ALFA ROMEO is celebrating its' return to Formula One with two very special, limited edition models, one of which will arguably become the rarest Alfa on the roads of Britain.

Only three examples of the Alfa Romeo Racing special edition Stelvio Quadrifoglio will initially be available to UK buyers, priced at an extremely racy £96,500. Almost as exclusive will be the Alfa Romeo Racing edition of the Giulia Quadrifoglio with ten examples available priced from £89,500.

Under the bonnet of both models is a 2.9-litre V6 Bi-Turbopetrol engine. Tuned to deliver 520hp and 600Nm of torque it gives the Giulia Quadrifoglio a top speed of 191mph and acceleration from zero to 62mph in 3.9 seconds, while a top speed of 176mph and a sprint from zero to 62mph of 3.8 seconds is achieved by the Stelvio Quadrifoglio.

A Sauber engineered aero enhancement package adds wider side skirts, a unique front splitter, more prominent spoiler and side winglets on the front wings, all of which are functional rather than cosmetic and provide additional aerodynamic performance. A titanium exhaust gives a unique soundtrack and, in combination with fine tuning from Alfa Romeo's powerplant engineers, contributes to the 10hp power increase over the standard Quadrifoglio models.

The two specials mimic the white and red livery of the Alfa Romeo Racing F1 cars, while the racing inspiration continues inside with Sparco racing seats with red stitching and carbon shell structure, complemented by red seatbelts, an automatic gear selector with carbon insert and leather and Alcantara steering wheel also with carbon inserts.

While they may be designed to celebrate Alfa's return to F1 racing, the special editions are comprehensively and luxuriously equipped with adaptive cruise control, a Harman Kardon premium audio package and an infotainment and 3D navigation system with 8.8-inch screen. Each car will also be fitted with an exclusive Alfa Romeo Racing badge to commemorate the ten Alfa Romeo victories in Formula 1 in 1950 - 1951.

The special edition models are designed to celebrate the iconic Italian sporting brand's deepening participation and involvement in the Formula 1 world championship, in partnership with Sauber, now racing under the new official name of Alfa Romeo Racing.
