i dont know if these are the proper specs but they are taken off mercedes web site.

Torque of 531 lb-ft for the sprint from 0 to 100 km/h in 4.2 seconds

The prominent long hood of the SLR conceals a powerful V-8 engine with a cubic capacity of 5.5 litres. Thanks to the compressor-type supercharger and water-to-air intercooler, the 8-cylinder engine develops 557 hp / 410 kW and provides a maximum torque of 531 lb-ft at 4000 rpm. This power unit accelerates the high-performance sports car from standstill to 100km/h in only 4.2 seconds with a top speed of 320 km/h.

not bad timing in the 0-62mph
it still has an amazing engine.

 

The SLR letter sent to dealers a few weeks ago says to expect 600 HP or more and a weight of 1400 kg. That would yield a 0-100 km time of well under 4 seconds. 3.4 seconds would be my guess.

 

it ll be A LOT faster then!...600+ hp on a body that weighs about 1400kg?...that car sure is going to have some astounding numbers

 

These spect look like the specs of the SL55...
correct me if i'm wrong.

 

i dont thnk its for the sl55...the sl amg has 493hp, which is a difference from the above specs.

 

These are probably specs from SL55's crank? If anything, the rear wheel is dynoed (i can't seem to find the link) at around 494hp to up 501hp.

 

Hmm,

Guess we all have to wait for the official numbers from MB..

 

the specs i posted come from mercedes canada website. i suppose they could be wrong but if i had to believe anything i have seen to date it would be from mercedes site directly. you can go to the link below and then go to models, upcoming, vision slr and engineering. you will see them there. although it will be an awesome care and very exclusive i am so happy with my sl55 i couldnt see spending that extra money.

last I heard about the SLR was that it would have over 600hp... no details though

 

I have personally seen and read the carbon fibre and aluminum brochure and accompanying official letter from MB describing the SLR in detail. Also included was a customer order contract (which I signed). These arrived at my dealer 3 weeks ago. This is more recent information than posted on the MB web site. The letter said to expect more than 600 HP and a weight of 1400 KG. The specs. wiil be finalized in time for Geneva in September, when the car will be officially launched. There is no question in my mind that they are attempting to outgun the Enzo and Carrera GT. We'll have to wait and see.

"Mercedes SLR latest info
According to Autocar, SLR will be powered by a 6.0-litre twin-turbo V8, not the 5.5-litre supercharged V8 specified in the show car. This lifts maximum power from 557 to 580hp, exactly the same as the V12 of Lamborghini Murcielago. IMO the switch to twin-turbo might be a response to the competition from Lamborghini, as the Mercedes will be priced higher than the bull. The turbocharged V8, however, will produce significantly more torque than the higher-revving Lamborghini V12.

The chassis, combining carbon fiber tub and aluminium spaceframes, is nearly finalized. Development chief Gordon Murray has already achieved an excellent weight distribution of 47.5:52.5 front to rear in the prototype, just half a point away from his ideal target 47:53. This is contributed by the lightweight Mercedes V8 which is also short enough to be placed behind the front axle. Having slightly more weight at the rear wheels should provide maximum grip to the rear-drive supercar. BTW, Ferrari is also trying to shift more weight towards the rear for its forthcoming replacement to 575M. By then, no one will call 50:50 as perfect distribution anymore.

Gordon Murray is also optimistic to achieve a kerb weight of a little more than 1400kg, giving the Mercedes an advantage of nearly 300kg compare with Lamborghini and Ferrari 575M.

There are some surprising information about the SLR. Firstly, it will use conventional steel brakes instead of the ceramic brakes once fitted to the limited edition CL55AMG F1. This might imply the ceramic brake is not perfect yet. However, the SLR will employ SBC drive-by-wire brake control like SL and E-class.

Another surprise is that SLR will drive through a 5-speed automatic rather than 6-speed. So far, Mercedes insists to use only its own automatic gearbox rather than outsourcing from ZF which has a superb 6-speeder. It is known that Mercedes is also developing a 6-speed automatic, but it is at least 18 months away, therefore the SLR will not be equipped with 6-speeder, at least for the early production cars. Having 1 less ratio will affect its acceleration. However, with so much power and torque and a relatively lightweight body, it is believed the Mercedes can easily sprint from 0 to 60mph in less than 3.6 seconds. "

 

The world is coming to an end, and i'm loving every second of it!
