our SL65 BS Walkaround, now John will tell us about some tips for Servicing and Maintenance. 3 photos Department Titel of Presentation (CorpoS, 10pt), Date

SL65 Black Series Service Needs
Raising Vehicle Always refer to Owner’s Manual before performing tire change or jacking up vehicle. Use provided wheel chocks Minimal ground clearance available for jack to slide under rocker For front wheel-Insert jack under door and slide forward to jack point Use caution when raising or lowering jack Wedge or plank will be needed for lift arms No spare tire provided As Steve already mentioned ground clearance for the SL65 BS can be a problem especially by the side of the road, so we will be talking about it quite a bit. Always consult the OM before any jacking or raising operation. The supplied scissor jack will not fit under the rocker panel if a front tire is flat. The jack will need to be inserted farther down the side under the door and then slid forward to meet up with the jack point under the car. Also take care not to impact the side of the car when using the ratchet tool for the jack. SL65 BS’ do not come with a spare tire. Most lift arms do not fit under the car either. But some of the newer type of two post lifts are a little lower profile and may provide more clearance. A wedge or wood plank will be needed to raise the car up enough the get the arms under. If your shop has an SLR two post lift this does offer a little better clearance, but caution will still be needed. … 2 top photos Department Titel of Presentation (CorpoS, 10pt), Date

Raising Vehicle As we said the SLR lift does provide for a little more clearance. Before lifting, the lifting mounts that are used for the SLR must be removed and correct lifting pads installed. Lets look at front end clearance… Department Titel of Presentation (CorpoS, 10pt), Date

Ground Clearance Minimal nose ground clearance Extreme caution needed with any approach to lift, ramp, driveway etc. Lower splitter is CFRP SL65 BS has very limited front end ground clearance. This can be an issue for flat beds, ramps, driveways, lifts, and alignment racks. The low point of the front end is the splitter under the front spoiler. The splitter is made of carbon fiber. There is an even lower point under the splitter, a little lip protects the oil cooler and hangs down a couple of inches. This is even more vulnerable than the splitter. Lip under splitter is even lower Department Titel of Presentation (CorpoS, 10pt), Date

Alignment Rack Issues When putting SL65 BS on an alignment rack there could be some clearance issues. The latest equipment in some of your dealerships are of the recessed design into the floor so this should not be an issue. But for older racks there is a problem with driving on to the lift. The car will need to be raised by about 3 inches to clear most rack ramps. A second person is needed for spotting the car onto the rack. Department Titel of Presentation (CorpoS, 10pt), Date

Alignment Rack Issues As the car moves up the ramp there can be additional clearance issues at the rocker panel. Department Titel of Presentation (CorpoS, 10pt), Date

SL65 Black Series Service Issues
Alignment Rack Issues Notice that there this not enough room for the nose of the car as it moves onto the turntables. The splitter will contact the end plates. Department Titel of Presentation (CorpoS, 10pt), Date

Alignment Rack Issues As the rack raises the car there is minimal clearance to the exhaust system. As you set up the jacks be aware of the possible contact points with the exhaust system. Department Titel of Presentation (CorpoS, 10pt), Date

Alignment Rack Issues There is a similar issue towards the rear with the rear diffusers and rear axle oil coolers. Again use caution as the car is raised. Lets move to the trunk… Department Titel of Presentation (CorpoS, 10pt), Date

Jump Start No SBC Single Battery in trunk No underhood connector Limited access to battery for cables Back here you’ll some obvious changes. Sensotronic Brake Control is not fitted to the SL65 BS, as it is on other R230’s, so it doesn’t need the starter back-up battery in the engine compartment. There is a single large battery located in the trunk just in front of the tool holder. The front trunk cover and the closeness of the tool holder makes access to the battery very limited. The tool holder does lift out, it is wedged in between the battery and the rear of the trunk. There is no jump start connector in the engine compartment, a jump start will have to be performed in the trunk. Battery access limited Department Titel of Presentation (CorpoS, 10pt), Date

Washer Fluid Reservoir Located in trunk Oversized Headlamps and Windshield Trunk cargo capacity 110 lbs Also in the trunk is a very large windshield/ headlight washer tank, assisting with weight distribution. It is very easy to service in this location. Along with the battery these are two relatively heavy components located in the trunk. In the interests of proper ride height, the trunk cargo capacity is limited to 110 lbs. Now lets take a more in depth look into some systems and we’ll start the cooling system. Department Titel of Presentation (CorpoS, 10pt), Date

SL65 Black Series Cooling and Aerodynamics
Front Cooling Module Bracket Cooling module Left /right Auxiliary cooler Condenser Engine coolant Air channel for cooler right Air channel for cooler left There’s a massive cooling structure in the front of the SL65 BS. The water radiator and the condenser are from the ML63 (164). The oil cooler which sits horizontally under the module in the nose of the car is a new HWA design as is the auxiliary cooler. There is a fuel cooler as well adapted from the SLR/Maybach. You can see the ducts for the front brake cooling also. In the driver’s side brake duct is the ambient air sensor.

