Alfa Romeo is celebrating the impressive performance of the Giulia Quadrifoglio and Stelvio Quadrifoglio by announcing plans to unveil Nürburgring Editions at the Geneva Motor Show.

Designed to pay tribute to their Nürburgring lap records, the special editions have an exclusive Circuito Grey exterior with carbon fiber accents on the grille and mirror caps. The models have also been equipped with black wheels that are backed up by a carbon-ceramic braking system.

Moving into the cabin, drivers will find carbon fiber shelled Sparco racing seats with red contrast stitching. Designers also installed an individually numbered plaque and a leather / Alcantara steering wheel with carbon fiber inserts. Other highlights include 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.

Production will be limited to 108 units each and both models will be powered by 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 Stelvio Quadrifoglio to accelerate from 0-100 km/h (0-62 mph) in 3.8 seconds before hitting a top speed of 283 km/h (175 mph). Likewise, the Giulia Quadrifoglio hits 100 km/h (62 mph) in 3.9 seconds and tops out at 307 km/h (190 mph).

Alfa Romeo will also be showcasing two Stelvios which come equipped with new options. The first model has a leather-wrapped dashboard and leather door panels while the other has the new Performance Pack. It includes an Alfa Active Suspension, a locking rear differential and aluminum paddle shifters.

Lastly, Alfa Romeo will introduce the new 4C Competizione and Italia special editions. The Competizione is based on the 4C Coupe and it has a matte Vesuvio Grey exterior with a carbon fiber roof and rear spoiler. The model also has red brake calipers, an Akrapovič exhaust and 18- / 19-inch wheels with a dark finish.

Interior changes are limited but include leather seats with microfiber inserts and red contrast stitching. Other special touches include a leather / microfiber steering wheel, a numbered badge below the handbrake and an aluminum “Competizione” badge on the dashboard.

The 4C Italia goes in a different direction as it is based on the 4C Spider and has a Misano Blue paint job as well as yellow brake calipers. The model also has an Akrapovič exhaust and an exclusive “Spider Italia” sticker behind the doors.

The interior largely echoes the 4C Competizione but drivers will find yellow contrast stitching, an “Italia” plaque and an Alpine premium audio system with a subwoofer.

Production will be limited to 108 units a piece and both have a turbocharged 1.75-liter four-cylinder engine developing 240 PS (176 kW). This enables the cars to rocket from 0-100 km/h (0-62 mph) in 4.5 seconds before hitting a top speed of up to 258 km/h (160 mph).
