Order books for the Alfa Romeo Giulia Quadrifoglio NRing and Stelvio Quadrifoglio NRing Nurburgring Limited Editions open this weekend, as the two models are set to make their UK debut at Goodwood.

The former is priced from £82,500 OTR, whereas the Stelvio costs upwards of £89,500 OTR. According to Alfa Romeo, only 108 units of each models will be available for the EMEA region (Europe, Middle East, Africa).

Both limited edition models feature carbon-ceramic brakes, Sparco racing seats with red stitching and carbon shell structure, a gear stick with carbon insert by MOPAR, plus a leather and Alcantara steering wheel with carbon inserts. Meanwhile, the front ‘V’ grille surround and wing mirror caps are both wearing carbon fiber, just like the side skirts.

Inside, these NRing edition Alfas come with tinted windows, Adaptive Cruise Control, a Harman Kardon premium audio package, plus the Alfa Connect 3D Nav infotainment system with 8.8-inch screen, Apple CarPlay, Android Auto and DAB.

Both of these twin-turbo 2.9-liter V6-powered cars will feature a numbered badge in their carbon fiber dashboard insert and a unique Circuit Grey livery. While the Giulia will come with a new bare carbon roof, the Stelvio features an electrically operated panoramic roof.

If you happen to be one of the lucky 216 owners of either of these vehicles, Alfa Romeo will also treat you to a specific concierge service, assisting you throughout your experience with the car. Also, before you take delivery of the real thing, Alfa will send you a numbered 1:18 scale model, followed by a welcome kit comprised of Sparco racing gloves, soft shell jacket, custom sports bag, Quadrifoglio cuff-links and some original footwear by Car Shoe.

Owners will also be able to attend a sports driving technique course at the Nurburgring come next year.
