Alfa has increased the power, quickness and price tags for the range-topping variants of its Giulia family of sedans, the GTA and GTAm.
The GTA is based on the model line’s former top performer, the Giulia Quadrifoglio, but its 2.9-liter V-6 engine delivers 532 hp, an increase of 29 hp on the Quadrifoglio.
The power increase was made possible by tweaking the car’s calibration. Alfa Romeo said its engineers reworked the piston cooling flow and the design of the rods. They also increase the air circulation in the engine cooling and transmission circuits.
The Giulia GTA accelerates from 0 to 100 kph (0-62 mph) in 3.6 seconds, which is 0.3 seconds faster than the Quadrifoglio.
The GTA weighs 1,605 kilograms while the GTAm is 25 kg lighter at 1,580. The Quadrifoglio has a curb weight of 1,620 kg.
GTA stands for Gran Turismo alleggerita, Italian for lightweight Gran Turismo; GTAm stands for GTA modificata, Italian for modified. Unlike the four-seat GTA, the GTAm is a two-seater with rollbar and a bigger rear spoiler.
Alfa Romeo will produce a combined 500 units of the Giulia GTA and GTAm. The starting prices in Italy are 175,000 euros for the GTA and 180,000 euros for the GTAm. The two variants will not be sold in the U.S., an Alfa Romeo spokesman said.
Alfa Romeo cut weight by using carbon fiber rather than heavier materials in the front bumpers and fenders, the front wheel arches and the GTA’s monocoque sports seats. Aluminum was used in the engine, doors, suspension and various composite materials in many other components. To further reduce weight in the GTAm, a polycarbonate was used in the side and rear window frames.
