Engineering

The future Mercedes-Benz SLR also points the way forward in the technology field. The body is built of fibre-reinforced composite materials and aluminum, providing not only exemplary crash resilience but also a weight saving of about 40% compared to conventional steel constructions.

Driving safety: braking by computer

Highly modern assistance systems on board the Vision SLR make driving easier and offer optimum driving safety in any situation. The new electro-hydraulic brake system (EHB) uses the sensors of the antilocking system (ABS) and the Electronic Stability Program (ESP) to calculate the brake pressure in each individual situation. Combining these assistance systems with the fibre-reinforced ceramic brake discs achieve considerable safety benefits when cornering or turning on smooth road surfaces.

Lighting technology

A new type of headlight system helps to adjust better to the prevailing road or traffic conditions in the dark. The headlights with adaptive light system and innovative high-power LEDs automatically follow the steering wheel movement and adapt to the particular driving situation improving the illumination of the road.

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.

Take a look at my earlier thread. The car is not going to be supercharged but twin turboed. It will be even FASTER than you thought. =)

 

I took these info from the mercedes-benz canadian website, so I think they probably know what they are talking about! Don't you?

 

I'm not a betting man, but you see,

the car is STILL advertised in north america as a supercharged v-8. JUST until the later part of this year, mercedes benz has scrapped the idea and are inputting the new twin turbo engines that are a part of all the 600s.

The news about that will trickle down later. Just like how all the new sclasses and cls are fitted w/new twin turbo engines.. because they put out more performance than the supercharnged ones do...MB is going twinturbo to knock out the murcielago and gt2.

 

Well, what do ya know, it is a supercharged V8 from the SL...

 

ok so i'm confused, is it a supercharged or twinturbo engine?

well doesn't matter.. its still plenty fast!

 

I guess we'll see for sure latest in September what the car exactly looks like and if the is super or turbo charged.

I latest info I posted earlier came straight from two german sources...

Wolfman

 

Never doubt the Germans...

 

"Man, they were nihilists, man. They kept saying they believed in nothing."

 

A friend of mine who ordered 2 SLRs was just informed last week that there has been NO final decision on the engine whatsoever. At this point it is not even sure how many cylinders it's going to get!

Hmmm...I guess some naysayers were saying that they knew (cuz of some Canada MB site or something) that the SLR was going to be a Supercharged V-8

I TOLD THEM about a YEAR AGO.. that my source indicated that they scrapped that idea for a twin turbo set up borrowed from the s-class and put in on the V-8.

But some people here wouldn't believe it and thought they had the latest information.

Well...hope you guys all pick up the latest May 2003 Road & Track and how they speak of the TWIN-TURBO set up for the SLR.

So...still think it's a superc harged 8???

 

Interesting: The final decistion regarding the engine has just been made a few weeks ago.

Ronald

 

The decision was made PUBLIC a few weeks ago. Road & Track needs a least a month before print so obviously it was more than a few weeks.

ALSO...It's through the european source that was saying Gordan Murray and his team scrapped the supercharged v-8 idea awhile back to be competitive in the horsepower wars.

U can refer to the old article I posted in the previous thread I listed in this thread.

Oh well..

Anyways..I'm not trying to be too serious..just teasing..but it's all funny how people will just stick to what they know even when it comes up short..

 

Last I heard, Gordon Murray was trying at all cost to avoid using turbo chargers, even if he had to use superchargers ("Anything, to avoid the turbos," I think he said). The RT article said that the engine is still a V8, but twin turbo-ed. At this point, I can say that nothing is for sure. It is highy l suspectible that they would develop a whole other engine V8TT, when they already ahve a V12 that is more than suitable to do the job. Going with eight cylinders, when the competition has at least 10, is plain uncompetitive. Even Gallardo, which is class below the Murcielago competitor of the SLR has 10 cylinders.

 

Whatever engine SLR uses, it's got to be a "better" engine than the 6.5 liter bi-turbo V-12 from AMG (603 hp that is, with over 700 pounds feet of torque [exactly 1000 newton meters that is]). The SLR has got to be the premium Mercedes Benz top performance car. Period!

I currently have the Road and Track May 2003 issue in front of me and it states that, "Power will come from a 5.4-liter V-8,..."

I can see why this SLR car is nolonger is going to be supercharged. It is my presumption that since Mercedes Benz saw the competition's horse power, bi-turbo charging maybe the only way to get more horsepower from a V-8. Besides Mercedes even had to "....put some of it's engineers onto the project." (Road and Track, pg.79, May 2003) And since Mercedes does not super charge <any> [correction: "MOST"] of it's current mainstream models, "It has to be remembered that this is a Mercedes first and a McLaren second,..." (Road and Track, pg. 79, May 2003)

Discredit my presumptions you may, I welcome them, but wouldn't you agree that if we had the same thinking, what a boring forum this would be.

"As might be expected from a project under Ron Dennis and Gordon Murray, the twin-turbo 550-bhp SLR is going to be a spectacular car." (Road and Track, pg.79, May 2003)

Of course the 1001 horse powered Bughatti Veyron at 186 mph in less than 14 seconds will be the fastest commercially main stream market brand with the highest top speed of 252 mph! These numbers of the Bughatti Veyron come from Road and Track magazine, pg.77, May 2003.

Any comments anybody, please?

 

Actually Mercedes supercharges several of its mainstream models, specifically the 200 and 230 Kompressor I4s in the SLK, CLK, C, and E. It is the turbocharging that is relatively new, at least for their gasoline engines.
