A couple of camouflaged Alfa Romeo Giulia Quadrifoglio prototypes have been caught on camera testing hard on the Nordschleife.

Although the range-topping Giulia was unveiled almost two months ago, Alfa Romeo is still keeping a full body disguise on their prototypes and now two of them were spotted on the 'Ring during the industry pool testing. You will notice the cars are being pushed to their limits and due to heavy braking the warning lights come on from time to time.

It seems Alfa Romeo still has some fine tuning to do which doesn't really come as a surprise since the Giulia was developed in just two and a half years, so there are still some issues to sort out before the model reaches dealerships. The entire Giulia lineup will be showcased in about three weeks at IAA in Frankfurt where hopefully Alfa Romeo will provide details about availability and pricing.

The crown jewel of the range will obviously be the Quadrifoglio version developed to go head to head with high-performance compact sedans such as the BMW M3 and Mercedes-AMG C63 S. On paper it appears to be quicker than the two thanks to a lightweight construction and a Ferrari-derived 2.9-liter V6 bi-turbo engine with 510 PS, enough for a 0-62 mph (0-100 km/h) run in 3.9 seconds and a rumored top speed of 200 mph (321 km/h).

It's a model that can single-handedly make or break Alfa Romeo so hopefully the Giulia will be a great success in order to ensure a bright future for the legendary Italian marque.
