The U.S.-Spec Alfa Romeo 4C Is 342 Pounds Heavier

You read that right. On the Atlantic cruise from Modena, Italy to the U.S., the 4C tacked on 342 pounds, and it wasn't from the all-you-can-eat steak and shrimp buffet.

The linebacker-plus weight gain is partially thanks to the feds, which required a slew of safety and structural improvements over the Euro-spec model. That includes a thicker carbon fiber tub, side airbags, and an adjustable passenger seat. But it also means that the claimed curb weight of 2,495 pounds includes an estimated 33-percent take rate on options, as mandated by the EPA.

But you can't entirely blame the federales.

Unlike the European's 2,153-pound 4C, the U.S. model gets standard A/C and radio. Which makes perfect sense for a sports car starting at $54k. But you still have to UNBOLT the driver seat to move it up and down.