The torque figure remains the same at 738, this number is electronically limited. Two photos Department Titel of Presentation (CorpoS, 10pt), Date

AdBlue Engine SL65 BS has a different air filter system from the SL65. It consists of a primary filter element and a secondary element behind it within an airbox on each side in front of the engine. There is a secondary air intake from the front brake ducts as well. Even though the primary filter may look like a K&N type, it is not serviceable and will need replacement. Now lets talk about the transmission. Secondary Filter Primary Filter Department Titel of Presentation (CorpoS, 10pt), Date

Manual-Comfort-Sport Button Transmission M1, M2 Manual Shift Programs w/paddles Keyless Go Start Stop Button 3-Stage ESP button The transmission in the SL65 BS is the NAG-V carried over from the SL65. The only major change is to the AMG Speedshift software which now provides for two manual shifting programs. There is a separate button from the usual C/S/M device. M1 shifting is 20% faster than in Sport Automatic and M2 shifting is 30% faster, all manual functions using the steering wheel shift paddles. There is also a throttle blip on downshift function as on the SL63 and C63. The SL65 BS also provides a unique series of upshift lights in the tachometer, just like a race car, that build in amber color as the rpm increase and then turn to red at 5000 rpm warning the driver to upshift before the 6200 rpm redline to avoid the fuel cutoff rev limiter. Here you can also see the Keyless Go Start Stop button which replaces the Vario Roof switch, and the button on the shifter surround that manually raises the rear spoiler. Like the C63 and SL63 the SL65 BS also includes the latest 3-stage AMG ESP. We’ll talk a little more about the 3-stage ESP in our braking section in a few minutes. Working our way down the drivetrain, lets look at the rear differential. 2 photos Button to raise rear spoiler Upshift lights Department Titel of Presentation (CorpoS, 10pt), Date

Rear Differential The differential is carried over largely from the SL65 with the same 2.82 final drive and 40% limited slip. But the HWA engineers have added a cooling system to the differential. Here you see the twin oil coolers on each side of the differential and the oil pump hanging just below the differential itself. As with all AMG vehicles with the limited slip differential, the oil must be changed between 1800 and 2000 miles to remove the break-in oil. The next differential oil service is at 30,000. There is a specific draining and filling procedure for this consult WIS for this information. 2 photos Twin Oil Coolers Cooler Oil Pump Department Titel of Presentation (CorpoS, 10pt), Date

Roof CFRP-Bonded to body
SL65 Black Series Body Rear Spoiler-CFRP Roof CFRP-Bonded to body Front Fenders CFRP Hood-CFRP Deck Lid-CFRP Rear Bumper Cover-Urethane Front Spoiler CFRP The SL65 BS has a body made up of a couple of different materials. Most of the body is Carbon Fiber, including front fenders, hood, roof, rear deck lid, and front and rear spoilers. As we’ve already seen the carbon roof is bonded to the body and includes an integral roll bar. The doors are standard SL materials, which means aluminum skin with magnesium inner shells. Again the rear fenders are steel. The rear bumper is polyurethane as on series production Mercedes-Benz models. The basic structure is steel as on the standard SL. And of course there’s the carbon fiber diffuser under the rear bumper. With all of this carbon bodywork, the fixed roof and lightweight suspension components the weight of the SL65 BS is about 250 lbs less than the SL65.

Here’s some more spoiler detail. The spoiler is powered by an extensive and sophisticated hydraulic system built into the deck lid. There is a reset procedure in WIS for the spoiler should it be needed. These two hydraulic rams are covered with a finishing panel and there is quite a bit of intrusion into the trunk when the lid is closed. Trunk capacity is limited in size and as already mentioned, has a cargo weight limit of 110 lbs.

SL65 Black Series Suspension, Steering and Brakes
New components- ABC gone, coil over race derived, lightweight Adjustability consult Owner’s Manual for default settings Steering Reduced steering lock due to larger tires and widened front track Brakes SBC replaced with ABR (hybrid) Lets take a look at the suspension, steering and braking systems. Active Body Control has been eliminated, the mission of the SL65 BS is one of high-performance above all else. ABC is an amazing system for relatively heavy high performance cars, it controls the body movements brilliantly, but it is a heavy system and does not offer the responsiveness and capabilities that this car’s level of performance demands. The race derived suspension system features adjustability functions to offer the driver even more adaptability. We’ll talk more about that. The steering hardware and settings are carried over from the SL65, but due to the much wider track and front wheels, and the revised suspension hardware and settings the usual Mercedes-Benz compact turning circle has been significantly reduced on the SL65 BS. The braking system is extensively modified as well with SBC replaced with a hybrid version of Adaptive Brake. More on that as well. Lets look at the suspension. Department Titel of Presentation (CorpoS, 10pt), Date

Front Suspension You’ll notice quite a difference to the suspension system on the SL65 BS. You can see here the coil over strut arrangement. Because ABC is gone there is now a need for anti-roll bars front and rear to control body roll. The next few slides show will go into some detail to show the adjustability of the suspension.

