Hottest New Cars at Detroit

Since the mid-engine 4C already has a superstiff carbon-fiber monocoque, no weighty structural bracings or modifications were required to change the coupe into a convertible. It also doesn’t hurt that the Spider is actually more of a targa reminiscent of the transcendent Lotus Elise. According to its maker, the Spider weighs just 22 pounds more than the coupe, which will still leave it on the good side of 2500 pounds according to our scales. (The two coupes we’ve tested rang in at 2471 and 2464 pounds.)
