I was able to take the SL65BS tech course and jotted down some differences between the two cars. These are all components on the SL65 BS. I know most of you probably know all this, but here's for some who don't

SL 65 Black Series

350 Units worldwide, only 175 in the US
No options
Top speed set to 199mph
F1 Safety car technology
Comes with a special leather convered case (matching interior) and an inside car cover
NO Distronic, ParkTRONIC, or Voice Control available

Exterior
Most of the body is constructed of Carbon Fiber Reinforced Plastic (CFRP)
Hood has two vents for heat extraction
Front fender flares are 5.5” wider than the SL65
Front air dam is CFRP with oversized air intakes for the brakes, engine, and intercoolers
Front splitter is CFRP
Headlights, mirrors, and doors are from the SL65
Unique hood release
pull knob under the star, use the entire hood to open, do not use just the pull knob
No fog lights
7 colors available
Fixed roof
Integrated roll cage with quarter windows attached to roll cage
Roof and windows revised for better aerodynamics
Largest tires ever on an AMG: 265/35/19 Fronts, 325/30/20 Rear, using Dunlop tires
Forged wheels, strongest available
CFRP deck lid
Automatic rising rear spoiler (raises at 75mph, lowers at 38mph, can manually raise up to 75mph)
Rear diffuser aides in downforce and cooling of rear differential ($17k to replace)
Aluminun doors
Rear fenders steel
Urethane rear bumper

Interior
Unique Steering wheel 14.5” diameter with flat bottom
1 color available (black)
Unique seat pattern
5 airbags, just like the SL65
Unique shift knob with “1 of 175” engraved
Start/Stop button replaces the convertible top button
BS plaque on the ash tray
BS 220mph speedometer

Engine
6.0L V12 bi-turbo
661hp/738lb-ft (electronically limited)
Revised turbos with larger impeller
Revised larger intercoolers

Transmission
5 speed from SL65
Manual/Sport/Comfort modes
3 stage ESP (On, Sport. Off)
Throttle blip function like on the SL63 and C63

Suspension
ABC gone, replaced by race devised coilovers (adjustability like the CLK63)
Rear differential cooler
Twin oil coolers with one cooling pump
SBC gone, replaced by hybrid ABR (adaptive brake)

 

The transmission is a 5-speed unit, not 7, unfortunately. Also, it is a 6.0L rather than a 6.5.

 

Nice write-up!!

Not to split hairs but the CLK GTR AMG had 295/35ZR18 and 345/35ZR18 tires. So it had wider tires...but obviously they were only 18's vs the SL65 BS's 20's. Does that make them the widest instead of the "largest"?

My apologies on the Tranny. It is the NagV722.6 carried over from the SL65, but it does have a new speedshift program, with 2 programs. M1 is 20% faster shifts and M2 is 30% faster.

 

What it is not is a roadster. It's hard to see how they are going to sell these for Ferrari scud money in this market. You can buy a nice 06 SL65 for 65 all day long, I did. I am not sure I can see it. I have not seen the torque curve on the motor but I doubt you could feel 63 hp. At best the difference is slight. So is it a body kit with a big price? I love cars especially bad a$$ ones but I don't know about this one. Just so you know it is not envy, I currently own a 997TT, F430, Z06 and an SL65.

 

Not to defend the SL65 BS pricing...but it is also 200+ lbs lighter than the SL65. Think of it this way...Ferrari charges $200K+ (assuming carbon ceramic brakes and F1 tranny) for the F430. Ferrari charges a $100K+ real world premium on the Scuderia...which also lowers the weight by 200+lbs and gives a 20hp bump. I am not saying that an SL65 BS is as desirable as a 430 Scuderia...but for the limited #'s being produced I can see MB enthusiasts with the cash snatching them up...even in this horrid economy.

I'd also like to see what the real world torque numbers are, as it says the torques is "electronically limited" to the 738lb/ft. Most likely due to the drivetrain, but I would bet that if they lifted the limiter, it would easily be above 800+lb/ft of torque

Automobile magazine put it on a Dynojet and got 573rwhp @ 5,300 rpm and 682 lb-ft @ 3,620 in 3rd gear. The torque is a little higher than most 65's would dyno..so the rating is a little light.

Tom

 

I think the stock Sl65 is capable of about 835 foot pounds of torque but they detune it because of the transmission. From the article listed above it does look like you get some hp and torque in the upper end. I quess at the end of the day none of this makes any sense and you just do what you want and can.

 

But Ferrari get their 20hp bump the hard way.

 

Hows that ? Becasue the Scud is n/a ?

 

The stock 65 engine generates 885 ft-lbs without the torque limiter. This is listed on the AMG site. All 65 engines, BS and non-BS, are limited to 738 ft-lbs (1,000 Nm) because that's the certification limit of the transmission.

The BS raises the torque curve's very broad "peak" (really a plateau due to the electronic limiter) to higher RPMs, generating a little more peak horsepower. As anyone with a Renntech or other tune knows, any 65 engine can generate 850+ ft-lb with nothing more than a flash, if you're willing to risk the transmission.

 

I somewhat agree that the die hard MB enthusiast would ****** one up even if it means that person has to live in a studio.

 

I have seen pics of the things done to the SL65 blk wooow is all i can say
It not just simple bump in hp..this thing drives completly differnt then any other benz (well not including the gtr) is what I have been told by people who have driven it.
Ride is much better then SLR 722 and so is the steering (less sensitive) but stil direct

and even with those big tires traction is stil lsot easily