Notice how the anti-roll bar attaches to the suspension via a Heim joint, just like a race car. Here you can see the thread adjustments for the ride height, on the strut, The covering ring exposes the lower dampening adjustment which is for compression. Lets look at the ride height adjustment….

The vehicle default settings are the best combination for most driving situations including the race track. These adjustments as on a race car are for the experienced and sensitive driver who knows specifically how they like a car to handle and feel, and since many of our customers for this car have their own race technicians they might want to have this information. It is all included in the Owner’s Manual. It is unlikely that too many of our customers will even want to know about this. But we thought that as AMG professional technicians this is information that you would also want to have.

As we already mentioned the SL65 BS is not equipped with Sensotronic Brake Control. This means that there is extensive change to the braking system. It employs the Adaptive Brake functionality as on the revised 211 since Most of the hardware, brake discs, calipers etc are carried over from the SL65. This features the AMG compound system with aluminum center and cast iron disc on all 4 wheels. The front caliper is the latest 6 piston AMG aluminum device.

Front brake assemblies
SL65 Black Series Suspension, Steering and Brakes Front brake assemblies Brake cooling duct Here are the suspension and brake assemblies for the front. Around the front brake you’ll see a large carbon fiber brake cooling duct. Lets take a closer look at the brake cooling system… Department Titel of Presentation (CorpoS, 10pt), Date

Brake Cooling The brake cooling system consists of a series of hoses and ducts that bring cool air to the front brakes to assist in heat dissipation created by the extremely high performance capabiliites of this car. You’ll see the large diameter hose which is connected to the cooling ducts in the nose and then to the backing plate and the carbon fiber duct that surrounds most of the brake assembly. Now lets take a look at the hydraulic revisions to the braking system…3 photos Department Titel of Presentation (CorpoS, 10pt), Date

Brake system component changes
SL65 Black Series Suspension, Steering and Brakes Brake system component changes Hydraulic Unit SL65 Black Series is equipped with a brake booster derived from the SLK (R171). The physical appearance of the brake booster is a little bit different from the SLK, the two highlighted switches are not used. Even though the SLK does not use the Adaptive Brake system, the SL65 BS does making this a hybrid version of ABR. As we’ve already seen, on the other side of the engine compartment where the starter battery would be in a standard R230, sits the ESP hydraulic unit. Lets talk a little more about ESP in the SL65 BS. 3 photos Brake booster Department Titel of Presentation (CorpoS, 10pt), Date

ESP settings (Sport) ESP® stabilizes the vehicle only to a limited extent Engine output is less limited ETS will still apply the brakes ESP® continues to operate under hard braking Cruise Control not available For the skilled driver only As we know the SL65 BS has the latest AMG 3-stage ESP. The main advantage of the 3-stage ESP is that it gives the driver the opportunity to control the traction systems on the car to adapt to the style of driving that he would like to employ. With ESP set to Sport the parameters have been revised to allow for more oversteer or tail out cornering if the driver’s skill allows. The yellow ESP warning light comes on in the instrument cluster and the ESP Sport message appears in the multi-function screen. The stabilizing effect of ESP is limited, engine output (ASR) is limited to only allow for better launch traction out of a corner or drift. ETS will still intervene to control excessive wheel spin by applying the brakes. Cruise control will not function in ESP Sport, it will switch itself off if activated.

ESP settings (OFF) ESP® will not stabilize the vehicle Engine output is not limited ETS will still apply the brakes ESP® continues to operate under hard braking Cruise Control not available For track use only For the VERY skilled driver When setting to ESP OFF, an additional warning light will appear in the tachometer along with the yellow triangle and the ESP Off message in the Multi-Function screen. In this setting ESP will not offer any vehicle stabilization which means that extensive drift or oversteer angles are possible. ASR is also disabled which means that there will be no engine intervention to control wheel spin. ETS will still apply the brakes to control wheel spin, but with 661 hp and 738 lb/ft of torque the effect of ETS will be limited. Hard braking will return ESP functions including stability control to aid in cornering and emergency braking. Again cruise control is not available with ESP Off. ESP® OFF” is designed for driving on closed tracks when the vehicle’s natural oversteer and understeer characteristics are desired and requires a highly skilled and experienced driver able to handle these critical driving situations.
