The Giulia Quadrifoglio is the performance flagship of the 952 range, powered by a Ferrari-derived 2.9-litre twin-turbo V6 producing 505 hp and capable of reaching 307 km/h. It lapped the Nurburgring Nordschleife in 7 minutes 32 seconds on its debut, a record for a production saloon at the time, and carries the historic four-leaf clover badge that Alfa Romeo has reserved for its fastest road cars since the 1960s.
