Following a preview last month, Alfa Romeo has unveiled the new Giulia Quadrifoglio and Stelvio Quadrifoglio Nürburgring Editions at the Geneva Motor Show.

Dubbed the NRING Editions, the models are dressed in exclusive Circuito Grey paint which is echoed by their dark wheels that cover a carbon-ceramic braking system. The dark theme continues elsewhere as designers installed carbon fiber mirror caps as well as a carbon fiber grille insert.

The interior largely carries over but there are a handful of special touches which separate the NRING Editions from lesser variants. Highlights include a leather and Alcantara wrapped steering wheel with carbon fiber accents as well as carbon fiber shelled Sparco racing seats with red contrast stitching.

Drivers will also find an individually numbered plaque, a Harman Kardon premium audio system and an 8.8-inch infotainment system with GPS navigation as well as Android Auto and Apple CarPlay compatibility.

Like the standard models, the NRING Editions are equipped with a twin-turbo 2.9-liter V6 engine that produces 510 PS (375 kW) and 600 Nm (442 lb-ft) of torque. It enables the all-wheel drive Stelvio Quadrifoglio to rocket from 0-100 km/h (0-62 mph) in 3.8 seconds before topping out at 283 km/h (175 mph).

The Giulia Quadrifoglio is a tad slower as the dash from 0-100 km/h (0-62 mph) takes 3.9 seconds but it has a higher top speed of 307 km/h (190 mph).

While the models don’t hold the overall Nürburgring lap record, the Giulia Quadrifoglio lapped the famed course in 7 minutes and 32 seconds to become the fastest four-door sedan on the Green Hell. Approximately one year later, the Stelvio Quadrifoglio completed the same task in 7 minutes and 51.7 seconds to claim a new record for crossovers and SUVs.

Production will be limited to 108 units a piece as “one for each year of the history of Alfa Romeo.”
