One again, our friend Bozzy has produced another great video from Italy’s Monza Circuit. This piece of footage was recorded during the first round of the 2012 Blancpain Endurance Series and focuses on BMW’s striking Z4 GT3 racecar. You’ll need to turn your speakers right up to fully appreciate the symphony from that 4.4-litre V8 engine, which develops a healthy 384 kW (515 hp) and 515 Nm of torque.
