Our own Jay Shoemaker called it: Mercedes' in-house tuner is practicing its black magic on more models. Pistonheads reports that AMG is set to unleash the SLK 55 AMG Black Series on suspecting, well-heeled hoons. To banish/bolster the ride's rep as the ultimate hairdresser/mistress' car, the Boys from Affalterbach have upgraded the [once] uber-SLK's 5.5-liter V8 to 400hp, and blessed it with enough twist to keep the traction control Nanny stuttering for days. (We're torquing zero to 60mph in 4.5 seconds.) Since they couldn't throw out the SLK's back seat, AMG lightened the load by fixing the SLK's folding tin top in place and binning all those meticulous motors and bling-bringing braces. Suspension mods, bigger brakes, larger shoes, carbon in the cabin and away you go; proving that a nose heavy German two-door can be just as breathtakingly bonkers as an ass-engined German two-door.
