Mercedes SLS AMG Black Series – In Action
BrianZuk records an In Action video of a highly modified SLS Black Series by RENNtech. The video includes tons of action footage: in-car driving, flybys, accelerations, take offs, hard revs, various angles of the car, and more! Be sure to TURN UP YOUR SPEAKERS because this Black Series sounds incredible!
SLS AMG Coupé Black Series is a version of SLS AMG Coupé inspired by the racing version of the SLS AMG GT3. It includes increased engine power to 622 hp and decreased torque to 468 lb·ft, increased engine’s redline to 8000 rpm, fully revised high-speed valve train with modified camshafts, adapted cam geometry and optimised bucket tappets featuring a special coating which is otherwise exclusive to racing vehicles, modification of the intake air ducting (derestriction and adaptation to the new maximum engine speed), adaptation of the engine application and increase in peak pressure.
The vehicle is 150 lb lighter than the standard model. This is accomplished by increased use of carbon fibre in body panels, mechanical components, and the spaceframe. Further, a switch from steel to titanium for the exhaust reduces weight by 29 lb. The use of lithium-ion battery reduces weight by 18 lb.
The AMG SPEEDSHIFT DCT 7-speed sports transmission is installed 10mm lower in order to achieve a lower centre of gravity for the vehicle and is braced against the body by gas-filled struts in order to avoid stress cycles. The transmission’s “Sport plus” and “Manual” modes feature faster shifting speed. The downshifting throttle blips are more audible. The new temporary M mode enables the driver to activate manual mode without having to remove a hand from the steering wheel, by pressing the “up” or “down” shift paddle once.
