Alfa Romeo and Zagato have a long-standing history of working together to produce some of the world's most beautiful cars. Their collaboration started way back in 1921 when the Alfa Romeo G1 Carrozzeria Zagato was born.

100 years and a few models later, the Italian brands are back with another unique creation. This time, they have turned a four-door sports sedan into a two-door retro coupe to celebrate the milestone.

Here's the Alfa Romeo Giulia SWB Zagato, and it's as exclusive as it gets. The one-off creation started life as a Giulia Quadrifoglio, but its wheelbase has been shortened to fit the Italian coachbuilder's carbon-fiber body.

In front, the signature Scudetto V-shaped grille has the Alfa Romeo logo integrated instead of the usual badging, while the three-point LED headlight design and massive intakes give the Giulia SWB an aggressive yet sexy styling.

Moving over to the side, Zagato expertly made the doors appear without any visible handles, while the fenders were neatly sculpted for a muscular look. Meanwhile, the rear end without the Alfa Romeo badge could be mistaken as an Aston Martin Vantage, but that's because the narrow light strip is a signature Zagato design.

Speaking of typical Zagato styling, the carbon fiber roof features a double bubble design and contrasts nicely with the special green paint job.

Inside, the Giulia SWB still has the dashboard from its Quadrifoglio donor car but has been upholstered with a black and green leather combination. The carbon bucket seats have been retained, sporting the Alfa Romeo lettering plus the Zagato logo on the headrests.

For its powertrain, the one-off Giulia SWB has the 2.9-liter twin-turbo V6 tweaked to the specifications of the GTAm, which means it produces 540 PS and 600 Nm of torque. But unlike the hardcore four-door sports sedan that has an 8-speed auto, purists will be glad to know that the Giulia SWB has a six-speed manual gearbox.

Pricing and other technical specifications have not been disclosed by Alfa Romeo, but it's been reported that the one-off Giulia SWB Zagato has been sold to a German customer who also owns a number of Zagato-penned models. If you ask how much, well we reckon the new owner spent big on this one, considering the GTAm already has a USD 200,000 price tag.
