This has to be one of the most unique builds we’ve ever come across. Gary Martins from Johannesburg, South Africa, is an ex BMW Master Technician who now owns his own business, Grease Monkey Motors.

He has a passion for diesel racecars and this is his second custom creation. Borrowing the 3.0l-litre triple-turbo engine from a BMW X5 M50d, and starting off with a 220d donor car, he set about creating this absolute diesel monster.

With 435kW (580Nm) and over 1000Nm of torque, this is a car designed for track racing, hill climbs drag racing and just plain old hooning, which Gary does with enthusiasm for us and our cameras at The Rock Raceway.
