"         There is a battle of the ultra-exotic convertibles underway, and the Mercedes-Benz SLS AMG Black Series Roadster appears to be the latest model getting ready to join the fray. We&amp;#039;ve reported on prototypes of the Black Series Coupe being spotted while testing, but these artist illustrations provide the first peek at what the ultimate SLS AMG could look like in Roadster format. Larger air intakes and vents along the sides, just aft of each front wheel, provide additional cooling to the 6.2-liter V-8 lurking under the hood. The engine is expected to produce 622 bhp and 468 lb.-ft. of torque. That&amp;#039;s a noticeable jump from the 563 bhp offered in the standard SLS AMG, though still down on the 700-bhp V-12 you&amp;#039;ll find in the mid-engine Lamborghini Aventador convertible.           A Diet Rich in Carbon Fiber   Compared to the stock SLS AMG, Mercedes-Benz is expected to trim roughly 150 lbs. from the total curb weight of the SLS AMG Black Series Coupe. This same weight saving regime will be extended to the Roadster, though perhaps not with the same results. Liberal use of carbon fiber, and carbon fiber reinforced plastic, help cut the extra poundage. Yet the necessary chassis stiffening required for the Black Series Roadster is likely to add some weight back on, at least compared to the coupe. Carbon fiber will also be used for the large rear spoiler, along with the rear diffuser of the Black Series Roadster. A tasty-looking quad exhaust layout \u2013 first spotted on the Black Series Coupe prototype \u2013 is also certain to migrate to the drop-top.   Other performance features will include carbon ceramic disc brakes, lowered suspension, larger wheels and tires, and the aforementioned aerodynamic refinements. Pricing won&amp;#039;t be cheap, we&amp;#039;ve already estimated the SLS AMG Black Series Coupe should cost in the region of $350,000. The Roadster is going to demand a premium, of course, and most likely somewhere around the $380,000 you&amp;#039;d pay for the Aventador Roadster. "^^<http://www.w3.org/2001/XMLSchema#string>
