Watch the 1,500-hp Bugatti Chiron engine thrashing in a test rig

Tue, Mar 21 2017

Making sure the Bugatti Chiron is "Ring-Proof" takes a lot of testing. This rig, built by Bugatti's engineering and testing partner AVL-Schrick, demonstrates the hypercar's heart beating wildly while it's subjected to the g-forces it would experience on the Nurburgring. The footage was tweeted by James Mills of The Sunday Times.

Oil starvation is one of the key issues a car manufacturer has to tackle when making sure its product can withstand track time. For example, the Group B rally car derived all-aluminum XU9J4 engine in the first edition of the Peugeot 405 Mi16 suffers from oil starvation in prolonged track use in long corners. Due to insufficient oil pan baffling, the engine oil isn't evenly distributed when g-forces work their magic. By the time the 2.0-liter iron block XU10 version of the engine was rolled out in the facelifted car, the oil pan featured specially designed ports and baffles that restricted the oil's movement, making the engines less susceptible to crankshaft damage when driven spiritedly on a track.

But in that case we're talking about a 150-horsepower car, and the quad-turbocharged, W16-engined Chiron has 10 times as much power. When it was new, the engine in the $20,000 Peugeot reportedly cost the manufacturer nearly $5000 to produce, per unit. One imagines the Bugatti engines are far, far more expensive, and damaging one at a race track due to a manufacturer oversight must be a nightmare, hence this specially designed rig to iron out any Chiron bugs.
