Mercedes Benz has confirmed the SLS AMG Gullwing will pack a 6.2L V8 with 571hp (420kW) and 479lb-ft (650Nm) of torque
Enlarge PhotoIn the lead up to its final unveiling, planned for later this year, Mercedes has released a ton of info on the car, including several images of actual prototypes and technical drawings. As the successor to the legendary SL Gullwing from the 1950s, the new SLS AMG will also feature gullwing doors but picks up a new aluminum spaceframe to provide an almost perfect front-to-rear weight distribution of 48-to-52%.
Powering the SLS will be a revised version of AMG’s now-familiar 6.2L V8 mated to an all-new 7-speed dual-clutch transmission mounted on the rear axle. Peak output will stand at 571hp (420kW) and 479lb-ft (650Nm) of torque. Changes to the engine include a new magnesium intake with eight separate velocity stacks, two electronically controlled throttle plates, a high-flow exhaust and a new dry-sump lubrication system.
The engine will be located up front but will be mounted behind the front axle for better weight distribution. The SLS’s final kerb weight will be around 1,620kg, and with the V8 engine it should be able to accelerate from 0-100km/h in 3.8 seconds and reach a top speed in excess of 315km/h.
As for the new dual-clutch gearbox, the unit was developed by AMG and boasts fast gear changes with no loss of tractive force. The driver has a choice of four different driving modes, ranging from comfortable to extremely sporty, as well as a ‘RACESTART’ function. The suspension set-up is equally advanced, with double wishbones and hub carriers made of lightweight forged aluminum. Stopping power comes from carbon-ceramic discs, and these are mounted within 19in light-alloy wheels.
The car’s dimensions have also been revealed, measuring in at 4.65m in length, 1.95m across and just 1.25m in height. The wheelbase stretches just 2.7m. Previous renderings give us a clue as to what the new car could look like, showing a vented bonnet and a new headlight design not seen on any previous Mercedes models.

Designers have gone with a distinctively retro look for the interior of the new SLS AMG
Enlarge PhotoPremium materials abound on every surface, with materials such as nappa leather, solid metal and (optional) carbon-fiber facings emphasizing the ‘custom-built’ nature of the car. Seating will be strictly limited to two.
The price of the SLS is expected to be roughly $300,000 with production numbers likely to fall between 3,000 and 5,000 units per year. This should see it compete nicely with cars like the Lamborghini Gallardo and Ferrari F430.

Sorry, I just don't know...
The return of the Gullwing appeals to me - and I am usually VERY septical about those new cars copying past glories.
But the headlights and the hood are pure Porsche to me and the shape, though a LOT more pleasing than the new SL class, is kind of vanilla (though maybe that's a good thing.
But the biggest thing I have against this car... does MB really need a new model? I mean, they must have about 50 of them out there. Why one more?
By cirquo #2, Posted: 5/1/2008
MB thinks they need competition for the new Alfa 8C's, the Ferrari Dinos and Maserati's.
By Alan #3, Posted: 5/1/2008
if this car is overpriced and overweight like the SLR it'll be a flop. Follow Audi and build a more light weight sports car like R8.
By DaveDav #4, Posted: 5/1/2008
anyone else think it maybe a supercharged AMG63 engine?
By Stephen #5, Posted: 5/1/2008
A 670 bhp 6.2 V8?! I thought Mercedes said they were done with the horsepower wars?
By admin #6, Posted: 5/1/2008
Stephen - that was probably just to trick BMW and Audi. :)
By chris #7, Posted: 5/1/2008
they said they were done with the HP wars,... as soon as the current big guns run their life cycle.
personally I believe this is why they're choosing to do a gullwing throwback at this exact moment in history. they have a decent architecture, and they may never have an engine quite as large and powerful as this. this is the last hoorah for cars like this.
after all, mercedes is making nothing but hydrogen cars as of 2015 right?
By Ad #8, Posted: 5/1/2008
i lke but i prefer the Audi R8 or the Audi RS6

