Alfa Romeo tantalized the Italian sportscar fanatic in all of us when it revealed the first images and details of the production version of its new 4C a couple of weeks ago. But while it gave us plenty to chew on, there were a few salient points it left out. Now it has filled in those blanks, and released a few new photos to go with it. Set to debut at the Geneva Motor Show in less than two weeks, the 4C packs Alfa’s latest 1.75-liter turbocharged, direct-injection four-cylinder engine.
