worst motors of all time

VW v10 turbo diesel in the toureg. 750 ft/lbs of torque in a soccer mom SUV? I think they just gave up on it and kept the v6. Tension block diesels. Mis torque head and the block cracks. Yeah, Mazda 5 stroker, sum ***** was supercharged and had only 10HP more than standard Mazda motor.
