Alfa Romeo currently holds the Nürburgring lap record for SUVs (with its Stelvio Quadrifoglio), having earlier claimed the fastest time for a sedan (the Giulia QV has since lost the title to the Jaguar XE SV Project 8). And now the Italian automaker has released a pair of special-edition models to celebrate its on-track achievements.

Both the sedan and SUV are lathered in carbon-fibre bits, with each furthermore featuring a dark grey paint scheme and special "NRING" badging. Alfa says it will build just 108 examples of each, adding items such as carbon-ceramic brakes, Sparco racing seats, a Mopar automatic shifter and a steering wheel clad in leather and Alcantara with carbon inserts. Additionally, the Giulia sedan is fitted with an exposed carbon-fibre roof. No changes have been made to the turbocharged 2,9-litre V6 that does duty in both the Giulia Quadrifoglio and the Stelvio Quadrifoglio.

In addition, there are a few more packs revealed for the rest of the Alfa line-up. The Stelvio Super, which boasts the 147 kW/206 kW turbocharged 2,0-litre four-cylinder engine, can now be fitted with a performance pack, adding active suspension, self-locking rear mechanical differential and solid aluminium paddle shifters.

Furthermore, Alfa has announced that the 206 kW Giulia Veloce (which is scheduled to arrive in South Africa in the second quarter of 2018) will soon be available in Ti ("Turismo internazionale") trim. This adds a black roof, 19-inch five-spoke alloy wheels and red brake calipers, while the cabin gains a leather-clad dashboard with carbon inserts, leather and Alcantara seats with black stitching, and backlit branded kick-plates.

Lastly, Alfa Romeo has revealed Competizione and Italia versions of its 4C Coupé and Spider. The two new variants of the mid-engined performance car gain a matte Vesuvio grey paint with carbon-fibre accents, 18-inch front and 19-inch rear dark-finish five-spoke alloy wheels and Akrapovič titanium exhausts. Inside each, you'll find a set of leather and microfibre seats, a steering wheel with red stitching and a plaque of authentication. Just 108 units of each model will be produced.
