Frederick "Rikky" von Opel (born 14 October 1947) is a former racing driver, who competed under the Liechtenstein flag in Formula One from 1973 to 1974.
Both began at Paul Ricard in France, the eighth race of the 1973 season, with Opel qualifying his N173 25th and finishing 15th, three laps down.
More promising signs appeared to be on the horizon at Zandvoort for the Dutch Grand Prix where he qualified a very creditable 14th, ahead of former World Drivers' Champions Emerson Fittipaldi and Graham Hill.
Retiring with an oil leak in Spain, after qualifying 24th, and again a fortnight later in Belgium with a blown engine, from which he started 22nd, were not the lift in performance Opel wished for.
The promise was short-lived though, as failure to qualify next time out in France was the final straw for Brabham boss Bernie Ecclestone, and Opel was replaced by Carlos Pace.
He was born in the United States and lived in St. Moritz, Switzerland during his youth - often secretly challenging his cousin Gunter Sachs and friend Alexander Onassis to flat-out midnight bobsled runs at the St. Moritz-Celerina Olympic Bobrun.
He chose to represent Liechtenstein in racing despite having no connection to the country, and proclaimed before one of his Grands Prix that "When I win, I want to hear the German national anthem".
His exact whereabouts are unknown and his only contact with the outside world comes in the form of a post office box, the location of which is known by only a select few of his acquaintances.
