TWO special edition Alfa Romeos are being launched to mark the brand's long standing relationship with Germany's legendary Nurburgring track.

Just 108 versions of the Stelvio Quadrifoglio NRING and the same number of Giulia Quadrifoglio NRING models will be produced and are aimed at collectors and hard core Alfa fans.

Finished in an exclusive grey livery standard equipment includes carbon-ceramic brakes, Sparco racing seats with red stitching and carbon shell structure, Mopar automatic transmission knob with carbon inserts and leather and Alcantara steering wheel with carbon inserts.

The Giulia model premieres a new bare carbon roof, while the Stelvio is equipped with an electrically operated panoramic sunroof.

The Stelvio Quadrifoglio is the first SUV in the Italian brand's history and holds the record for its segment, having completed the 20.832km of the Nordschleife in 7 minutes 51.7 seconds making it the fastest SUV to have lapped the famous circuit.

It has 2.9-litre V6 Bi-Turbo petrol engine with 510hp and torque of 600Nm powering a top speed of 176mph and acceleration from zero to 62mph in just 3.8 seconds.

The Giulia Quadrifoglio has a lap time of 7 minutes 32 seconds, achieved thanks to its handling, top speed of 191mph and acceleration from zero to 62mph in 3.9 seconds.

Owners will be given a numbered 1:18 scale model of their car prior to delivery and upon collection they will receive a welcome kit comprising Sparco racing gloves and customised soft shell jacket, sports bag in the Alfa Romeo pattern, Quadrifoglio cuff-links and original footwear created by Car Shoe.

They will also be offered the chance to attends a sports driving technique course on the Nurburgring circuit in 2019.

Alfa's relationship with the track goes back to 1932 when Rudolf Caracciola, driving a Gran Premio Tipo B, won ahead of two other Alfa Romeos with Nuvolari and Borzacchini at the wheel.

The Stelvio Quadrifoglio NRING and Giulia Quadrifoglio NRING Nurburgring limited editions are set to make their UK debut this summer at the Goodwood Festival of Speed in July where pricing and availability for the UK will be confirmed.
