Tråd: Mercedes-Benz SLS AMG Black Series første drev gennemgang

Denne 622bhp sledgehammer blander luksus og betagende præstation, men er det værd at 230,000? Dette er velsagtens den mest driver-fokuserede Mercedes-Benz road bil nogensinde: SLS AMG Black Series. SLS AMG Black Series kiggede aggressive nok dækket i forklædning, når vi Red i det sent sidste år, men som det sidder i pitlane på Paul Ricard-banen i Frankrig, motoren at dreje over med en klumpet idle, du får en fornemmelse af at alle mangler er race numre knyttet til dens karrosseri. Dens helt sikkert langt fra standard SLS GT kørte vi et par måneder tilbage. Ud over den dybe nye forreste kofanger, med integreret kulfiber splitter og forreste vinger, der er blevet udvidet med 13mm, er det lang, kurvede kulfiber motorhjelm med integreret luftkanal, der virkelig adskiller det fra hinanden. Yderligere tilbage, der er dybt nye karme med kølekanaler for de bageste bremser, bageste vinger, der strækker sig ud af en ekstra 26mm og en reprofiled bageste kofanger med en mere omfattende diffuser. AMGs nyeste Black Series model leveres også med en valgfri aerodynamiske pakke, der har supplerende winglets på de ydre hjørner af den forreste kofanger for forbedret afkøling af de forbremser, samt en fremtrædende kulfiber bagskærmen på bootlid i stedet for det standard løftbare. SLS sort serien har haft stor gavn af eksistensen af SLS GT3 racerbil og SLS elektriske drev. Forskellige lightweight komponenter og byggeri løsninger fra både tillader det at ramme skalaerne 70kg nedenfor for SLS GT, 1550 kg. Nøglen blandt udvikling bragt til modellens Black Series er en ny kulfiber drejningsmoment tube, hvorigennem propshaft kører. Samt at det er meget lettere end standard aluminium arrangement, hævdes det også at være betydeligt mere stive for større strukturelle integritet. Skot bag sæderne er nu også fremstillet af kulfiber, igen øge den samlede stivhed. Den virkelige stolthed, dog er motoren. De naturlig indsugning 6. 2-liters V8 vedtager utallige detaljer ændringer, herunder reviderede ventil gear med ændrede cam geometri og revideret spand Ventilløfterne, en ny indsugningssystem, omkonfigureret remtræk, optimeret krank forsamling og en helt ny vand og olie kølesystem. Power øger af 59bhp til 622bhp, som overtrumfer en Porsche 911 GT2 RS. Maksimale effekt ankommer 600 rpm yderligere op rev rækkevidde på 8000 rpm. Drejningsmoment er blevet reduceret med 11lb ft interesse for low-end sporbarhed, vil fra 479lb ft på 4750 rpm 468lb ft på 5500 rpm.

This 622bhp sledgehammer blends luxury and breathtaking performance, but is it worth 230,000? This is arguably the most driver-focused Mercedes-Benz road car ever: the SLS AMG Black Series. The SLS AMG Black Series looked aggressive enough covered in disguise when we rode in it late last year, but as it sits in the pitlane at the Paul Ricard circuit in France, its engine turning over with a lumpy idle, you get the feeling that all it lacks are race numbers attached to its bodywork. Its certainly a long way from the standard SLS GT we drove a couple of months back. Beyond the deep new front bumper, with integral carbonfibre splitter, and front wings that have been widened by 13mm, it is the long, contoured carbonfibre bonnet with integral air duct that really sets it apart. Further back, there are deep new sills with cooling ducts for the rear brakes, rear wings that extend out by an extra 26mm and a reprofiled rear bumper with a more substantial diffuser. AMGs latest Black Series model also comes with an optional aerodynamic package that has additional winglets on the outer corners of the front bumper for improved cooling of the front brakes, as well as a prominent carbonfibre rear wing on the bootlid in place of the standard retractable one. The SLS Black Series has benefited greatly from the existence of the SLS GT3 race car and SLS Electric Drive. Various lightweight components and construction solutions from both allow it to hit the scales 70kg below that of the SLS GT, at 1550kg. Key among the developments brought to the Black Series model is a new carbonfibre torque tube, through which the propshaft runs. As well as being much lighter than the standard aluminium arrangement, it is also claimed to be significantly more rigid for greater structural integrity. The bulkhead behind the seats is also now made of carbonfibre, again increasing the overall stiffness. The real showpiece, though, is the engine. The naturally aspirated 6. 2-litre V8 adopts myriad detail changes, including revised valve gear with altered cam geometry and revised bucket tappets, a new intake system, reconfigured belt drive, optimised crank assembly and an entirely new water and oil cooling system. Power increases by 59bhp to 622bhp, which trumps a Porsche 911 GT2 RS. Maximum power arrives 600rpm further up the rev range, at 8000rpm. Torque has been reduced by 11lb ft in the interests of low-end tractability, going from 479lb ft at 4750rpm to 468lb ft at 5500rpm.
