This is the B55, a silly one-off project by workers at Mercedes’ Rastatt plant that involved shoving an old “55” AMG engine into a new B-Class, running a driveshaft through the “sandwich floor” and hooking it up to an old E-Class wagon rear axle. The result: 383 HP, a 0-60 time in the 5 second range, and what Autocar terms “surprisingly mature dynamic properties.” Possibly even more surprisingly, the whole project was done without a lick of help from the nutters at AMG, and required no frame modifications. Best of all is how  comfortingly old-school the project is: the days of turning an FWD compact car into a V8 RWD beast are rapidly drawing to a close. Need proof? For the next-generation of A/B-Class, AMG is going in a very different direction, creating an “A25 AMG” which will use a two liter turbocharged four-banger, putting around 300 HP through a dual-clutch transmission and Haldex AWD. This “STI by AMG” will doubtless be infinitely more practical, efficient and useable than the B55’s old-school V8/RWD setup… but more than a few gearheads will be sad to see these kinds of unhinged anachronisms ride off into the sunset.
