For around $160,000, German tuning shop Hartge will deliver a BMW 3-Series that's been fitted with a moderately juiced V10 from the M5. The resultant 550-hp H50 isn't exactly a moderate runner. In fact, if you take this video at face value, the H50 is apparently best driven sideways. See, there's this technique called "opposite lock" and ... oh just forget it.
