Alfa Romeo's Giulia Quadrifoglio gets the GTA treatment

Alfa Romeo will celebrate 110 years of building some of the world's most emotional driving machines with a brand-new Giulia Quadrifoglio GTA. GTA, which stands for "Gran Turismo Alleggerita," is a throwback to the 1965 Giulia Sprint GT, which first got the treatment. The new GTA and GTAm will elevate the Giulia's already driver-friendly formula to a whole new level. 

If the plain-Jane Giulia Quadrifoglio is a BMW M3 or Mercedes-AMG C63 competitor, the GTA is your Competition or "S" variant, respectively. It boasts more power, less weight, enhanced aero, a revised suspension, and a reworked chassis and interior designed to keep the driver in place and focused on one task and one task alone: driving fast. 

The wick on the GTA's 2.9-liter twin-turbocharged V6 has been turned up a bit, resulting in a new peak rating of 540 horsepower (up 30 from the base car). To reduce weight, Alfa replaced a host of exterior panels with carbon fiber equivalents. The carbon treatment extends to some other components, such as a the drive shaft. Alfa says the net reduction works out to 220 pounds. 

Outside, the aero has been completely revised with technical know-how provided by Sauber Engineering (of F1 renown). It also boasts 20-inch center-locking wheels and a titanium exhaust system. Alfa replaced many of the suspension bushings, the shocks and the springs with performance-friendly hardware.

The GTAm pushes the formula even farther. We hesitate to compare a sport sedan to a GT Coupe, but the relationship between GTA and GTAm is quite similar to that between the Porsche 911 GT3 and GT3 RS. Both are fundamentally the same car, but the latter compromises a great deal more of its daily drivability for the sake of improving its on-track feel and performance. 

With the GTAm, this included a set of carbon-backed front bucket seats with six-point harnesses, Lexan window inserts for the side and rear windows, and a rear seat delete. In place of the rear bench, you get a harness bar attached to a structural roll hoop, plus a handy little cubby for storing your custom Bell helmet in Alfa's GTA livery (which comes with the car, as well as an Alpinestars race suit, gloves and shoes, and a personalized Goodwool car cover). Checking in at just 3,350 pounds, the GTAm boasts a power-to-weight ratio of 6.2 pounds per horsepower, which Alfa says is the best in the class, enabling a 0-60 run in just 3.6 seconds.

The GTAm also receives further aero enhancements for improved track performance. The front splitter and carbon rear wing have both been optimized for downforce. Happily, the GTAm remains entirely street-legal.

Production of the GTA variants will be limited to just 500 units, "all numbered and certified and ready to take up their place alongside their 1965 forerunner as one of the most sought-after collector’s items," said Alfa's announcement.
