Mercedes-Benz SLS AMG Black Series doesn’t have a straight-eight, however it will have the foremost potent six.2-liter V-8 Mercedes-Benz has ever designed. this is often probably the last naturally aspirated gasp of the brand’s heavy-breathing M159 engine we’ll ever hear.
As a retirement gift, Mercedes-Benz SLS AMG has given the engine new camshafts, specially coated bucket tappets, a a lot of economical intake tract, more-durable rotating shaft bearings, and a Ti exhaust that shaves twenty nine pounds. The mighty V-8 goes out barking, spitting, and spinning all the far to 8000 rate. All 622 power unit (up from 583 within the SLS GT) show up at 7400 rate with 468 pound-feet of force coming back in at 5500 rate. AN angry Sprint Cup car–like thrum pulses out of the Black’s four exhaust tips to warn the onerous of hearing.

Turn the transmission-control knob to the “race start” setting and also the seven-speed dual-clutch shell is fit for launch. along with your feet on the brake and accelerator, the engine revs to 3000 rate, and also the clutch dumps after you start out the brake. Weight distribution is therefore biased it’s nearly intolerant, with a meaning fifty four.1 p.c over the rear tires. not to mention AN electronically controlled limited-slip differential and sticky rubber, this permits for terribly repeatable three.2-second zero-to-60 sprints. Keep it buried, and also the quarter-mile falls in eleven.2 seconds at 128 mph, identical time as a Lamborghini Gallardo.
