Godolphin duo Hawkbill and Racing History were left to fill the places as Guignol sprang a 33-1 surprise in the Pastorius Grosser Preis Von Bayern at Munich.
The four-year-old, pacemaker for his Jean-Pierre Carvalho-trained stablemate Savoir Vivre, made all the running under an enterprising ride from Michael Cadeddu.
Guignol slipped the field after halfway, building up a lead of about eight lengths with Savoir Vivre leading the chase.
Though the pack closed in the final quarter-mile, Guignol had enough of an advantage to hang on. Charlie Appleby’s Hawkbill just held the Saeed bin Suroor-trained Racing History in a tight finish for second place, as the pair tried a mile and a half for the first time, but following a Stewards’ Enquiry was demoted to third.
Savoir Vivre weakened disappointingly in the closing stages, while David Simcock’s Algometer never got into a challenging position.