That car in the video is a camo'd Dodge VIper.. It has identical taillights and front fender vents
By Matt #11, Posted: 5/1/2008
HaHA just read the article........
By chris #12, Posted: 5/1/2008
yeah matt; this car has been going through road testing for a while now,.. at least a year. always under viper skin. a lot of people started thinking the next gen viper would share the platform with the SL but then people realized that would be just plain rediculous.
I must admit, the idea of a merc viper is really interesting though.
By max abrams #13, Posted: 5/8/2008
dodge viper
By Moises #14, Posted: 6/26/2008
The car that is in the video is not a Merc SlC but the Dodge VIper
By Dandan #15, Posted: 7/30/2008
deffinately sounds supercharged...
By Gus #16, Posted: 7/31/2008
That door is interesting, but wouldn't you wind up hitting your head a lot?
By NaBUru38 #17, Posted: 8/2/2008
Alan's point is fair. Here's a list of some sporty Mercedes' weights:
o- SLK 55 AMG: 1575kg
o- CLK 63 AMG Coupé: 1755kg
o- CLK 63 AMG Cabrio: 1875kg
o- SL 63 AMG: 1970kg
o- SL 65 AMG: 2120kg
o- CL 63 AMG: 2085kg
o- CL 65 AMG: 2240kg
o- SLR McLaren: 1825kg
Too much fat in every case. Mercedes, use lightweight materiales, please?
By Carlos #18, Posted: 8/7/2008
Very nice retro design
By vaughan #19, Posted: 8/8/2008
is it just me or has merc gone and built a dodge viper? check the rear and sides...... clever merc!
By Dandan #20, Posted: 8/8/2008
what about the black edition CLK's? and the Black Edition SLK's? they're more high end light diggery sports cars for nutters.
Got to remember MB is probably trying to sell the Gullwing to rich people who probably have an S Class or a CL and want a play thing. They're keeping to their core competences which are luxury comfortable cars...even when they're sports cars.
By Gus #21, Posted: 8/19/2008
How would the convertible and gullwing doors work?
By www.mywheelsonwalls.com #22, Posted: 8/19/2008
Gus- Same way as they did on the old one. A very short door with a very tall sill.
http://www.silverstarrestorations.com/300SL.htm
By Gus #23, Posted: 8/19/2008
That is a cool link, but I still don't understand how that would work in a modern car?
By www.mywheelsonwalls.com #24, Posted: 8/20/2008
Gus- Maybe this will help. Although a different problem its still the same solution, that being you will need a stiff structure since there is no roof. In other words they use a much deeper sill to add strength and in this case to hide the doors. http://www.diseno-art.com/encyclopedia/vehicles/road/cars/bmw_z1.html
I would assume that the new Gullwing will have a monocoque/tub style chassis in stead of tubes/metal frame. So all they will do is use larger sills and cenventional hinged doors instead of gullwinged doors. The reason being they will already have large sills due to the fact that cutting into the roof for the gull wing doors creates a need to add strength else where. Ever wonder why the sills on the Ford GT are as big as they are?
By Gus #25, Posted: 8/20/2008
That makes sense now.
So the cabrio won't have special doors.
I always thought the doors on the Z1 were cool, but tough on safety...
By CK #26, Posted: 9/9/2008
To me this car still looks like a Viper with gullwing doors. Maybe they have taken the chassis form the Viper to adapt and modify it for a new car. The dimensions seem to fit this idea. At least they would have a chassis that can handle the power.
By Marco #27, Posted: 9/10/2008
580bhp only = =
By Oil Slick Rick #28, Posted: 9/10/2008
580 is alot but in recent times you can get that in an estate car 'only' is something you could use when talking about a 6.2.V8 hand built by one of the best builders of engines.
I personally think they should bring use the SLR's 55AMG engine or supercharge this 63AMG for more power and lots of torque.
I do realise I'm rambling now but; the new renderings have an MB grill on them, what happened to this being AMG only?
By mlevere1992 #29, Posted: 9/10/2008
Is it me or does the front end look a little like the Mazda RX8?
By james #30, Posted: 9/10/2008
that rendering is fantastic! i wasn't a big fan of the previous renderings as they reminded me too much of porches but this is something to really get excited about! i'm impressed
By DiecastHobbyUSA.com #31, Posted: 9/10/2008
I like the way the doors open up!
By Wizards Lore #32, Posted: 9/11/2008
is it just me or does this look quite good ?
im really glad that the overal style is of cruiser as opposed to brute in your face sports car...
the kind of car that James Bond would drive to the Casino...but woudl leave in an Aston Martin...it just seems to ooze class !
1950's Grace Kelly class !
Somebody really knows their old Benz's, to spot that the air vents are right out of the 70's.
I remember them from my parent's 450SL...
Man, I'm getting old!
did someone realize that i looks like a pontiac had a love child with an opel and was tagged mercedes benz AWFULL GERMANS WHERE'S UR MAGIC????!!!
I don't like what i see,it looks like a Dodge viper
unless it has about 500 pounds of camo
I guess we will see, i hope its cool.
Give the AMG V8 Di and twin turbo for this car
it looked like a viper... but man it sounds awesome, i hope it doesnt turn out like the pictures thats grose. im a bit anxious thinking if this car will do the old gullwing credit, the old car was amazing it was the best car in the world at the time and that is huuuge! to live up 2 i hope merc can do it.
i looks cool
I think they should just go all the way and creat a Enzo class supercar instead of another overweight grand tourer.

The orignial body cladding was acually from a Viper, early on
Mercedes Benz even went so far as to release a few official images of one of the prototype
Where can I find these?
Reminds me a little of the shape of the old BMW Z8, but much bigger.
I can't wait to see it unvieled.
ho ho one more time, I see the NISSAN GTR R35 headlights over here =))
More looking like it's going to be of a disappointment as what had happened to the MB/MacLaren SLR and Stirling Moss...
The car's got some bad propotions even with all those camoflauge.
That inside does not really give the impression of luxury, looks like cheap plastic everywhere -_-
Actually, its Suede(on the roof) leather(dashboard) and carbon fiber(center console), and think that's it.

The official prototypes in the shots you are reffering to were still covered in camo gear.
