Reports in Automotive New Europe has the Alfa Romeo branch of FIAT developing a rear engine lightweight coupe for debut in the Geneva Auto Show. Known as the 4C GTA the coupe would retail in the range of $55K. Alfa plans to build 20,000 -25,000 units annually in one of FIAT's Italian factories. The 4C GTA was designed by Alfa's styling center in Turin and is said to be a rakish, very compact and extremely low two-seat coupe. Thanks to an innovative construction method, which combines carbon fiber and aluminum, the 4C GTA will be very lightweight. Alfa is targeting an 850kg (1,784 lbs) curb weight for the car. The 4C GTA would have an impressive power-to-weight ratio below 3.5kg/hp despite being powered by the 1.8-liter, four-cylinder gasoline direct-injection engine offered in the Giulietta with the horsepower boosted to more than 250 hp from 235 hp. Alfa Romeo teamed up with Italy's Dallara Automobili, which is one of the world's largest producer of racecars to create the 4C GTA. The car's structure is a development of the X-Bow, an extreme two-seat roadster launched in 2007 and engineered by Dallara for Austrian motorcycle maker KTM. Dallara developed a carbon fiber cockpit for the 4C GTA, which features front and rear aluminum sub-frames to house the engine, as well as carry the pushrod suspensions and to absorb deformation in crash tests. GTA is Alfa's acronym for Gran Turismo Alleggerita â€“ Lightened Grand Touring in Italian â€“ and was last used for the 147 GTA compact hatchback.
