Abarth introduced its special edition 124 GT, which now includes a new lightweight, carbon-fiber hardtop roof. The roof is finished in naked carbon and weighs just 35 pounds. That includes the defroster for the rear window and an insulated lining. Fiat claims it improves the car's torsional rigidity by an unspecified amount. Other naked carbon details include the optional mirror caps and the rear blade spoiler. The hardtop is easily removed in a few steps and the 124 GT still retains its folding soft top, which is basically like always getting to have both chocolate and vanilla ice cream.

Fiat actually claims the Abarth 124 GT is the only car of its type offered with a carbon-fiber hardtop from the factory, which is easy to claim considering it's only a Miata and there's no other car like the Miata. The GT also gets new 17-inch O.Z. wheels painted in high-gloss black that, according to the company, cut 6.5 pounds from each corner compared to the standard wheels. Additional GT-specific exterior touches include standard Gunmetal mirror caps, along with an optional matte black hood meant to hark back classic Abarth rally cars. It even gets its own unique paint finish called AlpiOrientaliGrey.

Mechanically, there are no changes, meaning the 124 GT continues with FCA's 1.4-litre four-cylinder turbocharged engine, kicking out the jams to the tune of 160 horsepower and 184 pound-feet of torque, motivating the GT to 62 mph in 6.8 seconds on its way to a top speed of 144 mph. Both six-speed manual and six-speed automatic versions of the 124 GT will be available and the 'Record Monza' sports exhaust system is equipped as standard.
