Fiat Chrysler's push to reinvigorate the Alfa Romeo brand took another step forward with the unveiling of its new top-end car, the Guilia.

Alfa Romeo, which returned to North America after a 20-year absence last year, had a high profile presentation in Milan, Italy, accompanied by tenor Andrea Bocelli signing opera.

The car has six-cylinders, 510 horsepower and can go from 0 to 60 mph in less than 4 seconds. The only Alfa Romeo now available in the United States, the 4C, has only 4 cylinders and 237 horsepower.
